UK businesses accepting card payments can choose between traditional merchant service providers, pay-as-you-go platforms and full-service payment providers, each with different fee structures and contract lengths. We review providers independently and never sell your data, so you can shortlist by transaction volume and business type rather than sales pitches.
Compare the best payment providers in the UK for retail, ecommerce, hospitality and growing businesses. We review transaction fees, contract terms and settlement speed so you can choose the right provider and reduce processing costs.

Alternative payment methods
It depends on your transaction volume, average sale value and whether you take payments in person, online or both. High-volume businesses usually get better rates with interchange-plus providers like Stripe or Worldpay, while low-volume or seasonal businesses often do better with pay-as-you-go providers like SumUp or Square that charge no monthly fee. Compare the table above by your business type for a shortlist.
The terms are used interchangeably in the UK. A merchant service provider (or payment provider) supplies the account, hardware and processing needed to accept card payments. Some are full-service (merchant account plus gateway plus hardware); others specialise in one part, such as just the card machine or just the gateway.
Most UK payment providers charge a per-transaction fee (typically 0.3% to 2.9% depending on card type and pricing model), and some add a monthly account fee or hardware rental cost. Interchange-plus pricing is usually cheaper for businesses processing more than a few thousand pounds a month; flat-rate pricing suits lower, less predictable volumes.
It depends on your existing contract. Rolling monthly contracts can usually be cancelled with 30 days’ notice, but many providers still lock businesses into 12-18 month minimum terms with exit fees if you leave early. Check your current terms before switching.
No. Pay-as-you-go providers like SumUp, Square and Zettle have no monthly fee and no minimum contract, though their per-transaction rates are usually higher. Traditional merchant account providers typically require a 12-18 month contract in exchange for lower per-transaction rates.
Compare total cost, not just the headline rate: per-transaction fee, monthly account fee, hardware cost, contract length and settlement speed together determine what you actually pay. Use your average monthly card takings and typical transaction size to estimate real monthly cost for each provider before deciding.
Yes — most full-service providers (Worldpay, Adyen, Paymentsense) offer a card machine, an online checkout and a virtual terminal for phone/mail-order payments under one account, usually with a single monthly statement. Pay-as-you-go providers like SumUp and Square cover in-person and online but rarely phone payments without an add-on. Check our card machine comparison and online payment systems comparison if you need more than one channel.
A virtual terminal is a secure web page that lets staff key in card details manually to take a payment over the phone or by mail order, without a physical card machine. You need one if you take telephone or postal orders regularly — most merchant account providers include it free or for a small monthly add-on, while pay-as-you-go providers often charge a higher per-transaction rate for keyed-in payments due to higher fraud risk.
Yes, but not through mainstream providers in most cases. Sectors classed as high-risk — gambling, adult content, travel, CBD, forex, debt collection — are usually declined by SumUp, Square, Stripe and similar low-risk-focused providers, and need a specialist high-risk merchant account instead. These typically carry higher transaction fees (often 2-4%) and rolling reserves, but give access to card acceptance that would otherwise be refused. See our high-risk sector guide for specialist providers.
Pay-as-you-go providers like SumUp, Square and Zettle can be approved and taking payments the same day, since there is no underwriting beyond a basic identity check. Traditional merchant accounts typically take 3-10 working days, as the acquiring bank underwrites your business, trading history and risk profile before approval. High-risk merchant accounts can take 2-4 weeks due to additional compliance checks.
Providers can freeze or hold funds if they flag unusual transaction patterns, chargeback spikes, or suspected fraud — this is more common with pay-as-you-go providers like PayPal and Stripe, which use automated risk algorithms with limited human review. Funds are usually released after 90-180 days if no issue is confirmed, but this can seriously disrupt cash flow. Keeping a backup merchant account with a different provider is a sensible safeguard if your business relies on a single processor.
Yes, almost universally. UK and European personal debit/credit cards get the lowest rates, while non-European cards (US, Asia, Middle East) typically cost an extra 0.5-1.5 percentage points due to higher interchange fees set by the card schemes. If a meaningful share of your customers pay with non-UK cards, compare providers on their specific non-UK card rate rather than the headline UK rate alone.
