Overview

About 21 Bydemill Gardens

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

21 Bydemill Gardens is a three-bedroom detached house in Highworth, Swindon, Swindon (SN6 7BS). It has a recorded floor area of 131 m² (around 1410 sq ft), construction records dating it to 1967-1975 and council tax band E. The latest certificate (July 2016) shows an F (score 33), near the bottom of the EPC scale. Earlier certificates rated it C (January 2014); the latest reading is 3 bands lower. Between certificates, wall efficiency dropped from Good to Poor and roof efficiency dropped from Average to Very Poor. The recommended improvements would lift it to D (score 66), a 2-band jump. Main heating runs on oil. The latest certificate is from July 2016, so improvements made since then won't be reflected.

Today's modelled estimate of £437,000 sits 50.7% above the 2014 sale of £289,995. One planning record on file: an extension approved in 2014.

How to read this page

Valuation method in detail
How the estimate is made
The estimate for 21 Bydemill Gardens is modelled from its 131 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in SN6 7BS. 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 Bydemill Gardens. 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 Bydemill Gardens was lodged in July 2016 at band F and expired in July 2026, 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. 1 application is matched to 21 Bydemill Gardens. 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 4 schools and 30 stops listed are measured in a straight line from SN6 7BS, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
21 Bydemill Gardens 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.
