About 9 Thornton Road
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
9 Thornton Road is a four-bedroom semi-detached house in Bromley (BR1 5AP). It has a recorded floor area of 143 m² (around 1539 sq ft), construction records dating it to 1930-1949 and council tax band D. The latest certificate (October 2025) shows a C (score 71). Our model identifies extension potential, subject to local planning policy. The home occupies a cul-de-sac position.
It hasn't traded since May 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 2008–2008, sale prices on this property compounded at 14.9% per year. Today's modelled estimate of £658,000 sits 110.2% above the 2008 sale of £313,000. On a £-per-square-foot basis, the last sale (£203/sq ft) was about 21.3% below the postcode norm. One planning record on file: an extension approved in 2008. Past consents include an extension, meaningful when judging how the property has evolved. At 143 m² it's 24.3% larger than the typical home in the postcode (115 m² median across 17 EPCs). Its energy rating outperforms most of the postcode (better than 76% of similar EPCs).

Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for 9 Thornton Road is modelled from its 143 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in BR1 5AP. 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 9 Thornton Road. 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 9 Thornton Road was lodged in October 2025 at band C and is valid until October 2035. 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 9 Thornton Road. 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 38 schools and 30 stops listed are measured in a straight line from BR1 5AP, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 9 Thornton Road 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.
