Banking sign-up bonuses are promotional rewards from UK banks and fintech apps for opening a new account. You've probably seen offers from Monzo, First Direct, NatWest, and others, typically £5 to £10 free cash just for signing up.
It's not a scam or a catch. Banks would rather pay you to try their app than spend thousands on adverts.
In this guide, you'll learn:
Yes. There's no legal limit on how many UK bank accounts you can hold. Many people have accounts with several banks, nothing dodgy about it.
Most basic current accounts are free. Some have inactivity fees if you don't use them for extended periods (typically 12+ months), so it's worth checking the terms.
Most bonuses require you to keep the account open for 30 to 90 days. After that, you can close it if you want, though many people keep them for the features.
It varies. Some banks credit your bonus instantly after meeting criteria. Others take up to 90 days. Each offer specifies the timeline, check before you sign up so you know what to expect.
Now you understand how banking sign-up bonuses work, you might be wondering how to actually make money from them.

It comes down to simple maths.
Traditional advertising costs banks £50 to £150 per new customer. A Facebook ad campaign, TV spots, tube posters. It all adds up. But a £5 or £10 referral bonus? That's a bargain.
The UK has one of the most competitive digital banking markets in the world. Challenger banks like Monzo, Lloyds, and Nationwide are all fighting for the same customers. Referral schemes are their most cost-effective weapon.
From a bank's perspective, you're not just worth £10. Over your lifetime as a customer, they earn money through:
Most banking sign-up bonuses use a refer-a-friend model:
Let's address the common concerns.
Will it affect my credit score?
No. Opening a standard bank account triggers a "soft" credit check only. Soft checks don't appear on your credit file and don't affect your score.
You'd only face a "hard" check if you applied for an overdraft, credit card, or loan, which isn't required to claim sign-up bonuses.
Are these banks legitimate?
All UK banks offering sign-up bonuses are authorised and regulated by the Financial Conduct Authority (FCA). Yes, even the ones with the trendy apps and hot coral cards. You can verify any institution at fca.org.uk/register.
Monzo, First Direct, and NatWest are all fully licensed banks with the same regulatory requirements as Barclays or HSBC.
What about my deposits?
Deposits up to £85,000 are protected by the Financial Services Compensation Scheme (FSCS). This applies to all properly authorised UK banks, including the challenger banks.
Do I have to pay tax on bonuses?
Sign-up bonuses count as miscellaneous income. Most people can earn up to
The process is similar across most digital banks:
1. Download the app
Most offers are mobile-only. You'll download from the App Store or Google Play.
2. Enter your details
Name, address, date of birth, the usual. Some apps pre-fill this if you've stored it on your phone.
3. Verify your identity
This is the bit that takes longest (usually 5-10 minutes). You'll photograph your ID (passport or driving licence) and often take a selfie for facial matching. Top tip: good lighting makes a difference. I've had a few rejections from dodgy photos taken in dim rooms.
4. Wait for approval
Most apps approve instantly. Some take 1-3 days for manual review.
5. Meet the bonus criteria
Read what's required. It might be just completing verification, depositing £1, or making a purchase on your new card.
6. Receive your bonus
Usually credited within a few days of meeting the criteria. Some banks pay instantly.
The whole process takes 10-15 minutes
A £10 welcome bonus is a small investment for what could be years of transaction fees. They're betting you'll stick around.
For most people doing a handful of offers, it's not a concern.
The criteria vary by bank. Some just need you to verify your identity. Others ask you to deposit £1 or make a purchase. Each offer spells out exactly what's required.
What about referral limits?
Most banks cap how many people you can refer (usually 5-10 per year). And they have systems to detect abuse, so no, you can't just create fake accounts.
Looking for larger bonuses? Bank switching offers through the Current Account Switch Service (CASS) typically pay £100 to £200, but they involve moving your entire current account. See our bank switching guide for more on that.
