About 18 Thornton Road
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
18 Thornton Road is a three-bedroom semi-detached house in Bromley (BR1 5AP). It has a recorded floor area of 106 m² (around 1141 sq ft), construction records dating it to 1930-1949 and council tax band D. The latest certificate (April 2013) shows a D (score 57), a step below the typical UK home. The recommended improvements would lift it to B (score 86), a 2-band jump. The latest certificate is from April 2013, so improvements made since then won't be reflected.
It hasn't traded since November 2007, a hold of 19 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. Today's modelled estimate of £508,000 sits 103.2% above the 2007 sale of £249,995. On a £-per-square-foot basis, the last sale (£219/sq ft) was about 15% below the postcode norm. One planning record on file: an extension approved in 2020. Past consents include an extension, meaningful when judging how the property has evolved.

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 18 Thornton Road is modelled from its 106 m² EPC floor area, its 1 recorded sale 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. 1 sale is recorded for 18 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 18 Thornton Road 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 18 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
- 18 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.
