Overview

About Wye House

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

Wye House is a three-bedroom detached house in High Wycombe (HP11 1DJ). It has a recorded floor area of 119 m² (around 1281 sq ft), construction records dating it to 1930-1949 and council tax band E. It has already been extended once and our model flags further extension potential, a sign of buyer flexibility. The latest certificate (August 2015) shows a D (score 55), a step below the typical UK home. The recommended improvements would lift it to B (score 82), a 2-band jump. The latest certificate is from August 2015, so improvements made since then won't be reflected.

3 planning records sit against the property, 3 approved, 0 refused. Past consents include an extension and a loft conversion, meaningful when judging how the property has evolved. At 119 m² it's 23.3% larger than the typical home in the postcode (97 m² median across 12 EPCs). Today's modelled estimate of £596,000 is 27.5% above the 2016 sale price. On a £-per-square-foot basis, the last sale (£365/sq ft) was about 15.3% above the typical sold price in the postcode. Last changed hands 10 years ago, in February 2016.

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 Wye House is modelled from its 119 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in HP11 1DJ. 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. 1 sale is recorded for Wye House. 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 Wye House was lodged in August 2015 at band D and expired in August 2025, 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. 3 applications are matched to Wye House. 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 15 months, which places each incident at an approximate point. The 21 schools and 30 stops listed are measured in a straight line from HP11 1DJ, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
Wye House 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.
