23 verified, tested and working UK 2026 referral codes — get the rewards

£20–£100 mystery (£50 business)

The biggest two-sided upside in UK banking — a mystery £20–£100 you actually keep (even the floor is £20, up to £100), paid in minutes into a fully FSCS-protected account. The one we recommend first.

£20 sign-up bonus

The biggest UK cashback sign-up bonus, on the site that returns 100% of retailer commission. The only drag is the wait: the £20 unlocks after £10 of confirmed cashback.

$20 in deploy credit

Instant $20 of deploy credit — applied the moment you sign up, no card, no expiry — on a developer platform with low UK latency from Amsterdam. The fastest reward we list: nothing to qualify for.

20 bonus class credits

20 bonus class credits on top of the free trial, no card upfront, no obligation. ClassPass has no discount-code box, so this refer-a-friend link is the only real new-member win.

In-app welcome offer for new joiners

As a new Revolut joiner you get a variable in-app welcome offer, not the headline figure you'll see quoted (that goes to the referrer), after a four-step setup. A strong FCA-regulated bank — but a modest, time-limited reward for joining.

£10 to join with the Klarna Card

A real two-sided cash bonus, but the most work in the wallet sector: you must take the Klarna Card and complete three separate £5 purchases. Pick it if you actually want the Card.

£10 after a £5 spend

Low-friction and two-sided: one £5 checkout on an account most people already have. The £10 arrives as store credit for your next purchase, and the campaign runs to 30 June 2026.

£10 of free riding

The most generous e-bike referral in the UK — £10 of free riding — but London-only, and the credit expires in seven days, so claim it when you'll actually ride.

£4 in ride credit

The widest UK coverage of any ride referral — £4 of ride credit across London and a growing list of cities, on a generous 60-day window. Smaller than Forest, but usable in far more places.

£2.50 ride credit to start

The widest reach outside London — Voi runs about two-thirds of England's e-scooter trials. £2.50 to start is modest, but it's the offer that actually works in your town.

A free month of Flow Pro

A full free month of Flow Pro — a genuinely fast AI dictation app — with no card to start and nothing to cancel. The lowest-risk software trial we list.

$10 in calling credit

Fast and low-effort: $10 of calling credit after a $1 purchase, ideal if you regularly call or top up abroad. The credit is in dollars and there is no FCA cover, as it is a telecoms service.

30-day Traincard — 4% off UK rail

An evergreen invite-and-earn from the world's largest travel group: a 30-day rail discount for you. Modest joiner value, but ATOL-backed and dependable.

Up to £15 in Vinted vouchers

Two rewards on two clocks: £5 for three listings in 7 days, £10 for a sale in 30. It is store credit rather than cash, issued in £5 pieces that can only be spent one per order on baskets of £15 or more.

£2.50 off your first eSIM

A small reward, but the cleanest kind: a discount applied at checkout on your first purchase, with no qualifying spend beyond the purchase and nothing to chase. It cannot be combined with any other Airalo promotion.

Free loaf or barista drink

An item rather than a balance — a free loaf or barista drink, redeemed alongside a paid order on your first visit. At its best when a GAIL's already sits on a route you walk.

$15 coupon towards a paid plan

Not a sign-up reward but an upgrade reward: the coupon only exists once you start paying, and only if you do it within three months of joining. Priced in US dollars.

Pay rent by card, including Amex

There is no joining bonus here: the £30 goes to whoever invited you. What a new tenant gets is the service — rent on a card, including Amex — at a certain 1.99% cost per payment.

£10 towards a £50 order

A 20% discount when your basket lands at £50, spread over four interest-free instalments. Size the basket to the threshold and it is the sharpest single-purchase rate we list.

£5 in Rewards, no spend needed

The smallest reward here and the easiest to claim: no purchase required, just a completed sign-up inside 30 days. It is store credit, and it means opening a credit account.

Reward on your Zable card

FCA-regulated credit, unlike the pay-later products here. Zable publishes no fixed referral figure — it varies by account — so check the app. The soft-search eligibility check is the genuinely useful part.

£10 after £5 cashback

The most forgiving cashback joining offer in Britain: £10 for just £5 of confirmed cashback, with no clock running against it. Link-only, so the reward rides on the URL rather than a code, and it pays out from £1.

£3 after £5 cashback

The only cashback here that works at a supermarket till. Buy an in-app gift card for your basket, the cashback lands in seconds, and code JYFRSHU adds £3 once you earn £5 within 30 days. Built for the weekly shop.
