Overview

About 18 Castle Street

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

18 Castle Street is a two-bedroom end-of-terrace house in Southampton (SO14 6HA). It has a recorded floor area of 86 m² (around 926 sq ft), construction records dating it to before 1900 and council tax band C. The latest certificate (December 2021) shows a D (score 56), a step below the typical UK home. Earlier certificates rated it C (August 2009); the latest reading is one band lower. Between certificates, lighting went from Poor to Very Good; while wall efficiency dropped from Good to Poor and roof efficiency dropped from Good to Average.
