About 171b
171b is a semi-detached house in Hounslow (TW3 3TT). It has a recorded floor area of 36 m² (around 388 sq ft), construction records dating it to 1900-1929 and council tax band B. At 36 m² this is the 2nd smallest of 15 units on EPC record in the building, where floor areas span 27–76 m². The building's EPC ratings span E to B, with this unit at the bottom.

Earlier certificates rated it D (June 2012); the latest reading is one band lower. Between certificates, roof efficiency dropped from Good to Very Poor and lighting dropped from Very Good to Good. The recommended improvements would push it to D (score 61). The latest certificate is from August 2014, so improvements made since then won't be reflected.
