257 Chertsey Crescent, New Addington, Croydon, CR0 0DJ

257 Chertsey Crescent is a three-bedroom end-of-terrace house in New Addington, Croydon, Croydon (CR0 0DJ). It has a recorded floor area of 63 m² (around 678 sq ft), construction records dating it to 1950-1966 and council tax band B. At 63 m² this is the 6th smallest of 7 units on EPC record in the building, where floor areas span 39–65 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 (54 versus a best of 79). The latest certificate (July 2014) shows an E (score 54), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 65). The latest certificate is from July 2014, so improvements made since then won't be reflected.

It hasn't traded since June 2007, a hold of 19 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. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £256,000 sits 92.5% above the 2007 sale of £133,000. On a £-per-square-foot basis, the last sale (£196/sq ft) was about 46.3% below the postcode norm.
