17 Blenheim Drive is a four-bedroom semi-detached house in Filton, Bristol, Bristol (BS34 7AX). It has a recorded floor area of 108 m² (around 1163 sq ft), construction records dating it to 1950-1966 and council tax band B. The latest certificate (October 2014) shows an E (score 42), well below the UK norm with real room to improve. Earlier certificates rated it D (June 2010); the latest reading is one band lower. Between certificates, roof efficiency went from Poor to Good and window efficiency went from Average to Good; while hot-water efficiency dropped from Good to Poor and main heating dropped from Good to Average. The recommended improvements would lift it to C (score 72), a 2-band jump. Main heating runs on lpg. The latest certificate is from October 2014, 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 £329,000 sits 564.6% above the 1997 sale of £49,500. On a £-per-square-foot basis, the last sale (£43/sq ft) was about 81.1% below the postcode norm. At 108 m² it's 20.7% larger than the typical home in the postcode (90 m² median across 18 EPCs).
