How to read this page

Where every figure above comes from, how current it is and what it can't tell you.
How the estimate is made
We don't publish an estimate for 21 King William Street because there is no EPC to tell the model the home's size and specification. The full report sets its records against recent comparable sales in SN1 3LB.
Where sold prices come from
Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. No sale is recorded for 21 King William Street, which usually means it hasn't changed hands since 1995 or the sale was not for value. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
Reading the EPC
There is no Energy Performance Certificate on the public register for 21 King William Street. A valid EPC is needed to sell or let a home in England and Wales, and lasts 10 years.
Planning records
Planning applications are collected from local authority registers through PlanIt. None is matched to 21 King William Street. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
Area figures
Crime is police-recorded street-level data over the last 17 months, which places each incident at an approximate point. The 28 schools and 30 stops listed are measured in a straight line from SN1 3LB, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
21 King William Street is in council tax band B. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
