28 Royal Sovereign Apartments is a two-bedroom end-of-terrace house in Pentrechwyth, Swansea, Swansea (SA1 7FH). It has a recorded floor area of 60 m² (around 646 sq ft), construction records dating it to 2007-2011 and council tax band D. At 60 m² this is the 25th smallest of 32 units on EPC record in the building, where floor areas span 36–80 m². The building's EPC ratings span D to B, with this unit at the bottom. The latest certificate (February 2022) shows a D (score 61), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since April 2009. Between certificates, lighting went from Average to Very Good; while wall efficiency dropped from Very Good to Good and window efficiency dropped from Very Good to Good. The recommended improvements would push it to C (score 75). Main heating runs on electricity.

It hasn't traded since June 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 60 m² the property is well over the postcode median (38 m² across 31 EPCs), placing it in the larger end of the local stock. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement.
