Best bank switching deals UK 2026

Banking

Bank switching deals are one of the simplest ways to put extra money in your pocket without changing your spending habits. The Current Account Switch Service, guaranteed by Pay.UK and backed by all major UK banks, completes the move within seven working days and transfers your direct debits, standing orders and incoming payments automatically.

Cash incentives have fluctuated between £100 and £200 since 2022, with some providers also offering ongoing perks such as cashback on bills, fee-free overseas spending or linked savings rates. This guide sets out how switching works, what to look for in the small print, and the key facts for 2026.

How the Current Account Switch Service works

CASS is a free service run by Pay.UK that moves your current account to a new bank within seven working days. Once you apply, the new bank contacts your old one, transfers all direct debits and standing orders, and redirects any payments sent to your old sort code and account number for a minimum of three years. If anything goes wrong during the process - a misdirected payment or a missed direct debit - the switching guarantee requires the new bank to refund any charges or interest incurred as a direct result.

You choose the switch date when you apply. Most banks allow online or app-based applications. The old account is closed automatically on switch day, so you do not need to contact the old bank separately. CASS covers personal current accounts, business accounts (through a parallel service) and some basic bank accounts.

What switching bonus eligibility conditions typically look like

Banks attach conditions to cash bonuses to reduce the cost of incentivising low-engagement customers who close the account immediately after claiming the reward. Common eligibility conditions include: using a full CASS switch (partial switches rarely qualify); transferring a minimum number of active direct debits - often two or three; paying in a minimum monthly amount, typically between £500 and £1,500; and keeping the account open for a set period after the bonus is paid, usually 30 to 90 days.

Some banks also restrict bonuses to new customers who have not held an account with the same banking group within the past two to three years. Check the group structure carefully: First Direct and HSBC share a banking licence, for example, so a First Direct bonus may be unavailable if you currently hold an HSBC account.

Ongoing perks versus one-off cash bonuses

A switching bonus is a one-off payment, but some accounts offer ongoing value that can exceed the headline cash figure over 12 months. Cashback schemes that return a percentage of utility bills, council tax or supermarket spending can be worth significantly more than a single bonus for households with high regular outgoings. Interest-bearing current accounts - where a rate is paid on balances up to a set ceiling - are another form of ongoing reward, though rates have generally compressed as base rate expectations stabilise in 2026.

Fee-based packaged accounts often bundle travel insurance, breakdown cover or mobile phone insurance with a monthly fee. Before treating these as a perk, confirm the cover actually meets your needs: age limits, pre-existing medical condition exclusions and single-trip caps vary widely. MoneyHelper's account comparison guidance sets out what to check before signing up to a packaged account.

Tax treatment of switching bonuses

HMRC treats bank switching bonuses as miscellaneous income in most cases. For basic-rate taxpayers, the Personal Savings Allowance covers up to £1,000 of savings and interest income per tax year (2025/26), but switching bonuses may fall under a separate category depending on how they are structured. If the bonus is paid as a reward for a service - such as completing a set number of debit card transactions - HMRC may treat it differently from interest. If you are required to complete a self-assessment return, declare the bonus in the other income section. HMRC's official guidance on the tax treatment of bank incentives is available at gov.uk.

How to compare switching deals before you apply

The Financial Conduct Authority's rules on fair presentation of financial promotions require banks to make eligibility conditions clear. When comparing switching deals, note the following before applying: the full CASS switch requirement; the number of direct debits you must transfer; the minimum monthly pay-in; any spending or login requirements during a qualifying period; the timeframe in which the bonus is paid after meeting conditions; and any restriction based on previous banking group membership. Check the terms on the bank's own website rather than relying on comparison tables, as bonus amounts and conditions change without notice.

Frequently asked questions

Can I claim a switching bonus more than once?

Yes, provided you meet the eligibility conditions each time. Most banks restrict bonuses to new customers who have not held an account with the same banking group within a defined period - often 24 to 36 months. Once that exclusion window passes, you can switch back and potentially claim a bonus again if the bank is running a promotion.

Does switching affect my credit score?

Applying for a new current account usually triggers a hard credit search, which can cause a small, short-term dip in your credit score. The switch itself - closing the old account and opening the new one - should not have a significant lasting effect. Avoid applying for multiple new accounts in quick succession, as several hard searches in a short period can be viewed negatively by lenders.

What happens to my old account after I switch?

Under CASS, the old bank closes your account on the agreed switch date. Payments sent to the old sort code and account number are automatically redirected to the new account for at least three years. You do not need to notify every payer manually - the redirection service handles this. After three years, redirection is not guaranteed, so update any remaining payers to your new details before that point.

Is the seven-day guarantee legally enforceable?

The CASS guarantee is contractual rather than statutory, but participating banks are bound by the Payment Services Regulations 2017 and FCA rules on payment accounts. If a bank fails to honour the guarantee, you can complain to the bank first and then escalate to the Financial Ombudsman Service free of charge if you remain dissatisfied.

What if a direct debit is missed during the switch?

The switching guarantee requires the new bank to refund any charges or interest you incur as a direct result of a failed payment during the switch process. Contact the new bank immediately if a direct debit is missed. Keep records of any charges or default notices received, as these will support your refund request.
