When first surveyed in October 2008 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 Poor to Good and hot-water efficiency went from Very Poor to Poor. The recommended improvements would push it to C (score 77). Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition.
