Flat 3, 14 Ribchester Road, Wilpshire, Blackburn, BB1 9JH

Flat 3 is a two-bedroom end-of-terrace house in Wilpshire, Blackburn, Blackburn (BB1 9JH). It has a recorded floor area of 110 m² (around 1184 sq ft) and construction records dating it to before 1900. The latest certificate (June 2015) shows an F (score 33), near the bottom of the EPC scale. Earlier certificates rated it E (July 2010); the latest reading is one band lower. Between certificates, lighting went from Poor to Average; while hot-water efficiency dropped from Average to Poor. The recommended improvements would lift it to D (score 56), a 2-band jump. The latest certificate is from June 2015, so improvements made since then won't be reflected. At 110 m² this is the 3rd smallest of 4 units on EPC record in the building, where floor areas span 80–127 m². The building's EPC ratings span F to D, with this unit at the bottom. On EPC score it ranks last in the building (33 versus a best of 67).

It hasn't traded since April 1996, a hold of 30 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £148,000 sits 236.4% above the 1996 sale of £44,000. On a £-per-square-foot basis, the last sale (£37/sq ft) was about 75.6% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 89% of similar EPCs).
