Our RSM UK Payroll review breaks down what you get and what it actually costs.

UK Outsourced Payroll Providers Compared

UK outsourced payroll costs range from free (Employment Hero basic) to $599/employee/month (Deel EOR), with most managed bureaux offering custom quotes for 30+ employees.

Outsourced payroll services in the UK range from free basic platforms to over £500 per month for fully managed bureau services, depending on headcount and service level. For small businesses with fewer than 50 employees, software-only solutions like Moneysoft (from £15 per month) and Staffology (from £1 per payslip) offer the most affordable option. Managed payroll bureaux such as Moorepay and PayFit handle the entire payroll process including RTI submissions, pension auto-enrolment, and year-end reporting.

Managed bureaux typically charge £5 to £15 per employee per month. The eight providers compared in this guide cover every service model from self-service software to full outsourcing, each verified for HMRC compliance, auto-enrolment capability, and integration with popular accounting platforms. Businesses switching from manual payroll to an outsourced provider save an average of 40 hours per month on payroll administration.

The table below compares all 8 providers side by side. Pricing varies significantly depending on whether you choose self-service software, a managed bureau, or a global EOR service. Managed bureaux like Moorepay and ADP provide custom quotes based on headcount and service level, while software providers like Sage and Xero publish transparent per-employee pricing.

Each provider targets a different segment of the market. If you already know what you need – managed service, self-run software, or international EOR – jump to the relevant section below. If you are unsure, read our decision guide further down the page.

A few patterns stand out from the comparison. The cheapest entry point is Employment Hero’s free payroll plan, followed by Xero’s £1.50/employee/month payroll add-on. For businesses willing to pay more for a fully managed service, Moorepay and PayEscape offer end-to-end bureau processing without the steep enterprise pricing of ADP. The biggest jump comes with Deel’s EOR service at $599/employee/month – a premium justified only by the legal and compliance burden of hiring in countries where you have no entity.

Best Managed Payroll Bureaux

Managed payroll bureaux like Moorepay and PayEscape handle your entire payroll process, from HMRC submissions to payslip distribution, for a monthly per-employee fee.

A managed payroll bureau takes full responsibility for processing your payroll. You provide employee data – new starters, leavers, salary changes, overtime, and absence records – and the bureau handles calculations, HMRC Real Time Information (RTI) submissions, payslip generation, pension auto-enrolment, and year-end reporting. This is the right choice for businesses that want to remove payroll risk entirely from their operations.

The key advantage of a managed bureau over payroll software is accountability. When your bureau makes an error, they fix it and bear the cost. When you make an error using software, you bear the cost yourself. For businesses processing complex pay structures – multiple pay frequencies, shift allowances, overtime rules, or salary sacrifice schemes – this risk transfer alone justifies the cost difference.

The three providers in this section – Moorepay, PayEscape, and ADP – each serve different business sizes and complexity levels. Moorepay targets the mid-market (30-1,000 employees), PayEscape offers flexible month-to-month contracts for businesses of all sizes, and ADP handles enterprise and global payroll for organisations with hundreds or thousands of staff. For businesses in education, financial services, or retail, Cintra (CIPP 2024 Payroll Service Provider of the Year) also offers fully managed bureau processing with ISO 27001 certification and 40+ years of payroll heritage.

Moorepay is a UK-based managed payroll bureau that combines outsourced payroll processing with optional HR software. The company won CIPP Payroll Service Provider of the Year 2023 and claims a 99.9% payslip accuracy rate, which sets it apart from most competitors who do not publish accuracy guarantees. Moorepay holds both ISO 9001 (quality management) and ISO 27001 (information security) certifications, plus Bacs Approved Bureau status and full HMRC recognition.

What makes Moorepay our Editor’s Pick is the combination of service quality guarantees and accreditations that no other mid-market provider matches. The 99.9% accuracy claim is backed by ISO-certified quality management processes, and Bacs Approved Bureau status means Moorepay meets the Payment Systems Regulator’s standards for handling direct payments. For businesses that have been burned by payroll errors or unreliable providers, these credentials provide genuine reassurance.

