About 9 Dolphin Close
9 Dolphin Close is a three-bedroom semi-detached house in Plymouth (PL9 8RZ). It has a recorded floor area of 77 m² (around 829 sq ft), construction records dating it to 1967-1975 and council tax band C. The latest certificate (June 2026) shows an E (score 46), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since March 2009. Between certificates, roof efficiency went from Very Poor to Good, window efficiency went from Very Poor to Poor and hot-water efficiency went from Very Poor to Average; while lighting dropped from Average to Poor. The recommended improvements would lift it to C (score 71), a 2-band jump. Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition.
Untraded for 17 years, with the last transfer in September 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £222,000 sits 55.2% above the 2009 sale of £143,000. On a £-per-square-foot basis, the last sale (£173/sq ft) was about 27.7% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 75% of similar EPCs).
