About 17 Berthwin Street
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
17 Berthwin Street is a mid-terrace house in Cardiff (CF11 9JH). It has a recorded floor area of 147 m² (around 1582 sq ft), construction records dating it to before 1900 and council tax band G. The latest certificate (February 2015) shows an E (score 54), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 72), a 2-band jump. The latest certificate is from February 2015, so improvements made since then won't be reflected.
