About 12 Avalon Close
12 Avalon Close is a four-bedroom detached house in Watford (WD25 9TW). It has a recorded floor area of 274 m² (around 2949 sq ft), construction records dating it to 1950-1966 and council tax band F. The latest certificate (August 2016) shows an E (score 47), well below the UK norm with real room to improve. Earlier certificates rated it D (January 2016); the latest reading is one band lower.

The recommended improvements would lift it to C (score 77), a 2-band jump. The latest certificate is from August 2016, so improvements made since then won't be reflected.
