Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for 21 High Street is modelled from its 118 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in HP18 9ST. It is an automated estimate, not a survey or mortgage valuation: condition, layout and improvements that aren't on record can move the real figure either way.
- Where sold prices come from
- Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 4 sales are recorded for 21 High Street. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC
- Energy Performance Certificates rate homes from A (most efficient) to G and last 10 years. The latest one for 21 High Street was lodged in January 2016 at band D and expired in January 2026, so a new one is needed to sell or let. Floor area, heating and insulation details on this page come from it.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 21 High 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 12 months, which places each incident at an approximate point. The 2 schools and 10 stops listed are measured in a straight line from HP18 9ST, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 21 High Street is in council tax band E. 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.
