New Central Heating Installation in Cardiff
A heating upgrade is more than a boiler swap. In Cardiff's older housing the radiators and pipework are usually the reason a house feels cold, not the boiler itself. Victorian terraces through Cathays, Roath and Canton lose heat through solid walls, so radiators sized decades ago for a different standard of insulation are often too small for the rooms they sit in.
What the survey checks
We work out how much heat each room actually needs, check every radiator against that, look at the condition of the pipework, and decide whether the system needs flushing before new equipment goes anywhere near it. Then we size the boiler to the property and your hot water demand rather than fitting the same model to every house on the street.
Boiler, or a bigger upgrade?
Sometimes a like-for-like boiler swap is genuinely all a Cardiff home needs. Other times it's better value to change radiators, add proper controls or move the system type while the work is being done anyway. We tell you which applies to your house, including when the honest answer is that a heat pump would suit the property better than another gas boiler.
Often done alongside a heating upgrade in Cardiff
- Loft Insulation in Cardiff — less heat lost means a smaller system that runs less
- External Wall Insulation in Cardiff — the biggest fix for a solid-wall terrace
- Air Source Heat Pumps in Cardiff — where coming off gas makes more sense than replacing it
Beyond the city, the same engineers work in Newport, Bridgend, Neath and Merthyr Tydfil. For how we approach heating work anywhere in the UK, see our Complete Heating System Upgrades page.
