About 12 Celyn Grove

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

12 Celyn Grove is a four-bedroom semi-detached house in Cardiff (CF23 6SH). It has a recorded floor area of 163 m² (around 1755 sq ft), construction records dating it to 1930-1949 and council tax band G. The latest certificate (May 2025) shows a C (score 73).
