24 Dolphin Court, Dolphin Close, Surbiton, KT6 4DZ

24 Dolphin Court is a two-bedroom end-of-terrace house in Surbiton (KT6 4DZ). It has a recorded floor area of 62 m² (around 667 sq ft), construction records dating it to 1950-1966 and council tax band C. At 62 m² this is the smallest unit on EPC record across the building (62–69 m²). The building's EPC ratings span D to B across 24 units on file. The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal. The latest certificate (June 2019) shows a C (score 74). The rating has held steady at C across 3 certificates since March 2009. Between certificates, window efficiency dropped from Good to Average and hot-water efficiency dropped from Very Good to Good.

It hasn't traded since September 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. Across 1998–2007, sale prices on this property compounded at 11.9% per year. Today's modelled estimate of £425,000 sits 51.8% above the 2007 sale of £280,000. On a £-per-square-foot basis, the last sale (£420/sq ft) was about 18.2% above the typical sold price in the postcode.
