About 1a

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

1a is a four-bedroom detached house in Downley, High Wycombe, High Wycombe (HP13 5JZ). It has a recorded floor area of 168 m² (around 1808 sq ft), construction records dating it to 1930-1949 and council tax band E. The latest certificate (April 2013) shows a D (score 57), a step below the typical UK home. The rating has held steady at D across 2 certificates since June 2011. Between certificates, roof efficiency dropped from Good to Very Poor. The recommended improvements would push it to C (score 76). The latest certificate is from April 2013, so improvements made since then won't be reflected. Our model identifies extension potential, subject to local planning policy.