Every Moorepay client is assigned a dedicated UK-based account manager who knows your business, your pay schedules, and your specific requirements. This is a significant differentiator from providers that route support through call centres with rotating staff. Your account manager handles onboarding, ongoing queries, and acts as your single point of contact for any payroll issues.

Key features include:

• Dedicated UK-based account manager assigned to your business for ongoing payroll support
• Implementation from as little as 4 weeks – faster than most enterprise providers who typically quote 8-12 weeks
• Both software and managed service options – choose self-service or fully outsourced depending on your team’s capability
• Bacs Approved Bureau for secure, direct payment processing to employee bank accounts
• Auto-enrolment and pension management handled as part of the service, including communications to employees
• Year-end reporting and P60 distribution included in managed packages
• Flexible employee range targeting 30-1,000 employees, though the company can accommodate businesses outside this range

Pricing: Quote-based. Moorepay does not publish pricing online, so you will need to request a tailored quote based on your headcount and service requirements. Quotes typically factor in employee count, pay frequency (weekly, fortnightly, or monthly), and whether you want software-only or fully managed processing.

Best for: Mid-sized UK businesses with 30-1,000 employees who want a fully managed, award-winning payroll bureau with dedicated account management and ISO-certified security. Moorepay is particularly well-suited to businesses in regulated industries (financial services, healthcare, legal) where payroll accuracy and data security are non-negotiable. Read our full Moorepay HR review for a detailed breakdown of their HR platform.

PayEscape has been providing cloud-based payroll, HR, and time management services since 2006. The company differentiates itself through monthly rolling contracts with no lock-in period – a significant advantage over competitors that require 12 or 24-month commitments. PayEscape maintains a 98% client retention rate, which suggests that businesses stay because the service delivers, not because they are contractually trapped.

The team is staffed by CIPP and CIPD certified professionals, providing qualified expertise across both payroll processing and HR advisory. CIPP certification (Chartered Institute of Payroll Professionals) means the payroll team has passed rigorous industry exams, while CIPD certification covers HR best practice. PayEscape holds a 4.5 out of 5 rating on Trustpilot from over 150 reviews, placing it among the highest-rated payroll providers in the UK for customer satisfaction.

The monthly rolling contract model deserves particular attention. Many managed payroll providers lock businesses into annual or multi-year agreements, making it expensive to switch if the service deteriorates. PayEscape’s month-to-month structure means you can leave at any time with no penalties or exit fees. Combined with no annual price indexation (your rate stays fixed, unlike some competitors who increase prices annually), this makes PayEscape a low-risk choice for businesses trying outsourced payroll for the first time.

Key features include:

• Monthly rolling contracts – cancel any time with no penalties or exit fees
• Cloud-based platform covering payroll, HR, and time management in one system
• CIPP and CIPD certified payroll professionals handling your account
• No annual price indexation – your rate stays stable year over year
• HMRC-compliant RTI submissions and auto-enrolment management
• Integrated time and attendance tracking built into the same platform as payroll

Pricing: From approximately £52 per month. Managed payroll pricing is quote-based and depends on headcount and pay frequency. The starting price covers a small team, with per-employee costs varying based on service complexity.

Best for: Businesses that want flexibility with month-to-month contracts and proven service quality, without being locked into long-term agreements. PayEscape is an excellent choice for businesses switching from a disappointing payroll provider – you can trial the service without committing to a year-long contract.

ADP is one of the largest payroll and human capital management companies in the world, serving over 1 million customers globally across 140+ countries with 75+ years of experience. For UK businesses with complex payroll needs – particularly those operating internationally – ADP offers scale and infrastructure that smaller providers cannot match.

