Overview

About 17 High Street

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

17 High Street is a five-bedroom detached house in Colney Heath, St. Albans, St Albans (AL4 0NS). It has a recorded floor area of 96 m² (around 1032 sq ft), construction records dating it to before 1900 and council tax band E. The latest certificate (May 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 55). The latest certificate is from May 2011, 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.

At 96 m² the property is well over the postcode median (73 m² across 30 EPCs), placing it in the larger end of the local stock.

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 High Street is modelled from its 96 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in AL4 0NS. 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 17 High Street. 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 High Street was lodged in May 2011 at band E and expired in May 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. None is matched to 17 High Street. 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 16 months, which places each incident at an approximate point. The 6 schools and 30 stops listed are measured in a straight line from AL4 0NS, not by walking route.
Council tax band
17 High Street is in council tax band E. 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.
