Overview

About 21 Cotton Road

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

21 Cotton Road is a two-bedroom semi-detached house in Portsmouth (PO3 6FL). It has a recorded floor area of 73 m² (around 786 sq ft), construction records dating it to 2007-2011 and council tax band C. The latest certificate (June 2025) returns a high B (score 87), putting the home a stone's throw from an A rating. The rating has held steady at B across 3 certificates since February 2009. Between certificates, lighting went from Good to Very Good; while wall efficiency dropped from Very Good to Good and window efficiency dropped from Very Good to Good.

Untraded for 17 years, with the last transfer in June 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £272,000 sits 60% above the 2009 sale of £169,950. On a £-per-square-foot basis, the last sale (£216/sq ft) was about 28.2% below the postcode norm. One historical planning record sits against the property in 2009.
