About 21 Allen Drive
21 Allen Drive is a five-bedroom detached house in Walters Ash, High Wycombe, High Wycombe (HP14 4SS). It has a recorded floor area of 172 m² (around 1851 sq ft), construction records dating it to 1950-1966 and council tax band F. The latest certificate (May 2014) shows a D (score 67), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since April 2009. Between certificates, wall efficiency went from Very Poor to Good, window efficiency went from Average to Good and lighting went from Very Poor to Good. The recommended improvements would lift it to B (score 82), a 2-band jump. The latest certificate is from May 2014, so improvements made since then won't be reflected.
