Overview

About Denne Park House

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

Denne Park House is a three-bedroom property in Horsham (RH13 0AZ). It has a recorded floor area of 110 m² (around 1184 sq ft), construction records dating it to before 1900 and council tax band E. It is a listed building, which means external alterations are tightly controlled but it may qualify for heritage tax reliefs. Period features are noted in the property record. At 110 m² this is the 8th smallest of 11 units on EPC record in Denne Park House, where floor areas span 29–155 m². The building's EPC ratings span F to C across 11 units on file. The latest certificate (August 2025) shows a D (score 66), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 77). Main heating runs on oil.

Untraded for 17 years, with the last transfer in December 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 110 m² the property is well over the postcode median (83 m² across 10 EPCs), placing it in the larger end of the local stock. Across 1996–2009, sale prices on this property compounded at 5.6% per year. Today's modelled estimate of £399,000 sits 62.2% above the 2009 sale of £245,950.

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 Denne Park House is modelled from its 110 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in RH13 0AZ. 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 Denne Park 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 Denne Park House was lodged in August 2025 at band D and is valid until August 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. None is matched to Denne Park 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 15 schools and 30 stops listed are measured in a straight line from RH13 0AZ, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
Denne Park House is in council tax band E. 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.
