Get started1 Alexander Terrace is a three-bedroom semi-detached house in Box, Corsham, Corsham (SN13 8DY). It has a recorded floor area of 108 m² (around 1163 sq ft), construction records dating it to 1900-1929 and council tax band D. The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal. Other recorded features include notable views and a conservatory. The latest certificate (February 2026) shows a D (score 64), on the cusp of jumping into the C band. The rating has held steady at D across 3 certificates since September 2011. Between certificates, wall efficiency went from Very Poor to Poor and roof efficiency went from Good to Very Good; while lighting dropped from Average to Poor. The recommended improvements would push it to C (score 75). This certificate was lodged in the last six months, so the rating reflects current condition.
