142a, Bellegrove Road, Welling, DA16 3QR

142a is a detached house in Welling (DA16 3QR). It has a recorded floor area of 59 m² (around 634 sq ft), construction records dating it to 1950-1966 and council tax band C. The latest certificate (January 2009) shows an E (score 52), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 83), a 3-band jump. The latest certificate is from January 2009, so improvements made since then won't be reflected. At 59 m² this is the 16th smallest of 22 units on EPC record in the building, where floor areas span 33–75 m². The building's EPC ratings span G to B across 22 units on file.

It hasn't traded since March 1999, 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 £244,000 sits 225.3% above the 1999 sale of £75,000. On a £-per-square-foot basis, the last sale (£118/sq ft) was about 52.2% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 76% of similar EPCs).