ADP structures its UK offering into four tiered products based on company size. This tiered approach means you get a product designed for your specific scale rather than a one-size-fits-all solution that is either too basic or too complex:

• iHCM – designed for businesses with 1-199 employees, combining payroll with core HR functions including recruitment, onboarding, and performance management
• Celergo – targets 200-1,000 employees, adding multi-country payroll capabilities and consolidated reporting across jurisdictions
• Enterprise Payroll – built for 1,000+ employees with complex pay structures, multiple collective bargaining agreements, and advanced reporting needs
• Global Payroll – multi-country payroll processing with 13 service centres worldwide and support in 45 languages, designed for multinationals

The depth of ADP’s infrastructure is its primary advantage. With 13 service centres globally, ADP can process payroll in local time zones, handle country-specific tax regulations, and provide localised support. For UK businesses expanding into Europe, the Middle East, or Asia-Pacific, ADP can consolidate all payroll reporting into a single dashboard while maintaining local compliance in each country.

Pricing: Quote-based across all products. ADP does not publish pricing, and costs vary significantly based on employee count, number of countries, pay complexity, and service level. Expect enterprise-level pricing – ADP is not positioned as a budget option, but its scale and reliability justify the investment for large organisations.

Best for: Large UK businesses with 200+ employees, especially those with international payroll requirements across multiple countries and jurisdictions. ADP is overkill for a 20-person UK-only business, but for a 500-employee company operating in five countries, it is difficult to match.

Best Payroll Software for UK Businesses

Sage, Employment Hero, and Xero offer the best UK payroll software, with prices starting from free (Employment Hero) to £20/month (Sage Essentials, 10 employees included) for small businesses.

For the full pricing picture, see our payroll software costs breakdown.

Payroll software puts you in control of processing. You run pay runs, generate payslips, and submit RTI to HMRC yourself – but the software automates the calculations, tax deductions, and compliance checks. This approach works well for businesses with a capable office manager or bookkeeper, and it costs significantly less than a managed bureau.

The trade-off is straightforward: you save money but take on the responsibility. If you enter an employee’s tax code incorrectly, the software will process the wrong amount – and the liability sits with you, not the provider. For straightforward payroll (salaried employees, standard PAYE, no complex allowances), this risk is minimal. For businesses with variable pay, multiple locations, or complex pension arrangements, a managed bureau may be worth the additional cost.

The three software providers below each take a different approach: Employment Hero bundles payroll with a full HR platform (including a free tier), Sage offers standalone payroll with deep accounting integration, and Xero provides payroll as a low-cost add-on for businesses already using Xero for accounting.

Employment Hero is an all-in-one HR, payroll, and hiring platform that stands out for offering a free payroll plan – the only provider on this list to do so. The free tier includes automated pay runs, digital payslips, and PensionSync integration, making it a genuine option for startups and micro-businesses watching every pound. Unlike free trials that expire after 14 or 30 days, Employment Hero’s free plan is a permanent tier with no time limit.

Paid HR plans have minimum monthly charges: HR Standard starts at £90/month, scaling on a per-employee basis (~£4-5/employee/month at scale). The top tier, Employment Unlimited at £19/employee/month, adds managed payroll, phone support, Employee Assistance Programme (EAP), and HR Advisory. This tiered structure means you can upgrade as your business grows without migrating to a different platform – but smaller teams should factor in the minimum billing floor.

The platform also includes features that go beyond basic payroll. SmartMatch on the top tier provides unlimited hiring with AI-powered candidate matching – part of a growing wave of AI tools reshaping UK business operations. Earned Wage Access allows employees to access a portion of their earned pay before payday – a benefit that can reduce financial stress and improve retention without costing the employer anything. API access on Platinum and above enables integration with your existing business systems.

