Radiator installation in Cardiff

Cardiff is the Welsh capital and largest city in Wales, a centre for government, media, sport and higher education, with a regenerated bay and dense Victorian terraced suburbs. We know the area well: we carry out radiator installation on behalf of homeowners, landlords, letting agents and property developers throughout Cardiff, from Roath, Cathays and Pontcanna.

Radiator installation in Cardiff should be simple. Give us a few details about what you need, and we will come back with a fixed price and our next available dates.

Local buildings are largely Victorian terraces, Edwardian semis, bay apartments and student lets, so each quote takes into account the building, parking and access and timing.

Many semis and terraces in Cardiff still have single-panel radiators that can be swapped for double-panel models in the same space for noticeably more heat.

Extensions and loft conversions around Cardiff often end up with one radiator too few, and adding a properly sized radiator is usually the simplest fix.

Decide whether you want new TRVs on every radiator being replaced
Check whether any work involves the boiler, which must be done by a Gas Safe registered engineer
Make sure the quote lists radiators, valves, pipework, inhibitor and balancing
