Get startedChanse House is a five-bedroom detached house in Fawley, Southampton, Southampton (SO45 1FQ). It has a recorded floor area of 233 m² (around 2508 sq ft), construction records dating it to 2003-2006 and council tax band F. The latest certificate (September 2015) shows a C (score 73). The rating has held steady at C across 2 certificates since August 2010. Between certificates, lighting dropped from Good to Very Poor. The recommended improvements would push it to B (score 91).
