Between certificates, wall efficiency went from Very Poor to Good, window efficiency went from Poor to Good and hot-water efficiency went from Very Poor to Very Good; while roof efficiency dropped from Average to Poor and lighting dropped from Average to Very Poor. The latest certificate is from March 2011, so improvements made since then won't be reflected.
