Trencherfield Mill, Apartment 16, Heritage Way, Wigan, WN3 4DU

Trencherfield Mill is a two-bedroom mid-terrace house in Wigan (WN3 4DU). It has a recorded floor area of 75 m² (around 807 sq ft), construction records dating it to before 1900 and council tax band B. At 75 m² this is the 29th smallest of 50 units on EPC record in Trencherfield Mill, where floor areas span 40–111 m². The building's EPC ratings span E to B, with this unit at the bottom. The latest certificate (February 2022) shows an E (score 49), well below the UK norm with real room to improve. Earlier certificates rated it D (December 2008); the latest reading is one band lower. Between certificates, hot-water efficiency went from Very Poor to Poor and lighting went from Average to Very Good; while wall efficiency dropped from Good to Very Poor and window efficiency dropped from Good to Average. The recommended improvements would lift it to C (score 71), a 2-band jump. Main heating runs on electricity.

It hasn't traded since June 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs).
