Get started4 Barn Close is a five-bedroom detached house in Radlett (WD7 8LN). It has a recorded floor area of 226 m² (around 2428 sq ft), construction records dating it to 1967-1975 and council tax band G. The latest certificate (April 2010) shows an E (score 48), well below the UK norm with real room to improve. Earlier certificates rated it D (February 2010); the latest reading is one band lower. Between certificates, window efficiency went from Average to Good and lighting went from Average to Very Good; while roof efficiency dropped from Good to Average and hot-water efficiency dropped from Good to Poor. The recommended improvements would lift it to C (score 75), a 2-band jump. The latest certificate is from April 2010, so improvements made since then won't be reflected.
