The latest certificate (October 2008) shows an E (score 46), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 66).

Held since January 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales.
