Mainstream PSPs like Stripe and Square operate as Payment Facilitators: they pool thousands of merchants under a single master account and conduct underwriting after you start processing. High-risk sectors are flagged and terminated algorithmically, often without notice, with funds held for 90 to 180 days. If your sector has been rejected by a PSP or your account has been closed, you need a specialist acquirer from the list below.
Best High-Risk Merchant Accounts for UK Businesses
The providers below serve businesses that mainstream PSPs have declined or are likely to decline. Each covers a different part of the high-risk market.
Most require a pre-application or sales conversation rather than instant self-serve sign-up. We verified sector acceptance, fees, and regulatory status directly from each provider in June 2026.
Best for SMBs declined by mainstream PSPs: NomuPay
NomuPay runs on the infrastructure it inherited from Total Processing, so it comes with an established base of borderline high-risk UK merchants rather than a cold start.
If you are in gaming, travel, forex (MCC 6012), ticketing, technology, e-commerce, or hemp oil and a PSP has already turned you down, this is the first call to make.
The difference that matters: a person underwrites your application, not an algorithm. Your account does not get closed at 9am on a trading day because the system noticed your MCC overnight.
There are no setup fees and no cancellation fees, so the cost of trying is low. Rates are bespoke, which means a quote before you can compare. That is the honest trade-off with every specialist acquirer here: more stability, less pricing transparency than the flat-rate PSPs you have left behind.
One caveat worth checking. NomuPay operates under a Bank of Lithuania payment institution licence, not direct FCA authorisation. If your sector specifically needs UK-regulated acquiring, confirm that licence is enough before you apply.
Visit NomuPayBest for FCA-regulated iGaming and forex operators: ECOMMPAY
ECOMMPAY is London-headquartered and directly authorised by the FCA (reference 607597). It is a Visa and Mastercard Principal Member, so UK card volume is processed through UK acquiring infrastructure rather than routed offshore.
That matters for UKGC-licensed gambling operators, FCA-registered forex platforms, and licensed cryptoasset businesses where UK regulatory alignment is part of your compliance requirement.
We checked processing rates against their published benchmarks: 1.5 to 2.9% blended on EU card volume is the typical range. Rolling reserves run 5 to 10% held for 90 to 180 days, negotiated per merchant.
If your underwriting documentation is not FCA-standard, expect delays. ECOMMPAY does not serve borderline sectors or businesses without an active regulatory licence. Not quick, but stable.
Visit ECOMMPAYBest for CBD, nutraceuticals and supplements: Fibonatix
Fibonatix is the provider to call when your problem is product compliance, not just sector risk. It is an FCA-authorised payment institution (reference 768776), founded in 2013, that routes to acquiring partners.
Its edge is consultative onboarding. For CBD it pre-checks your FSA Novel Food authorisation, and for supplements it reviews your product claims, before submitting you to an acquirer. That pre-assessment is why its approval rates beat a cold application.
Expect 4 to 7% on CBD and nutraceuticals, plus gateway, PCI and chargeback fees, and around 21 days to onboard. Because it is a gateway rather than a direct acquirer, the underlying acquirer sets your rolling reserve.
Visit FibonatixBest for adult, dating and the widest sector reach: Axcess Merchant Services
Axcess is a Leeds-based ISO, trading since 2007, with a network of more than 390 acquiring banks. If you have been declined repeatedly in adult, dating or gaming, that breadth gives you the best odds of finding a bank that will board you.
Rates run 1 to 4.99% depending on whether transactions are swiped, keyed or virtual, and Axcess will argue your rolling reserve down on your behalf rather than just passing on the bank’s opening number.
The trade-off is that you are one step removed. Axcess is an ISO, not a direct acquirer, so the partner bank holds your funds and can change your reserve. Its FCA-regulated claim is not verified on the register; ask for the regulated entity and which bank holds your money before you sign.
Visit AxcessBest for enterprise and high-volume merchants: Worldpay
Worldpay is the established tier-1 option, a Visa and Mastercard principal-member direct acquirer (owned by Global Payments as of early 2026). It holds the risk itself rather than routing you to a third party, which is what buys the stability.
It accepts regulated gambling, travel, subscriptions, forex and adult at scale. The catch is that high-risk pricing is nothing like the 1.5% headline SME rate: expect 3 to 8%, plus a 5 to 15% rolling reserve held 90 to 180 days.
