About 21 Harold Street
21 Harold Street is a three-bedroom mid-terrace house in Grimsby (DN32 7LR). It has a recorded floor area of 88 m² (around 947 sq ft), construction records dating it to 1900-1929 and council tax band A. The latest certificate (May 2016) shows a D (score 60), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since September 2009. Between certificates, roof efficiency went from Very Poor to Good; while hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good. The recommended improvements would lift it to B (score 86), a 2-band jump. The latest certificate is from May 2016, so improvements made since then won't be reflected.
