Can I Switch a Spare or Empty Bank Account?
Updated September 2026 · 5 min read
Quick answer: Yes. CASS doesn't require you to switch your main account, hold a specific balance, or use the account for anything beyond meeting the offer's conditions. A dedicated "switching account" is a common, valid strategy.
You don't need to switch your everyday, salary-receiving account to claim a bank switching bonus. Many people deliberately keep their main account untouched and use a separate, low-activity account purely for switching.
Why this works
CASS switches whatever account you tell it to — there's no requirement that the account be your primary one, hold your salary, or have any particular balance. As long as the account meets the specific offer's conditions (typically two active Direct Debits and a minimum pay-in), it qualifies, regardless of what else it's used for.
How a "spare account" strategy typically works
- Open a basic current account specifically for switching purposes — separate from your main banking
- Set up two Direct Debits on it (or maintain a BeSwitchReady membership, which does this automatically)
- Transfer in whatever minimum pay-in the target offer requires, meet any card-spend condition, then switch
- Once the bonus is paid, decide whether to keep using the new account, switch it again for another offer, or close it
Keeping your main account untouched has a real benefit: your salary, existing Direct Debits, and day-to-day banking stay undisturbed, while your switching activity happens entirely separately. Many serial switchers specifically avoid moving their main account for exactly this reason.
Does the account need a minimum balance to switch?
No — CASS transfers whatever balance exists, including zero. What matters for the bonus itself is meeting the specific offer's pay-in requirement after the switch completes, not what was in the account beforehand.
What to watch out for
- Some banks have minimum activity requirements to avoid account closure for inactivity — check the specific account's terms if you plan to leave it largely unused after claiming a bonus
- Managing multiple accounts means more logins and more things to track — worth weighing against the value of each individual bonus
Ready for a dedicated switching account
Whether you're switching your main account or a dedicated spare one, you need the same two active Direct Debits either way. BeSwitchReady provides them permanently, for £1.98/month total.
