Sales by price band in TW18
How the 44 recent recorded sales in TW18 split across price bands — the shape of the local market, not just its midpoint:
Bands computed over the recorded-sales sample above. A sample is not the whole market — see the price trend below for the wider context.
Price trend: TW18 in context
An outcode sample is small, so set it against the wider market. The UK House Price Index (UKHPI) tracks average prices and annual change for the local authority and region TW18 sits in:
| Area | Average price | Annual change | As of |
|---|---|---|---|
| Spelthorne (local authority) | £439,609 | -2.9% | Jul 2026 |
| South East (region) | £380,878 | +0.2% | Jul 2026 |
| England & Wales (national) | £288,279 | +1.2% | Jul 2026 |
UKHPI is a mix-adjusted index published with a ~2-month lag. A street-level (HPSSA) small-area median is available from ONS as a bulk download — not yet wired here, so we never fabricate it.
Indicative current area value in TW18
