About 103a
103a is a mid-terrace house in Southsea (PO5 1ES). It has a recorded floor area of 50 m² (around 538 sq ft) and construction records dating it to 1900-1929. At 50 m² this is the 8th smallest of 38 units on EPC record in the building, where floor areas span 39–245 m². The building's EPC ratings span G to C, with this unit at the top. The latest certificate (January 2026) shows a C (score 72). When first surveyed in September 2011 the rating was D, the property has climbed 1 band since. Between certificates, lighting went from Very Poor to Very Good; while window efficiency dropped from Good to Average. This certificate was lodged in the last six months, so the rating reflects current condition.
It hasn't traded since April 1997, a hold of 29 years that's notably long for the area. 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 £131,000 sits 336.7% above the 1997 sale of £30,000. On a £-per-square-foot basis, the last sale (£56/sq ft) was about 58.7% below the postcode norm.
