If you're serious about earning from bank switching, the order you switch in matters. Claim the wrong offer first and you might lock yourself out of a bigger bonus later, or fall foul of a banking-group exclusion you didn't know about. This guide explains why order matters — and gives you a free tool to build your own optimal sequence based on your specific situation.
Most banks have eligibility windows — periods during which you can't claim their bonus again if you've already received one, typically around 3 years. Some also exclude people who currently hold accounts at affiliated banks. Switching in the wrong sequence can accidentally disqualify you from a future offer.
Key principle: banks within the same group often share eligibility rules — hold an account with one, and you're excluded from the others' switching bonuses. The main groups currently relevant: HSBC / First Direct, and NatWest / RBS / Ulster Bank. Always check this before switching, not after.
Because live offers, deadlines, and eligibility rules change monthly, a static "switch in this exact order" list goes stale fast — which is exactly why we built the calculator above instead of just publishing a fixed sequence. It always reflects what's actually live right now.
This is where most people lose momentum. When you do a CASS switch, your Direct Debits transfer automatically to the new bank. But if a switch goes wrong or you cancel prematurely, you can end up with no active mandates — and suddenly you're ineligible for the next offer.
A BeSwitchReady membership solves this permanently. Your two £0.99/month Bacs Direct Debits transfer with every CASS switch automatically, keeping you eligible for the next offer without any admin.
BeSwitchReady membership (£1.98/month total — £0.99 each) maintains your two Direct Debits across every switch, plus sends you a monthly newsletter telling you exactly which offer to target next — including deadlines and step-by-step claiming instructions.
