Flat 1, 52 Hamsterley Street, Darlington, DL3 6QE

Flat 1 is a one-bedroom detached house in Darlington (DL3 6QE). It has a recorded floor area of 50 m² (around 533 sq ft), construction records dating it to 1900-1929 and council tax band A. The latest certificate (May 2009) shows an E (score 54), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 62). The latest certificate is from May 2009, so improvements made since then won't be reflected.

Held since July 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £111,000 sits 106.5% above the 2009 sale of £53,750. At 50 m² it sits well below the postcode median (73 m² across 35 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 80% of similar EPCs).
