Overview

About 21 The Green

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

21 The Green is a four-bedroom detached house in Brill, Aylesbury, Aylesbury (HP18 9RU). It has a recorded floor area of 131 m² (around 1410 sq ft), construction records dating it to before 1900 and council tax band F. The latest certificate (June 2015) shows an F (score 34), near the bottom of the EPC scale. The recommended improvements would lift it to C (score 77), a 3-band jump. Main heating runs on oil. The latest certificate is from June 2015, so improvements made since then won't be reflected.
