Flat 1, 9 Cecil Road, Hounslow, TW3 1NU

Flat 1 is an end-of-terrace house in Hounslow (TW3 1NU). It has a recorded floor area of 51 m² (around 549 sq ft), construction records dating it to before 1900 and council tax band B. At 51 m² this is the 2nd smallest of 5 units on EPC record in the building, where floor areas span 45–59 m². The building's EPC ratings span E to C, with this unit at the bottom. The latest certificate (March 2015) shows an E (score 49), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 78), a 2-band jump. The latest certificate is from March 2015, so improvements made since then won't be reflected.

It hasn't traded since August 1998, a hold of 28 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 £259,000 sits 292.4% above the 1998 sale of £66,000. On a £-per-square-foot basis, the last sale (£120/sq ft) was about 61.1% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 89% of similar EPCs).
