Overview

About 21 Park Lane

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

21 Park Lane is a four-bedroom semi-detached house in Colney Heath, St. Albans, St Albans (AL4 0NR). It has a recorded floor area of 105 m² (around 1130 sq ft), construction records dating it to 1900-1929 and council tax band E. The latest certificate (September 2014) shows an E (score 48), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 80), a 2-band jump. The latest certificate is from September 2014, so improvements made since then won't be reflected. Other recorded features include notable views. Period features are noted in the property record. The home occupies a cul-de-sac position.

Today's modelled estimate of £698,000 sits 79% above the 2015 sale of £390,000. At 105 m² it's 18% larger than the typical home in the postcode (89 m² median across 17 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 88% of similar EPCs). Last sold in December 2015, so it's been off the market for around 11 years. One historical planning record sits against the property in 2022.

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 21 Park Lane is modelled from its 105 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in AL4 0NR. 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 21 Park 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 21 Park Lane was lodged in September 2014 at band E and expired in September 2024, 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 21 Park 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 16 months, which places each incident at an approximate point. The 7 schools and 30 stops listed are measured in a straight line from AL4 0NR, not by walking route.
Council tax band
21 Park Lane 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.
