About 18 Heol Twrch

It has a recorded floor area of 69 m² (around 743 sq ft), construction records dating it to before 1900 and council tax band A. The property has solar panels on record, all of which lower running costs and tend to lift resale appeal. Other recorded features include a self-contained annexe and attached land beyond the plot. The latest certificate (March 2015) shows an E (score 45), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 74), a 2-band jump. Main heating runs on wood logs. The latest certificate is from March 2015, so improvements made since then won't be reflected.
