About 20 Gwallon Road
20 Gwallon Road is a semi-detached house in St Austell (PL25 3AA). It has a recorded floor area of 84 m² (around 904 sq ft), construction records dating it to 1930-1949 and council tax band B. The latest certificate (March 2016) shows an E (score 44), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since July 2014. Between certificates, wall efficiency went from Very Poor to Good and lighting went from Good to Very Good. The recommended improvements would lift it to C (score 76), a 2-band jump. Main heating runs on electricity. The latest certificate is from March 2016, so improvements made since then won't be reflected.
