Curve Referral Code
Join Curve through an invite and you earn 1% cashback on everything you spend on your Curve card for 30 days, capped at £15 each in the UK and the same figure in euros in the EEA. It unlocks only after five purchases of at least £2 each, and it arrives as Curve Cash Points, which you can spend through Curve but cannot withdraw as cash.
This program uses referral links rather than codes - the button below is the referral itself and applies the bonus automatically. Completely free, no payment or paywall.
If you sign up through this page, this site may receive the referrer's side of the reward. This never costs you anything extra.
Requirements to qualify
- You sign up to Curve as a new customer via a referral invite.
- You complete at least 5 purchases of £2+ with your Curve card.
- Both sides then get 1% back on their own spending for 30 days, capped at £15 each. It is paid as Curve Cash Points, which you can spend through Curve but cannot withdraw, and reaching the £15 cap takes £1,500 of spending inside those 30 days.
What the invite actually pays you, and what it does not
The reward is a rate, not a lump sum, so what you collect depends on how much you spend in the month after you qualify. Curve's help article, last updated 24 October 2025, sets the ceiling at £15 each for UK customers and the same number in euros for EEA customers. Since the rate is a penny in the pound, that ceiling only binds once around £1,500 of qualifying spending has gone through the card inside the window. That figure is arithmetic rather than something Curve publishes, but it is the one that matters: on £400 of monthly spending the realistic reward is nearer £4.
What arrives is also not money in the ordinary sense. Curve's Referral Offer Terms, version 3, published 6 July 2026, credit the reward as Curve Cash Points on your Curve Cash Card, state that those points have no cash value, that they are not e-money, and that you cannot withdraw or redeem them for cash. You spend them by selecting the Curve Cash Card as your payment source. There is no transfer to your bank account at any stage.
The same terms exclude a long list of spending from earning anything, covering most of what someone would reach for to hit the ceiling fast.
- Anything financial: wire transfers, money orders, insurance premiums, cash disbursement, quasi cash, stored value funding, securities and shares, bonds.
- Gambling, lotteries and casinos, plus fines, bail and bond payments, tax payments and government services.
- Curve Fronted transactions, which is how you would pay HMRC with a credit card through Curve.
- ATM withdrawals, and anything bought using your existing Curve Cash balance.
- Colleges, universities and professional schools.
Who Curve is, and where your money actually sits
Curve is not a bank account and does not try to be one. It issues a Mastercard that sits on top of the debit and credit cards you already hold, and charges whichever underlying card is selected in the app. Your salary stays where it is. The draws are switching which card paid for a purchase after the fact, and routing foreign spending through Curve's rate rather than your bank's.
The legal answer differs by region, and the two entities are separate companies. In the United Kingdom your contract is with Curve UK Limited, company number 09523903, registered at 1-10 Praed Mews, Tyburnia, London W2 1QY and authorised by the Financial Conduct Authority to issue electronic money under firm reference number 900926. In the EEA your contract is with Curve Europe UAB, a Lithuanian company registered under number 305626541 in Vilnius, holding electronic money institution licence No. 73, issued by the Bank of Lithuania on 22 October 2020 and supervised by it. Both sets of terms are at version 6, published 17 November 2025.
For most of what Curve does, neither entity holds your money at all, because funds move from your underlying card to the merchant. The exception is the Curve Cash Card, which carries an e-money balance. That distinction decides the protection question below.
The real cost: four plans, a weekend surcharge and ATM caps
Curve renamed its tiers in 2026. As listed on its subscription help article on 17 February 2026, the free plan is Curve Pay, formerly Curve Lite. Curve Pay X, formerly Curve X, is £5.99 a month. Curve Pay Pro, formerly Curve Black, is £9.99 a month or £99.90 a year. Curve Pay Pro+, formerly Curve Metal, is £17.99 a month or £179.90 a year. Those are UK prices; EEA customers are billed in euros at figures Curve shows only in the app.
