4a, Brook Avenue, Wembley, HA9 8PH
About 4a
4a is a two-bedroom semi-detached house in Wembley (HA9 8PH). It has a recorded floor area of 42 m² (around 452 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (September 2021) shows a D (score 58), a step below the typical UK home. Earlier certificates rated it C (May 2009); the latest reading is one band lower. Between certificates, window efficiency went from Very Poor to Average and lighting went from Poor to Very Good; while wall efficiency dropped from Good to Poor. The recommended improvements would lift it to B (score 82), a 2-band jump.
It hasn't traded since September 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Across 1996–2009, sale prices on this property compounded at 9% per year. Today's modelled estimate of £372,000 sits 118.2% above the 2009 sale of £170,500. At 42 m² it sits well below the postcode median (69 m² across 69 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 74% of similar EPCs).
