About Chelsea House
Chelsea House is a mid-terrace house in Milton Keynes (MK9 2BU). It has a recorded floor area of 45 m² (around 484 sq ft), construction records dating it to 2007-2011 and council tax band B. At 45 m² this is the 6th smallest of 48 units on EPC record in Chelsea House, where floor areas span 42–85 m². The building's EPC ratings span C to B, with this unit at the bottom. The latest certificate (July 2026) shows a C (score 78), near the top of the C band. Earlier certificates rated it B (June 2010); the latest reading is one band lower. Between certificates, window efficiency dropped from Good to Average and hot-water efficiency dropped from Good to Average. This certificate was lodged in the last six months, so the rating reflects current condition.
Untraded for 19 years, with the last transfer in October 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price.
