19b, Barforth Road, Southwark, London, SE15 3PS

19b is a detached house in Southwark, London, London (SE15 3PS). It has a recorded floor area of 55 m² (around 595 sq ft), construction records dating it to before 1900 and council tax band C. The latest certificate (March 2009) shows a G (score 9), near the bottom of the EPC scale. Main heating runs on electricity. The latest certificate is from March 2009, so improvements made since then won't be reflected. At 55 m² this is the 12th smallest of 36 units on EPC record in the building, where floor areas span 39–195 m². The building's EPC ratings span G to C, with this unit at the bottom. On EPC score it ranks last in the building (9 versus a best of 73).

It hasn't traded since August 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 55 m² it sits well below the postcode median (84 m² across 35 EPCs), making it one of the more compact homes locally. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £381,000 sits 111.7% above the 2008 sale of £180,000.
