Cut to cash ISA allowance
Tuesday 6th April, 2027
The UK government has announced that, from 6 April 2027, the annual cash ISA subscription limit for savers aged under 65 will be reduced to £12,000 (within the overall ISA annual limit of £20,000), as set out in the 2025 Budget. The change is part of ISA reform intended to encourage longer-term investing and will be implemented by legislation and industry consultation ahead of the commencement date.
Why have we flagged this?
Savers with reduced cash ISA allowances may adjust short-term savings and housing plans (deposits, mortgage buffers); Rightmove can use data on searches, buyer sentiment and offer guidance on saving for deposits or alternatives, plus expert comment on how this affects first-time buyers and movers.

The £12k house hunt

Why: A browsable, mappable list lets every regional outlet localise the story, while the ‘£12k belt’ gives nationals a neat, counterintuitive geography of affordability to cover.
