Can You Have a Heat Pump Without Gas?
Yes, you can run a home with a heat pump without gas, and that is one of the main reasons people install one in the first place. Energy Saving Trust says heat pumps can generate around three units of heat for every unit of electricity they use, which is why an all-electric heating route can still be efficient even though electricity costs more per bought unit than gas.
For many households, “without gas” means the heating and hot water move to electricity, while cooking may or may not remain on gas depending on the property.
For the broader replacement question, read our can a heat pump replace a gas boiler, heat pump vs gas boiler guide, and electricity vs gas cost article.
What Changes in an All-Electric Home?
The main change is that heating and hot water are produced electrically through the heat pump rather than by burning gas on site. Energy Saving Trust says a typical air source heat pump costs around £11,000 before support, and part of the project cost reflects the move to a full electric heating layout with controls and hot water storage that suit the system.
The most common changes are:
- Gas boiler removed or retired.
- Hot water cylinder added if needed.
- Heating system redesigned for heat pump operation.
- Potential future pairing with solar or battery storage.
| Feature | Gas home | Heat pump without gas |
|---|---|---|
| Main heating fuel | Gas | Electricity |
| Hot water | Boiler-based | Heat pump plus cylinder in most cases |
| Future compatibility | Gas-dependent | Better aligned with all-electric upgrades |
An all-electric route often makes the most sense when the homeowner wants a longer-term heating strategy rather than another short-cycle boiler decision.
Is It Financially Sensible to Go Without Gas?
Often yes, especially when the property is suitable and the BUS grant is available. GOV.UK says the Boiler Upgrade Scheme can provide £7,500 towards an eligible air source heat pump installation, subject to eligibility, which changes the capital hurdle materially for homes moving away from gas-based heating.
The running-cost logic depends on useful heat, not raw unit price. Under this site’s April 2026 planning assumptions, electricity is 24.5p/kWh and gas is 7.4p/kWh, yet a heat pump at SPF 3.0 can still compete broadly with a 90% efficient gas boiler.
For the cost angle, see our heat pump cost guide and heat pump running costs article.
What Does This Mean in London, Surrey, and TW Homes?
In London, Surrey, and TW homes, going without gas is often strongest in family houses and semis where a well-designed heat pump can replace most or all of the old gas heating function. MCS reported more than 30,000 certified heat pump installations in the first half of 2025, which shows how normal all-electric heating is becoming in suitable retrofit homes.
Homes with solar are often even stronger candidates because the shift away from gas can be paired with some on-site electricity generation.
How Electromatic Can Help
If you want to know whether your home can move to a heat pump without gas, Electromatic can assess the heating system, hot water layout, and likely running-cost picture before you commit. That gives you a practical answer instead of a theoretical all-electric sales pitch.

Frequently Asked Questions
Can I remove gas completely if I install a heat pump?
Yes, for heating and hot water in many homes. Whether you also remove gas for cooking is a separate decision.
Does a heat pump need gas backup?
Not in most standard domestic systems. A properly designed heat pump should operate as the main heating source.
Is a heat pump without gas cheaper to run?
It can be broadly competitive or better in the right home, depending on system performance and tariff structure.
Can I combine an all-electric heat pump home with solar?
Yes, and that is often a strong long-term combination because solar helps offset part of the electricity used.
Is the BUS grant available if I remove gas heating?
Yes, subject to eligibility. The grant supports eligible heat pump installations, not the gas removal by itself.
