1 Aylett Road is a three-bedroom end-of-terrace house in Isleworth (TW7 6NP). It has a recorded floor area of 77 m² (around 829 sq ft), construction records dating it to before 1900 and council tax band D. The latest certificate (July 2014) shows a D (score 59), a step below the typical UK home. When first surveyed in April 2009 the rating was F, the property has climbed 2 bands since. Between certificates, roof efficiency went from Poor to Good and lighting went from Average to Good; while wall efficiency dropped from Good to Very Poor and hot-water efficiency dropped from Very Good to Good. The recommended improvements would lift it to B (score 85), a 2-band jump. The latest certificate is from July 2014, so improvements made since then won't be reflected.
