How UK Savings Rates Compare
UK savers currently benefit from some of the highest interest rates in years, thanks to the Bank of England base rate. While high street banks typically offer 1-2%, fintech platforms and investment apps are passing on much more competitive rates.
XTB and Revolut lead the pack at 4.00%, making them particularly attractive options. For those preferring traditional banking apps, Monzo provides 3.65% and Starling offers 2.50%.
FSCS Protection at a Glance
FSCS (Financial Services Compensation Scheme) protection is one of the most important factors when deciding where to keep cash. Bank deposit and investor protection are different schemes with different limits, and not every UK platform offers the same coverage. The deposit limit was raised from £85,000 to £120,000 per person per banking group in December 2025. Investor protection remains at £85,000.
| Provider | Bank deposit FSCS | Investor FSCS | How cash is held |
|---|---|---|---|
| XTB | No | Yes (£85k) | Cash held with regulated UK banks under CASS rules |
| Revolut | Yes (£120k) | n/a | Full UK bank licence since 11 March 2026. Savings via ClearBank, current account via Revolut Bank UK Ltd. |
| Trading 212 | Yes (£120k) | Yes (£85k) | Cash split across Barclays, NatWest, JPMorgan partner banks; investor cover applies if T212 itself fails |
| IG | No | Yes (£85k) | Client money held in segregated CASS accounts. Activity requirement applies. |
| Lightyear | Yes (£120k, NatWest portion) | Yes (£85k) | Cash held with NatWest plus QMMFs (money market funds, not FSCS-covered) |
| Webull UK | No | Yes (£85k) | Client cash in segregated accounts under FCA client money rules |
| Interactive Brokers | No | Yes (£85k) | UK entity is FSCS investor member. Accounts introduced to IB LLC (US) fall under SIPC instead. |
| Wise | No (e-money) | n/a | Funds safeguarded under EMR 2011, held with banks or insured. Wise Assets has separate FSCS investor cover. |
| Plum (Easy Access) | No (e-money) | n/a | E-money safeguarded, not FSCS-protected. Plum Cash ISA is a separate product with FSCS-protected partner banks. |
| Monzo | Yes (£120k) | n/a | Full UK banking licence; deposits FSCS-protected directly |
| Starling Bank | Yes (£120k) | n/a | Full UK banking licence; deposits FSCS-protected directly |
Bank deposit vs investor protection: Bank deposit FSCS (offered by Monzo, Starling, Revolut, and via partner banks at Trading 212 and Lightyear) covers your cash if the bank itself fails. Investor FSCS (offered by XTB, IG, Webull, IBKR, plus T212 and Lightyear on top of deposit cover) only kicks in if the broker fails, and covers up to £85,000 of cash and securities. E-money providers like Wise and Plum (Easy Access) are not banks and rely on safeguarding rules, which are robust but legally distinct from FSCS deposit cover.
Personal Savings Allowance and Tax
UK savers don't pay tax on the first slice of their interest each tax year, thanks to the Personal Savings Allowance (PSA):
- Basic-rate taxpayers can earn £1,000 of interest tax-free each year.
- Higher-rate taxpayers get £500 tax-free.
- Additional-rate taxpayers get £0.
At 4.00% AER, you'd hit the £1,000 PSA at around £25,000 of savings (basic rate) or £12,500 (higher rate). Above the allowance, interest is taxed at your marginal income tax rate.
If you're likely to exceed your PSA, a Cash ISA can be more tax-efficient. ISAs let you shelter up to £20,000 per tax year with all interest tax-free, regardless of your income tax band. The trade-off: ISAs typically pay slightly lower rates than the top high-interest savings accounts on this page, so the maths only works once you're close to or above the PSA.
What to Consider When Choosing a UK Savings Account
- FSCS Protection: Most UK banks and FCA-regulated platforms protect deposits up to £85,000 under the Financial Services Compensation Scheme.
- Access restrictions: Some accounts require you to hold investments or have trading activity. Check the terms before depositing.
- Rate changes: Most rates are variable and track the Bank of England base rate. Expect changes when the BoE adjusts rates.
- Tax considerations: Interest earned outside an ISA may be subject to income tax above your Personal Savings Allowance.

How We Rank These
Our ranking is based on the AER advertised on each provider's official website, verified directly on 6 May 2026. We weight providers by:
- Headline rate available without unusual conditions (no required deposits, no withdrawal penalties beyond what's noted in the table).
- FSCS or equivalent protection, which we summarise above.
- Withdrawal flexibility: we mark notice accounts and tiered withdrawal limits in the body sections.
- Balance caps and tier requirements: where a rate only applies up to a limit or requires a paid plan, that's noted alongside the rate.
We update this article monthly. Each cycle we re-verify every published rate against the provider's own website, never an aggregator. If we can't verify a rate from the source, we flag the provider rather than carry forward an old number. Our editorial process is run by MatchMyBroker.
