What is the heat pump vs boiler quiz?
A free five-question quiz that gives you a clear, numbers-backed recommendation on whether a heat pump or gas boiler makes more financial sense for your home.
How the quiz works
What the five questions cover, how your answers are scored and how we generate a personalised recommendation with estimated costs and savings.
Factors we consider
The key variables that determine whether a heat pump beats a boiler for your home, including insulation level, property size, current heating system and local gas prices.
Understanding your result
How to interpret the quiz recommendation, what the confidence score means, when the answer is clearly one or the other and when it depends on your priorities.
Cost comparison methodology
How we compare the total cost of ownership for a heat pump versus a boiler over 15 years, including installation, running costs, maintenance, grants and carbon pricing.
Heat pump suitability factors
The home characteristics that make a heat pump a strong choice, including good insulation, underfloor heating, off-gas properties and homes with space for an outdoor unit.
When a boiler still makes sense
Situations where replacing a gas boiler with another gas boiler is the better financial decision, at least for now, and what would change the calculation.
How grants affect the result
How the £7,500 BUS grant shifts the economics and at what point a heat pump becomes the clear winner once grant funding is applied.
Next steps after the quiz
What to do after you get your result, whether that means getting heat pump quotes, replacing your boiler or improving insulation first.
