Overview

About 17 Chambersbury Lane

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

17 Chambersbury Lane is a four-bedroom semi-detached house in Hemel Hempstead (HP3 8AY). It has a recorded floor area of 126 m² (around 1356 sq ft), construction records dating it to 1930-1949 and council tax band D. The latest certificate (January 2016) shows an E (score 49), well below the UK norm with real room to improve. Earlier certificates rated it D (March 2014); the latest reading is one band lower. Between certificates, window efficiency went from Average to Good; while roof efficiency dropped from Average to Very Poor and lighting dropped from Poor to Very Poor. The recommended improvements would lift it to B (score 84), a 3-band jump. The latest certificate is from January 2016, so improvements made since then won't be reflected. Records show the property has been extended at some point in its history.

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 2004. Past consents include an extension, meaningful when judging how the property has evolved. Across 2003–2021, sale prices on this property compounded at 5% per year. On a £-per-square-foot basis, the last sale (£402/sq ft) was about 50.3% above the typical sold price in the postcode. Most recent transfer: September 2021 at £545,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.

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 17 Chambersbury Lane is modelled from its 126 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in HP3 8AY. 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. 3 sales are recorded for 17 Chambersbury Lane. 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 17 Chambersbury Lane was lodged in January 2016 at band E and expired in January 2026, 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. 1 application is matched to 17 Chambersbury Lane. 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 18 schools and 30 stops listed are measured in a straight line from HP3 8AY, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
17 Chambersbury Lane is in council tax band D. 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.
