About 43a
43a is a mid-terrace house in Swansea (SA1 1EF). It has a recorded floor area of 45 m² (around 484 sq ft), construction records dating it to before 1900 and council tax band A. At 45 m² this is the smallest unit on EPC record across the building (45–77 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 (48 versus a best of 80). The latest certificate (December 2025) shows an E (score 48), well below the UK norm with real room to improve. Earlier certificates rated it D (November 2014); the latest reading is one band lower. Between certificates, wall efficiency went from Very Poor to Good and lighting went from Very Poor to Very Good; while window efficiency dropped from Average to Poor and hot-water efficiency dropped from Average to Very Poor. Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition.
It lags the bulk of the postcode on energy efficiency (less efficient than 88% of similar EPCs).
