Overview

About Castle Keep

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

Castle Keep is a four-bedroom detached house in High Wycombe (HP11 1DY). It has a recorded floor area of 211 m² (around 2271 sq ft), construction records dating it to before 1900 and council tax band G. The latest certificate (March 2023) shows an E (score 53), well below the UK norm with real room to improve. Earlier certificates rated it D (December 2011); the latest reading is one band lower. Between certificates, roof efficiency dropped from Good to Very Poor. The recommended improvements would lift it to C (score 79), a 2-band jump. Other recorded features include a balcony and a conservatory. Period features are noted in the property record. Records show the property has been extended at some point in its history.

Across 1995–2025, sale prices on this property compounded at 5.5% per year. Today's modelled estimate of £1,085,000 is 10.7% below the 2025 sale of £1,215,000, an unusual pattern given regional price growth and worth checking against the EPC condition. On a £-per-square-foot basis, the last sale (£535/sq ft) was about 457.6% above the typical sold price in the postcode. It changed hands recently, sold June 2025 for £1,215,000. 8 planning records sit against the property, 3 approved, 0 refused. Past consents include an extension and solar panel installation, meaningful when judging how the property has evolved.

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 Castle Keep is modelled from its 211 m² EPC floor area, its 5 recorded sales and recent sales of comparable homes in HP11 1DY. 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. 5 sales are recorded for Castle Keep. 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 Castle Keep was lodged in March 2023 at band E and is valid until March 2033. 2 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. 8 applications are matched to Castle Keep. 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 22 schools and 30 stops listed are measured in a straight line from HP11 1DY, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
Castle Keep is in council tax band G. 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.
