How we know this works

Built on over 2 billion datapoints, the model was tested against actual property sales it had never seen during training. Half our valuations landed within £13,558 of the final sale price. Three quarters were within 10%, and 93% within 20%. Nearly 1 in 5 were accurate to within 1%. Crucially, the model has no systematic lean in either direction — it's as likely to be slightly above as slightly below.

What goes into the estimate

Each valuation draws on over 250 data points: what comparable properties nearby actually sold for (assessed by size match, recency, and a blend of both), the property's floor area, build type, age, energy performance, and council tax band, plus how prices in the London region have moved. Land Registry records 20 transactions in this postcode, and an EPC is available for this property.

Kept current between data releases

House price data always lags slightly behind the real market. To close that gap, the estimate is forward-adjusted using the latest UK House Price Index for the London region, so the figure reflects current conditions rather than what things looked like six months ago.

This is an automated estimate produced by a statistical model and should not be used as a formal valuation. For mortgage, legal, or transactional purposes, please obtain a RICS-accredited valuation from a qualified surveyor.
