Get startedOld Barn Cottage is a detached house in Affpuddle, Dorchester, Dorchester (DT2 7HH). It has a recorded floor area of 219 m² (around 2357 sq ft), construction records dating it to before 1900 and council tax band G. The latest certificate (November 2015) shows an E (score 47), well below the UK norm with real room to improve. Earlier certificates rated it D (October 2009); the latest reading is one band lower. Between certificates, lighting went from Average to Good; while wall efficiency dropped from Average to Very Poor and roof efficiency dropped from Very Good to Good. The recommended improvements would lift it to C (score 77), a 2-band jump. Main heating runs on oil. The latest certificate is from November 2015, so improvements made since then won't be reflected.
