Get startedTrencherfield Mill is a one-bedroom end-of-terrace house in Wigan (WN3 4DU). It has a recorded floor area of 40 m² (around 431 sq ft), construction records dating it to 1900-1929 and council tax band A. At 40 m² this is the smallest unit on EPC record across Trencherfield Mill (40–111 m²). The building's EPC ratings span E to B, with this unit at the bottom. The latest certificate (January 2025) shows an E (score 42), well below the UK norm with real room to improve. Earlier certificates rated it C (April 2018); the latest reading is 2 bands lower. Between certificates, window efficiency went from Average to Good; while wall efficiency dropped from Good to Very Poor. The recommended improvements would lift it to C (score 70), a 2-band jump. Main heating runs on electricity.
Held since May 2008 — that's 18 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 40 m² it sits well below the postcode median (73 m² across 49 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs). On a £-per-square-foot basis, the last sale (£267/sq ft) was about 72.4% above the typical sold price in the postcode.
Recommended upgrades on file would lift this property by multiple EPC bands.
