Official local housing data feed. House prices are provisional, not seasonally adjusted; rents use the Price Index of Private Rents. Local short-term estimates are variable. Country references use only the explicitly country-coded ctry object, never the local place object.

The whole authority area, not just the named city settlement.

Prices are in pounds at the time, not adjusted for inflation.

Average existing and new private rents; not a quote for a home currently advertised.

The table retains the full reviewed history when the chart is shortened. Preset ranges end at this measure’s latest published period. Yearly windows count published annual periods; monthly windows count months. Gaps are never filled with estimates.

Shown on this chart: £97,736 in August 1996; £590,816 in July 2026. 504.5% higher between these observations.

The line joins consecutive published observations.

Cash prices, before allowing for inflation. Changes do not show affordability without local earnings and household circumstances.

Data table and workings

Published UK House Price Index average price, all property types and all buyers, not seasonally adjusted. Entire series comes from the 2026-07 official full-file release, preserving its historical revisions and exact area codes. It is a mix-adjusted average, not the median price paid.

Prices are in pounds at the time, not adjusted for inflation.

Whole local authority area; not a typical home listing or the budget needed by a first-time buyer.

Provisional estimates can be revised. Historical boundaries follow the exact published source code; no old-code series has been relabelled.

The table retains the full reviewed history when the chart is shortened. Preset ranges end at this measure’s latest published period. Yearly windows count published annual periods; monthly windows count months. Gaps are never filled with estimates.
