The latest certificate (May 2022) shows a D (score 68), on the cusp of jumping into the C band. When first surveyed in July 2009 the rating was G, the property has climbed 3 bands since. Between certificates, wall efficiency went from Very Poor to Poor, roof efficiency went from Very Poor to Good and lighting went from Very Poor to Very Good; while hot-water efficiency dropped from Poor to Very Poor. The recommended improvements would push it to C (score 78). Main heating runs on electricity.
