Get started16 Charlotte Grove is a two-bedroom detached house in Smallfield, Horley, Horley (RH6 9AR). It has a recorded floor area of 73 m² (around 786 sq ft), construction records dating it to 1976-1982 and council tax band E. The latest certificate (May 2014) shows a D (score 67), on the cusp of jumping into the C band. When first surveyed in April 2009 the rating was E, the property has climbed 1 band since. Between certificates, roof efficiency went from Average to Good, window efficiency went from Average to Good and hot-water efficiency went from Very Poor to Good. The recommended improvements would lift it to B (score 86), a 2-band jump. The latest certificate is from May 2014, so improvements made since then won't be reflected. The home occupies a cul-de-sac position.
