About 11a
11a is a three-bedroom semi-detached house in Liverpool (L23 0SU). It has a recorded floor area of 90 m² (around 969 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (October 2013) shows an E (score 50), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since February 2009. Between certificates, wall efficiency went from Very Poor to Poor, hot-water efficiency went from Poor to Average and main heating went from Average to Good; while roof efficiency dropped from Very Good to Good and window efficiency dropped from Good to Average. The recommended improvements would lift it to B (score 82), a 3-band jump. The latest certificate is from October 2013, so improvements made since then won't be reflected.
