Best Cash ISA Rates July 2026: Easy Access & Fixed AERs

The easy-access table has shifted upward since our last update. Trading 212 now pays 4.63% AER — 12 basis points higher than the 4.51% it offered through May. The bonus component still dominates: the base rate remains modest, with a chunky introductory supplement that expires after 12 months. The post-bonus underlying rate is materially lower — do not treat this as a permanent 4.63%.

Trading 212 — 4.63% AER. The market leader for new money. The rate is variable and includes a promotional bonus. After month 12 you revert to the base rate, which sits below Bank Rate. Set a calendar reminder for July 2027. Money sits in a ring-fenced client account at Barclays, NatWest or JPMorgan with FSCS protection of £120,000 per banking group on cash deposits.

Chip — 4.42% AER. This is the new best pick for ISA transfers, per MSE's latest table. Chip's app-only interface means no phone support, but the rate is competitive and transfers in are accepted — critical if you are consolidating old ISAs paying sub-2%.

Tembo — 4.06% AER and Leeds Building Society — 4.05% AER remain the no-bonus, no-expiry, no-diary-entry picks. These rates have held firm through the BoE's two successive holds. For hands-off savers, the gap between these and Trading 212's post-bonus rate means Tembo wins from month 13 onwards — same structural truth as two months ago, now with a wider starting gap.

Virgin Money — 4.15% AER variable, no bonus. Now part of Nationwide: check your combined exposure across both brands stays under the £120,000 FSCS limit. Still the best household-name option.

The pattern is unchanged: bonus-chasing pays in year one, no-bonus pays in year two. The difference is that the bonus gap has widened — Trading 212 now offers 57 basis points over Tembo in year one, up from 45. That makes the year-one calculus stronger, but only if you actually leave on schedule.

The fixed-rate market got a genuine shake-up on 29 June when NS&I launched new fixed-rate savings paying up to 4.69%. This is government-backed money — HM Treasury guarantee, not just FSCS — and it lands at a rate that beats every ISA fix currently on MSE's table. NS&I products sit outside the ISA wrapper, but at 4.69% gross they force ISA providers to compete or lose flow.

1-year fixed: Coventry Building Society — 4.60% AER. The new table-topper for ISA-wrapped one-year money. Coventry allows transfers in. For non-ISA money, compare against NS&I's 4.69% and do the tax maths.

2-year fixed: Hodge Bank — 4.66% AER. The highest ISA-wrapped fixed rate on the market as of 30 June. Two years takes you through roughly four MPC meetings and into mid-2028 — long enough to ride out the current "hold" phase but short enough that you are not committing past the 2027/28 ISA regime change without an exit.

Longer fixes: The 3-year and 5-year space has not repriced upward. Earlier in 2026, Close Brothers led at 4.53% for 3 and 5 years. With UK 10-year gilt yields at 4.94% in May — down from the 5.1% spike during the early-May Iran-war yield blowout but still elevated — the wholesale market continues to offer more than retail fixed-rate ISAs. The gap has narrowed but not closed. Anyone who can hold to maturity and is already maxed on their ISA allowance should price the direct gilt alternative.

The chart tells a simpler story than two months ago. The gilt-to-ISA premium has compressed from ~57bp in early May to ~28bp today. The case for holding gilts outside an ISA over ISA-wrapped fixes is weaker — but still present for higher-rate taxpayers who have exhausted their allowance. More on that arithmetic in the next section.

For the slice of your savings above £20,000 — the part that cannot fit in the 2026/27 ISA allowance — the wrapper question matters. And with UK gilt yields at 4.94%, the answer is less dramatic than it was during the May spike but still tilted toward gilts for the right taxpayer.

UK government bonds enjoy a tax quirk that cash savings do not: capital gains on gilts are exempt from CGT. This makes low-coupon gilts trading at a discount to par particularly efficient. You take a small taxable coupon — taxed as savings income — and a chunky tax-free gain as the bond pulls to par at maturity.

