A heat pump doesn't burn fuel. Instead, it moves heat from the air outside into your home using electricity — the same way your fridge moves heat out of the food compartment. Even in winter, there's enough heat energy in outdoor air to warm a UK home efficiently.
For every 1 kWh of electricity it uses, a modern air source heat pump delivers 3–4 kWh of heat. That's why they can cut heating bills even though electricity costs more per unit than gas.
How they work in detail →Modern heat pumps operate efficiently down to −20°C. The UK rarely drops below −5°C, so they're well-suited to our climate.
Despite higher electricity unit costs, efficiency of 300–400% means most homes see meaningful savings versus a modern gas boiler.
As the UK electricity grid gets greener, heat pump emissions fall automatically — without any changes to your system.

5 questions about your home. Instant heat loss estimate, pump size, and running cost comparison. No personal details needed.
Understand how heat pumps work, whether your home is suitable, and what the installation process looks like — before speaking to anyone.
We show you MCS-certified installers who operate in your area. Click directly to their site — no middleman, no forms, no cold calls.
A qualified engineer will visit to do a full room-by-room heat loss calculation before any installation. This is required by MCS standards.
Heat pumps aren't right for every home right now. We'll tell you that — and we'll explain what might need to change if the answer is "not yet."

Heat pumps have a reputation problem driven by poor installations, not poor technology. Here's what the evidence actually shows.
The UK has one of the mildest winter climates in Europe. Norway and Sweden — far colder — have over 60% of homes on heat pumps. The UK climate is well-suited.
Poor design causes poor results — oversized systems short-cycle, undersized ones run constantly. A proper heat loss calculation prevents both. Always ask to see the numbers.
Modern low-temperature systems work well with larger radiators. Many homes need only minor radiator upgrades, not a full refurbishment. Your installer can advise based on your heat loss.
