58a, Chapel Street, Chorley, PR7 1BS

58a is a mid-terrace house in Chorley (PR7 1BS). It has a recorded floor area of 90 m² (around 969 sq ft), construction records dating it to 1930-1949 and council tax band A. At 90 m² this is the largest unit on EPC record across the building (32–90 m²). The building's EPC ratings span D to C, with this unit at the bottom. The latest certificate (December 2013) shows a D (score 67), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since July 2011. Between certificates, roof efficiency went from Very Poor to Poor; while wall efficiency dropped from Poor to Very Poor and lighting dropped from Good to Very Poor. The recommended improvements would lift it to B (score 81), a 2-band jump. The latest certificate is from December 2013, so improvements made since then won't be reflected.

At 90 m² the property is well over the postcode median (48 m² across 12 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 75% of similar EPCs). Last sold in July 2011, so it's been off the market for around 15 years.
