Get the right heat pump, fitted the right way

If you’re ready to install a heat pump, this section is for you.

It's important to pick a modern, efficient heat pump. It’s even more important to pick a brilliant installer. A great design delivers warm, even, low-cost heating. A poor design won’t, no matter how “premium” the heat pump is.

Picking a heat pump

Modern heat pumps are efficient, quiet and suitable for most UK homes. You don’t need to become an expert in every model; a few key points go a long way.

Prioritise modern refrigerants: R290 (propane) units are the newest generation. They offer strong efficiency, good cold-weather performance and the ability to run at higher flow temperatures.
Think about aftersales care: review warranty lengths and know who will attend in the even of a fault.
Power rating is important: the heat pump should be correctly sized from a room-by-room heat-loss calculation..

Beyond these fundamentals, the installer’s competence will have the biggest difference to performance.

Picking the right installer

The installer’s design and setup determine how efficiently your heat pump runs and what you pay to heat your home.

A well-designed system can run at around 3:1 efficiency, giving you £3 of heat for every £1 of electricity.
A poorly designed one may only achieve 2:1, giving you £2 of heat for the same £1.
For an average home, that difference is £300–£600 a year in running costs, every year.

That’s why picking a competent installer matters more than the brand of heat pump: their design and commissioning decide your comfort, efficiency and long-term bills.

At Warmur we've built our own network of top installers because their skills unlock long term value for our customers.

What to look out for at the quote stage

A clear quote helps you compare fairly and avoid surprise costs later. Lower prices often mean certain items are not included, for example:

fewer radiator upgrades
smaller hot-water cylinder
hard stand not included (you’re expected to arrange it)

None of these are necessarily wrong you just need to know what’s in and out so you’re comparing like-for-like. If it’s not written down, ask.

Also make sure:

Your installer is MCS certified and a member of RECC or HIES
They apply for the £7,500 BUS grant on your behalf
The £7,500 should already be deducted from the quote

Don’t get thrown off by common myths

A few outdated ideas regularly appear during the quote stage. You can safely ignore them:

“Hydrogen boilers are coming soon.” They aren’t; they will not play a role in home heating.
“You need external wall insulation first.” Most homes don’t. It’s expensive and not a requirement.
“You’ll need huge radiators everywhere.” Only where heat-loss calculations show it.
“Low flow temperatures won’t work here.” They will — with proper design.
