About 1b
1b is a detached house in Wembley (HA9 6DU). It has a recorded floor area of 21 m² (around 231 sq ft) and construction records dating it to 1900-1929. At 21 m² this is the 2nd smallest of 25 units on EPC record in the building, where floor areas span 21–148 m². The building's EPC ratings span F to C, with this unit at the top. The latest certificate (February 2010) shows a C (score 69), just inside the C band. When first surveyed in November 2008 the rating was E, the property has climbed 2 bands since. Between certificates, wall efficiency went from Very Poor to Good, roof efficiency went from Poor to Very Good and window efficiency went from Very Poor to Good; while hot-water efficiency dropped from Average to Very Poor. The latest certificate is from February 2010, so improvements made since then won't be reflected.
