18 Derwent Close is a four-bedroom semi-detached house in Cottingham (HU16 4QR). It has a recorded floor area of 103 m² (around 1109 sq ft), construction records dating it to 1967-1975 and council tax band C. The latest certificate (August 2015) shows a D (score 65), on the cusp of jumping into the C band. The rating has held steady at D across 3 certificates since October 2009. Between certificates, roof efficiency went from Poor to Good and lighting went from Poor to Average; while wall efficiency dropped from Average to Poor and hot-water efficiency dropped from Very Good to Good. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from August 2015, so improvements made since then won't be reflected. Other recorded features include a conservatory.

At 103 m² the property is well over the postcode median (73 m² across 19 EPCs), placing it in the larger end of the local stock. One planning record on file: an extension approved in 2010. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved. Last sold in October 2015, so it's been off the market for around 11 years.
