Heating Engineers in Cardiff
Compare free quotes from heating engineers in Cardiff, Roath, Canton, Cathays and Llandaff for boiler installation, servicing, repairs and radiators.
Victorian terraces and student streets
Cathays and Roath have one of the largest concentrations of student housing in Wales. Landlords need annual gas safety checks, and boilers in shared houses work hard. Many landlords book servicing and repairs over the summer, before the new academic year.
In Canton, Grangetown and Splott, the common job is a combi replacement or conversion in a two-storey terrace. Wales is wet, and homes with solid walls benefit from radiators sized carefully for each room.

Cardiff grew rapidly in the Victorian era, and its terraced streets still define Roath, Canton, Splott, Grangetown and Cathays. Llandaff and Whitchurch add larger period homes, Rhiwbina and Llanishen have inter-war semis, and Cardiff Bay brings modern waterside flats.

The local picture: Wales
Wales is wet and, in the valleys and uplands, cold in winter. Terraced valley towns and the coastal cities are largely on mains gas, but a large share of rural Welsh homes are off the gas grid and use oil, LPG or electric heating. Older stone terraces can be draughty and slow to warm up, so radiator sizing and controls matter.
Gas work is not a DIY job: by law it must be carried out by a Gas Safe registered engineer. Oil boilers are usually handled by OFTEC-registered technicians, and electrical work by a qualified electrician. How to check an engineer.
Why boiler quotes vary around Cardiff
Beyond the boiler itself, a few things specific to Cardiff can push a heating quote up or down:
- Rental timing: summer is busy for landlord work.
- Conversions: removing tanks and cylinders adds labour.
- Building rules: access and parking in the Bay affect timings.

Questions about hiring a heating engineer in Cardiff
Do gas safety rules apply in Wales?
Yes. Gas work must be carried out by a Gas Safe registered engineer, and landlords must arrange an annual gas safety check, as in England.
When should landlords book student house servicing?
Early summer is popular, between tenancies. Booking ahead helps, as engineers get busy before the autumn term.
Do Cardiff engineers cover Penarth and Caerphilly?
Many do. Your postcode decides which engineers receive your request.
