The latest certificate (September 2011) shows a D (score 58), a step below the typical UK home. The recommended improvements would push it to C (score 72).

It hasn't traded since August 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 73 m² it's 21.2% larger than the typical home in the postcode (60 m² median across 52 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 73% of similar EPCs).
