Before the Portcullis Rises: A Risk-First Guide to Changing Current Accounts in 2026

Changing current accounts is not a test of loyalty. It is a piece of financial administration with a deadline attached. The Current Account Switch Service (CASS) is designed to move the plumbing—salary, benefits, direct debits and standing orders—from one bank to another within a set period, normally seven working days. The service has a guarantee and a redirect facility, but it does not remove the need for preparation. A switch is safest when it is treated as a controlled move, not a leap.

Begin with the account you have

Before comparing incentives, write down what your current account actually does. Note the date your salary or pension arrives, every direct debit and standing order, the arranged overdraft limit you rely on, and any regular payments made by card rather than by direct debit. The last category matters because recurring card payments—streaming services, gyms, some subscriptions—are not generally covered by the switch service in the same way as direct debits. They need to be updated separately.

Check whether the account is sole or joint. A joint account normally requires both holders to consent to the switch. Check whether it is a business account, a savings account or a packaged account with benefits attached; not every account is eligible for CASS, and some benefits may end when the account closes.

Know what the service moves—and what it does not

CASS asks your new bank to move the balance, close the old account and redirect payments that arrive at the old account for a period after the switch. It handles direct debits, standing orders, and regular credits such as salary and benefits. It does not automatically move saved payees, recurring card payments, digital wallets, or every linked service. It also does not decide whether the new account is right for you.

The redirect is a safety net, not a permanent address. If a payment is sent to the old account after the redirect period, it may be returned. That is why the weeks after a switch deserve attention rather than assumption.

Build a pre-switch inventory

A simple written inventory is the most useful tool. List each direct debit with the amount and usual collection date. List each standing order and its purpose. List regular credits: salary, pension, tax credits, child benefit, rental income or transfers from another account. Note any arranged overdraft and whether the new bank will accept it at the same limit. Note any linked savings account, debit card subscription or insurance policy that depends on the current account.

Then check the new account's terms. Look at the monthly fee, if any, the credit interest, the arranged overdraft rate, the unarranged overdraft charges, the ATM and foreign transaction charges, and the day-to-day features you actually use. A headline switching payment is welcome, but it is a one-off. The account's running costs and fit are what remain.

Verify the overdraft and the salary date

An arranged overdraft is not a separate account; it is a facility attached to the current account. If you switch while using it, the new bank must agree to take it on. Do not assume that because the switch service moves your balance, it will move your overdraft on the same terms. Ask explicitly. If the new bank offers a smaller limit, you may need to reduce the balance before switching or keep a separate buffer.

Salary timing is the other common point of friction. Most employers will update details through the switch service, but payroll cut-off dates vary. If your pay date falls close to the switch date, tell your employer's payroll team and check the first payslip after the move. The same applies to pensions and benefits.

Keep a reserve and keep your records

Keep a small backup balance in a separate account during the switch. It need not be large—enough to cover a few days of normal spending and one or two direct debits if a payment is delayed. This is not a criticism of the switch service; it is recognition that banks, employers and payment systems are separate pieces of machinery.

Download or print the old account's statements before it closes. You may need them for tax returns, mortgage or rental applications, benefit checks, expense claims or a dispute. Save the old bank's contact details and the switch reference. Keep a record of the switch date, the new account details and any payments you have redirected manually.

On the switch date and afterwards

On the switch date, check that the new account is open and that the opening balance is as expected. In the following days, check that salary or pension arrives, that direct debits are collected, and that standing orders leave on time. Check the old account is closed only when you are satisfied. If a payment is late or missing, contact the new bank first and then the originator. Keep notes of calls, dates and reference numbers.

Do not close or empty the backup account until at least one full payment cycle has passed. If you have an arranged overdraft, check its first interest charge. If you have a packaged account, confirm whether the benefits transferred or whether you need separate cover.

A conservative conclusion

Switching current accounts can be a sensible way to get better service, lower charges or a more useful app. The risk-first approach is not to avoid switching; it is to switch with a list, a reserve and a record. Choose the account that fits your ordinary month, not the one with the loudest offer. Move the plumbing deliberately, verify the first cycle, and keep the old paperwork until the new routine is proven. A portcullis is easier to raise when you know what is on the other side.
