About 21 Heslop Street
21 Heslop Street is a three-bedroom mid-terrace house in Thornaby, Stockton-On-Tees, Stockton On Tees (TS17 7HA). It has a recorded floor area of 98 m² (around 1055 sq ft), construction records dating it to 1900-1929 and council tax band A. The latest certificate (February 2016) shows an E (score 42), well below the UK norm with real room to improve. Earlier certificates rated it D (October 2013); the latest reading is one band lower. Between certificates, roof efficiency went from Average to Good; while hot-water efficiency dropped from Average to Poor and lighting dropped from Good to Very Poor. The recommended improvements would lift it to B (score 84), a 3-band jump. The latest certificate is from February 2016, so improvements made since then won't be reflected.
Held since June 1997 — that's 29 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £106,000 sits 292.6% above the 1997 sale of £27,000.
