All these marks represent organisations, schemes and codes that the government wants us to have which are intended to reassure you that we’re trustworthy and know what we’re doing.

But we invite you to judge for yourself. We promise to bend over backwards to prove to you that you were right to place your faith in us to give you a great renewable energy system to reduce your energy costs. If we do get things wrong, which we might as we’re only human, we’ll put it right without delay and ensure we learn from the experience.
