This certificate was lodged in the last six months, so the rating reflects current condition.

It hasn't traded since April 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. On a £-per-square-foot basis, the last sale (£262/sq ft) was about 19.6% above the typical sold price in the postcode.
