The latest certificate (October 2011) shows a D (score 61), on the cusp of jumping into the C band. When first surveyed in February 2009 the rating was E, the property has climbed 1 band since. Between certificates, roof efficiency went from Poor to Very Good and window efficiency went from Average to Good. The latest certificate is from October 2011, so improvements made since then won't be reflected.
