Flat 9, 35 Pont Street, London, SW1X 0BB

Flat 9 is a three-bedroom mid-terrace house in London (SW1X 0BB). It has a recorded floor area of 186 m² (around 2002 sq ft), construction records dating it to before 1900 and council tax band H. At 186 m² this is the largest unit on EPC record across the building (73–186 m²). The building's EPC ratings span E to C, with this unit at the bottom. On EPC score it ranks last in the building (46 versus a best of 80). The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal. Other recorded features include a balcony. The latest certificate (April 2018) shows an E (score 46), well below the UK norm with real room to improve. The rating has held steady at E across 3 certificates since September 2009. Between certificates, wall efficiency went from Very Poor to Good and lighting went from Very Poor to Very Good; while main heating dropped from Good to Very Poor. The recommended improvements would lift it to C (score 78), a 2-band jump. Main heating runs on electricity.

It hasn't traded since November 1996, a hold of 30 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 186 m² the property is well over the postcode median (123 m² across 21 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 86% of similar EPCs). Today's modelled estimate of £3,023,000 sits 235.9% above the 1996 sale of £900,000. On a £-per-square-foot basis, the last sale (£450/sq ft) was about 69.6% below the postcode norm. One historical planning record sits against the property in 2007.
