Between certificates, wall efficiency dropped from Poor to Very Poor and hot-water efficiency dropped from Good to Very Poor. The recommended improvements would lift it to B (score 85), a 2-band jump. Main heating runs on electricity. The latest certificate is from March 2016, so improvements made since then won't be reflected.
