About Flat 1
Flat 1 is a semi-detached house in Thame (OX9 2DF). It has a recorded floor area of 60 m² (around 647 sq ft) and construction records dating it to 2003-2006. At 60 m² this is the 2nd smallest of 4 units on EPC record in the building, where floor areas span 46–69 m². The building's EPC ratings span C to B, with this unit at the bottom. On EPC score it ranks last in the building (79 versus a best of 84). The latest certificate (January 2012) shows a C (score 79), near the top of the C band. Earlier certificates rated it B (November 2008); the latest reading is one band lower. Between certificates, hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good. The latest certificate is from January 2012, so improvements made since then won't be reflected.
