About 18 Castle Avenue
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
18 Castle Avenue is a semi-detached house in Highcliffe, Christchurch, Christchurch (BH23 4LL). It has a recorded floor area of 103 m² (around 1105 sq ft), construction records dating it to 1950-1966 and council tax band D. The latest certificate (January 2010) shows an E (score 49), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 75), a 2-band jump.
