About Chelsea House
Chelsea House is a two-bedroom mid-terrace house in Milton Keynes (MK9 2BS). It has a recorded floor area of 75 m² (around 807 sq ft) and construction records dating it to 1976-1982. The latest certificate (January 2020) returns a B (score 83), comfortably above the UK average. The rating has held steady at B across 2 certificates since November 2009. Between certificates, wall efficiency dropped from Good to Average and window efficiency dropped from Good to Average. At 75 m² this is the 42nd smallest of 47 units on EPC record in Chelsea House, where floor areas span 40–77 m². The building's EPC ratings span C to B, with this unit at the top.
Held since January 2008 — that's 18 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price.
