21 Daulston Road is a mid-terrace house in Portsmouth (PO1 5RN). It has a recorded floor area of 71 m² (around 764 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (August 2015) shows an E (score 52), well below the UK norm with real room to improve. When first surveyed in August 2013 the rating was F, the property has climbed 1 band since. Between certificates, wall efficiency went from Poor to Good, hot-water efficiency went from Very Poor to Good and main heating went from Very Poor to Good; while roof efficiency dropped from Average to Very Poor and window efficiency dropped from Good to Average. The recommended improvements would lift it to B (score 82), a 3-band jump. The latest certificate is from August 2015, so improvements made since then won't be reflected.
