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 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 £120,000. 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 receive several in one 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.