The full pricing breakdown across all four tiers:

• Free payroll plan with automated pay runs, payslips, and PensionSync
• HR Standard from £90/month minimum (~£4-5/emp/mo at scale) with core HR, leave management, document storage, and onboarding workflows
• HR Premium from £140/month minimum adding performance reviews, employee surveys, and goals tracking
• HR Platinum from £190/month minimum with API access, advanced reporting, and custom workflows
• Employment Unlimited at £19/employee/month including managed payroll, EAP, HR Advisory, SmartMatch hiring, and phone support

For a 50-employee business, Employment Hero HR Standard would cost approximately £200-250 per month for a combined HR and payroll platform (above the £90 minimum). Compare that to Sage Essentials at £72/month (payroll only, no HR) or a managed bureau at £200-£1,250/month. The value proposition is strong for businesses that need both HR and payroll in one system, though smaller teams (under ~20 employees) may find the minimum billing exceeds the per-employee rate.

Best for: UK SMEs that want HR, payroll, and hiring in a single platform, with the flexibility to start free and scale up. Particularly strong for businesses that value a modern employee experience with features like Earned Wage Access. For a detailed look at their HR capabilities, read our Employment Hero review, or compare it against other platforms in our best HR software guide.

Sage is one of the most established names in UK business software, and its cloud payroll product offers genuine value for small and medium businesses. The Essentials plan starts from £20 per month with 10 employees included, making it one of the most affordable HMRC-recognised payroll solutions available. Sage is currently offering 90% off the first 3 months, which drops the entry price to just £2 per month during the promotional period.

Sage payroll is a DIY software tool, not a managed service. You run the payroll yourself, but the software handles tax calculations, National Insurance contributions, RTI submissions to HMRC, pension auto-enrolment, and payslip generation automatically. The real strength of Sage is its seamless integration with Sage accounting software – if you already use Sage for bookkeeping, adding payroll keeps everything in one ecosystem and eliminates the need for manual journal entries between systems.

The employee self-service portal on Standard and Premium plans reduces the administrative burden on your payroll administrator. Employees can view their payslips, update personal details, and access P60s themselves – cutting out the back-and-forth emails that eat into processing time.

Pricing across the three tiers:

• Essentials from £20/month – 10 employees included, £1.30 per additional employee. Core payroll processing, RTI submissions, and payslip generation
• Standard from £40/month – 10 employees included, £3.30 per additional employee. Adds employee self-service portal and enhanced reporting
• Premium from £60/month – 10 employees included, £5.30 per additional employee. Adds advanced analytics, priority phone support, and custom reports

To put the cost in perspective: a 20-employee business on Sage Essentials would pay £20 + (10 x £1.30) = £33 per month. The same business on Sage Premium would pay £60 + (10 x £5.30) = £113 per month. Both are significantly cheaper than managed bureau alternatives, but you are taking on the processing responsibility yourself.

Best for: Small to medium UK businesses that want affordable, HMRC-recognised payroll software with strong accounting integration. Particularly suited to businesses already using Sage for their accounts. For more on Sage’s HR capabilities, read our Sage HR review. Accountants managing multiple clients should also see our guide to payroll software for accountants.

Xero’s payroll is a per-employee add-on to its cloud accounting platform, making it cost-effective for businesses already using Xero for their books. Payroll costs £1.50 per employee per month on Ignite, Grow, and Comprehensive plans (or £1.00/employee/month on Ultimate), which sits on top of your existing Xero accounting subscription. This makes it one of the cheapest payroll options for existing Xero users – and the simplest to set up, since your employee and financial data is already in the system.

The payroll add-on is HMRC-recognised and handles automatic RTI submissions, flexible pay cycles (weekly, fortnightly, four-weekly, or monthly), automatic payslip generation, built-in timesheets, and workplace pension management. Employees get access to the Xero Me employee app for self-service access to payslips, leave requests, and personal information updates.

The main advantage of Xero payroll is integration depth. Payroll costs flow directly into your Xero accounts, journal entries are created automatically, and your profit and loss statement updates in real time after each pay run. For businesses that currently export payroll data from one system and import it into Xero manually, this automation eliminates a significant source of errors and wasted time.

Payroll add-on pricing tiers:

• Ignite, Grow, or Comprehensive plan – £1.50/employee/month for HMRC-compliant payroll, RTI submissions, and payslip generation
• Ultimate plan – £1.00/employee/month including payroll, analytics, all premium features, and priority support

The limitation of Xero payroll is scope. It handles up to 200 employees and is designed as a payroll add-on for small teams, not a standalone payroll platform. If you do not already use Xero for accounting, you would need to subscribe to a Xero accounting plan first (from £15/month for Starter), which changes the cost equation. And for larger or more complex payroll needs, a dedicated platform like Sage or a managed bureau will offer more depth.

Best for: Small UK businesses already using Xero for accounting who want to add payroll without switching platforms or paying for a separate system. Particularly strong for freelancers, micro-businesses, and small teams under 20 employees who value simplicity over advanced features.

Best for Specialist Needs

Deel specialises in global EOR payroll for international teams in 150+ countries, while Access People targets mid-market and enterprise UK organisations needing integrated HR.

Not every business fits neatly into the “managed bureau” or “self-service software” categories. The two providers in this section serve specific use cases: Deel handles payroll for companies hiring across borders without local entities, and Access People provides an integrated enterprise platform for mid-market UK organisations that need payroll and HR in a single system.

Deel solves a problem that traditional UK payroll providers cannot: paying employees and contractors in countries where your business has no legal entity. The platform operates across 150+ countries with support for 150+ currencies, offering global payroll processing, Employer of Record (EOR) services, and contractor management from a single dashboard.

For UK businesses expanding internationally, Deel’s EOR service means you can hire employees in new markets without setting up local subsidiaries. Deel becomes the legal employer in each country, handling local tax, benefits, and compliance while your team reports to you operationally. Setting up a legal entity in a new country typically takes 3-6 months and costs £10,000-£50,000 in legal and accounting fees. Deel’s EOR eliminates that entirely, allowing you to hire in a new country within days.

Deel also handles contractor compliance – a growing concern for UK businesses working with international freelancers. Misclassifying a contractor as an employee (or vice versa) can trigger significant tax liabilities and penalties in both the UK and the contractor’s country. Deel’s platform assesses classification risk and manages compliant contracts across jurisdictions.

Pricing is transparent and published (in USD):

• Global Payroll – from $29 per employee per month for businesses with their own entities in each country
• Contractor Management – from $49 per contractor per month for compliant international contractor payments and contracts
• Employer of Record (EOR) – from $599 per employee per month for hiring without local entities, including all local employment obligations
• PEO – from $95 per employee per month for co-employment in specific markets where PEO is the preferred structure

The EOR pricing at $599/employee/month looks expensive in isolation, but compare it to the alternative: establishing a local entity (from £10,000 in setup costs), hiring a local accountant, managing local tax filings, and maintaining compliance with country-specific employment law. For small teams in new markets (1-10 employees per country), the EOR model is almost always cheaper and faster.

Best for: UK businesses with international teams or plans to hire in new countries. Particularly valuable for tech companies, remote-first organisations, and businesses expanding into markets where establishing a local entity is impractical. For businesses comparing global HR platforms, Rippling offers a similar international scope – see our Rippling review for a comparison.

Access People is the payroll and HR division of The Access Group, one of the UK’s largest business software providers. The platform combines payroll processing with a full HR suite, making it a strong choice for mid-market and enterprise businesses that want both functions in a single, tightly integrated system rather than bolting together separate tools from different vendors.

The platform’s strength lies in its reporting and analytics capabilities and its high level of customisation. Businesses with complex organisational structures, multiple pay groups, or specific reporting requirements will find more flexibility here than with off-the-shelf solutions like Sage or Xero. Access People is designed for organisations that have outgrown basic payroll tools but do not need the global scale of ADP.

Being part of The Access Group gives Access People a broader ecosystem advantage. If your business already uses Access products for finance, ERP, or business intelligence, adding Access People for payroll and HR creates a unified data environment. Workforce costs flow directly into financial reporting, headcount data feeds into operational planning, and you deal with a single vendor relationship instead of managing multiple contracts.

