On EPC score it ranks first in the building (72 versus a worst of 33). The property has solar panels on record, all of which lower running costs and tend to lift resale appeal.

Between certificates, roof efficiency went from Average to Good, hot-water efficiency went from Average to Good and lighting went from Good to Very Good. The latest certificate is from July 2013, so improvements made since then won't be reflected.
