Trencherfield Mill, Apartment 23, Heritage Way, Wigan, WN3 4DU

Trencherfield Mill is a two-bedroom end-of-terrace house in Wigan (WN3 4DU). It has a recorded floor area of 68 m² (around 732 sq ft), construction records dating it to 2003-2006 and council tax band B. The latest certificate (April 2019) shows a D (score 64), on the cusp of jumping into the C band. When first surveyed in January 2009 the rating was E, the property has climbed 1 band since. Between certificates, hot-water efficiency went from Very Poor to Poor and lighting went from Very Poor to Poor; while window efficiency dropped from Good to Average. The recommended improvements would push it to C (score 72). Main heating runs on electricity. At 68 m² this is the 12th 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 across 50 units on file.

Today's modelled estimate of £112,000 is 21.1% below the 2008 sale of £141,950, running counter to the wider postcode trend, which makes the EPC and condition history especially worth a look. On a £-per-square-foot basis, the last sale (£194/sq ft) was about 25.2% above the typical sold price in the postcode. Untraded for 18 years, with the last transfer in September 2008. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price.
