Overview

About 21 Dean Street

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

21 Dean Street is a three-bedroom mid-terrace house in Swindon (SN1 5EN). It has a recorded floor area of 89 m² (around 958 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (March 2016) shows an E (score 53), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 77), a 2-band jump. The latest certificate is from March 2016, so improvements made since then won't be reflected. Period features are noted in the property record.

Sold July 2021 for £198,000. Across the public record there are 4 sales, relatively high churn for a single property. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend. It lags the bulk of the postcode on energy efficiency (less efficient than 82% of similar EPCs). Across 1998–2021, sale prices on this property compounded at 5.5% per year. Today's modelled estimate of £240,000 is 21.2% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£207/sq ft) was about 72.8% above the typical sold price in the postcode.

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 Dean Street is modelled from its 89 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in SN1 5EN. 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. 4 sales are recorded for 21 Dean 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 21 Dean Street was lodged in March 2016 at band E and expired in March 2026, 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 21 Dean 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 17 months, which places each incident at an approximate point. The 33 schools and 30 stops listed are measured in a straight line from SN1 5EN, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
21 Dean Street is in council tax band B. 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.
