Between certificates, lighting went from Very Poor to Very Good; while hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good.

The property has solar panels on record, all of which lower running costs and tend to lift resale appeal.

Untraded for 19 years, with the last transfer in March 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £257,000 is 36.7% above the 2007 sale price.
