Get started13 Alexandra Cottages is a semi-detached house in Bromley, London, London (SE20 7JJ). It has a recorded floor area of 71 m² (around 764 sq ft) and construction records dating it to before 1900. The latest certificate (March 2021) shows an E (score 46), well below the UK norm with real room to improve. Earlier certificates rated it D (February 2011); the latest reading is one band lower. Between certificates, lighting went from Good to Very Good. The recommended improvements would lift it to C (score 74), a 2-band jump.
It hasn't traded since December 1998, a hold of 27 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £505,000 sits 381% above the 1998 sale of £105,000.

Past consents include an extension, a porch and new windows, meaningful when judging how the property has evolved.
