The UK government has confirmed that the annual Cash ISA allowance will remain at £20,000 from 6 April 2027. The previously announced reduction to £12,000 for customers under 65, together with the related restrictions, will not go ahead.
The £20,000 allowance remains an overall annual limit shared across all your ISAs and providers.
This announcement replaces the previously communicated plans. For details, read HMRC’s October 2026 update.
