20 Dowson Close, Southwark, London, SE5 8AS

20 Dowson Close is a mid-terrace house in Southwark, London, London (SE5 8AS). It has a recorded floor area of 56 m² (around 603 sq ft), construction records dating it to 1967-1975 and council tax band B. At 56 m² this is the 5th smallest of 16 units on EPC record in the building, where floor areas span 40–81 m². The building's EPC ratings span D to C, with this unit at the top. The latest certificate (January 2026) shows a C (score 69), just inside the C band. When first surveyed in March 2009 the rating was D, the property has climbed 1 band since. Between certificates, window efficiency dropped from Good to Average. This certificate was lodged in the last six months, so the rating reflects current condition.

It hasn't traded since August 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 2001–2009, sale prices on this property compounded at 7.3% per year. Today's modelled estimate of £362,000 sits 106.9% above the 2009 sale of £175,000. On a £-per-square-foot basis, the last sale (£290/sq ft) was about 27.6% below the postcode norm.
