About Heat Pump Math

Heat Pump Math is a free calculator and educational resource for anyone researching heat pump running costs in the UK. We provide transparent, data-driven estimates without selling installations or steering you to specific suppliers.

How we research

Articles are researched using official UK government data (Ofgem price caps, MCS standards, BEIS heat pump trials), industry bodies (Energy Saving Trust, Carbon Trust), and peer-reviewed field studies. Every factual claim cites a primary source. We do not rely on manufacturer marketing claims.

Editorial approach

Articles are AI-researched and human-reviewed. We use Claude (Anthropic) to draft guides based on primary sources, then verify numbers and update for policy changes. This is disclosed transparently because we believe AI tools can improve research quality when used responsibly with human oversight.

Independence

We do not accept paid placements in articles, affiliate links to installers, or manufacturer sponsorship. The calculator and guides are free to use. If we add monetization in future (e.g., ads), we will update this page to disclose it clearly.
