1a, Costain Grove, Stockton On Tees, TS20 1JW
About 1a
1a is a two-bedroom semi-detached house in Stockton On Tees (TS20 1JW). It has a recorded floor area of 33 m² (around 355 sq ft), construction records dating it to 1950-1966 and council tax band A. The property has an EV charger on record, all of which lower running costs and tend to lift resale appeal. Records show the property has been extended at some point in its history. The home occupies a cul-de-sac position. The latest certificate (May 2026) shows an E (score 53), well below the UK norm with real room to improve. The rating has held steady at E across 3 certificates since October 2013. Between certificates, wall efficiency went from Poor to Good, roof efficiency went from Average to Very Good and lighting went from Average to Good; while window efficiency dropped from Average to Poor and hot-water efficiency dropped from Good to Poor. The recommended improvements would lift it to C (score 80), a 2-band jump. Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition.
At 33 m² it sits well below the postcode median (65 m² across 21 EPCs), making it one of the more compact homes locally.
