What are the best cash ISA rates right now?
The best cash ISA rates in October 2025 offer up to 4.51% AER for easy access options and 4.27% AER for one-year fixed terms, providing tax-free returns for UK savers maximising their £20,000 annual allowance. These rates, influenced by Bank of England base rate stability, beat standard savings accounts after tax for many. Easy access suits those needing flexibility, while fixed rates lock in security amid potential 2025 cuts projected by experts like Martin Lewis.
Cash ISAs, or Individual Savings Accounts, shield interest from income tax, with AER (annual equivalent rate) showing the true yearly return including compounding. Over 15 million adult ISAs were held in 2023-2024, up significantly, per HMRC data, highlighting their popularity for tax-efficient saving.
For projections, rates may dip to 4-4.2% by year-end if inflation eases, but acting now secures higher yields. Compare providers like those on MoneySavingExpert for the best cash ISA rates UK-wide.
Top easy access cash ISAs
Highest easy access cash ISA rates hit 4.51% AER from providers such as Plum, allowing penalty-free withdrawals anytime. This beats the 4.45% from Virgin Money, ideal for emergency funds within the FSCS-protected £85,000 limit per institution.

Best fixed rate cash ISAs by term
For locked-in security, the best fixed cash ISA rates offer 4.27% AER on one-year terms from MoneySavingExpert’s top picks, like Shawbrook Bank, with no access until maturity. Two-year options yield 4.10% AER, suiting medium-term goals, while five-year deals at 3.90% AER appeal for long-haul planning despite penalties for early withdrawal (up to 180 days’ interest).
One-year fixed suits short-term savers; compare best 1 year cash ISA fixed rates to avoid missing out. Longer terms protect against rate falls but limit liquidity—ideal if you have emergency savings elsewhere.

|---|---|---|---|---|
| Shawbrook Bank | 1 year | 4.27 | £1,000 | 90 days’ interest |
