A payment facilitator, often called a PayFac, lets UK businesses accept card and digital wallet payments without opening a traditional merchant account. Under this model, the facilitator holds the master merchant relationship with an acquiring bank and onboards smaller businesses as sub-merchants. For women running UK start-ups, e-commerce shops, or service businesses, a payment facilitator can remove much of the administrative burden and upfront cost of taking payments.
What a Payment Facilitator Does
A payment facilitator acts as an intermediary between your business and the payment processor or acquiring bank. Instead of applying for your own merchant account, you join the facilitator’s master account as a sub-merchant. The facilitator manages transaction processing, fraud monitoring, chargebacks, and settlement on your behalf.
This structure differs from a traditional independent sales organisation or merchant account provider. With a merchant account, you negotiate directly with the bank, submit detailed financial records, and wait for underwriting. A payment facilitator bundles these services and uses its own risk controls to approve sub-merchants quickly. Common use cases include software platforms that want to offer embedded payments, marketplaces that need to split payments between sellers, and service businesses that want to invoice by card without a lengthy application.
How Payment Facilitators Are Regulated in the UK
Payment facilitation in the UK sits within the Payment Services Regulations 2017. Any firm that provides payment services, including merchant acquiring and payment processing, must be authorised or registered with the Financial Conduct Authority (FCA). You can check a provider’s status on the FCA’s Financial Services Register.
The regulations set out two main registration routes. An Authorised Payment Institution can handle larger payment volumes. Since Brexit, UK firms no longer benefit from automatic passporting into the European Economic Area, though some may operate through local subsidiaries or national authorisations. A Small Payment Institution handles a monthly average of no more than €3 million in payment transactions and cannot provide payment services outside the UK. Most payment facilitators serving UK small businesses operate as authorised institutions.
The UK contactless card limit has stood at £100 since October 2021, following confirmation by HM Treasury and UK Finance. Payment facilitators typically build this limit into their card readers and payment terminals automatically, along with Strong Customer Authentication rules, enforced from 14 March 2022, that require two-factor verification for many online transactions.
Faster Onboarding for UK Small Businesses
Traditional merchant accounts can take days or weeks to set up. The bank reviews company accounts, credit history, trading history, and projected turnover. New businesses and sole traders often struggle to meet these requirements.
A payment facilitator uses automated underwriting and pooled risk models. Many UK businesses can start accepting payments within hours of signing up. This speed matters if you are starting a business, launching a new product, testing a market, or running a time-limited campaign.
The trade-off is less control over settlement times and reserve policies. A facilitator may hold a rolling reserve to cover chargeback risk, particularly for higher-risk sectors. Read the terms carefully before you commit, and always verify the provider on the FCA register before you hand over business or customer data.
Cost and Cash Flow Advantages
Payment facilitators usually charge a flat per-transaction fee or a simple percentage of turnover. This can be easier to forecast than the tiered rates, monthly minimums, and terminal rental fees common with traditional merchant accounts.
For micro-businesses and side hustles, this transparency helps with cash flow planning. You avoid long-term contracts and can often scale down as easily as scaling up. Some UK facilitators also offer next-day settlement, although standard settlement is typically two to three working days.
Before signing, compare the total cost of acceptance. Look at the transaction fee, any monthly platform fee, chargeback fees, refund fees, and the cost of accepting premium payment methods such as American Express or corporate cards.
Security, Compliance and Customer Trust
Payment facilitators invest in fraud detection, encryption, and tokenisation across their entire merchant base. Because they see transaction patterns from thousands of businesses, they can spot suspicious activity faster than a single small business could.
They also handle much of the Payment Card Industry Data Security Standard (PCI DSS) burden. As a sub-merchant, you still need to follow basic security practices, such as never storing card security codes and using secure checkout pages. However, the facilitator usually manages the most complex compliance requirements.
Under UK law, payment service providers must also comply with Strong Customer Authentication for electronic payments. This means customers may need to confirm online purchases through a banking app, text message, or card reader. A reputable payment facilitator builds these checks into the checkout flow without adding unnecessary friction.
Choosing a Payment Facilitator for Your Business
Start by checking the FCA register to confirm the provider is authorised or registered. Then compare the following points:
- Transaction fees and monthly charges
- Settlement speed and reserve policies
- Supported payment methods, including Apple Pay, Google Pay, and buy-now-pay-later options
- Integration with your e-commerce platform, accounting software, or booking system
- Customer support hours and dispute handling
Consider your sales channels too. If you sell in person, you need a facilitator that offers card readers or tap-to-phone technology. If you sell online, look for hosted checkout pages and APIs that work with your website builder. Also think about growth. A facilitator that works well at £5,000 a month in turnover may become expensive at £50,000 a month. At that point, a dedicated merchant account with interchange-plus pricing may save money, even though it requires more paperwork.

The payment facilitator model offers a practical route into card acceptance for UK small businesses that want speed, simplicity, and predictable costs. It is not the right choice for every business, particularly those with high transaction volumes or complex risk profiles. For many women-led start-ups and growing enterprises, however, it removes a significant barrier to trading and lets you focus on customers rather than payment infrastructure.
