High-Street Banks & Dummy Accounts for UK Switching Bonuses 2025
High-Street Options
- Halifax allows you to open multiple accounts, which can be useful as dummies.
- Lloyds (Club Lloyds) has run several bonuses in the past two years:

- £200 in late 2024
- £175 in early 2025
- £185 in July 2025
Some switchers report earning up to £700 by timing multiple offers.
- Santander is more restrictive, usually only one account per type.
⚠️ Tip: Don’t repeatedly switch using the same bank as a dummy account. Spread switches across Chase, Monzo/Starling, Halifax, and Lloyds to avoid raising an unwarranted account flag.
Chase Sub-Accounts
Chase is one of the best dummy strategies. You can hold up to 20 current accounts plus 10 savers, each with unique details. Switch using a sub-account, not your main Chase account. This way, your relationship with Chase stays intact.
Another perk: Chase offers competitive savings rates for new customers. You can check my latest guide here: Best Savings Accounts UK – Aug 2025.
🔒 Mitigating the Impact on Credit Scores
Switching accounts can be rewarding, but each new current account application usually leaves a credit footprint. Here’s how to manage it:
- Space out your switches: Aim to leave at least 6 months between applications. This keeps your credit file from looking “credit hungry.”
- Avoid switching before big applications: If you plan to apply for a mortgage, car finance, or major loan in the next 6–12 months, it’s best to pause switching. Lenders prefer stability.
- Keep your main account open: Lenders like to see a long-standing current account, it signals financial reliability.
- Stick with soft-check banks for dummies: Monzo, Starling, and Chase sub-accounts typically use soft checks that won’t appear on your credit file.
- Don’t apply for overdrafts: This usually triggers a hard search. Keep dummy accounts simple and overdraft-free.

💡 Rule of thumb: Protect your future borrowing power first. Chasing a £150 switch bonus isn’t worth it if it jeopardises a good mortgage rate.
💳 Switch Smarter, Not Harder
Keep your debt organised while you earn switching bonuses.
Using the Current Account Switching Service (CASS)
To qualify for most bonuses, you need to use the Current Account Switching Service (CASS).
- Switch completes in 7 working days.
- Moves all direct debits, standing orders, and salary payments
- Redirects payments for up to 3 years
- Most banks require a full CASS switch to pay out bonuses.
Real-Life Strategy
Here’s how serial switchers make the most of it:
- Open a Monzo or Starling dummy account
- Switch into a high-street bank (e.g., Halifax or Lloyds) for a bonus.
- Use a Chase sub-account for your next switch.
- Keep your main account untouched throughout
This method can net hundreds of pounds each year with minimal effort.
