About 7 Old Hill
7 Old Hill is a two-bedroom semi-detached house in Old St. Mellons, Cardiff, Cardiff (CF3 5SU). It has a recorded floor area of 79 m² (around 850 sq ft), construction records dating it to 1976-1982 and council tax band C. The latest certificate (September 2020) shows a D (score 59), a step below the typical UK home. The rating has held steady at D across 2 certificates since March 2009. Between certificates, lighting went from Very Poor to Very Good; while wall efficiency dropped from Good to Average and roof efficiency dropped from Average to Poor. The recommended improvements would lift it to B (score 84), a 2-band jump.
It hasn't traded since May 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £207,000 sits 80% above the 2009 sale of £115,000. At 79 m² it's 17.3% smaller than the typical home in the postcode (96 m² median across 8 EPCs).
