Why Cardiff homeowners choose us for heat pumps.

We’ve been installing heat pumps across Wales for years – and in Cardiff, that means understanding everything from granite-walled terraces to modern detached homes and converted flats. Our teams are local, experienced, and trained to tailor each installation to the quirks of the property and its owners.
Our engineers are MCS-certified, and we only work with TrustMark-accredited contractors. What that means for you is peace of mind, quality work, and a home heated just the way you want it.
We’re also involved in local sustainability programmes where possible, helping make green heating not just more accessible, but more meaningful to the communities we’re part of.
And yes, that £350 discount? It’s still on the table for E.ON Next customers.

So, what exactly is an air source heat pump?
Think of it as a fridge in reverse. It takes the heat from the air outside – even when it’s chilly – and uses it to warm your home and your hot water. And because it runs on electricity (which can come from renewable sources), it cuts down your reliance on gas or oil.
Air source heat pumps work brilliantly with underfloor heating or modern radiators too, and if you’ve got solar panels, even better. You could power your heating with sunshine, even in a Welsh winter.
In terms of efficiency, for every 1 unit of electricity a heat pump uses, it can typically generate 3 to 4 units of heat. For comparison, a brand new boiler generates under one unit. So heat pumps are a potential boost to your energy efficiency, and maybe even your wallet over time, too.
