When UK households think about upgrading to a heat pump system, one of the first questions asked is:
Do heat pumps use more electricity than traditional boilers or heaters?
It’s a fair concern. With energy bills rising in Glasgow, Edinburgh, Manchester, Birmingham, and across the UK, no homeowner wants a heating system that increases costs instead of lowering them.

The reality? Heat pumps do use electricity but far more efficiently than gas or oil boilers. And with government support like the ECO4 heat pump grant UK, the savings can be significant. Let’s break it down.
Problem: Rising Confusion About Heat Pump Electricity Use
Across forums like Quora and Reddit, people ask the same thing:
- “Will my electricity bill skyrocket with a heat pump?”
- “Is a heat pump better at cooling or heating?”
- “How much additional electricity does a heat pump actually use?”
These questions highlight the uncertainty UK households face. On one hand, the government is pushing for heat pumps as part of its net zero target. On the other, homeowners—especially in colder areas like the Scottish Highlands—worry they’ll spend more keeping their homes warm.
How Heat Pumps Really Work?
A heat pump doesn’t generate heat the way a gas boiler does. Instead, it transfers heat from the outside air (or ground) into your home.
- Air Source Heat Pump (ASHP) – extracts heat from the air, even in freezing temperatures.
- Ground Source Heat Pump (GSHP) – extracts heat from the ground for stable, year-round performance.
For every 1 unit of electricity used, a heat pump delivers 3–4 units of heat energy. This efficiency is why the UK government backs them with ECO4 heating upgrades and funding schemes.
Does a Heat Pump Use More Electricity?
Yes – but here’s the difference:
- A gas boiler converts gas directly into heat, but wastes energy (average efficiency ~70–85%).
- A modern heat pump uses electricity to move heat instead of creating it. This means efficiency levels of 300–400% (COP 3–4).
Example:
If your heat pump uses 1kWh of electricity, it provides 3–4kWh of heating output. Even though the electricity usage may look higher, the total cost of heating is lower especially when combined with insulation and smart heating controls.
Why Heat Pumps Work in the UK?
- Scotland (Glasgow, Edinburgh, Aberdeen): Heat pumps paired with wall/loft insulation drastically reduce bills in older stone homes.
- Northern England (Manchester, Leeds, Newcastle): High gas prices make the ECO4 free central heating and heat pump grants a game-changer.
- Southern England (London, Bristol, Birmingham): Dense housing stock benefits from compact ASHP installations, cutting both bills and carbon footprints.
- Wales & Rural UK: Off-gas-grid households save most, replacing expensive oil heating with free renewable upgrades.

Common Myths About Heat Pumps – Busted
Myth 1: Heat pumps don’t work in cold UK weather
Truth: Air source heat pumps work efficiently down to –15°C, making them ideal for Scottish winters.
Myth 2: Heat pumps always increase electricity bills.
Truth: While electricity use rises, total heating bills fall because heat pumps deliver 3–4x more heat energy per kWh.
Myth 3: Heat pumps are only for new-build homes.
Truth: With ECO4, heat pumps can be retrofitted into older homes across the UK.
FAQs About Heat Pumps in the UK
Q1: Do heat pumps cost more to run than boilers?
No. Heat pumps are up to 3x more efficient. With ECO4 upgrades, most UK households see £400–£600 annual savings.
Q2: Are heat pumps noisy?
Modern systems are quiet (comparable to a fridge).
Q3: Can I get a free heat pump if I don’t claim benefits?
Yes. Through LA Flex, local councils can approve households on low incomes or with health conditions.
Q4: How long does installation take?
Usually 2–3 days, with minimal disruption.
Q5: Can I combine a heat pump with solar panels?
Yes and it’s one of the best ways to cut bills to nearly zero. Reliant Energy Solutions offers both under ECO4.
