Overview

About 18 Copperfields

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

18 Copperfields is a four-bedroom detached house in High Wycombe (HP12 4AN). It has a recorded floor area of 120 m² (around 1292 sq ft), construction records dating it to 1983-1990 and council tax band F. The latest certificate (March 2011) shows an E (score 52), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 66). The latest certificate is from March 2011, so improvements made since then won't be reflected.

At 120 m² the property is well over the postcode median (91 m² across 51 EPCs), placing it in the larger end of the local stock. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. One planning record on file: an extension approved in 2002. Past consents include an extension, meaningful when judging how the property has evolved. Across 1996–2017, sale prices on this property compounded at 6.7% per year. Today's modelled estimate of £588,000 is 25.1% above the 2017 sale price. On a £-per-square-foot basis, the last sale (£364/sq ft) was about 19.7% above the typical sold price in the postcode. Last sold in August 2017, so it's been off the market for around 9 years.

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 18 Copperfields is modelled from its 120 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in HP12 4AN. 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 18 Copperfields. 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 18 Copperfields was lodged in March 2011 at band E and expired in March 2021, 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 18 Copperfields. 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 12 schools and 30 stops listed are measured in a straight line from HP12 4AN, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
18 Copperfields 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.
