April 2025 Stamp Duty Changes: One Year On, What Really Happened to the Property Market

The higher SDLT thresholds introduced on 23 September 2022, and made temporary in the Autumn Statement of 17 November 2022, were allowed to expire on 31 March 2025. From 1 April 2025, the standard nil-rate band reverted from £250,000 to £125,000, and the first-time buyer nil-rate band fell from £425,000 to £300,000.

These changes were widely anticipated and extensively reported, which is precisely why they generated the market distortions visible in the data. Use our pre vs post April 2025 comparison tool to see the exact impact on your purchase price.

Economists call it “forestalling”: the behaviour of buyers who accelerate transactions before an announced tax rise, or delay them to benefit from a cut. The UK property market has now produced three textbook examples in less than 20 years, and the April 2025 episode is the largest of them all.

HMRC transaction data shows that the period between January and March 2025 saw 339,630 UK residential transactions, 112,230 more than the 227,400 in the same quarter of 2024 (not seasonally adjusted), a 49% year-on-year surge. This was one of the largest single-quarter volume spikes in the SDLT era.

Conveyancers and solicitors reported record workloads throughout January to March. Some firms operated extended hours, and estate agents noted that properties were being snapped up within days of listing as buyers raced to exchange before the end of March.

The surge was concentrated in the £125,000 to £425,000 price bracket, precisely the range most affected by the threshold changes. Properties above £500,000 saw relatively normal transaction volumes, as the April changes had a smaller proportional impact at higher prices.

The Q2 2025 (April to June) data confirmed what analysts expected: a sharp fall in transaction volumes following the deadline rush. HMRC data shows UK residential transactions fell 9.9% compared to Q2 2024 (235,880 against 261,670), or 11.0% on a seasonally adjusted basis.

By Q3 2025, the market had broadly absorbed the higher rates. Lower interest rates (the Bank of England cut the base rate twice in H2 2025) offset some of the affordability impact and supported a gradual recovery in transaction volumes heading into early 2026.

First-time buyers faced the most significant change. The reduction in the FTB nil-rate band from £425,000 to £300,000 meant buyers purchasing between £300,001 and £500,000 now pay 5% SDLT on the amount above £300,000, up from 0% on the same band under the old rules.

For FTBs in London and the South East, where average first purchase prices are above £350,000, the change was most impactful. Data shows a measurable shift in FTB activity toward properties priced just below £300,000, consistent with buyers optimising their purchases to stay within the new nil-rate threshold.

Investors and second-home buyers faced not one deadline but two. The additional dwelling surcharge rose from 3% to 5% on 31 October 2024, and then the standard nil-rate band fell on 1 April 2025. Anyone who missed the first deadline still had a strong incentive to beat the second. The result was an 11% rise in higher rates additional dwelling (HRAD) transactions and a 33% rise in surcharge revenue year-on-year (HMRC Annual Stamp Tax Statistics, Table 3b).

The October 2024 rise could not be forestalled, because it took effect the day after the Budget announced it; only contracts already exchanged kept the 3% rate. What investors could still do was complete before April 2025 to avoid the lower nil-rate band. Industry analysts now report sustained suppression of BTL demand under the 5% surcharge, with yields harder to achieve at entry. See our buy-to-let stamp duty calculator for the current numbers.

Corporate purchases (limited-company structures used to hold rental property) were affected in the same way: a company letting the property commercially can claim relief from the 17% rate, and then pays the standard rates plus the 5% surcharge, just like an individual investor. The threshold change added the same incentive to complete before April. Compare structures with our limited company stamp duty calculator.

Despite predictions of a price correction, UK average house prices held up nationally. On the most recent figures the UK average was £272,611 in July 2026, up 1.4% on the year (UK HPI, July 2026). The national average conceals a widening regional split, and over the year to July 2026 that split turned into an outright fall in London.

When this article was first published it forecast that regional divergence was likely to persist and might accelerate through 2026. That forecast can now be settled against the outturn, and it understated what happened. Divergence did not merely persist, it changed sign. London was already falling on an annual basis by the end of 2025, and on the 12 months to July 2026 it is down 3.3%, while the North East is up 4.9% and the North West 4.4%. The gap between the strongest and weakest English regions is therefore no longer a difference between fast growth and slow growth, but between rising and falling prices. The structural driver is unchanged: buyers continue to favour regions where typical prices sit below, or comfortably within, the SDLT thresholds that tightened in April 2025.

The overall SDLT rate structure above £250,000 is largely unchanged; the impact of the April 2025 reversion is concentrated in the lower and middle price ranges where the nil-rate reductions bite hardest. Use our comparison calculator to see the full before-and-after picture for any purchase price.
