Cash ISA allowance set to drop to £12,000
Reports indicate that the Cash ISA allowance will fall from £20,000 to £12,000 for under-65s starting 6 April 2027. The overall ISA allowance will remain at £20,000, but uninvested cash in Stocks & Shares ISAs may be capped to prevent bypassing the new limit. This change aims to encourage investment over cash savings, significantly impacting savers who rely on tax-free interest.

State Pension triple lock reform confirmed for 2030
Prime Minister Andy Burnham has confirmed plans to pass legislation scrapping the pensions triple lock before the next election, with changes taking effect from 2030. The government intends to use the savings from this reform to fund social care measures. Analysts warn that this could leave pensioners thousands of pounds worse off in future years compared to the current inflation-linked guarantee.
Stamp Duty abolition ruled out; thresholds under review
Despite previous speculation, the Prime Minister has ruled out immediate plans to abolish or radically reform Stamp Duty Land Tax (SDLT) in the upcoming Autumn Budget. However, reports suggest that thresholds could still shift to aid first-time buyers, who are increasingly dragged into paying the levy due to rising house prices. The tax remains payable within 14 days of property completion in England and Northern Ireland.

Gas unit rates have surged by approximately 27% year-on-year to nearly 8p per kWh, the highest level since early 2023.