Key features include:

• Integrated HR and payroll in a single enterprise platform with shared data and workflows
• Advanced reporting and analytics for workforce insights, cost analysis, and payroll auditing
• Highly customisable workflows, pay rules, approval chains, and organisational hierarchies
• Part of The Access Group – backed by an established UK technology company with a broad product portfolio
• Employee and manager self-service portals reducing the administrative load on your HR and payroll teams
• Scalable architecture supporting complex multi-site, multi-entity business structures

Pricing: Quote-based. Industry pricing for comparable enterprise platforms ranges from £4-£25 per employee per month, depending on modules selected and service level. Expect pricing towards the higher end if you require the full HR and payroll suite with customisation and dedicated support.

Best for: Mid-market and enterprise UK organisations with 100-5,000 employees that need integrated payroll and HR with strong reporting, customisation, and the backing of an established UK software provider. Particularly suitable for multi-site businesses with complex organisational structures.

How to Choose an Outsourced Payroll Provider

Choose a managed bureau if you want hands-off payroll processing, or software if you prefer running payroll in-house with HMRC-compliant tools.

The first decision is whether you want outsourced services, software, or both. A managed payroll bureau (Moorepay, PayEscape, ADP, Cintra) handles everything – you provide employee data, they run payroll, submit to HMRC, distribute payslips, and manage pensions. This suits businesses that lack in-house payroll expertise or want to eliminate compliance risk entirely. Payroll software (Sage, Xero, Employment Hero) gives you the tools to process payroll yourself, with automated calculations and HMRC submissions. This suits businesses with a capable office manager or bookkeeper who can run payroll monthly. Employment Hero bridges both worlds by offering managed payroll on its top tier alongside self-service options on lower plans.

Company size significantly narrows your options. Businesses with fewer than 30 employees will find the best value with Sage (from £20/month, 10 employees included), Xero (£1.50/employee/month add-on), or Employment Hero (free tier available). At this scale, payroll is typically straightforward enough to handle with software.

Mid-sized businesses with 30-1,000 employees should look at Moorepay or PayEscape for managed services, or Employment Hero’s premium tiers for a combined HR and payroll platform. The complexity of managing 50+ employees – multiple pay frequencies, starters and leavers each month, statutory payments – makes a managed bureau increasingly attractive. Enterprise organisations with 1,000+ staff or multi-country operations need the scale of ADP or Access People, where the provider’s infrastructure can handle thousands of payslips across multiple entities and jurisdictions.

Budget ranges dramatically across these providers. At the free end, Employment Hero’s basic payroll plan costs nothing. Sage starts from £20 per month with 10 employees included. Xero’s payroll add-on costs £1.50 per employee per month (but requires an existing Xero accounting subscription). Managed bureaux like Moorepay and PayEscape (from approximately £52/month) cost more but remove the burden of processing payroll yourself.

At the premium end, Deel’s EOR service costs from $599 per employee per month – justified only when you need to hire in countries where you have no legal entity. As a rule of thumb, expect to pay £4-£15 per employee per month for quality managed payroll in the UK, with enterprise and global services commanding higher fees.

Every provider on this list handles the core compliance requirements: HMRC Real Time Information (RTI) submissions, automatic pension auto-enrolment, tax and National Insurance calculations, and year-end reporting (P60s, P11Ds). The difference is whether you want software that automates these processes for you to run, or a bureau that handles them entirely on your behalf. If your business operates in a regulated industry or has complex pay structures (shift patterns, overtime, multiple pay groups, salary sacrifice, benefits in kind), a managed bureau reduces the risk of costly errors. HMRC penalties for late or inaccurate RTI submissions start at £100 per month for every 50 employees and escalate from there.

For businesses with international payroll needs, the choice narrows to Deel (150+ countries, EOR available) or ADP (140+ countries, enterprise-scale). UK-only businesses should not pay a premium for global capabilities they will not use – stick with a UK-focused provider like Moorepay, Sage, or Employment Hero instead. If you currently have employees in the UK and plan to hire in one or two additional countries within the next 12 months, Deel is the faster and more cost-effective option. If you already operate across five or more countries with established entities, ADP’s consolidated reporting and local service centres offer more depth.

