Payments & Digital Wallets
Referral codes for UK-supported payment apps, digital wallets, BNPL services and payment cards — PayPal, Klarna and similar fintech brands.
Payment apps and digital wallets sit between everyday spending and traditional banking. PayPal handles online checkout for hundreds of millions of consumers worldwide; Klarna led the BNPL category and now issues a Visa-rails debit card. Both run live UK refer-a-friend programmes — PayPal pays £10 each side when a friend signs up and spends £5 within 30 days (the Feb–Jun 2026 campaign), Klarna pays £40 to the referrer and £10 to the new customer who signs up for the Klarna Card and shops three times. Both brands are FCA-authorised in the UK; both reward you with credit that lives inside their app rather than as cash to a UK bank account — they are e-money institutions rather than deposit-taking banks, so FSCS protection doesn't apply (funds are safeguarded under the Electronic Money Regulations 2011 instead). If you're after an FSCS-protected current account, see the [Banking & Current Accounts](/categories/banking) category. HonestCodes verifies each programme against the brand's own terms page and re-checks monthly.

Common questions about payments referral codes
What's the difference between a payment app and a current account?
A payment app like PayPal or Klarna holds e-money inside its own system and is regulated by the FCA as an e-money institution (EMI). Your balance is not FSCS-protected — instead the firm is required to safeguard your money in segregated accounts. A current account at Monzo or Revolut Bank UK Branch holds real bank deposits and is FSCS-protected up to £85,000. Use payment apps for everyday spending; use current accounts for salary and direct debits.
Are Klarna and PayPal referral rewards taxable in the UK?
App credit awarded for completing a refer-a-friend programme is typically treated as miscellaneous income by HMRC. Most UK customers fall within the £1,000 trading allowance and have nothing to declare; if you stack many referrals across a tax year, check with HMRC or an accountant.
Does Klarna BNPL affect my UK credit score?
Yes. Since June 2023 Klarna has reported BNPL Pay in 3 and Pay in 30 repayment behaviour to all three UK credit reference agencies (Experian, Equifax, TransUnion). On-time repayments build a positive history; missed repayments mark your file. From 15 July 2026 BNPL Deferred Payment Credit comes fully under FCA regulation, so lender disclosure standards will tighten.
Can I use PayPal and Klarna together at checkout?
At most UK retailers you choose one or the other at checkout — PayPal Wallet or Klarna BNPL/Klarna Card. You cannot stack them on a single purchase. Where Klarna Pay in 3 is supported you can sometimes pay the first instalment using a PayPal balance funding source, but the Klarna agreement is the regulated credit product.
