Educational tool only

Heat Pump Math provides general educational information about UK heat pump costs and efficiency. It is not professional advice. Do not rely on this calculator or articles as the sole basis for purchasing decisions. Consult an MCS-certified installer for a proper heat loss survey and quote specific to your home.

Estimates, not guarantees

The running cost calculator uses typical assumptions (standard heat demand per home size, average SCOP). Your actual costs will vary based on insulation quality, thermostat settings, weather, and how the system is commissioned. We do not guarantee savings or performance.

Data accuracy

We cite official UK sources (Ofgem, MCS, Energy Saving Trust) and update articles when policy changes. However, energy prices and regulations change frequently. Check Ofgem's website for current tariff caps and the Boiler Upgrade Scheme page for the latest grant amounts.

AI-assisted research

Articles are drafted using AI (Claude by Anthropic) to synthesize information from primary sources, then reviewed and updated by humans. We disclose this transparently. If you spot an error introduced by this process, please contact us.

No affiliation

Heat Pump Math is independent. We are not affiliated with heat pump manufacturers, installers, energy suppliers, or government schemes. We do not sell installations or receive commissions from referrals.
