Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what impact assessment he has made of the potential impact of changes to ISA regulation on retail investment trends.

The Government is committed to fostering a culture of retail investment across the United Kingdom, supporting individuals to secure better long-term returns on their savings while maintaining financial resilience. This includes various reforms to encourage retail investment, from the roll-out of targeted support to help people get the support they need to invest, to the industry led ‘Invest for Future’ comms campaign and reforms to investment risk warnings.

An assessment of the impacts of the changes to Cash Individual Savings Account (ISA) subscription limits that were announced at Budget 2025 was published on GOV.UK on 17 September 2026. The impact assessment can be found here:
