TrueDeed reports
Time to Sell methodology
Everything below is the complete recipe for the Time to Sell tracker. If a figure is on that page, this is exactly how it was made — and if no figure is there, this explains why not.
Data sources
Completions: HM Land Registry Price Paid Data transfer dates, trailing 12 months from the computation date. Listing dates: the date each property was first listed for sale on TrueDeed. Every figure is a median — never a mean — so single outliers cannot move it.
The matched-pair definition — confirmed matches only
One observation = one property we listed and then matched to its Land Registry sale, with the match confirmed — candidate or probable matches are never counted. Days to sell = Land Registry transfer date minus listing date. Because completion is the Land Registry transfer date, the number includes conveyancing: it is the honest end-to-end days a seller actually experiences, which is why our figures will typically read longerthan portal ‘time to under offer’ numbers. An under-offer status can be set optimistically, reset by relisting, and never checked against a completed sale; a transfer date is a public record.
Suppression threshold (disclosed, exact)
A figure publishes only when it is computed from at least 15 confirmed matched sales in the trailing 12 months. Below that, the cell is suppressed and shown as suppressed — never estimated, interpolated, or padded. This applies identically to the national figure and to every district; suppressed districts are counted on the report page but never ranked. Every cell that clears the threshold is published — none are hand-picked and none are held back.
Known lag: Land Registry registration
Completions typically take around 3 months to appear in Price Paid Data, so each edition is missing the most recent sales and a quarter’s figures firm up over time. Editions are recomputed rather than frozen on first publication for exactly this reason.
Periods and versioning
Editions are quarterly, named YYYY-Qn (e.g. 2026-Q2). Every row carries methodology_version (currently 1); if the computation ever changes, the version increments and this page documents the change — figures computed under different versions are never mixed silently.
