12 Jefferson Avenue is a one-bedroom detached house in Bournemouth (BH1 4NX). It has a recorded floor area of 41 m² (around 441 sq ft), construction records dating it to 1900-1929 and council tax band A. At 41 m² this is the smallest unit on EPC record across the building (41–135 m²). The building's EPC ratings span E to C, with this unit at the bottom. The latest certificate (October 2015) shows an E (score 53), well below the UK norm with real room to improve. Earlier certificates rated it C (November 2014); the latest reading is 2 bands lower. Between certificates, wall efficiency dropped from Good to Poor and roof efficiency dropped from Average to Poor. The recommended improvements would lift it to C (score 72), a 2-band jump. The latest certificate is from October 2015, so improvements made since then won't be reflected.