Three conditions need to hold for gilts-in-GIA to beat ISA-wrapped cash:

• You are a higher-rate or additional-rate taxpayer with savings already above £20,000
• You can hold to maturity (selling mid-life crystallises a mark-to-market loss if yields rise further)
• You have used your 2026/27 ISA allowance, so the marginal pound is taxed either way

If all three hold, a low-coupon 5-year gilt yielding ~4.9% to maturity probably edges a 4.66% fixed-rate ISA after tax — and the edge grows from April 2027 when the savings higher rate climbs from 40% to 42%. But the margin has shrunk: in May a 57bp spread made the decision easy; today's ~28bp spread makes it a closer call that depends on your exact tax position and whether you value the ISA's administrative simplicity.

The cash ISA wrapper remains the right answer for the first £20,000 — there is no substitute for permanent tax-free compounding. It stops being the right answer at £20,001 for taxpayers who can handle a gilt's price volatility.

"Best" is a useless word without context. Here is what it means by saver type, with the actual top pick for each as of 1 July 2026:

The Switcher (will move providers every 12 months). Best pick: Trading 212 at 4.63%. Bonus expires roughly July 2027 — diary entry mandatory. Year-one return on the full £20,000 allowance: £926. That is £24 more than the same strategy earned in May, entirely from the rate bump.

The Set-and-Forget Saver (will not switch). Best pick: Tembo at 4.06% or Leeds BS at 4.05%. No bonus to expire, no calendar maintenance. Year-one return on £20,000: £812. The gap between this and the forgetful Trading 212 customer — who drops to the post-bonus rate in year two — compounds year after year. Hands-off savers should never open a bonus account.

The Rate-Locker (wants to fix current yields). Best pick depends on wrapper availability. For ISA-wrapped money: Hodge Bank 2-year fix at 4.66% is the table-topper, paying £932 on £20,000 in year one and repeating. For non-ISA money above the allowance where the tax comparison matters: run the NS&I 4.69% against a low-coupon gilt at ~4.9% and pick whichever nets more after your marginal rate.

The Higher-Rate Taxpayer (£500 PSA, 42% savings rate from April 2027). Best pick: any ISA that you will actually use. The wrapper does the heavy lifting. A 4.05% ISA beats a 4.69% taxable account (NS&I) at the higher rate once the 2027 tax hike lands — the ISA pays £810 tax-free, while the taxable account nets roughly £752 after the 42% rate bites on interest above the £500 PSA. The wrapper is worth more than the rate spread.

Picking the wrong saver category costs you real money. A higher-rate taxpayer chasing 0.57 percentage points of extra headline rate by going into a Trading 212 bonus they forget to switch would be worse off than someone who opened Tembo at 4.06% and walked away — the crossover happens in month 13.

For the broader comparison framework between cash and other savings options, see the £50,000 framework.

All three scenarios assume the full 2026/27 allowance deposited on 6 April 2026 and held to 5 April 2031. Returns shown are simple interest compounded annually with rates held at current levels — actual figures will vary by future rate moves, daily/monthly interest calculation and any switching gaps.

Scenario A — Trading 212 4.63% with annual switching. Year one earns 4.63%. Year two onward assumes you successfully switch each July to whatever leads the easy-access table (held flat at 4.10% as a conservative central estimate — roughly the current no-bonus rate). Five-year balance: roughly £24,630. Total interest: £4,630.

Scenario B — Trading 212 4.63% but you forget to switch. Year one earns 4.63%, then years two through five earn the post-bonus rate (estimated at 3.60% based on the previous bonus structure). Five-year balance: £24,197. Total interest: £4,197. Forgetting once costs you £433 from the active-switcher path.

Scenario C — Tembo 4.06% no bonus, no switching. Earns 4.06% throughout. Five-year balance: £24,407. Total interest: £4,407. Within £223 of the active-switcher path — and ahead of the forgetful Trading 212 customer by £210.

The active-switching premium is real but modest — roughly £173 over five years versus Tembo — and it is fragile. One missed switch and you have wiped it out. The Tembo path requires exactly zero diary entries across five years and still finishes within £200 of the perfect-execution switcher.

For higher-rate taxpayers the comparison sharpens further from April 2027. £20,000 at 4.06% in a Tembo ISA earns £812 tax-free annually. The same money in a 4.69% NS&I taxable account earns £938 gross, but the £500 PSA covers only the first slice — the remaining £438 is taxed at 42%, removing £184. Net: £754. The lower-rate ISA wins by £58 in year one, and the gap widens annually through tax-free compounding.

Two policy deadlines and one macro shift make this tax year worth more than it looked in May.

First, the HMRC technical note confirms that from 6 April 2027 the cash ISA allowance for under-65s drops from £20,000 to £12,000. The overall ISA limit stays at £20,000, but only £12,000 can go into cash. The remaining £8,000 must go into stocks and shares or sit unused. Transfers from S&S ISAs back into cash will also be banned. That door closes one way — and you have nine months left to walk through it.

Second, the same note raises the savings basic rate from 20% to 22% and the higher rate from 40% to 42% from 2027/28. The Personal Savings Allowance stays at £1,000 (basic-rate) and £500 (higher-rate). Every pound of interest above those thresholds gets taxed harder from next April — making the ISA wrapper more valuable, not less.

Third — and this is the change since May — CPI inflation has fallen from 3.3% to 2.8%. At 4.63% easy-access and 2.8% CPI, you earn a real return of roughly 1.83% inside the ISA wrapper. That is a 50% improvement in real purchasing power versus the 1.21% real return available in May. Cash ISA savers are actually gaining ground against inflation for the first time in the 2026/27 tax year.

The combined maths: every £8,000 contributed to a cash ISA in 2026/27 is permanently sheltered from the 2027 cap, and every pound of future interest escapes the 22%/42% regime. £8,000 compounding at 4% for 30 years grows to roughly £25,950 — all tax-free in the ISA. The same £8,000 in a taxable account at 4% with the excess above the PSA taxed at 42% grows to approximately £19,860 after tax. The lifetime cost of skipping this year's cash ISA allowance is not the £926 of year-one interest — it is something closer to £6,090 in lost tax-free compounding over three decades, on just the £8,000 you can never put back in.

This is the optimiser case, plainly stated: the real return has improved, the tax shield is about to shrink, and the compounding clock is running. Use every pound of the 2026/27 cash ISA allowance you can spare.

Open one now if any of these are true.

• You have savings above £20,000 (basic-rate) or £11,000 (higher-rate) — your PSA is already exhausted or close to it, so every pound of interest above that threshold is taxed today.
• You are a higher-rate or additional-rate taxpayer with any meaningful savings balance. The wrapper value increases in April 2027 when the rate rises to 42%.
• You can commit to switching providers annually and will actually do it. The Trading 212 4.63% bonus rate is the best easy-access return available — but only if you leave before the bonus expires.
• You want to fix and forget. Hodge Bank's 4.66% two-year fix gives you ISA-wrapped certainty through mid-2028 with no bonus expiry to track.
• You have old ISA balances paying sub-2% and have been meaning to consolidate. Chip at 4.42% accepts transfers. The 15-working-day transfer guideline means starting now gets you earning the new rate before August.

Consider waiting if:

• You might need the money within six months. Easy-access ISAs allow withdrawals, but the switching game only pays if you hold for the full bonus period.
• You are watching the BoE's 30 July MPC meeting. Markets price a hold, but a surprise cut would compress savings rates quickly. If you are rate-locking, fix before the decision — providers can pull deals within hours of a cut announcement.
• You are a basic-rate taxpayer with total savings under £20,000. Your £1,000 PSA probably covers all your interest, so the ISA wrapper adds no tax benefit. In that case, NS&I's 4.69% fixed-rate account (non-ISA) pays more — and carries a government guarantee — without you needing the ISA wrapper at all.
