About Flat 3
Flat 3 is a mid-terrace house in Rickmansworth (WD3 1AY). It has a recorded floor area of 47 m² (around 506 sq ft) and construction records dating it to 1930-1949.

The latest certificate (December 2015) shows a C (score 71). The recommended improvements would push it to B (score 81). Main heating runs on electricity.
