Air Source Heat Pump Cost vs Electric Heating
Compare air source heat pump costs with direct electric heating or storage heaters, including efficiency, system upgrades and grant eligibility checks.
Quick answer
How does an air source heat pump compare with direct electric heating?
Compared with direct electric heating, an air source heat pump can deliver much more heat per unit of electricity, but conversion cost can be higher if the home needs radiators and pipework.

| Factor | Air source heat pump | Direct electric heating |
|---|---|---|
| Efficiency | Often 3 to 4 units of heat per unit of electricity | About 1 unit of heat per unit of electricity |
| Install work | May need wet heating system upgrades | Often simpler to replace like for like |
| Comfort | Designed for steady whole-home heating | Can vary by room and charging pattern |
| Hot water | Usually needs a cylinder plan | May already use immersion or direct hot water |
| Best fit | Homes with high electric heating bills and practical upgrade routes | Small spaces where disruption must stay minimal |
When an air source heat pump makes sense
The case is stronger when the home has high electric heating bills, suitable insulation and a practical route for radiators, cylinder and outdoor unit.
High usage
The higher the electric heating demand, the more important air source heat pump efficiency becomes.
Whole-home comfort
A wet heating system can give steadier room temperatures than individual heaters.
Upgrade route
The home needs workable pipe routes, radiator positions and hot water storage.
What changes the quote
The biggest quote differences are usually radiators, pipework, hot water cylinder work, electrical supply and controls.
Wet system
Homes without radiators may need pipework and emitters added.
Electrical checks
The installer may need to check supply capacity, consumer unit and isolator requirements.
Disruption
Room-by-room work can be more involved than replacing storage heaters like for like.
What to compare before deciding
An air source heat pump can be much more efficient, but the installation scope has to make sense for the property and budget.
Net install cost
Compare the full price and final amount after any approved grant.
Expected efficiency
Ask for the seasonal performance assumption behind any running-cost estimate.
Room control
Check how bedrooms, living areas and hot water will be controlled day to day.
Common questions
Why can an air source heat pump beat direct electric heating?
Direct electric heating turns one unit of electricity into about one unit of heat. An air source heat pump can deliver several units of heat per unit of electricity when well designed.
Why is electric heating conversion sometimes expensive?
Homes without wet central heating may need radiators, pipework, controls and hot water cylinder work, so the installation is more than a unit swap.
Should storage heater tariffs be included?
Yes. Compare your current off-peak or storage-heater tariff with the tariff assumed for the air source heat pump running-cost estimate.
