1b, Leigham Street, Plymouth, PL1 3BE

1b is a two-bedroom end-of-terrace house in Plymouth (PL1 3BE). It has a recorded floor area of 88 m² (around 947 sq ft) and construction records dating it to before 1900. It is a listed building, which means external alterations are tightly controlled but it may qualify for heritage tax reliefs. At 88 m² this is the 4th smallest of 6 units on EPC record in the building, where floor areas span 33–103 m². The building's EPC ratings span E to D, with this unit at the bottom. On EPC score it ranks last in the building (53 versus a best of 68). The latest certificate (June 2016) shows an E (score 53), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since March 2012. Between certificates, window efficiency went from Poor to Average and lighting went from Average to Very Good. The recommended improvements would lift it to C (score 76), a 2-band jump. The latest certificate is from June 2016, so improvements made since then won't be reflected.
