About 66 High Street
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
66 High Street is a mid-terrace house in Cosham, Portsmouth, Portsmouth (PO6 3AJ). It has a recorded floor area of 33 m² (around 360 sq ft) and construction records dating it to 1950-1966. The latest certificate (December 2011) shows a D (score 67), on the cusp of jumping into the C band. When first surveyed in November 2010 the rating was E, the property has climbed 1 band since. Between certificates, window efficiency went from Poor to Good and lighting went from Average to Very Good; while hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good. The recommended improvements would push it to C (score 71). The latest certificate is from December 2011, so improvements made since then won't be reflected. At 33 m² this is the 2nd smallest of 32 units on EPC record in the building, where floor areas span 32–112 m². The building's EPC ratings span E to B across 32 units on file.
It hasn't traded since June 2011, a hold of 15 years that's notably long for the area. At 33 m² it sits well below the postcode median (50 m² across 31 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 74% of similar EPCs).
