Flat 1, 1 Sudrey Street, London, SE1 1PF

Flat 1 is an end-of-terrace house in London (SE1 1PF). It has a recorded floor area of 81 m² (around 869 sq ft), construction records dating it to 1996-2002 and council tax band E. The latest certificate (October 2009) shows an F (score 32), near the bottom of the EPC scale. Main heating runs on electricity. The latest certificate is from October 2009, so improvements made since then won't be reflected. At 81 m² this is the 3rd smallest of 5 units on EPC record in the building, where floor areas span 55–97 m². The building's EPC ratings span F to C, with this unit at the bottom. On EPC score it ranks last in the building (32 versus a best of 71).

Untraded for 19 years, with the last transfer in April 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 81 m² the property is well over the postcode median (57 m² across 33 EPCs), placing it in the larger end of the local stock. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £650,000 is 31.3% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£570/sq ft) was about 30.7% below the postcode norm.
