11 Harbour Point, Stuart Street, Cardiff, CF10 5BW

11 Harbour Point is a two-bedroom mid-terrace house in Cardiff (CF10 5BW). It has a recorded floor area of 61 m² (around 657 sq ft), construction records dating it to 1996-2002 and council tax band E. At 61 m² this is the 5th smallest of 12 units on EPC record in the building, where floor areas span 43–119 m². The building's EPC ratings span D to B, with this unit at the bottom. Other recorded features include a balcony. The latest certificate (September 2023) shows a D (score 65), on the cusp of jumping into the C band. Earlier certificates rated it B (February 2013); the latest reading is 2 bands lower. Between certificates, window efficiency dropped from Good to Average and hot-water efficiency dropped from Average to Very Poor. The recommended improvements would lift it to B (score 82), a 2-band jump. Main heating runs on electricity.

It hasn't traded since June 2007, a hold of 19 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. It lags the bulk of the postcode on energy efficiency (less efficient than 73% of similar EPCs).
