Get startedFlat 1 is a one-bedroom semi-detached house in High Wycombe (HP12 3AE). It has a recorded floor area of 48 m² (around 517 sq ft), construction records dating it to 1900-1929 and council tax band B. At 48 m² this is the 3rd smallest of 5 units on EPC record in the building, where floor areas span 41–52 m². The building's EPC ratings span E to D, with this unit at the top. The latest certificate (December 2025) shows a D (score 56), a step below the typical UK home. When first surveyed in December 2008 the rating was E, the property has climbed 1 band since. Between certificates, wall efficiency went from Very Poor to Poor, lighting went from Very Poor to Good and main heating went from Poor to Average; while window efficiency dropped from Good to Poor. The recommended improvements would push it to C (score 78). Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition.
