Chancellor Rachel Reeves will deliver her Spring Statement 2025 this month, which may introduce big changes for homeowners.
While not as big as the Autumn Budget, the Spring Statement is still an occasion to watch because it delivers big policy announcements. Here’s what could be on the cards for this year.
Stamp Duty
Stamp Duty Land Tax (SDLT) applies to property or land purchase exceeding a minimum in England and Northern Ireland.
In September 2022, the government increased these thresholds to boost the housing market. First-time buyers saw the threshold rise from £300,000 to £425,000, while for other buyers, it went from £125,000 to £250,000. This led to significant tax savings or even full exemptions for many buyers.
What Could Change?
These increased thresholds are set to revert to their pre-2022 levels in April 2025 unless the government extends them.

In spite of rumours of a last-minute U-turn, Reeves has indicated little willingness to keep the higher thresholds in the Spring Statement 2025. The chancellor is keen to plug a £22 billion budget deficit, and Stamp Duty is an important source of revenue.
If the thresholds are brought back down to their previous levels, demand for houses may fall, and house prices may drop.
ISAs & Home Buying
ISAs, particularly Lifetime ISAs (LISAs), have been a major contributor to helping first-time buyers save up for home purchases. LISAs provide a tax-free savings scheme whereby the government contributes £1 for every £4 saved, up to a bonus cap of £1,000 per annum.
However, the price limit for properties for free use of an LISA has been £450,000 since 2017, while house prices have escalated. All the buyers of properties over this threshold pay a 6.25% withdrawal penalty on their savings.
What Could Change?
There has been a longstanding demand from campaigners to increase the £450,000 price limit so that it will represent current property values and reduce the LISA withdrawal penalty.
While the previous Conservative administration did not address these issues, there is optimism Reeves may consider reforms. Experts suggest reducing the withdrawal penalty to 20%, meaning savers keep their government bonus unless they withdraw for non-housing reasons.
Cash ISAs, indirectly linked to house buying, have also been subject to speculation. Some have recommended cutting the ISA allowance from £20,000 to as little as £4,000 in order to encourage investment in stocks and shares instead.
Support for Mortgage Interest
Support for Mortgage Interest (SMI) is a state loan to help benefit claimants pay mortgage or home improvement loan interest. It is payable to recipients of Universal Credit, Pension Credit and certain other benefits.
Although SMI loans are charged interest, they can be helpful in making mortgage payments affordable.
What Could Change?
Reeves is planning significant welfare budget cuts, and in the Spring Statement 2025, SMI could be affected.
With the government spending over £137 billion annually on benefits, the chancellor is unlikely to introduce tax hikes and is instead focused on reducing public spending. As a result, the SMI scheme could be scaled back or even eliminated entirely.
Comparative Analysis of Potential Changes with Spring Statement 2025
Policy Area | Current Policy | Potential Change | Impact on Homebuyers |
|---|---|---|---|
Stamp Duty | Higher SDLT thresholds until April 2025 | Reverting to pre-2022 levels | Increased tax burden |
ISAs (LISA) | £450,000 cap, 6.25% withdrawal penalty | Potential cap increase, penalty reduction | More flexibility for savers |
Cash ISAs | £20,000 tax-free savings allowance | Possible reduction to £4,000 | Lower tax-free savings potential |
SMI | Available for benefit recipients | Potential reductions or removal | Reduced support for mortgage holders |
Conclusion
As the Spring Statement 2025 draws near, homeowners and first-time buyers need to be on the lookout for policy changes. The chancellor's emphasis on fiscal restraint hints that tax reliefs and house-buying incentives are under threat. Stamp Duty, ISA, or SMI changes would have a substantial impact on affordability and homeownership in the UK.
For home buyers, the coming months will dictate whether decisions by the government will have their backing or work against their own property plans.
