Autumn Budget 2025: changes to Cash ISAs

News

26 Nov 2025

Today’s Autumn Budget confirmed that the government will reduce the Cash ISA limit from £20,000 to £12,000, effective from April 2027.

This change will not apply to savers aged 65 and over, who will retain the current £20,000 Cash ISA limit. 

What does this mean for you?

Currently, you can save up to £20,000 tax-free each financial year in an ISA. This can be entirely in a Cash ISA or split across different types. For the tax year 2026/27, you’ll still be able to take full advantage of your £20,000 tax-free ISA allowance, whether in a Cash ISA or across other ISA types.

While we’re disappointed to see the Cash ISA limit reduced, £12,000 per year remains a substantial allowance for most savers. We’re also pleased that those aged 65 and over will continue to benefit from the full £20,000 limits - a welcome concession for our older members.”
