The best UK savings rate depends on access needs and tax position. Easy-access: up to ~4.55% AER on meaningful balances (Tembo Money, cahoot, Chase’s new-customer Boost) — small capped accounts pay 5%. 1-year fixed: ~4.85% (MBNA, with Vanquis close behind). 3-5 year fixed: up to ~5.0% (Investec, Afin Bank, Chetwood Bank). Cash ISAs now match or beat taxable easy access (up to ~4.6%, tax-free). Accounts below sit within FSCS protection — £120,000 per person per banking licence (cahoot shares its licence with Santander).
Indicative easy-access + notice rates (August 2026)
| Provider | AER (variable) | Notes |
|---|---|---|
| cahoot Sunny Day Saver | ~5.0% | Max £3,000 — headline rate, small balances only; FSCS limit shared with Santander |
| Tembo Money Easy Access | ~4.55% | Savings platform — deposits sit with partner banks; includes 12-month bonus; max £20,000 |
| cahoot Simple Saver | ~4.52% | 12-month issue; up to £500,000; FSCS limit shared with Santander |
| Chase UK Saver (with Boost) | ~4.5% | New Chase customers, 12 months; standard rate 2.25% |
| Tesco Bank Internet Saver | ~4.21% | Includes 3.16% 12-month bonus; reverts to ~1.05% |
| Cynergy Bank Online Easy Access | ~4.15% | Includes ~2% bonus for first 12 months |
| Marcus by Goldman Sachs Online Saver | ~3.75% | Includes 0.49% 12-month bonus |
| BLME 90-Day Notice | ~4.37% | Expected profit rate; 90 days notice |
| Bank of England base rate (reference) | 3.75% | The benchmark — held 30 July 2026 |
Indicative fixed-rate bond rates (August 2026)
| Term | Best provider examples | Indicative AER |
|---|---|---|
| 6-month fixed | Oxbury Bank | ~4.82% |
| 1-year fixed | MBNA, Vanquis Bank | ~4.78-4.85% |
| 2-year fixed | Investec, Vanquis Bank | ~4.85-4.95% |
| 3-year fixed | Afin Bank, Investec | ~5.0% |
| 5-year fixed | Chetwood Bank, Afin Bank | ~5.0% |
Unusually, the longest fixes currently top the tables — 3- and 5-year money reaches 5.0% against ~4.85% for one year — as markets price Bank Rate staying higher for longer. UK fixed-rate bonds remain inflation-vulnerable: a 5-year lock at 5.0% comfortably beats today’s 2.9% CPI, but if inflation climbs back above your locked rate you lose real purchasing power. The trade-off is rate certainty vs duration risk. Most UK savers split balances between a 1-year fixed (certainty) and easy-access (flexibility).
Cash ISAs, regular savers and Premium Bonds (August 2026)
Three more places the best cash rates hide — including the tax-free accounts behind the claim above that Cash ISAs now match taxable rates:
| Account | Indicative AER | Notes |
|---|---|---|
| Sidekick easy-access Cash ISA | ~4.61% | Bonus-boosted; new-money conditions apply |
| Trading 212 Cash ISA | ~4.56% | Includes 0.96% 12-month bonus on new ISA money |
| Chip easy-access Cash ISA | ~4.55% | Accepts transfers in |
| Charter Savings Bank easy-access Cash ISA | ~4.23% | Bonus-free — no 12-month cliff edge |
| Best 1-year fixed Cash ISA | ~4.72% | Al Rayan (expected profit rate), with UBL UK and Vida close behind |
Regular savers pay the highest headline rates of all — up to 8% (Lloyds fixed, Santander variable) and 7% at First Direct — but only on monthly deposits capped at roughly £150-£300, and usually only for that bank’s current-account customers. Because the balance builds month by month, the cash you actually earn over the year is roughly half what the headline suggests on the full amount saved.
NS&I Premium Bonds pay no interest at all — instead the prize fund runs at 4.35% a year from the September 2026 draw, with the odds of any prize per £1 Bond at 21,000 to 1. Prizes are tax-free and the capital is 100% Treasury-backed with no FSCS limit, but the typical holder wins below the headline rate. Our Premium Bonds vs savings comparison runs the numbers by tax band.
Cash ISA vs taxable savings — when does ISA wrapper matter?
Cash ISA interest is tax-free; non-ISA savings interest counts toward the Personal Savings Allowance (£1,000 for basic-rate, £500 for higher-rate, £0 for additional-rate taxpayers).
| Tax band | Balance at 4.5% AER before interest becomes taxable |
|---|---|
| Non-taxpayer with no other income | ~£412,000 (PA + £5,000 starting rate + PSA; the starting rate shrinks £1-for-£1 with income above £12,570, so even modest earnings cut this sharply) |
| Basic-rate (£12,571 - £50,270) | ~£22,000 |
| Higher-rate (£50,271 - £125,140) | ~£11,000 |
| Additional-rate (£125,141+) | £0 — every penny taxable |
So for higher-rate taxpayers with more than ~£11k of cash — and for additional-rate taxpayers with any cash at all, since their PSA is £0 — the Cash ISA wrapper is essential to avoid tax. For basic-rate taxpayers with <£22k of cash, a normal savings account is fine — though in August 2026 the best Cash ISAs actually pay level with or slightly above the best taxable easy-access accounts, so compare the easy-access table and the Cash ISA rates above before assuming either way.
The savings interest tax calculator works out the exact effect of moving to a Cash ISA at any balance and band.
FSCS protection — the £120,000 limit per institution
Each UK bank or building society in the FSCS scheme protects your deposits up to £120,000. Above that, you should split across providers. Important: different brands can sit under the same banking licence, in which case they share one £120,000 limit.
Examples of shared FSCS limits:
- HSBC and First Direct = one £120,000 limit between them
- Lloyds, Halifax, Bank of Scotland = one £120,000 limit
- Santander UK and Cahoot = one £120,000 limit
- RBS, NatWest, Ulster Bank (Northern Ireland) = historically separate licences — confirm current groupings with the FSCS protection checker before relying on them
The FSCS protection checker verifies which licence each provider sits under.
Common UK savings mistakes
- Leaving money in legacy accounts at 0.1%. Many UK savers have £20-50k earning 0.1% AER in old NatWest / Lloyds / Barclays current accounts. Moving to a 4.5% saver adds roughly £880-£2,200 a year of gross interest on the same money — less any tax due above your PSA.
- Forgetting to file Self Assessment if interest exceeds £10,000. HMRC adjusts tax codes for smaller amounts. £10k+ savings interest requires SA registration.
- Ignoring Cash ISA wrapper as higher-rate taxpayer. Above ~£11k of cash, higher-rate taxpayers lose ~£180 a year to tax for each additional £10k held outside an ISA at 4.5% rates.
- Treating "Inflation +1%" as the goal. CPI inflation is 2.9% in the year to July 2026. Best easy-access at ~4.5% gives ~1.6% real return before tax (a higher-rate taxpayer past the PSA nets ~2.7% — slightly below inflation). Locking money away for 5 years at 5.0% gives ~2% real today — but less if inflation rises.
- Splitting unnecessarily across <£120k. One bank up to £120,000 is fine. Many savers waste energy spreading £30k across 3 banks.
