The latest certificate (May 2011) shows a D (score 63), on the cusp of jumping into the C band. The latest certificate is from May 2011, so improvements made since then won't be reflected.

Past consents include an extension, a garage conversion and a conservatory, meaningful when judging how the property has evolved. Last sold in August 2011, so it's been off the market for around 15 years.
