Annual UK house price growth was 2.7% in the year to May 2026, according to the UK House Price Index (ONS UK HPI, May 2026). The figure is a provisional estimate, subject to revision as further transaction data is incorporated into the index.
On a monthly basis, average UK house prices rose by 0.3% between April and May 2026 (ONS UK HPI, May 2026). That movement was smaller than the 1.5% recorded across the same April-to-May window a year earlier.
Stamp Duty Land Tax (SDLT) changes were introduced in England and Northern Ireland on 1 April 2025, as noted in the report (ONS UK HPI, May 2026). The stronger 1.5% price movement a year earlier falls within the same window as that SDLT change, and the smaller 0.3% movement this year is measured against it.
What this means for your stamp duty
The 2.7% annual rise is the price backdrop for any purchase agreed in 2026 (ONS UK HPI, May 2026).