Outsourced vs In-House Payroll: Which Is Right for You?

Outsourcing payroll costs £4-£25 per employee per month but saves an average of 18 hours per month for a 50-person business compared to in-house processing.

The cost comparison between outsourced and in-house payroll often favours outsourcing more than businesses expect. A part-time payroll administrator in the UK earns £12,000-£18,000 per year. A full-time payroll manager commands £30,000-£45,000 depending on experience and location. A managed payroll bureau for 50 employees might cost £200-£1,250 per month (£4-£25 per employee), or £2,400-£15,000 annually. For many mid-sized businesses, outsourcing costs the same as or less than an in-house hire – and you get specialist expertise, HMRC compliance guarantees, and ISO-certified data security included. You also avoid the costs of payroll software licences, training, and cover for holidays and sick leave.

The time saving is equally significant. Processing payroll in-house for 50 employees typically takes 15-20 hours per month when you account for data entry, calculations, RTI submissions, pension contributions, payslip distribution, and responding to employee queries. A managed bureau reduces your involvement to submitting employee data changes – typically 1-2 hours per month. That freed-up time can go toward higher-value activities like recruitment, employee engagement, or financial planning. For growing businesses where the office manager or finance director currently handles payroll alongside other responsibilities, outsourcing removes one of their most time-consuming and stressful tasks.

Compliance risk is the hidden cost of in-house payroll. HMRC penalties for late RTI submissions start at £100 per month and escalate based on the number of employees. Pension auto-enrolment errors can trigger fines from The Pensions Regulator ranging from £400 per day for small employers up to £50,000 per day for large organisations. Incorrect tax calculations create year-end headaches and employee dissatisfaction. A managed bureau carries professional indemnity insurance and guarantees compliance – transferring that risk from your business to the provider. If the bureau makes an error, they fix it at their cost. If you make an error using DIY software, the liability is yours.

In-house payroll still makes sense in specific situations: if you have fewer than 10 employees and an accountant or bookkeeper already on staff, the additional workload is manageable. Using affordable software like Sage (from £20/month), Moneysoft, or Xero (£1.50/employee/month add-on) keeps costs minimal while automating the compliance-heavy parts. Some businesses also prefer to keep payroll in-house for confidentiality reasons – sharing salary data with a third party is a concern for some organisations, particularly family-run businesses. But once your headcount crosses 30 employees, or your pay structures become complex (multiple pay frequencies, shift allowances, salary sacrifice schemes), the economics and risk profile strongly favour outsourcing to a specialist bureau.

How We Researched This Guide

We verified all pricing directly from provider websites in February 2026 and assessed each provider across six criteria including cost, compliance, and scalability.

Every pricing figure in this guide was verified directly from provider websites and official pricing pages in February 2026. Where providers do not publish pricing (Moorepay, ADP, Access People), we clearly state that quotes are required and, where available, note industry-typical ranges. We do not fabricate or estimate pricing – if a number appears in this guide, it comes from a verifiable source.

We assessed each provider across six criteria: pricing transparency (published pricing scores higher than quote-based), service type (managed vs software vs EOR – ensuring we cover each model), UK compliance features (HMRC recognition, RTI automation, auto-enrolment handling), scalability (employee range and growth path from startup to enterprise), accreditations (ISO certifications, CIPP membership, Bacs approval, Trustpilot ratings), and customer satisfaction (verified reviews and retention rates where published). Our Editor’s Pick reflects the provider that scores highest across these criteria while delivering genuine value to the widest range of UK businesses.

This guide is updated regularly to reflect pricing changes, new features, and market shifts. The current version reflects the UK outsourced payroll market as of February 2026. Promotional offers (such as Sage’s 90% discount) are verified at the time of writing but may change without notice. If you spot an error or a price change we have missed, please let us know and we will verify and update accordingly.
