Get started23a is a two-bedroom semi-detached house in Merton, London, London (SW19 4JD). It has a recorded floor area of 72 m² (around 775 sq ft), construction records dating it to 1900-1929 and council tax band D.

Between certificates, roof efficiency went from Very Poor to Poor. The recommended improvements would push it to C (score 78). The latest certificate is from June 2015, so improvements made since then won't be reflected.
