Evidence first. Then a few questions. Then honest planning numbers — not a callback form.

How we stay independent
HeatWise is not an installer. 10+ years in heating and renewables — underfloor, heat pumps, solar. The plan is built from the energy record and what you confirm. If you later want introductions, we only put you in touch with 1–3 local, vetted firms. You still choose. We don’t sell your details or push a product.
