Banking & Current Accounts
Referral and invite codes for UK mobile banks and current accounts. Free cash bonuses for new customers, editorially verified.
Every UK challenger and digital bank runs a refer-a-friend programme. It's the cheapest acquisition channel Monzo, Revolut, Chase, Starling and Kroo have, which is why the bonuses are real cash. The 2026 headline rates are Monzo's mystery £20–£100 personal reward (typically £20) and flat £50 business bonus, plus Revolut's flat £50 referrer bonus paid when a friend completes the four-step verification flow. Every brand listed below is authorised by the Financial Conduct Authority (FCA) and Prudential Regulation Authority (PRA); eligible cash deposits are protected up to £85,000 per person by the Financial Services Compensation Scheme (FSCS). HonestCodes verifies each bonus against the brand's own published terms before listing, and re-checks monthly. After a payment wallet rather than a current account? See the [Payments & Digital Wallets](/categories/payments) category — PayPal and Klarna sit there because EMI-safeguarded e-money carries different protections to FSCS-protected bank deposits.

Common questions about banking referral codes
Which UK current account has the best referral bonus in 2026?
Monzo Business pays £50 to both sides — the highest two-sided cash bonus among UK challenger banks in 2026. For sole traders or limited-company directors that's the strongest reliable option. For personal customers, Monzo personal pays a mystery £20/£50/£100 to both sides (typically £20, up to £100), while Revolut's flat £50 goes only to the referrer — guaranteed, but one-sided.
Are UK bank referral bonuses taxable?
Cash incentives paid for opening an account are typically classified as miscellaneous income by HMRC. Most UK customers fall within the £1,000 trading allowance and have nothing to declare, but if you stack many referral bonuses across a tax year, check with HMRC or an accountant.
Do bank referral codes expire?
Yes — programmes change. Monzo and Revolut have both restructured their bonus mechanic within the last 18 months. HonestCodes re-verifies each bank's programme monthly and shows the date on every brand page.
Can I open multiple UK bank accounts to claim multiple bonuses?
Yes — there is no UK rule against holding accounts at Monzo, Revolut, Starling, Chase and Kroo simultaneously. You can claim each brand's new-customer bonus once. Each brand's anti-fraud system blocks claiming the same brand's bonus twice (even on different emails or phone numbers).
