UK house prices declined by 0.4% in December 2025, according to Nationwide Building Society’s monthly report released on January 2. This monthly drop resulted in an annual increase of just 0.6%, the weakest yearly gain since April 2024. The figures contrasted with economists’ predictions, who expected a 0.1% rise in December and 1.2% growth for the full year, signaling unexpected softness in the housing market at year-end.

December Decline Highlights Shifting UK Housing Market Dynamics

Nationwide’s Chief Economist, Robert Gardner, explained that the slowdown in annual house price growth partly reflects substantial gains in December 2024 combined with the recent monthly decline. Despite this, mortgage approvals remain near pre-pandemic levels, which continues to support steady buyer demand amid changing affordability trends. Gardner emphasized that price growth in 2025 lagged behind wage increases. At the same time, the recent reduction in mortgage rates has eased affordability pressures somewhat.

The average property price for the fourth quarter of 2025 stood at £273,077 ($367,561), varying significantly across regions. London prices rose by 0.7% year over year, reaching an average of £529,372, while northern England averaged £168,317. Northern Ireland recorded the strongest regional growth at 9.7%, buoyed by rising prices across the Irish border. On the other hand, eastern England experienced a price decline of 0.8%, marking the weakest regional performance nationwide.

Analyst Scenarios and Policy Factors Influencing Market Outlook

Elliott Jordan-Doak, an economist with Pantheon Macroeconomics, anticipates a housing market rebound in 2026. His outlook factors in the limited property tax rises introduced in Finance Minister Rachel Reeves’ budget on November 26, which targeted only the highest-value homes instead of broader tax hikes some buyers feared. Furthermore, the Bank of England’s decision to cut its main interest rate from 4.00% to 3.75% on December 18 is expected to improve affordability further and encourage market activity. Financial markets are pricing in one or two additional quarter-point rate cuts during 2026.

Gardner reaffirmed Nationwide’s forecast for annual house price growth of 2–4% in 2026, driven by declining financing costs and fiscal policy support, indicating cautious optimism for the year ahead.

Decline: Market Outlook and Next Steps

The sharp decline in December and the resulting slow annual growth demonstrate ongoing adjustment in the UK housing market after a period of solid price gains. While London and Northern Ireland have shown resilience, other regions like eastern England reveal uneven conditions. Nevertheless, lower mortgage rates combined with restrained property tax increases have improved affordability, likely supporting renewed demand as 2026 unfolds.

Investors and market watchers should observe forthcoming economic data and central bank policies closely, as these will influence the path of UK house prices following this recent decline.
