Should I Switch to a Heat Pump in 2025? A Practical Guide for UK Homes

Gas boilers are being phased out — and heat pumps are rising fast as a cleaner, greener alternative. But are they right for your home? In this 2025 guide, we break down the pros, cons, costs, and common questions around switching from gas to heat pump heating in the UK.

What Is a Heat Pump and How Does It Work?

A heat pump works like a fridge in reverse — extracting heat from the outside air (even in cold weather) and using it to warm your home and hot water. There are air-source and ground-source versions, with air-source being more common and easier to install.

Heat Pump vs Boiler: What’s the Difference?

Here’s how the two compare in 2025:

Gas boilers use fossil fuels; heat pumps use electricity and ambient air.
Heat pumps are up to 300% more efficient — for every 1kWh used, you get 3kWh of heat.
Gas is cheaper per unit, but heat pumps can still lower overall bills with good insulation.
Heat pumps have higher upfront cost, but grants help offset this in 2025.

Is Your Home Suitable for a Heat Pump?

Heat pumps work best in well-insulated homes with space for outdoor units and water tanks. If your EPC rating is D or higher, or you’re planning insulation upgrades, you’re likely a good candidate.

Government Grants in 2025

Through the Boiler Upgrade Scheme (BUS), the government offers £7,500 toward heat pump installations. Low-income households may qualify for full funding via ECO4. The Krowd can help you check eligibility and apply instantly.
