UK annual house price growth slows to 0.0% in March, weakest in two years

The ONS reported on 20 May that average UK house prices were flat over the year to March 2026 — annual growth of 0.0%, down from 1.7% and the weakest since April 2024. Much of the dip is a base effect: prices spiked a year earlier ahead of April 2025 stamp duty changes. For buyers, that means little urgency and room to negotiate; for sellers, it's a reminder to price realistically. This is a flat market, not a falling one.
