Overview

About 20 Buttermere Avenue

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

20 Buttermere Avenue is a three-bedroom semi-detached house in Dunstable (LU6 3PD). It has a recorded floor area of 120 m² (around 1292 sq ft), construction records dating it to 1950-1966 and council tax band D. The latest certificate (January 2016) shows an E (score 53), well below the UK norm with real room to improve. The rating has held steady at E across 4 certificates since November 2014. The recommended improvements would lift it to C (score 79), a 2-band jump. The latest certificate is from January 2016, so improvements made since then won't be reflected.
