Best Cashback Credit Cards UK 2026

Cashback credit cards pay you a percentage of your spending back as cash. Unlike rewards cards that give you points to redeem, cashback is straightforward — you spend, you earn, the cash goes back to your account or reduces your balance.

American Express dominates the UK cashback card market but is not accepted everywhere. For spending at retailers that do not accept Amex, Santander and NatWest offer competitive Visa/Mastercard cashback alternatives.

Card	Cashback Rate	Annual Fee	Network	Best For
American Express Platinum Cashback Everyday	0.5% on first £10,000/year, then 1.0%	None	Amex	Best no-fee cashback card — widely accepted online
American Express Platinum Cashback	1.25% standard rate (0.75% first 3 months)	£25/year	Amex	Best for high spenders — pays for itself at ~£2,500 spend
Santander All in One Credit Card	0.5% on all spending	£3/month (£36/year)	Mastercard	Best Mastercard cashback — also has 0% purchase period
NatWest Reward Credit Card	1% at supermarkets, 0.25% elsewhere	£2/month (£24/year)	Mastercard	Best for supermarket shoppers
John Lewis Partnership Credit Card	Cashback as John Lewis/Waitrose vouchers	None	Mastercard	Best for John Lewis and Waitrose shoppers

Cashback rates correct as of April 2026. Always verify current rates directly with the provider before applying as rates and terms change. Cashback earned is typically paid annually or as statement credit.

American Express Cashback Cards — The Acceptance Issue

American Express offers the highest cashback rates in the UK market but is not accepted by all UK retailers. Major retailers including Costco, Ikea (some locations), and many small businesses do not accept Amex. Before choosing an Amex cashback card, consider where you spend most of your money — if you primarily shop at Amex-accepting retailers and online, the higher earn rate makes Amex the clear winner. If you need universal acceptance, a Mastercard or Visa cashback card is more practical.

Is a Cashback Card Worth It?

A cashback card is worth it if you clear your balance in full every month. If you carry a balance and pay interest, the interest cost will almost always outweigh the cashback earned. The golden rule: only use a cashback card for spending you would do anyway, and always pay the full balance each month.

Annual Spending	Amex Everyday (no fee)	Amex Platinum (£25 fee)	Santander All in One (£36 fee)
£5,000	£27.50	£12.50 (after fee)	£-10.75 (after fee)
£10,000	£55.00	£100.00 (after fee)	£13.50 (after fee)
£15,000	£80.00	£162.50 (after fee)	£38.75 (after fee)
£20,000	£105.00	£225.00 (after fee)	£64.00 (after fee)

Calculations are illustrative based on published cashback rates as of April 2026. Actual cashback earned depends on where you spend and the exact rate applied. Always verify current rates with the provider.

Bottom Line

American Express Platinum Cashback Everyday is the best no-fee cashback card in the UK — earning 0.5% rising to 1% above £10,000 annual spend with no annual fee. For higher spenders (above ~£15,000/year), the Amex Platinum Cashback at £25/year offers better value at 1.25%. If you need a Mastercard that is accepted everywhere, Santander All in One at £3/month offers the simplest cashback structure.

Frequently Asked Questions

What is the best cashback credit card in the UK 2026?

The American Express Platinum Cashback Everyday card is widely regarded as the best no-fee cashback credit card in the UK, earning 0.5% on the first £10,000 of spending and 1% above that with no annual fee. For higher spenders, the Amex Platinum Cashback at £25/year pays 1.25% standard rate.

Do I pay tax on cashback from credit cards?

In most cases, cashback from credit cards is not considered taxable income in the UK — HMRC treats it as a discount on purchases rather than income. However, tax treatment can depend on individual circumstances, particularly for business spending. If in doubt, consult a tax adviser.

Is American Express accepted everywhere in the UK?

No. American Express is not accepted by all UK retailers. Most major UK supermarkets, online retailers, and restaurants accept Amex, but some businesses — particularly smaller retailers and some large chains like Costco — do not. Always check before relying on Amex as your only card.

How does cashback on credit cards work?

Cashback credit cards earn you a percentage of every qualifying purchase back as cash. The cashback is typically paid annually as a statement credit or into your bank account, though some cards offer monthly cashback. You must clear your balance in full each month to benefit — if you carry a balance and pay interest, the interest cost typically outweighs the cashback earned.
