About 15 Cottesbrooke Close
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
15 Cottesbrooke Close is a three-bedroom semi-detached house in Colnbrook, Slough, Slough (SL3 0JE). It has a recorded floor area of 110 m² (around 1184 sq ft), construction records dating it to 1930-1949 and council tax band D. It has already been extended once and our model flags further extension potential, a sign of buyer flexibility. The latest certificate (September 2015) shows a D (score 60), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 85), a 2-band jump. The latest certificate is from September 2015, so improvements made since then won't be reflected.
One planning record on file: an extension approved in 2001. Past consents include an extension, meaningful when judging how the property has evolved. Today's modelled estimate of £586,000 is 45.8% above the 2015 sale price. On a £-per-square-foot basis, the last sale (£340/sq ft) was about 54.7% above the typical sold price in the postcode.

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 15 Cottesbrooke Close is modelled from its 110 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SL3 0JE. 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 15 Cottesbrooke Close. 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 15 Cottesbrooke Close was lodged in September 2015 at band D and expired in September 2025, 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 15 Cottesbrooke Close. 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 9 schools and 30 stops listed are measured in a straight line from SL3 0JE, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 15 Cottesbrooke Close 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.
