Overview

About 21 Allen Drive

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

21 Allen Drive is a five-bedroom detached house in Walters Ash, High Wycombe, High Wycombe (HP14 4SS). It has a recorded floor area of 172 m² (around 1851 sq ft), construction records dating it to 1950-1966 and council tax band F. The latest certificate (May 2014) shows a D (score 67), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since April 2009. Between certificates, wall efficiency went from Very Poor to Good, window efficiency went from Average to Good and lighting went from Very Poor to Good. The recommended improvements would lift it to B (score 82), a 2-band jump. The latest certificate is from May 2014, so improvements made since then won't be reflected.

Across 2010–2021, sale prices on this property compounded at 4.2% per year. Today's modelled estimate of £779,000 is 19.8% above the 2021 sale price. Sold August 2021 for £650,000.

Method

How to read this page

Where every figure above comes from, how current it is and what it can't tell you.
Valuation method in detail
How the estimate is made
The estimate for 21 Allen Drive is modelled from its 172 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in HP14 4SS. 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. 2 sales are recorded for 21 Allen Drive. 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 Allen Drive was lodged in May 2014 at band D and expired in May 2024, so a new one is needed to sell or let. 2 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. None is matched to 21 Allen Drive. 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 13 months, which places each incident at an approximate point. The 5 schools and 30 stops listed are measured in a straight line from HP14 4SS, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
21 Allen Drive is in council tax band F. 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.
