About 77a
77a is a mid-terrace house in Cardiff (CF5 4LE). It has a recorded floor area of 69 m² (around 743 sq ft) and construction records dating it to 1900-1929. At 69 m² this is the largest unit on EPC record across the building (30–69 m²). The building's EPC ratings span G to C across 8 units on file. The latest certificate (February 2026) shows an F (score 23), near the bottom of the EPC scale. The recommended improvements would lift it to C (score 73), a 3-band jump. Main heating runs on to be used only when there is no heating/hot. This certificate was lodged in the last six months, so the rating reflects current condition.
At 69 m² it's 15% larger than the typical home in the postcode (60 m² median across 7 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 86% of similar EPCs).