Foreign spending is where the free plan hurts. Curve's fees article, last updated 24 May 2026, gives each plan a fee-free foreign exchange allowance per calendar month: £250 on Curve Pay, £3,333 on Curve Pay X, £50,000 on Pro and £100,000 on Pro+, with the same numbers in euros for EEA customers. Past your allowance, Curve adds 2.99% to the Mastercard wholesale rate on the free plan, or 1% on every paid plan.
The surcharge that catches people is the weekend fee. On the free plan only, Curve adds a further 1.5% on top of the wholesale rate and any other fee, running from Friday 23:59 UTC to Sunday 23:59 UTC. Every paid tier removes it. Holiday spending is disproportionately weekend spending, so a free-plan user abroad on a Saturday with the allowance gone pays 2.99% and 1.5% on the same transaction.
Cash is the other trap. The free plan has no fee-free ATM allowance at all: Curve charges the greater of 2% of the withdrawal or £2 from the first withdrawal onwards. Paid plans give a monthly allowance before the same charge applies, £300 on Curve Pay X, £500 on Pro and £1,000 on Pro+. Your own issuer may add a cash advance charge on top, since Curve passes the merchant category code through.
- Paying government agencies such as HMRC with a linked credit card through Curve Fronted costs 2.5% of the transaction, after a fee-free monthly allowance of £1,000 on Pro and £3,000 on Pro+.
- Funding a payment with a card issued outside the UK and EEA costs 2.9% per transaction, with no free allowance on Curve Pay or Curve Pay X, and using a commercial card on a personal account costs 1.5%.
- Curve adds a service fee in merchant categories it treats as high risk, mostly gambling, dating services and dealers in precious stones.
- Fee windows are measured in UTC rather than local time, so a Sunday evening purchase in Australia can still fall inside the weekend fee period.
Claiming it, and telling whether it worked
There is no code to type anywhere in Curve's signup. The offer travels through an invite link generated in the Invite and earn applet, and you claim it by signing up as a new customer through that link, then completing at least five purchases of at least £2 each on your Curve card. Ordering a card or subscribing to a paid tier triggers nothing by itself.
Curve shows the reward as Pending in your Curve Wallet until every step is done, and tracks status in the Launchpad section of the app. If it has not moved after your fifth qualifying purchase, check the exclusion list first. The offer period runs to 31 December 2026 under the version 3 terms, is open to new customers aged 18 or over resident in the UK or EEA, and Curve can end it without notice or reverse a reward it believes breached its Fair Use Policy. The person who invited you earns on the same terms.
Safeguarding is not deposit insurance, and Curve says so itself
Neither Curve entity is a bank and neither takes deposits. Curve UK Limited is an electronic money institution, and its own UK terms state that the Financial Services Compensation Scheme does not apply to e-money or to funds used to purchase e-money. There is no £85,000 guarantee behind a Curve balance.
What you get instead is safeguarding: Curve must keep customer funds in an account separate from its own so they can be returned if it stops operating. Curve's UK terms are unusually candid about the limit. They state that in an insolvency the funds returned to you may be less than the total in your account, because the costs of arranging repayment and the costs of the administrators coordinating the return of customer money may be deducted from what you are owed. A deposit guarantee pays out in full to the limit on a fixed timetable. Safeguarding pays out whatever survives the administration, whenever it finishes.
The EEA position is the same and stated more bluntly. The Curve Europe UAB terms say Curve is not allowed to pay interest on funds it holds for you, that they are not protected by the Deposit Insurance Fund, the Lithuanian deposit guarantee scheme, and that Curve keeps them in a safeguarding bank account instead. An EEA balance carries no €100,000 guarantee, and the referral terms add that FSCS protection does not apply to the Curve Cash Card either. The practical exposure is modest, since Curve rarely holds much of your money for long, but Curve and a challenger bank are not comparable on safety and Curve does not pretend otherwise.
