Heat Pump vs Gas Boiler: What Should Homeowners Compare?
A practical guide comparing heat pumps and gas boilers, including running costs, system design, radiators, grant support and when each route makes sense.
The comparison should not start and end with the unit
A gas boiler and a heat pump are not just two boxes doing the same job in the same way. A heat pump needs the rest of the system to be designed around lower temperatures, which is why survey work matters much more.
That does not mean a heat pump is wrong for the home. It means the comparison should include emitters, controls, hot water strategy and long-term running behaviour, not just the appliance cost.
What homeowners usually care about most
For many homeowners, the key questions are cost after grant, likely running costs, whether the radiators will work and how disruptive the installation will be.
A good online estimate can help with the first part. The survey is what confirms the rest.
- Installed cost after grant support
- Running costs and controls strategy
- Radiator suitability and flow temperatures
- How much design work the home really needs
When the heat pump route becomes clearer
Heat pumps tend to make the most sense when the homeowner wants a longer-term system, realistic grant support, a cleaner comfort profile and a more deliberate design process.
If that sounds like the direction you are considering, start with the estimate tool and then move into survey if the early numbers feel sensible.

Often yes, but the answer depends on the home rather than the old boiler size. The estimate gives a first guide, while the survey confirms heat loss, emitters and the final design route.
