Map your whole-house retrofit

A plan for your home — in five minutes.

Nine to eleven questions. We'll show you what's worth doing, in what order, roughly what it costs, and how much the BUS grant could cover. The survey comes later — this is the honest starting picture.

We'll ask about your property, your current heating, and what matters most to you. You can skip any question you're not sure about. At the end, you'll get a plan you can save, share, or email to yourself. No email required to see your plan.
