About Marlborough House
Marlborough House is a detached house in Cardiff (CF10 1DE). It has a recorded floor area of 65 m² (around 700 sq ft), construction records dating it to before 1900 and council tax band E. At 65 m² this is the 4th smallest of 15 units on EPC record in Marlborough House, where floor areas span 26–90 m². The building's EPC ratings span G to C across 15 units on file. The latest certificate (November 2012) shows a D (score 64), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 80). The latest certificate is from November 2012, so improvements made since then won't be reflected.
