Heat Pumps vs Boilers: Which Heating System Is Right for Your Home?

Discover the Benefits of Heat Pumps and Boilers.

As the UK moves toward greener energy solutions, more homeowners are asking the same question: Should I stick with a traditional gas boiler or switch to a heat pump? We’re here to help you make an informed decision based on cost, efficiency, and sustainability.

What’s the Difference Between a Heat Pumps and Boilers?

Boilers (typically gas or oil) burn fuel to generate heat. They’ve been a staple in UK homes for decades and are known for their reliable and powerful performance, especially in colder months.

Heat Pumps (air source or ground source) transfer heat from the air or ground into your home. Rather than generating heat through combustion, they use electricity to move existing heat — making them highly efficient and environmentally friendly.

Which is More Efficient?

Heat Pumps can be up to 300% efficient, meaning they produce three units of heat for every one unit of electricity they consume.

Modern Boilers are generally around 90–95% efficient, but they still burn fossil fuels, which comes with higher emissions.

Winner: Heat Pumps — lower energy use and lower carbon emissions.

Heat Pumps VS Boilers Installation Cost

Boiler installation usually costs between £2,000–£4,000.

Heat pump installation typically ranges from £7,000–£14,000, depending on system type and property size.

But don’t forget: government grants like the Boiler Upgrade Scheme can give you up to £7,500 toward a heat pump in England and Wales.

Winner: Boilers — but heat pumps can offer bigger savings long-term.

Which Has Cheaper Running Costs?

Boilers are currently cheaper to run because gas is often less expensive than electricity per kWh in the UK.

Heat Pumps shine in well insulated homes and can dramatically cut bills in the long term, especially with solar panels or time-of-use electricity tariffs.

Draw: Depends on insulation, home size, and usage.

Which Has a Cleaner Environmental Impact

Boilers burn gas or oil, producing carbon dioxide and contributing to climate change.

Heat Pumps use electricity — and as the UK grid gets greener, so does your heating.

Winner: Heat Pumps — a much lower carbon footprint.

Heat Pumps and Boilers, Maintenance and Lifespan

Boilers need annual servicing and usually last 10–15 years.

Heat Pumps also benefit from annual maintenance but can last 15–20 years or more.

Winner: Heat Pumps, with fewer moving parts and longer lifespan.

Our Expert Recommendation

If you live in a well insulated home or plan to invest in energy efficiency upgrades, a heat pump could future proof your heating and cut your carbon footprint. Heat pumps use renewable energy sources, reduce your reliance on fossil fuels, and often qualify for government incentives, making them a smart long term investment.

However, if you need a cost effective solution now and aren’t quite ready to switch, a modern condensing boiler is still a solid and reliable choice, especially when professionally installed and serviced by a trusted team like ours at Hayward Heating.
