Best Crypto and Fiat Payment Gateway in the United Kingdom – Accept GBP and Crypto with Regulated Solutions

If your business is based in the UK and you are considering offering British pounds (GBP) for receiving payments from locals along with tapping crypto-friendly customers, there's a lot to cover.

A good fiat payment gateway in the UK will take care of your GBP rails, while a strong crypto payment gateway in the UK will let you handle digital assets or stablecoins and convert or settle them properly. But one that supports both fiat & crypto will let you unlock wider global opportunities, without the need for two setups.

In this blog, we will discuss how gateways work in the United Kingdom, the best ones, current regulatory landscape, and much more.

Understanding payment gateways from a United Kingdom perspective

Let’s break it down.

A fiat payment gateway in the UK means a platform that allows your customers to pay you in GBP via cards, bank transfers, and other local payment methods, and then get the funds into your business account.
A crypto payment gateway in the UK means a platform that supports payments in crypto or stablecoins, with options to convert into fiat (GBP) or another currency, and settle into your account securely.

When you run a global business with a presence in the UK and beyond, you want both crypto-and-fiat integrations so you can reach the local as well as international customers paying in crypto.

How can UK businesses benefit from crypto payment solutions

Here’s why adding crypto payments along with GBP makes sense for UK-based businesses:

It lets you tap into 560M+ cryptocurrency users worldwide (2024 data), giving you broader reach.
Many shoppers drop off because their preferred payment method isn’t available, their card fails, or cross-border payments take too long. Integrating crypto payment solutions helps you boost your sales and reduce card abandonments.
It helps in increasing your basket size since crypto users tend to spend more per transaction.
Crypto rails have the potential to simplify certain cross-border flows: reducing FX friction, providing potentially faster settlement, and offering more optionality in how you hold or convert payments.

Things to look out for while choosing a Web3 payment gateway in the UK

When you evaluate gateways, especially in the UK, here are the questions you must ask yourself:

Does the gateway support GBP, local UK payment methods, and settlement into your business account in GBP?
Does it support major stablecoins or tokens, allow conversion to GBP or another fiat, and let you receive as well as manage crypto payments?
Is the gateway aware of the UK’s regulatory regime?
Does the gateway have strong controls and risk measures in place?
If you run an online store, how easy is it to plug in? Does the gateway support customization?
When you convert crypto into GBP (or choose to hold crypto), what are the fees, and what is the FX risk involved?

How to accept GBP and crypto securely in the UK via TransFi

Here is a step-by-step guide:

Sign up with TransFi Checkout.
Integrate the checkout into your site/app (via plugin or API). Enable GBP payment methods for locals and crypto payment options for global as well as crypto-ative customers.
A UK customer pays in GBP: they see the GBP checkout, pay via local payment method, and you receive the settlement in GBP into your account.
A crypto-paying customer selects crypto payment: the gateway processes the crypto, converts to your preferred fiat (GBP) or leaves it in crypto if you prefer, then settles into your designated account.
On your dashboard you monitor payment inflows.
Through it all, TransFi keeps records of crypto flows, conversions, and ensures you comply with CTF/AML standards.

With TransFi Checkout, whether your customer uses GBP or crypto, you can accept them under one unified checkout, get settlement in the currency you choose, and maintain regulatory clarity.

The current regulatory landscape

The FCA regulates cryptoasset businesses under the AML/CTF regime. If you provide certain crypto-asset services in the UK you must register with the FCA.
Cryptoasset firms in the UK must comply with the ‘Travel Rule’, i.e. they must collect and share information about cryptoasset transfers.
The UK government has published draft legislation to bring activities involving “qualifying cryptoassets” and “qualifying stablecoins” into regulated activities under the HM Treasury and the Financial Services and Markets Act.

If you want to accept crypto payments (especially from UK customers), you need to use a gateway that supports compliant flows. Picking a regulated payment gateway in the UK such as TransFi ensures your business doesn’t remain exposed to any kind of risk.

Future outlook

Here’s where things seem headed in the UK:

The regulation around crypto assets will tighten, bringing more clarity for crypto firms and gateways.
More UK businesses will adopt hybrid payment strategies to unlock wider reach, bypass payment friction, and reduce cart abandonments.
Trust and adoption will improve. As the regulatory framework solidifies, more buyers and sellers will become comfortable with crypto payments.
