Trencherfield Mill, Apartment 25, 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 70 m² (around 753 sq ft), construction records dating it to before 1900 and council tax band B. At 70 m² this is the 18th 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. On EPC score it ranks last in the building (39 versus a best of 83). The latest certificate (September 2020) shows an E (score 39), well below the UK norm with real room to improve. Earlier certificates rated it D (December 2009); the latest reading is one band lower. Between certificates, hot-water efficiency went from Very Poor to Average and lighting went from Poor to Very Good; while wall efficiency dropped from Good to 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.

Today's modelled estimate of £121,000 is 23.4% below the 2008 sale of £158,000, an unusual pattern given regional price growth and worth checking against the EPC condition. On a £-per-square-foot basis, the last sale (£210/sq ft) was about 35.4% above the typical sold price in the postcode. Untraded for 18 years, with the last transfer in May 2008. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs).