Contracts run 18 to 36 months and onboarding takes weeks to months. It only earns its keep at volume, roughly £75,000 a year minimum, with bespoke structuring from about £400,000 a month. Get the all-in effective rate in writing; the fee stack is layered.
Visit WorldpayBest for cross-border B2B and multi-acquirer routing: Payroc
Payroc operates a multi-acquirer strategy, routing gaming and financial institution transactions across several acquiring banks to achieve a reported 94% approval rate for gaming merchants.
If your business processes substantial card volume and a single acquirer’s downtime or chargeback breach would be costly, that routing redundancy is genuinely useful.
Rates run around 3.9% for high-risk accounts, with a 10% rolling reserve held for 180 days.
Read the reserve clause closely before you sign. Payroc’s terms let it raise that reserve without prior notice if your processing history changes, which means the share of revenue you can actually touch is not fixed at the number you agreed.
Get the cap in writing. This is an enterprise product; under roughly £100,000 a month in card volume, the cost does not earn its keep.
Visit PayrocOther UK high-risk acquirers worth knowing
The six above cover most situations, but the UK high-risk market is wider. Depending on your sector and scale, these are also worth a quote.
Nuvei (FCA reference 994233) is a powerhouse for large, licensed gambling, crypto and forex operators, with enterprise minimums that rule out most smaller merchants.
Trust Payments suits borderline businesses such as travel, ticketing and digital goods that do not cross into adult or gambling. Cashflows (FCA reference 900006) is a UK-native direct acquirer focused on lending and subscriptions with fast settlement.
PayXpert (FCA reference 744033) is the pick if your high-risk angle is heavy cross-border sales into Asia, through WeChat Pay, Alipay and JCB. Confirm each provider’s FCA reference on the register before you commit.
One name to skip for most readers: Acquired.com is FCA-authorised but serves only regulated financial services (lending, debt collection, insurance) and explicitly will not take gaming, adult or supplements. If a PSP dropped you over your sector, it is a dead end.

How to Get a Merchant Account if Your Business Is High-Risk
Getting a high-risk merchant account involves a more thorough application process than signing up with a mainstream PSP. Here is what determines whether you get approved.
Why businesses are flagged as high-risk
Acquiring banks flag businesses when the expected chargeback rate, regulatory complexity, or reputational exposure is above their threshold.
The most common reasons: your sector has a historically high dispute rate (supplements, subscriptions, travel), your business model involves delayed fulfilment (advance booking), you are in a regulated sector (gambling, forex, crypto), or you are new with no processing history.
The Visa VAMP chargeback threshold tightened to 0.9% in January 2026, which has pushed more borderline merchants toward specialist acquirers.
PSP vs dedicated merchant account
Mainstream PSPs like Stripe and Square operate as Payment Facilitators. They pool thousands of merchants under a single master account and underwrite you after you have started taking money.
When their systems later flag a restricted sector or a chargeback spike, they freeze and close the account, often with no notice. Funds held for 90 to 180 days is not a line in the terms you skim past.
It is the money you were counting on for payroll, stock, and the next VAT bill, sitting locked while the account that earned it no longer exists.
A dedicated merchant account from a specialist acquirer works the other way round. The risk is priced in before you process a single transaction, so there is no nasty surprise three weeks in.
And because you have your own merchant ID rather than a slot in a shared pool, another merchant’s bad month cannot take your account down with it.
Rolling reserves
Most specialist high-risk acquirers hold a percentage of your daily card revenue in a rolling reserve as security against future chargebacks. The standard range for new UK high-risk accounts is 5 to 10% held for 90 to 180 days.
Higher-risk sectors such as travel, adult content, and unregulated supplements can attract reserves of 15 to 20%. Reserves are either uncapped (the percentage rolls indefinitely) or capped (once the reserve account reaches a pre-agreed balance, the rest is released).
Confirm which structure applies and negotiate a cap where possible. You can renegotiate a reduction after demonstrating a clean chargeback history over 6 to 12 months.
Chargeback thresholds
Visa’s Acquirer Monitoring Programme sets a 0.9% chargeback ratio as the threshold before placing a merchant in a monitoring programme. Mastercard’s Excessive Chargeback Programme triggers at 1.5%.
Accounts that consistently breach thresholds can be terminated and the merchant placed on the MATCH list, making it difficult to obtain a merchant account elsewhere.
Chargeback prevention tools such as 3D Secure, Verifi, and clear refund policies are part of the application package that specialist acquirers want to see.
