About Castle Court
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
Castle Court is a two-bedroom end-of-terrace house in Radyr, Cardiff, Cardiff (CF15 8RD). It has a recorded floor area of 57 m² (around 614 sq ft), construction records dating it to 1976-1982 and council tax band B. At 57 m² this is the 3rd smallest of 4 units on EPC record in Castle Court, where floor areas span 51–85 m². The building's EPC ratings span D to C, with this unit at the bottom. On EPC score it ranks last in the building (67 versus a best of 71). The latest certificate (July 2021) shows a D (score 67), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since January 2011. Between certificates, hot-water efficiency went from Average to Good, lighting went from Good to Very Good and main heating went from Poor to Good; while wall efficiency dropped from Good to Average and roof efficiency dropped from Average to Poor. The recommended improvements would push it to C (score 70).
It hasn't traded since December 2007, a hold of 19 years that's notably long for the area. Across the public record there are 4 sales, relatively high churn for a single property. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 57 m² it sits well below the postcode median (90 m² across 13 EPCs), making it one of the more compact homes locally. Across 1998–2007, sale prices on this property compounded at 13.4% per year. Today's modelled estimate of £148,000 is 24.4% above the 2007 sale price.