Who Curve suits, and who should walk away
Curve is genuinely good at something nothing else does as cleanly: retroactively changing which card paid for a purchase. Go Back in Time reaches 60 days on Curve Pay X, 90 on Pro and 120 on Pro+, which earns its keep if you regularly realise afterwards that a purchase should have gone on a business card or one carrying an interest-free balance. Collapsing a dozen cards into one piece of plastic and one transaction feed is a real convenience.
The case against is that Curve adds a layer of fees and a layer of risk to cards that already work. If you spend abroad more than occasionally, the free plan is not the cheap option it looks: £250 of foreign spending a month is one long weekend, and beyond it you pay more than a decent travel card charges. Revolut and Wise both give a larger free allowance and a cleaner rate, and Wise publishes its margin per currency up front. Neither, though, lets you push the payment onto your own credit card.
Sign up if you carry several cards, want only one of them in your wallet, and value moving a transaction between them after the event. Look elsewhere if what you want is cheap foreign spending, where a dedicated travel card wins, or if you want money sitting somewhere covered by a deposit guarantee, where you want a bank.
Curve breaks Section 75 on your credit card and replaces it with its own discretion
This has no equivalent at any other card in this category, and it is the reason to think hard before making Curve your default. Section 75 of the Consumer Credit Act 1974 makes a UK credit card provider jointly liable with the retailer for purchases between £100 and £30,000. It is why people put holiday, kitchen and building deposits on a credit card.
Curve's own UK terms confirm that routing the payment through Curve breaks that chain. Where the Curve Card acts as a debit card funded by a linked credit card, you are not covered by Section 75, because the purchase is not a direct purchase from the underlying credit card. Your issuer sees a payment to Curve, not to the merchant, so the joint liability never attaches. The protection does not weaken. It disappears.
In its place Curve offers Curve Customer Protection, a policy rather than a statutory right. It covers goods and services not received, defective or counterfeit goods, refunds a merchant failed to make and duplicate charges, up to £100,000 per dispute, claimed within 120 days of the purchase, receipt of goods or the event. Curve's own wording is that claims are refunded at Curve's discretion, that it is not a warranty, and that Curve provides no guarantees. That is materially weaker than a statutory claim you can escalate to the Financial Ombudsman Service.
The rule that follows is simple. For everyday spending, routing through Curve costs you nothing you will miss. For anything where you would want Section 75 behind you, a flight, a holiday deposit, furniture, a tradesman, put it straight on the credit card.
Curve referral code FAQ
Is there a Curve code to enter at signup?
No. The joining offer travels through an invite link generated in the Invite and earn applet, and no code field appears during signup. Curve does separately run partner promo codes, entered at account creation and working differently, so do not confuse the two.
How much do I actually have to spend to get the full reward?
Five purchases of at least £2 each unlock the offer, but that only starts the cashback. At a penny in the pound against a fifteen-unit ceiling, reaching the maximum takes roughly £1,500 of qualifying spending inside the window, and ATM withdrawals, tax payments and the other excluded categories do not count toward it.
Is my money safe with Curve?
It is safeguarded, not insured. Curve is an electronic money institution in both the UK and the EEA, so the FSCS and the Lithuanian Deposit Insurance Fund do not cover balances, and Curve's UK terms warn that in an insolvency the amount returned could be less than your balance after administrators' costs.
Does Curve cost anything if I never go abroad?
On the free plan, domestic spending in your card's own currency carries no Curve fee. The charges that bite are foreign exchange beyond the monthly allowance, ATM withdrawals, paying government agencies with a credit card through Curve Fronted at 2.5%, and a surcharge for using a commercial card on a personal account.
Which Curve plan is worth paying for?
Only Curve Pay X at £5.99 a month is an easy call, and only if you spend abroad: it removes the weekend surcharge, cuts the foreign exchange charge above the allowance, and lifts that allowance from £250 to £3,333. Pro at £9.99 and Pro+ at £17.99 mostly buy larger allowances and longer retroactive card switching.
