Editorial standards & research methodology

Who writes and reviews this content

Guides, comparisons and the rates database are written and reviewed by Adam Mable, payments researcher at MerchantSwitch: 15 years in UK merchant acquiring, covering acquirer pricing, interchange and card terminal contracts.

Where our numbers come from

• Published pricing pages of UK payment providers (SumUp, Zettle, Square, Worldpay, Barclaycard, Tyl, Teya and others), checked directly, not copied from other comparison sites.
• Where a provider only offers bespoke pricing (for example Dojo), we say so and give the typical range we see, rather than inventing a single headline rate.
• Worked cost examples state their assumptions (monthly card volume, average transaction) so you can check the arithmetic yourself. See the full UK card machine rates table for our provider-by-provider data.

How often we update

Provider rates and contract terms were last checked in August 2026. Every article carries its real publication and last-updated dates. We never forward-date content to look fresher than it is.

Independence and how we make money

• MerchantSwitch is free for businesses. We may receive a referral fee from a provider when a switch completes.
• No provider pays for placement in our comparisons, tables or verdicts.
• We are an introducer, not a financial adviser, and we are not authorised or regulated by the FCA. Nothing on this site is financial advice.

Corrections

If you spot a rate, fee or fact that is wrong or out of date, email hello@merchantswitch.com with a link to the page. We check corrections against the provider's published pricing and update the page, including its last-updated date.

What we won't do

• No invented reviews, testimonials or star ratings.
• No fabricated customer counts or savings totals.
• No claims we can't back with a source you can check.
