Flat 2, 92 St Georges Square, London, SW1V 3QY

Flat 2 is a one-bedroom mid-terrace house in London (SW1V 3QY). It has a recorded floor area of 56 m² (around 603 sq ft), construction records dating it to before 1900 and council tax band F. At 56 m² this is the 2nd smallest of 7 units on EPC record in the building, where floor areas span 36–90 m². The building's EPC ratings span D to C, with this unit at the bottom. The latest certificate (February 2019) shows a D (score 67), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since February 2009. Between certificates, lighting went from Very Poor to Very Good. The recommended improvements would push it to C (score 75).

It hasn't traded since April 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 56 m² it's 26.3% smaller than the typical home in the postcode (76 m² median across 24 EPCs). Today's modelled estimate of £681,000 is 38.3% above the 2008 sale price.
