House prices in Northamptonshire were almost unchanged over the year to August 2026, according to the latest official UK House Price Index. Both of the local authority areas that cover the county recorded only a fractional annual rise, and both were slightly lower than in July.

In West Northamptonshire, which includes Northampton, the mix-adjusted average house price was £289,726 in August 2026. That was 0.2% higher than in August 2025, when the average stood at £289,196, and 0.6% lower than in July 2026, when it was £291,616.

In North Northamptonshire the average was £252,884. That was 0.1% higher than the August 2025 figure of £252,507, and 1.6% lower than in July 2026, when it was £257,078.

Those annual rates were softer than the wider picture. Across the East Midlands the average price was £241,955, up 0.5% on a year earlier. Across the United Kingdom it was £273,037, up 0.9%. West Northamptonshire remains clearly above the regional average. North Northamptonshire is also above it, but by a smaller margin.

The type of home made a difference. In West Northamptonshire, semi-detached houses averaged £282,970 and terraced houses £234,451, each 1.0% higher than a year earlier. Detached houses averaged £467,095, down 0.6% on the year. Flats and maisonettes averaged £139,615, down 2.1%.

The pattern in North Northamptonshire was similar. Semi-detached houses averaged £249,321, up 1.0%, and terraced houses £201,883, up 0.8%. Detached houses averaged £401,061, down 0.7%. Flats and maisonettes averaged £117,641, down 2.3%.

First-time buyers also saw little annual change. In West Northamptonshire they paid an average of £240,551 in August 2026, 0.6% higher than a year earlier. In North Northamptonshire the first-time buyer average was £217,161, up 0.5%. Former owner-occupiers paid £351,402 and £298,604 respectively, each 0.1% lower than in August 2025.

Local figures can move around from month to month because they rest on fewer transactions than the national index. The UK House Price Index itself advises looking at the trend over a year or longer, rather than a single monthly change. The August monthly falls, especially the 1.6% dip in North Northamptonshire, are therefore best read alongside the almost flat annual rates, not as a sudden shift in the local market. The August 2026 figures are also provisional and may be revised in later releases. They are not seasonally adjusted.
