Best High-Risk Merchant Accounts UK 2026: Top Options Compared

BusinessExpert may earn a commission if you sign up through links on this page. Square and Takepayments are affiliate partners. Our editorial recommendations are based on verified pricing and features, not commission rates.

High-risk merchant accounts are needed by businesses in sectors with elevated chargeback rates, regulatory complexity, or card scheme restrictions. This includes adult content, e-cigarettes, supplements, travel agencies, subscription boxes, and some professional services. The key question is whether a PSP like Square or Stripe will accept your sector, or whether you need a specialist acquirer.

High-risk merchant accounts compared

Acceptance criteria and fees verified against provider websites, May 2026. Sector acceptance is at each provider’s discretion.

Best high-risk merchant account picks

Best for instant setup: Square

Square accepts a wide range of businesses that traditional acquirers flag as high-risk: gyms, beauty services, tradespeople, tutoring, professional services, and most retail sectors. Sign-up is instant with no manual underwriting. The 1.75% flat rate applies regardless of card type. Square’s terms of service prohibit certain sectors (adult content, gambling, firearms) — verify your sector is permitted before applying.

Best for e-commerce high-risk: Stripe

Stripe’s automated risk platform (Stripe Radar) screens businesses during onboarding. It accepts many sectors that traditional banks decline, and its API allows businesses to build custom checkout flows with built-in compliance tooling (Stripe Identity for age verification, for example). Stripe explicitly prohibits certain categories — review the restricted business list before integrating.

Best for contract-based high-volume: Takepayments

Takepayments works with businesses in sectors that require manual underwriting — including some that PSPs decline automatically. The 18-month contract and account manager relationship means a human reviews your application. This takes longer but gives you a route to acceptance that automated PSP onboarding may not. Contact Takepayments directly with your sector and volume before starting the application.

What sectors are considered high-risk?

Card schemes and acquirers define high-risk categories based on chargeback history, regulatory complexity, and reputational risk. Common high-risk categories in the UK:

• Travel agencies, tour operators, and accommodation brokers (high advance payment amounts)
• Subscription services (recurring billing, cancellation disputes)
• E-cigarettes and vaping products (regulatory complexity)
• Supplements and nutraceuticals (health claims, chargeback risk)
• Adult content (explicit card scheme restrictions)
• Gambling and gaming (FCA licensing required)
• Debt recovery and credit repair services

Not all high-risk sectors are declined by all providers. Square and Stripe accept many of the above if your business model is compliant and chargeback rates are controlled. Sectors they typically prohibit (gambling, adult content, firearms) require a specialist high-risk acquirer.

High-risk merchant account features

Rolling reserves

Some providers hold a percentage of your card revenue in a rolling reserve to cover future chargebacks. PSPs like Square and Stripe do not routinely apply reserves to new accounts, but may do so if your chargeback rate rises above 1%. Traditional acquirers negotiating high-risk contracts typically require a reserve upfront. Confirm reserve terms in writing before signing.

Chargeback management

Square and Stripe both provide chargeback dispute tools via their dashboards. Stripe Radar offers pre-built fraud rules and custom risk scoring. Worldpay and TakePayments have dedicated chargeback teams as part of their account management service — useful for businesses with complex dispute patterns.

Frequently asked questions

Can I use Square if my business is high-risk?

Square accepts many sectors that traditional acquirers classify as high-risk. Check Square’s prohibited businesses list before applying. Sectors it typically declines include adult content, gambling, and cannabis. Most retail, professional services, and subscription businesses are accepted.

What happens if my account is closed by a PSP?

PSPs can close accounts that breach their terms of service, often with limited notice. If your account is closed mid-business, funds in transit may be held for 90–180 days. For businesses with elevated risk profiles, having a backup payment method (a second PSP or a direct acquiring relationship) reduces the impact of an unexpected closure.

Is a high-risk merchant account more expensive?

Not always, if you use a PSP like Square or Stripe — they charge flat rates with no surcharge for high-risk sectors they accept. Custom acquiring relationships for genuinely high-risk businesses do typically carry higher rates, rolling reserves, and compliance requirements that add to the total cost.
