About 30 Harpenden Lane

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

It has a recorded floor area of 67 m² (around 721 sq ft), construction records dating it to 1930-1949 and council tax band E.

Between certificates, roof efficiency went from Very Poor to Poor and lighting went from Very Poor to Average; while wall efficiency dropped from Poor to Very Poor and hot-water efficiency dropped from Good to Average.

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 30 Harpenden Lane is modelled from its 67 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in AL3 7PB. 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. 2 sales are recorded for 30 Harpenden 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 30 Harpenden Lane was lodged in June 2015 at band F and expired in June 2025, so a new one is needed to sell or let. 3 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. 2 applications are matched to 30 Harpenden 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 15 months, which places each incident at an approximate point. The 5 schools and 30 stops listed are measured in a straight line from AL3 7PB, not by walking route.
Council tax band
30 Harpenden 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.
