About Opal House
Opal House is a semi-detached house in Milton Keynes (MK9 2EL). It has a recorded floor area of 70 m² (around 753 sq ft), construction records dating it to 2007-2011 and council tax band C. At 70 m² this is the largest unit on EPC record across Opal House (52–70 m²). The building's EPC ratings span C to B, with this unit at the top. The latest certificate (November 2020) returns a B (score 81), comfortably above the UK average. The rating has held steady at B across 2 certificates since August 2010. Between certificates, lighting went from Very Poor to Very Good.
