23 Meridian Plaza, Bute Terrace, Cardiff, CF10 2FP

23 Meridian Plaza is a one-bedroom end-of-terrace house in Cardiff (CF10 2FP). It has a recorded floor area of 48 m² (around 517 sq ft), construction records dating it to 2007 onwards and council tax band D. The latest certificate (October 2018) shows a C (score 73). When first surveyed in January 2009 the rating was D, the property has climbed 1 band since. Between certificates, hot-water efficiency went from Very Poor to Poor and lighting went from Average to Very Good. Main heating runs on electricity. The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal. Other recorded features include a balcony. At 48 m² this is the 44th smallest of 56 units on EPC record in the building, where floor areas span 30–85 m². The building's EPC ratings span D to B across 56 units on file.

Untraded for 17 years, with the last transfer in March 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. It lags the bulk of the postcode on energy efficiency (less efficient than 73% of similar EPCs).
