The Treasury laid the Individual Savings Account (Amendment) Regulations 2026 on 24 September 2026, introducing a £5,000 annual subscription limit for Cash ISAs within the overall £20,000 ISA allowance, effective from 6 April 2027. The measure, announced in the Spring Budget 2026, aims to incentivize long-term equity investment by restricting the amount of new money that can be placed in cash-based ISA products (including cash ISAs, Help to Buy ISAs, and Lifetime ISA cash components). The remaining £15,000 of the annual allowance can be utilized in Stocks & Shares ISAs, Innovative Finance ISAs, or the new ‘British ISA’ for UK-equity-focused funds.
Key Takeaways
- Transitional Protection: Existing Cash ISA balances are unaffected; the limit applies only to new subscriptions in 2027/28 onwards. Savers can still transfer existing Cash ISA funds between providers without counting toward the £5,000 limit.
- Provider Operational Changes: ISA managers must update systems to enforce the sub-limit, provide real-time subscription tracking across ISA types, and issue revised Terms & Conditions by 1 March 2027.
- Behavioral Economics Goal: The policy explicitly targets the ‘cash drag’ on national savings, with the OBR forecasting a £3.2bn annual shift into equity capital markets by 2029/30, supporting the government’s ‘Investment Zone’ agenda.
