1b, Blawith Road, Harrow, HA1 1TL
About 1b
1b is a one-bedroom semi-detached house in Harrow (HA1 1TL). It has a recorded floor area of 48 m² (around 517 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (February 2021) shows an E (score 44), well below the UK norm with real room to improve. When first surveyed in February 2017 the rating was G, the property has climbed 2 bands since. Between certificates, roof efficiency went from Very Poor to Average; while hot-water efficiency dropped from Good to Poor and lighting dropped from Very Good to Good. The recommended improvements would lift it to C (score 78), a 2-band jump. Main heating runs on electricity. At 48 m² this is the 8th smallest of 24 units on EPC record in the building, where floor areas span 39–180 m². The building's EPC ratings span E to C, with this unit at the bottom.
It hasn't traded since October 1996, a hold of 30 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 £217,000 sits 502.8% above the 1996 sale of £36,000. On a £-per-square-foot basis, the last sale (£70/sq ft) was about 77.7% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 78% of similar EPCs).
