BRR in Cardiff: local prices, yields, and planning factors

Solid prices with a nationally recognised yield hotspot

Cardiff's average house price reached £273,000 in May 2026, up 2.9% year on year, while average rent hit £1,162 a month by June 2026, up 3.4% year on year. CF24 (Roath, Cathays, Splott) was named the UK's number one buy-to-let postcode hotspot for the first half of 2025 by Paragon Bank data, with an average yield of 8.9%, driven by proximity to the University Hospital of Wales, St David's Hospital, Cardiff Royal Infirmary and Cardiff University; Splott alone reaches around 9.3%, while CF10 (city centre, Cardiff Bay) offers a more modest 6.88%.

Dense Victorian terraces, with citywide HMO planning control

Cardiff has around 1,000 listed buildings spread across 27 conservation areas, including the Cathays Park Conservation Area, designated in 1975. Cathays, Roath and Plasnewydd carry a dense stock of Victorian and Edwardian terraces that have been heavily converted to student HMOs over time. Since 25 February 2016, Wales' Use Class C4 order has required planning permission for HMO conversion across Cardiff, with HMO Supplementary Planning Guidance adopted in 2019; properties that already had three or more tenants in place by 25 February 2016 received automatic implied C4 status, a useful cutoff date when assessing an existing HMO's planning history.

Licensing without a selective scheme, but with Rent Smart Wales

Cardiff runs additional licensing in Cathays, currently designated from 1 February 2023 for five years to around February 2028, while the Plasnewydd additional licensing scheme ran from 1 January 2021 to 31 December 2025 and had expired by the end of 2025 at time of writing, so its renewal status should be checked with the council. Unlike Bristol, Sheffield, Nottingham and Newcastle, Cardiff runs no selective licensing at all. Every landlord in Wales must also register with Rent Smart Wales (£37 for five years) and hold a personal licence or use a licensed agent, a nationwide requirement that should be built into a BRR refinance and exit plan from the outset.

Do I need Rent Smart Wales registration for a Cardiff BRR property?