Improving your approval odds
Submit a complete documentation package first attempt: certificate of incorporation, three to six months of bank statements, P&L, existing merchant statements showing chargeback history, your AML and KYC policies, and a website with clear terms, support details, and a visible refund policy.
Businesses with a clean processing history and active chargeback mitigation tools are far more likely to be approved, and to negotiate lower rolling reserve terms.
High-Risk Merchant Account Fees and Reserves
High-risk merchant accounts carry more fee categories than standard PSP pricing. The processing rate is only part of the total cost.
Processing rates
Standard PSPs charge flat rates: Square at 1.75% in-person, Stripe at 1.5% plus 20p online. Specialist high-risk acquirers charge higher rates that reflect the actual risk.
ECOMMPAY typically runs at 1.5 to 2.9% blended on EU card volume. Worldpay’s high-risk arm runs 3 to 8%, and Fibonatix charges 4 to 7% on CBD and nutraceuticals. NomuPay and Axcess use bespoke pricing that requires a quote.
Setup and monthly fees
Some specialist acquirers charge a one-time setup fee of £100 to £500 to cover manual underwriting. Monthly minimum fees of £25 to £100 keep the account open and cover ongoing compliance monitoring.
NomuPay waives both. If the provider charges a setup fee, confirm whether it is refunded if your application is declined.
Chargeback fees
Every chargeback you receive costs £25 to £100 in fees, regardless of whether you win the dispute. At a 1% chargeback rate on 1,000 transactions a month, that is 10 chargeback fees on top of processing costs.
Controlling your chargeback rate is not just about keeping your account open; it directly affects your total cost of processing.
Early termination fees
Providers with fixed-term contracts typically charge £200 to £500 if you exit early. NomuPay has no cancellation fee. ECOMMPAY and Payroc use enterprise contracts with custom terms.
Confirm the exit terms before signing, particularly if you are new to high-risk acquiring and unsure whether the provider is the right fit.
Frequently Asked Questions
Why can’t I use Stripe or Square if my business is high-risk?
Stripe and Square are Payment Facilitators: they pool thousands of merchants under a single master merchant account and use automated risk systems to screen accounts after sign-up. When their algorithms detect a restricted MCC, an unusual chargeback pattern, or a sector on their prohibited list, they freeze the account and terminate it, often without prior notice, with funds held for 90 to 180 days. Specialist acquirers like NomuPay and ECOMMPAY underwrite your account before you start processing, price the risk into their rates, and provide long-term stability because they expect your risk profile.
What is a rolling reserve and how long is it held?
A rolling reserve is a percentage of your daily card revenue that the acquirer holds back as security against future chargebacks. The standard range for new UK high-risk accounts is 5 to 10% held for 90 to 180 days. Higher-risk sectors can attract 15 to 20%. Reserves are either uncapped (the percentage rolls indefinitely) or capped (once the reserve account reaches a target balance, 100% of future settlements are released). You can negotiate a reduction after demonstrating a clean chargeback history over 6 to 12 months.
What happens if I end up on the MATCH list?
The MATCH list (Mastercard Member Alert to Control High-Risk Merchants) is a database of merchants whose accounts were terminated for cause: excessive chargebacks, fraud, or breach of network rules. Most acquirers check the MATCH list during underwriting and will decline an application if you appear on it. MATCH list placement lasts five years. If you believe you were placed incorrectly, you can dispute it through the acquirer that added you.
How long does it take to get a high-risk merchant account?
Manual underwriting takes longer than PSP instant sign-up. NomuPay typically takes days rather than weeks. ECOMMPAY takes one to three weeks and requires full AML and KYC documentation to FCA standards. The fastest route to approval is submitting a complete documentation package first attempt: company documents, bank statements, P&L, existing processing history, your compliance policies, and a website with clear terms and a visible refund policy.
Is a high-risk merchant account more expensive than a standard PSP?
Yes, typically. Specialist acquirers charge higher processing rates (1.5 to 3.9% vs 1.4 to 1.75% for mainstream PSPs), plus setup fees of up to £500, monthly minimums of £25 to £100, and chargeback fees of £25 to £100 per dispute. Rolling reserves also reduce your available working capital while funds are held. For genuinely high-risk sectors, this is the cost of operating with a stable, long-term account rather than risking PSP termination and a 90-day funds freeze at a critical moment.
