Get startedFlat 1 is a mid-terrace house in London (SW6 4DU). It has a recorded floor area of 43 m² (around 463 sq ft), construction records dating it to before 1900 and council tax band D. At 43 m² this is the largest unit on EPC record across the building (27–43 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 (41 versus a best of 70). The latest certificate (May 2025) shows an E (score 41), well below the UK norm with real room to improve. When first surveyed in March 2010 the rating was F, the property has climbed 1 band since. Between certificates, wall efficiency went from Very Poor to Good, window efficiency went from Very Poor to Good and lighting went from Poor to Very Good; while hot-water efficiency dropped from Average to Very Poor and main heating dropped from Poor to Very Poor. The recommended improvements would push it to D (score 68). Main heating runs on electricity.
Today's modelled estimate of £669,000 is 20.4% below the 2018 sale of £840,000, below the original sale price, which typically signals condition or completion-status changes worth verifying. On a £-per-square-foot basis, the last sale (£1,815/sq ft) was about 270.1% above the typical sold price in the postcode. It lags the bulk of the postcode on energy efficiency (less efficient than 79% of similar EPCs). Last sold in January 2018, so it's been off the market for around 8 years.
