Overview

About 21 Mountside

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

21 Mountside is a detached house in Guildford (GU2 4JD). It has a recorded floor area of 71 m² (around 764 sq ft), construction records dating it to 1967-1975 and council tax band E. The latest certificate (May 2010) shows an F (score 35), near the bottom of the EPC scale. The recommended improvements would lift it to D (score 58), a 2-band jump. The latest certificate is from May 2010, so improvements made since then won't be reflected.

Untraded for 29 years, with the last transfer in September 1997. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 71 m² it sits well below the postcode median (149 m² across 13 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 £630,000 sits 186.4% above the 1997 sale of £219,950. On a £-per-square-foot basis, the last sale (£288/sq ft) was about 38.8% below the postcode norm. One planning record on file: an extension approved in 2025. Past consents include an extension and solar panel installation, meaningful when judging how the property has evolved.

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 21 Mountside is modelled from its 71 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in GU2 4JD. 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 21 Mountside. 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 21 Mountside was lodged in May 2010 at band F and expired in May 2020, 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 21 Mountside. 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 16 months, which places each incident at an approximate point. The 16 schools and 30 stops listed are measured in a straight line from GU2 4JD, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
21 Mountside 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.
