2b, Nibthwaite Road, Harrow, HA1 1TA

2b is a two-bedroom end-of-terrace house in Harrow (HA1 1TA). It has a recorded floor area of 51 m² (around 549 sq ft), construction records dating it to 2007 onwards and council tax band C. At 51 m² this is the 14th smallest of 49 units on EPC record in the building, where floor areas span 24–181 m². The building's EPC ratings span E to C, with this unit at the top. The property has solar panels on record, all of which lower running costs and tend to lift resale appeal. The latest certificate (October 2013) shows a C (score 77), near the top of the C band. When first surveyed in March 2010 the rating was D, the property has climbed 1 band since. Between certificates, wall efficiency went from Very Poor to Very Good and window efficiency went from Average to Good. The latest certificate is from October 2013, so improvements made since then won't be reflected.
