13 Sovereign Mews, Pearson Street, Hackney, London, E2 8ER

13 Sovereign Mews is a two-bedroom detached house in Hackney, London, London (E2 8ER). It has a recorded floor area of 95 m² (around 1023 sq ft), construction records dating it to 1976-1982 and council tax band C. At 95 m² this is the smallest unit on EPC record across the building (95–118 m²). The building's EPC ratings span D to C, with this unit at the bottom. The latest certificate (September 2009) shows a D (score 62), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 76). The latest certificate is from September 2009, so improvements made since then won't be reflected.

Held since December 2009 — that's 16 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. Across 1998–2009, sale prices on this property compounded at 8.4% per year. Today's modelled estimate of £594,000 sits 52.3% above the 2009 sale of £390,000. It lags the bulk of the postcode on energy efficiency (less efficient than 80% of similar EPCs).
