If your boiler is nearing the end of its life, it's a natural moment to ask whether a heat pump is the better long-term choice. Here's an honest comparison of the two.
Efficiency
A modern gas boiler is efficient at burning gas, but it's still burning fuel. A heat pump moves heat from the outside air and can deliver around three units of heat per unit of electricity — far more heat per unit of energy.
Comfort
Gas boilers tend to deliver quick, intense bursts of heat. Heat pumps provide gentle, steady warmth throughout the day, which many homeowners find more comfortable once they're used to it.
Carbon emissions
A gas boiler produces carbon every time it runs. A heat pump runs on electricity, which is getting greener as the grid decarbonises — so its emissions fall over time and support the UK's net-zero goals.
Cost and grants
Upfront, a heat pump typically costs more than a like-for-like boiler — but the Boiler Upgrade Scheme grant changes that maths significantly, and for many suitable homes a standard installation can be fully funded.
- Boiler: lower upfront cost, ongoing fuel bills and carbon
- Heat pump: grant-supported install, high efficiency, lower carbon
Which is right for you?
If you value efficiency, lower carbon and a future-proof system — and your home is suitable — a heat pump is well worth considering, especially with grant support. Check your funding options with a quick property check.
