Getting a merchant account when your business is classified as “high risk” means higher fees, longer applications, and the constant threat of account freezes. But with the right approach, you can find a reliable payment processor and keep costs manageable.

This guide explains what makes a business high-risk, how pricing works, and the practical steps UK businesses can take to secure a merchant account and reduce their risk profile over time.
High-risk pricing reflects the increased financial exposure the processor takes on. Here’s what each fee covers:
- Transaction fees (3%-10%): The percentage taken from each card payment. Rates depend on your industry, chargeback history, and monthly volume. CBD businesses might pay 4%-6%, while adult content businesses could face 8%-10%.
- Monthly fees (£25-£100): Account maintenance, gateway access, and monitoring charges.
- Setup/application fees (£200-£500): One-off charge covering underwriting and risk assessment. Some providers waive this.
- Rolling reserve (5%-15%): The processor withholds a percentage of each transaction in a reserve account for 6-12 months. This protects them against chargebacks. You get the money back after the holding period.
- Chargeback fees (£20-£50 per dispute): Higher than standard accounts (£15-£25). Some providers charge £100+ for chargebacks that aren’t resolved in your favour.
- Gateway fees: £15-£30/month if using an online payment gateway.
- PCI compliance fee: £50-£100/year (higher than standard £30-£60).
- Always calculate your total monthly cost — not just the transaction rate
- A provider offering 4% with no reserve may — cost less overall than one offering 3% with a 10% rolling reserve
- especially for cash-flow-sensitive — businesses

How to Get a High-Risk Merchant Account in the UK
To get a high-risk merchant account, prepare 3-6 months of processing history, a fraud prevention plan, and apply to specialist providers like Worldpay, PaySafe, or Cardstream rather than mainstream PSPs.
The application process for a high-risk merchant account is more involved than a standard account. Expect 5-15 business days for approval (versus instant with Square or SumUp), and be ready to provide detailed documentation.
Step 1: Prepare your documentation
- Company registration documents (Companies House certificate)
- Proof of business address (utility bill or bank statement)
- Directors’ personal ID (passport or driving licence)
- 3-6 months of business bank statements
- 3-6 months of processing statements (if you have an existing merchant account)
- Company financial statements or management accounts
- Website URL (must be live, with clear terms and conditions, privacy policy, and refund policy)
Step 2: Create a chargeback prevention plan
Underwriters want to see that you take fraud prevention seriously. Prepare a document covering:
- How you verify customer identity (3D Secure, address verification, CVV checks)
- Your refund and cancellation policy (clear, accessible, generous policies reduce chargebacks)
- Customer service procedures (easy-to-reach support reduces “where’s my order” chargebacks)
- Delivery tracking and confirmation processes
- How you handle recurring billing (clear consent, easy cancellation, pre-billing notifications)
Step 3: Apply to the right providers
Do not apply to mainstream providers like Square, SumUp, or standard PayPal — they will either reject you outright or accept you and then freeze your account when they flag your transactions. Instead, approach:
- Specialist high-risk acquirers: Providers that specifically advertise high-risk acceptance (Durango Merchant Services, Instabill, PayKickstart)
- Traditional acquirers with high-risk divisions: Worldpay, Elavon, and Barclaycard all have specialist underwriting teams for higher-risk industries
- UK payment facilitators for moderate risk: Stripe and Adyen accept some borderline industries that Square and SumUp reject — but not the highest-risk categories
Step 4: Negotiate terms
High-risk pricing is always negotiable. Get quotes from at least 3 providers and use them as leverage. Focus on:
- Transaction rate (aim for the lower end of their quoted range)
- Rolling reserve percentage and release timeline (push for 6 months rather than 12)
- Contract length (avoid anything over 24 months)
- Volume-based rate reductions (built-in decreases as your processing history improves)
Apply to 3-5 providers simultaneously. High-risk approval rates vary widely — one provider might reject you while another offers competitive terms. Having multiple quotes also gives you negotiating leverage.
5 Ways to Reduce Chargebacks and Lower Your Risk Profile
Reduce chargebacks by implementing 3D Secure authentication, using clear billing descriptors, offering proactive refunds, providing excellent customer service, and monitoring transactions for fraud patterns.
Your chargeback rate directly determines your risk classification and pricing. Reducing chargebacks below 0.65% (Visa’s “standard” threshold) can qualify you for better rates, and getting below 1% keeps you out of card scheme monitoring programmes.
1. Implement 3D Secure 2.0 (Strong Customer Authentication)
3D Secure (3DS) adds an authentication step to online card payments, shifting liability for fraudulent transactions from you to the card issuer. Since September 2019, Strong Customer Authentication (SCA) is mandatory in the UK for most online transactions under PSD2 regulations. Make sure your payment gateway supports 3DS 2.0 — the newer version that uses biometrics and device data for a smoother customer experience.
2. Use clear billing descriptors
Many “friendly fraud” chargebacks happen because customers don’t recognise the charge on their bank statement. Set your billing descriptor to your trading name (not your registered company name) and include a phone number or URL. For example: “ACMESHOP.CO.UK 0800-123-456” is far better than “ACM TRADING LTD”.
3. Offer proactive refunds over chargebacks
A refund costs you the transaction amount but no chargeback fee. A chargeback costs you the transaction amount PLUS a £20-£50 fee, harms your chargeback ratio, and risks your merchant account. Make it easier for customers to request a refund from you directly than to dispute with their bank. Prominent contact details, a clear refund policy, and a simple refund process all help.
4. Monitor transactions in real-time
Set up alerts for unusual patterns: multiple transactions from the same card in a short period, transactions from unusual locations, orders significantly above your average transaction value. Most payment gateways offer built-in fraud rules — configure them rather than leaving default settings.
5. Document everything
When chargebacks do occur, your ability to fight them depends on documentation. Keep records of: customer communications (especially consent for recurring billing), delivery tracking and proof of delivery, signed contracts or terms acceptance, IP addresses and device data for online transactions, and any correspondence where the customer confirmed satisfaction.
What to Do If Your Merchant Account Gets Frozen
If your merchant account is frozen, contact your provider immediately, provide all requested documentation within 24 hours, and have a backup payment method ready to avoid losing sales.
Account freezes are the biggest risk for high-risk businesses using mainstream providers. If it happens:
- Act immediately: Contact your provider’s risk department within hours, not days. Delays are interpreted as evasion.
- Provide documentation fast: Whatever they request — invoices, proof of delivery, customer communications — send within 24 hours.
- Have a backup: Maintain a second merchant account with a different provider so you can continue accepting payments.
- Know your rights: In the UK, providers must give you reasonable notice before terminating your account (typically 30-90 days). Frozen funds must be released once the investigation concludes, though this can take weeks.
- Switch proactively: If you’re on a mainstream provider (Square, PayPal) and your business is genuinely high-risk, don’t wait for a freeze. Apply for a specialist high-risk account now while your current account is still active.
