Banks in the UK routinely pay customers to switch their current account, and the process is fully automated. Through the Current Account Switch Service (CASS), your entire account — balance, direct debits, standing orders, and regular payments — moves to a new bank in seven working days, with automatic forwarding of payments to the old account for 36 months. Bonuses typically range from £100 to over £200, and because HMRC treats them as gifts rather than income, they are completely tax-free. For the time invested — usually under thirty minutes of active effort — few side hustles come close.
How CASS actually works
The Current Account Switch Service is a free, government-backed system designed to make bank switching painless. You apply to the new bank and elect to switch via CASS. From that point, the new bank handles everything: your balance is transferred, all direct debits and standing orders are moved across, and the old account is closed. Seven working days later, everything is running at the new bank.
Payments accidentally sent to the old account after the switch are automatically forwarded for 36 months, giving employers, benefit agencies, and subscription services ample time to update their records. The service moves everything linked to your current account — though savings accounts, credit cards, and investments held separately are not included and must be transferred independently.
The key thing to understand is that the bonus is almost always conditional on using CASS. Simply opening a new account and manually transferring money will not qualify. When you apply, make sure you select the switching option.
What banks are offering now
Bonus amounts and conditions change frequently, so always check the bank’s website or a comparison site such as MoneySavingExpert before committing. As of mid-2026, typical offers include First Direct at £175 (requiring a monthly pay-in of £1,000, two direct debits, and online banking), HSBC at £150 (monthly pay-in of £1,500 via CASS), Nationwide at £100 (available to existing members through the Fair Share bonus), and Club Lloyds at £100 (monthly pay-in of £2,000 via CASS). Barclays and other high-street banks also run periodic offers — check their current deal.
Meeting the conditions
Every bank sets its own requirements, and they tend to follow a pattern. The most common condition is a minimum monthly pay-in, typically £1,000–£2,000, which can be met through salary, a pension payment, or a transfer from another account you control. Banks also usually require you to set up two to three direct debits on the new account — utilities, phone bills, subscriptions, or charitable donations all count. You will generally need to log in to online or mobile banking within a set period, and some banks require you to hold the account for three to four months before paying the bonus.
Reading the terms and conditions carefully is not optional. Missing a single requirement — failing to set up a direct debit within the deadline, or not logging in to online banking within the specified window — can disqualify you entirely.
Eligibility: who qualifies
Not everyone is eligible for every bonus. Most banks will not pay if you already hold — or have recently held — an account with them, and many restrict bonuses to once per 12–24 months. You must be 18 or older, a UK resident with a UK address, and you must not have received a switching bonus from the same bank before. These rules vary by provider, so the terms are worth reading in full before you begin.
Beyond the one-off bonus
A common mistake is chasing the sign-up bonus without considering what the account offers on an ongoing basis. Some current accounts pay monthly rewards for meeting certain criteria. Club Lloyds, for example, offers cinema tickets, magazine subscriptions, or Disney+ subscriptions worth up to roughly £180 per year. Nationwide’s Fair Share bonus pays eligible members annually. First Direct provides a £250 overdraft buffer and consistently strong customer service ratings. NatWest offers cashback on bill payments through its Rewards account.
A few current accounts also pay interest on balances. Nationwide FlexDirect has historically offered 5% AER on up to £1,500 for the first year, and TSB’s Spend & Save Plus pays interest on balances. When comparing accounts, weigh the monthly fee against the rewards value, look at interest rates on credit balances, check the overdraft rate, and consider customer service quality and branch access. A £100 bonus paired with poor ongoing benefits may not be worth the switch.
Tax treatment
Bank switching bonuses are completely tax-free. HMRC treats them as gifts rather than income, so there is no Income Tax or National Insurance to pay and no need to declare them on a tax return. This makes bank switching one of the cleanest and simplest ways to earn extra money available to UK residents.
A worked example: switching twice
Consider switching first to First Direct, then to HSBC. The First Direct switch takes around twenty minutes to set up: apply online via CASS, pay in £1,000 per month (salary or a transfer from savings), set up two direct debits such as council tax and a phone bill, and log in to online banking within the first month. After meeting the conditions for three months, the £175 bonus is paid.
You then switch from First Direct to HSBC via CASS — roughly fifteen minutes of active time. Pay in £1,500 per month, transfer your existing direct debits, wait three months, and receive the £150 bonus. Total time spent: around thirty-five minutes. Total earned: £325. That works out at roughly £550 per hour of effort, which outperforms virtually any other side hustle on an hourly basis.
A disciplined approach — switching once or twice a year, always reading the terms, and keeping a basic backup account open for emergencies — can accumulate £500–£1,000+ in total bonuses over a few years with minimal disruption to your day-to-day banking.
How to start
Check current offers on MoneySavingExpert or MoneyHelper, pick a bank with a bonus you qualify for, and apply online selecting the CASS switching option. Provide your old bank details (account number and sort code), set up the required direct debits on the new account within the specified timeframe, pay in the minimum amount each month, and log in to online banking as required. The bonus typically appears within one to three months of meeting all conditions.
Keep a spreadsheet tracking each switch — dates, bonuses earned, and requirements met — so you do not lose track of deadlines or accidentally miss a condition. Set calendar reminders for when conditions must be fulfilled. And remember: every bonus is tax-free, so what you earn is what you keep.
