What we do not do
We are an information platform — not an installer and not a consultancy. We do not provide technical advice, do not issue quotes and offer no guarantees. The decision to install a heat pump and the choice of installer remain entirely yours. We recommend comparing multiple quotes and verifying references via RVO.nl and the Chamber of Commerce (KvK).
