About 4 King William Street
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
4 King William Street is a two-bedroom mid-terrace house in Swindon (SN1 3LB). It has a recorded floor area of 81 m² (around 872 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (September 2020) shows a D (score 58), a step below the typical UK home. When first surveyed in August 2010 the rating was E, the property has climbed 1 band since. Between certificates, roof efficiency went from Very Poor to Good and lighting went from Average to Very Good; while wall efficiency dropped from Poor to Very Poor. The recommended improvements would lift it to B (score 82), a 2-band jump.
Held since July 1998 — that's 28 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. One planning application is currently pending a decision in 2026. The record references conservation-area consent, which constrain future alterations. Today's modelled estimate of £204,000 sits 292.3% above the 1998 sale of £52,000. On a £-per-square-foot basis, the last sale (£60/sq ft) was about 58.9% below the postcode norm.

- How the estimate is made
- The estimate for 4 King William Street is modelled from its 81 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SN1 3LB. 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 4 King William 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 4 King William Street was lodged in September 2020 at band D and is valid until September 2030. 2 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 4 King William 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.

- Council tax band
- 4 King William 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.
