7a is a mid-terrace house in Southwark, London, London (SE15 4JA). It has a recorded floor area of 63 m² (around 678 sq ft) and construction records dating it to 1900-1929. At 63 m² this is the 5th smallest of 16 units on EPC record in the building, where floor areas span 40–177 m². The building's EPC ratings span E to C, with this unit at the bottom. The latest certificate (June 2009) shows an E (score 52), well below the UK norm with real room to improve. Earlier certificates rated it D (March 2009); the latest reading is one band lower. Between certificates, hot-water efficiency went from Average to Good, lighting went from Average to Very Good and main heating went from Average to Good. The recommended improvements would lift it to C (score 72), a 2-band jump. The latest certificate is from June 2009, so improvements made since then won't be reflected.

It hasn't traded since May 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. At 63 m² it's 29.6% smaller than the typical home in the postcode (90 m² median across 18 EPCs). On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £585,000 sits 602.3% above the 1999 sale of £83,300.
