About Flat 1
Flat 1 is a semi-detached house in Thame (OX9 2DF). It has a recorded floor area of 62 m² (around 667 sq ft), construction records dating it to 2003-2006 and council tax band C.

The latest certificate (November 2014) shows a C (score 78), near the top of the C band. Earlier certificates rated it B (October 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.
