Overview

About 21 Byron Avenue

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

21 Byron Avenue is a three-bedroom semi-detached house in Watford (WD24 4HT). It has a recorded floor area of 87 m² (around 936 sq ft), construction records dating it to 1930-1949 and council tax band D. The latest certificate (April 2013) shows a D (score 59), a step below the typical UK home. The recommended improvements would lift it to B (score 83), a 2-band jump.

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 Byron Avenue is modelled from its 87 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in WD24 4HT. 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 21 Byron Avenue. 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 Byron Avenue was lodged in April 2013 at band D and expired in April 2023, 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 Byron Avenue. 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 34 schools and 30 stops listed are measured in a straight line from WD24 4HT, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
21 Byron Avenue 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.
