About 27 St Stephens Mansions

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

27 St Stephens Mansions is a two-bedroom mid-terrace house in Cardiff (CF10 5LQ). It has a recorded floor area of 66 m² (around 710 sq ft), construction records dating it to 1991-1995 and council tax band E. The latest certificate (April 2026) shows a D (score 64), on the cusp of jumping into the C band. Earlier certificates rated it C (January 2012); the latest reading is one band lower. Between certificates, lighting went from Very Poor to Good; while window efficiency dropped from Good to Very Poor and hot-water efficiency dropped from Average to Very Poor. The recommended improvements would lift it to B (score 81), a 2-band jump. Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition. At 66 m² this is the 20th smallest of 64 units on EPC record in the building, where floor areas span 48–99 m². The building's EPC ratings span E to B across 64 units on file. Other recorded features include a balcony.
