About 3a
3a is a three-bedroom semi-detached house in Thornaby, Stockton-On-Tees, Stockton On Tees (TS17 8GR). It has a recorded floor area of 95 m² (around 1023 sq ft), construction records dating it to 2007 onwards and council tax band C. The latest certificate (October 2019) shows a C (score 78), near the top of the C band. Earlier certificates rated it B (October 2009); the latest reading is one band lower. Between certificates, lighting went from Poor to Very Good; while roof efficiency dropped from Very Good to Good and hot-water efficiency dropped from Very Good to Good. The recommended improvements would push it to B (score 89).
It hasn't traded since March 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.
