Overview

About Trelawny House

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

Trelawny House is a four-bedroom semi-detached house in Cowfold, Horsham, Horsham (RH13 8BU). It has a recorded floor area of 175 m² (around 1887 sq ft), construction records dating it to before 1900 and council tax band F. The latest certificate (August 2010) shows an F (score 32), near the bottom of the EPC scale. The rating has held steady at F across 2 certificates since June 2009. Between certificates, hot-water efficiency went from Poor to Average. The recommended improvements would push it to E (score 45). The latest certificate is from August 2010, so improvements made since then won't be reflected. Period features are noted in the property record.

It hasn't traded since October 2000, a hold of 26 years that's notably long for the area. At 175 m² the property is well over the postcode median (101 m² across 4 EPCs), placing it in the larger end of the local stock. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Across 1999–2000, sale prices on this property compounded at 43.2% per year. Today's modelled estimate of £734,000 sits 133% above the 2000 sale of £315,000. On a £-per-square-foot basis, the last sale (£167/sq ft) was about 46.6% below the postcode norm. 18 planning records sit against the property, 11 approved, 7 refused. Past consents include new windows, an extension and a loft conversion, meaningful when judging how the property has evolved. The record references listed-building consent and conservation-area consent, which constrain future alterations.

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 Trelawny House is modelled from its 175 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in RH13 8BU. 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 Trelawny House. 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 Trelawny House was lodged in August 2010 at band F and expired in August 2020, so a new one is needed to sell or let. 2 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. 18 applications are matched to Trelawny House. 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 22 stops listed are measured in a straight line from RH13 8BU, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
Trelawny House 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.
