About 25 Whalley Street
25 Whalley Street is a mid-terrace house in Blackburn (BB1 7NB). It has a recorded floor area of 78 m² (around 840 sq ft), construction records dating it to before 1900 and council tax band A. The latest certificate (December 2013) shows an F (score 31), near the bottom of the EPC scale. The rating has held steady at F across 3 certificates since August 2013. Between certificates, hot-water efficiency went from Very Poor to Average and lighting went from Very Poor to Average. The recommended improvements would lift it to B (score 87), a 4-band jump.
