About 18 Cambridge Street
18 Cambridge Street is a three-bedroom mid-terrace house in Cardiff (CF11 7DH). It has a recorded floor area of 117 m² (around 1259 sq ft), construction records dating it to 1900-1929 and council tax band D. The latest certificate (December 2015) shows an F (score 38), near the bottom of the EPC scale. Earlier certificates rated it E (May 2015); the latest reading is one band lower. Between certificates, roof efficiency dropped from Good to Average and hot-water efficiency dropped from Average to Poor. The recommended improvements would lift it to B (score 85), a 4-band jump.
