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 £699,000 sits 217.8% 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.
