Dorset House, Flat 2, 23 Dean Park Road, Bournemouth, BH1 1HX

Dorset House is a two-bedroom detached house in Bournemouth (BH1 1HX). It has a recorded floor area of 91 m² (around 980 sq ft), construction records dating it to 1967-1975 and council tax band C. At 91 m² this is the 4th smallest of 9 units on EPC record in Dorset House, where floor areas span 83–91 m². The building's EPC ratings span E to C, with this unit at the bottom. On EPC score it ranks last in the building (47 versus a best of 74). The latest certificate (March 2016) shows an E (score 47), well below the UK norm with real room to improve. Earlier certificates rated it D (December 2008); the latest reading is one band lower. Between certificates, main heating went from Average to Good; while hot-water efficiency dropped from Average to Poor. The recommended improvements would lift it to C (score 78), a 2-band jump. The latest certificate is from March 2016, so improvements made since then won't be reflected.

Untraded for 28 years, with the last transfer in May 1998. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £221,000 sits 225.2% above the 1998 sale of £67,950. On a £-per-square-foot basis, the last sale (£69/sq ft) was about 63.1% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 89% of similar EPCs).
