What Is an Unsecured Business Loan?
An unsecured business loan is a fixed-term loan where no asset is pledged as collateral. The lender assesses risk based on business financials, credit history, and trading record rather than security. Most unsecured lenders require a personal guarantee from company directors – meaning if the business defaults, the director is personally liable – but the business’s physical assets are not at direct risk from a charge or seizure.
The key distinction between “unsecured” and “no personal guarantee” is important: most UK unsecured business loans still require a personal guarantee from directors. The lender cannot seize your business assets, but they can pursue you personally for the outstanding balance. A small number of online lenders offer genuinely guarantee-free loans for small amounts, but these are the exception rather than the rule.
Unsecured Business Loan Rates UK 2026
Unsecured business loan rates in the UK range from approximately 8% APR (established businesses with strong credit, borrowing from Funding Circle or a high-street bank) to 60%+ APR (new businesses with impaired credit using fast-access alternative lenders). The rate you receive depends on your credit score, turnover, trading history, loan size, and repayment term. Always compare total cost of borrowing – not just headline APR – as arrangement fees add significantly to the real cost.
| Provider | Loan Range | Typical APR | Min. Trading | Speed |
|---|---|---|---|---|
| Funding Circle | £10K–£500K | From 6.9% APR | 2 years | 1–3 days |
| iwoca | £1K–£500K | ~29–50% APR (representative) | 6 months | 24 hours |
| Capify | £5K–£500K | 47.9–67.89% APR (examples) | 6 months | 24 hours |
| Barclays | £1K–£100K+ | ~7–15% APR | 2 years | 1–4 weeks |
| NatWest | £1K–£50K (SME) | ~8–16% APR | 2 years | 1–4 weeks |
Unsecured Business Loan Eligibility
Most UK unsecured business loan providers require: minimum 6 months trading (12 months for better rates), £50K+ annual turnover, a UK-registered business (limited company, LLP, or sole trader), and a personal guarantee from directors. High-street banks require 2+ years of filed accounts and a clean personal credit history. Online lenders (Funding Circle, iwoca, Capify) have more flexible criteria and accept newer businesses with lower turnover.
A personal guarantee is standard on most UK unsecured business loans above £25K. This means a company director personally guarantees the loan – if the company cannot repay, the lender can pursue the director’s personal assets. Some lenders cap guarantee liability at a percentage of the loan amount; others require a full personal guarantee backed by a director’s personal assets including residential property.
Your personal credit score matters as much as your business credit profile for unsecured lending. A CCJ, IVA, or multiple missed payments in the last 12 months will restrict you to specialist bad-credit lenders at significantly higher rates. If this applies, see our bad credit business loans guide for lenders that specifically accommodate impaired credit history.
How to Apply for an Unsecured Business Loan
Applying for an unsecured business loan typically takes 20–60 minutes online. You’ll need: 3–6 months of bank statements (most lenders accept Open Banking access), Companies House number (if limited company), most recent filed accounts or management accounts, and a summary of what the loan is for. Online lenders typically give a decision within 24–72 hours. Using a broker (Think Business Loans, Swoop) gives access to multiple lenders with a single application and no additional hard credit search.
- Check your credit profiles – personal (Experian, Equifax, TransUnion) and business (Creditsafe, Experian Business) before applying. Errors cost you approvals and rate points.
- Determine your borrowing needs – loan amount, term, and monthly repayment capacity. Lenders use an affordability assessment; if your business has inconsistent cash flow, have an explanation ready.
- Compare lenders directly or use a broker – direct comparison gives you full control; brokers reduce the number of credit searches and often have pre-agreed rates with lenders that aren’t publicly advertised.
- Review the offer in full – APR, total amount repayable, arrangement fee, early repayment penalty, and personal guarantee terms. The cheapest headline rate is not always the cheapest total cost.
- Sign and receive funds – most online lenders transfer funds within 24–48 hours of signing the facility agreement.
Unsecured vs Secured Business Loans
Unsecured loans are faster, simpler, and don’t put specific assets at direct risk – but they cost significantly more. Secured loans offer lower rates and larger amounts but take longer and require a formal asset charge. For amounts under £100K with a 1–5 year term, unsecured is usually the right starting point. For amounts over £250K or terms over 5 years, secured lending is almost always cheaper and should be explored first if you have eligible assets.
