91 Charlton Road, Harrow, HA3 9HR

91 Charlton Road is a three-bedroom semi-detached house in Harrow (HA3 9HR). It has a recorded floor area of 94 m² (around 1012 sq ft), construction records dating it to 1930-1949 and council tax band D. The latest certificate (April 2014) shows a D (score 63), on the cusp of jumping into the C band. When first surveyed in April 2011 the rating was E, the property has climbed 1 band since. Between certificates, wall efficiency went from Very Poor to Poor and hot-water efficiency went from Poor to Good; while roof efficiency dropped from Average to Poor and lighting dropped from Good to Poor. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from April 2014, so improvements made since then won't be reflected. Records show the property has been extended at some point in its history.

Held since January 1999 — that's 27 years off the open market, well above the local norm. 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 £573,000 sits 358.4% above the 1999 sale of £125,000. On a £-per-square-foot basis, the last sale (£124/sq ft) was about 58.6% below the postcode norm. One planning record on file: an extension approved in 2003. Past consents include an extension, meaningful when judging how the property has evolved.
