How to earn hundreds in free switching bonuses using donor accounts, optimal sequencing, and CASS.
Donor Account
The account you switch FROM. Any current account with 2+ active Direct Debits.
Burner Account
A cheap/free account opened just to be your next donor. Open, add DDs, switch, repeat.
CASS
Current Account Switch Service. Moves your account, DDs, and payments in 7 working days.
Open a free basic current account with any bank. Good options: Starling, Monzo, or any high street bank that doesn't require a switch-in bonus. This becomes your donor.
CASS requires at least 2 active Direct Debits. Set up the cheapest ones possible. They must be proper Direct Debits — not card payments, not standing orders.
Wait until both Direct Debits have successfully collected at least once. This usually takes one billing cycle (about a month). Don't rush this — switching too early means the DDs won't transfer.
Apply for the bank account with the best available switching bonus. The application usually includes an option to switch via CASS during the process.
Most banks require you to pay in a minimum amount (often £1,000-£1,500) and use the account for a period. Set up a standing order from another account to meet pay-in requirements.
Once the bonus is paid (typically 1-3 months), you can start the cycle again. Open a new burner, set up DDs, and switch to the next bank.
Banks within the same group share eligibility restrictions. If you've switched to one, you usually can't claim a bonus from another in the same group until the cooling-off period expires.

Using card payments instead of Direct Debits
Netflix, Spotify, and mobile subscriptions paid by card do NOT count. You need proper Direct Debits (charity donations, energy, broadband).
Switching before DDs have collected
Wait for at least one successful collection from each DD before initiating the switch. Usually takes one billing cycle.
Not downloading old bank statements
You lose access to your old bank's app/online banking after the switch. Download or screenshot all statements first.
Ignoring banking group restrictions
Halifax and Lloyds are the same group. NatWest and RBS are the same group. Check eligibility before applying.
Applying during a mortgage application
Too many new accounts can spook mortgage lenders. Pause switching 6+ months before applying for a mortgage.
Open your next burner account the same day you complete a switch — this keeps the pipeline flowing
Use a dedicated email for bank accounts to keep bonus-related emails separate
Set calendar reminders for cooling-off expiry dates
Some banks count household income for joint accounts — switching as a couple doubles your bonuses
Keep at least one stable current account as your 'main' — don't switch your primary account
StoozeMax tracks your switches, cooling-off periods, and eligibility automatically.
