Carnegie House is an end-of-terrace house in Milton Keynes (MK9 2DA). It has a recorded floor area of 66 m² (around 710 sq ft), construction records dating it to 2007-2011 and council tax band C. At 66 m² this is the 27th smallest of 41 units on EPC record in Carnegie House, where floor areas span 44–82 m². The building's EPC ratings span C to B, with this unit at the bottom. The latest certificate (December 2025) shows a C (score 79), near the top of the C band. Earlier certificates rated it B (December 2012); 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.

It hasn't traded since August 2007, a hold of 19 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £162,000 sits 126.8% above the 2007 sale of £71,433. On a £-per-square-foot basis, the last sale (£101/sq ft) was about 53% below the postcode norm. At 66 m² it's 29.4% larger than the typical home in the postcode (51 m² median across 40 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 78% of similar EPCs).
