Flat 1, 113 Derby Road, Southampton, SO14 0DR

Flat 1 is a three-bedroom end-of-terrace house in Southampton (SO14 0DR). It has a recorded floor area of 29 m² (around 312 sq ft), construction records dating it to 1900-1929 and council tax band A. At 29 m² this is the 2nd smallest of 3 units on EPC record in the building, where floor areas span 26–49 m². The building's EPC ratings span E to D, with this unit at the bottom. On EPC score it ranks last in the building (52 versus a best of 65). The latest certificate (January 2023) shows an E (score 52), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 75), a 2-band jump. Main heating runs on electricity.

Held since August 1999 — that's 27 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 29 m² it sits well below the postcode median (64 m² across 6 EPCs), making it one of the more compact homes locally. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £184,000 sits 130% above the 1999 sale of £80,000. On a £-per-square-foot basis, the last sale (£256/sq ft) was about 344.6% above the typical sold price in the postcode. One historical planning record sits against the property in 2008.
