There’s a reason so many people stay with a bank account they’re not thrilled with. Switching bank accounts sounds like a hassle — updating direct debits, worrying about missed payments, dealing with new card numbers. In reality, the process in the UK has been designed to remove almost all of that friction.
If you’ve been putting off switching because it feels complicated, this guide should put your mind at rest. It genuinely is one of the more straightforward pieces of financial admin you’ll ever do.

Quick Answer
In short: Switching bank accounts in the UK is done through the Current Account Switch Service, which automatically transfers your direct debits, standing orders and incoming payments to your new account within seven working days. It’s free, and your old account closes automatically once everything has moved over.
Key Takeaways
- Switching is free and typically takes seven working days from start to finish.
- The Current Account Switch Service (CASS) automatically moves direct debits and standing orders.
- Payments sent to your old account by mistake are automatically redirected for three years.
- Not all banks participate in CASS, so check before starting the process.
- You don’t need to close your old account manually; it happens as part of the switch.
What Is the Current Account Switch Service?
The Current Account Switch Service, often shortened to CASS, is the system most UK banks and building societies use to make switching straightforward. Rather than you having to manually contact every company that takes a direct debit from your account, CASS handles the transfer automatically between your old and new bank.
Most major UK banks participate, and the guarantee behind the scheme means if anything goes wrong during the switch, such as a missed payment causing a fee, you’re refunded.
Step-by-Step: How to Switch Your Bank Account
Step 1: Choose your new account.
Compare fees, overdraft rates, app quality and any switching incentives before applying. Don’t apply for the new account until you’re confident it’s the right fit.
Step 2: Open the new account.
This is usually done online or via an app and can take as little as ten minutes, though full account activation may take a day or two.
Step 3: Start the switch through your new bank.
Once your new account is open, you’ll be asked whether you want to switch from an existing account. Provide your old account details and confirm.
Step 4: Choose your switch date.
You can pick a date up to a set number of working days ahead, giving you flexibility around payday or bill dates.
Step 5: Let CASS do the work.
Direct debits, standing orders, and incoming payments (like your salary) are transferred automatically. Your old account is closed once everything has moved.
Step 6: Check your new account is working as expected.
Log in a few days after the switch to confirm payments have moved correctly and your old account has closed.
What Happens to Your Old Account
Your old bank account closes automatically as part of the switch, assuming there’s no outstanding overdraft balance. If you owe money on the old account, you’ll usually need to clear that first or agree a repayment plan.
Any payments accidentally sent to your old account continue to be redirected to your new one for up to three years after the switch, which is a helpful safety net if you forget to update a payment detail somewhere.
What to Check Before You Switch
| Check | Why It Matters |
|---|---|
| Overdraft balance on old account | May need clearing before the account can close |
| Regular payments not covered by CASS | International payments sometimes need manual updating |
| Switching incentive terms | Some require a minimum monthly deposit to qualify |
| New account’s overdraft terms | Compare against your old account, not just headline rate |
| Timing around payday | Choose a switch date that avoids disrupting your cash flow |
Comparison: Switching vs Staying Put
| Factor | Switching | Staying with Current Bank |
|---|---|---|
| Cost | Free | No cost, but potentially higher ongoing fees |
| Effort | Roughly 10-15 minutes of admin | None |
| Risk | Protected by CASS guarantee | No risk, but no improvement either |
| Potential benefit | Better rates, app, or service | Familiarity only |
Common Mistakes When Switching
- Closing the old account manually before the switch completes. Let CASS handle this; closing it yourself can cause payments to fail.
- Switching right before a big bill is due. Choose a switch date that gives your new account time to settle first.
- Not checking if a specific payment is covered. International standing orders sometimes need manual attention.
- Ignoring the overdraft balance. If you owe money on your old account, resolve this before switching to avoid delays.
- Chasing switching bonuses without checking terms. Some bonuses require a minimum deposit or number of transactions each month.
Real UK Scenarios
Scenario 1: Ben, switching for a better overdraft rate.
Ben used his overdraft occasionally and was paying a high rate. He compared rates using MoneyHelper’s independent tools, switched to a lower-rate account, and saved a noticeable amount over the following year.
Scenario 2: Amara, switching for app features.
Amara wanted better spending categorisation for budgeting. She switched to a digital-first bank and found the automatic transaction tagging far more useful day to day.
Scenario 3: Callum, switching after a poor customer service experience.
After a frustrating dispute with his old bank, Callum switched providers entirely, prioritising a bank with strong customer service reviews over a slightly better interest rate elsewhere.
Expert Tips
- Time your switch for a quieter period in your finances, ideally just after payday rather than just before a big bill.
- Screenshot your list of current direct debits before switching, so you have a record to check against afterwards.
- If you’re switching for a bonus, read the small print on qualifying criteria before applying.
- Keep your banking app notifications on during the switch window so you can spot issues immediately.
