How the estimate is made

The estimate for Penbury Farm is modelled from its 326 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in HP10 8PG. 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.

Overview

About Penbury Farm

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

Penbury Farm is a detached house in Penn, High Wycombe, High Wycombe (HP10 8PG). It has a recorded floor area of 326 m² (around 3509 sq ft) and construction records dating it to before 1900. The latest certificate (August 2014) shows an E (score 54), well below the UK norm with real room to improve. When first surveyed in December 2011 the rating was G, the property has climbed 2 bands since. Between certificates, roof efficiency went from Very Poor to Average, hot-water efficiency went from Poor to Average and lighting went from Very Poor to Poor; while window efficiency dropped from Good to Average. The recommended improvements would lift it to C (score 73), a 2-band jump. The latest certificate is from August 2014, so improvements made since then won't be reflected.

How to read this page

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 Penbury Farm is modelled from its 326 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in HP10 8PG. 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. No sale is recorded for Penbury Farm, which usually means it hasn't changed hands since 1995 or the sale was not for value. 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 Penbury Farm was lodged in August 2014 at band E and expired in August 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 Penbury Farm. 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 6 schools and 30 stops listed are measured in a straight line from HP10 8PG, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
