Overview

About 20 Colonsay

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

20 Colonsay is a three-bedroom end-of-terrace house in Hemel Hempstead (HP3 8TZ). It has a recorded floor area of 85 m² (around 915 sq ft), construction records dating it to 1991-1995 and council tax band C. The latest certificate (August 2016) shows a C (score 71). The recommended improvements would push it to B (score 84). The latest certificate is from August 2016, so improvements made since then won't be reflected. Our model identifies extension potential, subject to local planning policy. The home occupies a cul-de-sac position.

4 planning records sit against the property, 4 approved, 0 refused. Past consents include a loft conversion, 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 20 Colonsay is modelled from its 85 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in HP3 8TZ. 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 20 Colonsay. 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 20 Colonsay was lodged in August 2016 at band C and expired in August 2026, 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. 4 applications are matched to 20 Colonsay. 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 8TZ, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
20 Colonsay is in council tax band C. 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.
