Overview

About 27 Thornden

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

27 Thornden is a three-bedroom detached house in Cowfold, Horsham, Horsham (RH13 8AG). It has a recorded floor area of 43 m² (around 463 sq ft), construction records dating it to 1950-1966 and council tax band F. The latest certificate (June 2014) shows an F (score 30), near the bottom of the EPC scale. The recommended improvements would lift it to C (score 73), a 3-band jump. Main heating runs on lpg. The latest certificate is from June 2014, so improvements made since then won't be reflected.

At 43 m² it sits well below the postcode median (119 m² across 12 EPCs), making it one of the more compact homes locally. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £820,000 sits 78.6% above the 2014 sale of £459,250.

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 27 Thornden is modelled from its 43 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in RH13 8AG. 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 27 Thornden. 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 27 Thornden was lodged in June 2014 at band F and expired in June 2024, 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. 2 applications are matched to 27 Thornden. 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 1 school and 23 stops listed are measured in a straight line from RH13 8AG, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
27 Thornden is in council tax band F. 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.
