The COVID-19 Stamp Duty Holiday

Chancellor Rishi Sunak announced a temporary SDLT holiday in response to the pandemic, raising the residential nil-rate threshold from £125,000 to £500,000. Buyers saved up to £15,000, triggering an unprecedented surge in UK property transaction volumes.
1 July 2021 – 30 September 2021

The Tapered Transition Period

To avoid a severe cliff-edge in transaction completions, a tapered holiday took effect, stepping the nil-rate threshold down to £250,000 before returning to the original statutory baseline.

The "Mini-Budget" Threshold Increases

Chancellor Kwasi Kwarteng announced permanent increases to the SDLT thresholds under the "Growth Plan": the standard residential nil-rate band doubled from £125,000 to £250,000, and First-Time Buyer Relief was raised from £300,000 to £425,000 (with property eligibility capped at £625,000).

Autumn Statement: The 31 March 2025 Sunset Date

Chancellor Jeremy Hunt amended the legislation, transforming the "permanent" mini-budget cuts into a temporary relief measure that would sunset on 31 March 2025.
31 October 2024

Autumn Budget: Additional Property Surcharge Raised to 5%

Chancellor Rachel Reeves announced an immediate increase in the Higher Rates for Additional Dwellings (HRAD) from 3% to 5%. This applied to buy-to-let investments and second homes completing on or after 31 October 2024.
1 April 2025

The Reversion to Baseline Thresholds

The temporary cuts expired. The standard nil-rate threshold reverted to £125,000, and the First-Time Buyer nil-rate threshold reverted to £300,000 (with the maximum qualifying property price resetting to £500,000).
Present — 2026/27 Status Quo

Current Stable Regime & Devolved Divergence

The 2026/27 tax year operates under the unchanged April 2025 statutory thresholds. Property taxes in Scotland (LBTT, administered by Revenue Scotland with an 8% ADS) and Wales (LTT, administered by the Welsh Revenue Authority with a £225,000 nil-rate threshold) continue to operate under devolved legislation.
