Chase UK wins on saver interest (currently ~3.6% AER instant access, ~4.85% on 90-day notice) and offers 1% cashback in first year. Starling wins on international transfers (real exchange rate, zero fee, anywhere). Monzo wins on app polish and budgeting features. Most active UK accounts now hold all three — they're complementary, not competitive.
The three accounts compared
| Monzo | Starling | Chase UK | |
|---|---|---|---|
| Owner | Independent (UK) | Independent (UK) | JP Morgan |
| Operating UK since | 2015 (banking licence 2017) | 2014 (banking licence 2016) | 2021 |
| Monthly fee | £0 (free) | £0 (free) | £0 (free) |
| FSCS protection | Up to £85,000 | Up to £85,000 | Up to £85,000 |
| Saver interest (instant access) | 1.0% on first £1k (Monzo Plus); up to 4.5% on Pots with paid plan | 4.0% on balances up to £85k (variable) | 3.6% (variable, no balance limit) |
| Notice saver / fixed | 5.0% on 90-day Notice (variable) | 4.5% on 1-year Fixed | 4.85% on 90-day Notice (variable) |
| Cashback | 1% on Plus (£5/mo) up to £100/yr | None on standard | 1% on debit card spending in first year (then conditional) |
| FX on card abroad | 0% on first £200/mo, then 3% (free) — unlimited 0% on Plus/Premium | 0% — unlimited, on all plans | 0% — unlimited |
| International transfers | Wise integration (small fee) | Free, real exchange rate | Wise-style (paid) |
| App quality (UK surveys) | Often #1 in usability surveys | Often #1 in customer satisfaction | Newer, less polished but improving |
| Branch access | None | None | None |
| Cash deposits via PayPoint | Yes (free up to £500/mo) | Yes (free) | No |
| Joint account | Yes | Yes | No (not yet) |
Saver interest — the biggest cost difference
For most active digital-bank customers, the interest rate on idle balances is the largest financial difference. Worked example: £20,000 sitting idle for one year:
| Bank | Interest earned on £20k over 1 year |
|---|---|
| Monzo (free, no pot) | £0 (no interest on main balance) |
| Monzo (free, instant Pot at 1%) | £200 |
| Monzo Plus (£5/mo, 4.5% Pots) | £840 (less £60 fee = £780 net) |
| Starling (4.0% on whole balance) | £800 |
| Chase UK (3.6% saver) | £720 |
| Chase UK (4.85% 90-day notice) | £970 |
For £85k+ balances (above FSCS protection limit), spreading across multiple banks is essential anyway.
Best use cases for each
Choose Monzo if you...
Best for: ...prioritise budgeting features, want the most polished app, like spending categorisation and Pots, value cashback (with £5/mo Plus)
Monzo’s app continues to win UK app surveys for usability. The categorisation, bill splitting, IFTTT-style automation and Pots system is hard to beat. The case for paid plans (Plus £5/mo, Premium £15/mo) depends on whether you’d use the higher interest Pots.
Choose Starling if you...
Best for: ...want the best interest on main balance, do international transfers, value zero-fee anywhere FX
Starling pays 4% AER on the whole balance up to £85k automatically — no Pots required. Free international transfers at the real exchange rate (not the bank-margin rate). Joint account available.
Choose Chase UK if you...
Best for: ...want 1% cashback in your first year, value the JP Morgan backing, want a saver paying 4.85%
Chase’s 1% cashback on debit-card spending was the headline feature at launch and remains compelling in year 1 (after that it gets more conditional). The 90-day notice saver at ~4.85% is currently the highest of the three. No joint account is the main gap.
Use all three (the optimal setup for most)
Best for: ...you can have multiple free current accounts — most people end up with 2-3
Common UK setup: Monzo for daily spending and budgeting; Starling for international + main saver; Chase as a saver-only account or for specific cashback months. All three free, all three FSCS-protected.
Common digital-bank mistakes
- Treating one bank as a complete solution. Each is best at something different. Most UK adults under 40 now run 2-3 free accounts.
- Ignoring FSCS limits. £85k per institution per person. If you hold £150k cash, split across at least two banks.
- Forgetting paid plans break even slowly. Monzo Plus at £5/mo (£60/yr) needs ~£1,500 of cashback or interest uplift to break even. Worth modelling for your usage.
- Using debit card abroad without confirming FX. Chase, Starling and Monzo Plus all give 0% FX. Monzo free has a £200/mo cap. Other UK banks charge 2.75-3% per transaction abroad.
- Mistaking digital-only for less safe. All three are fully FCA-regulated, FSCS-protected. They have less branch access, but for most under-40s this is irrelevant.
