Frequently asked questions
Everything you need to know before getting started
Yes, completely free. There is no charge for seeing your estimates or for asking Sunmax for a quote, and no obligation to go ahead.
Estimates are generated live from the roof area you draw, your location and Sunmax's own equipment and pricing. A site survey may adjust the final price slightly, but they give you a reliable idea of what each system would cost.
No. You can browse and compare your estimates without sharing any contact details. When you are ready, shortlist up to three systems and Sunmax will follow up with a formal quote.
Estimates appear as soon as you finish drawing your roof. From entering your address to comparing systems typically takes under two minutes.
Your contact details are only shared with Sunmax, and only when you ask for a quote. We don't sell your data or add you to any marketing lists.
Sunmax lists the postcode areas it usually installs in, and we let you know as soon as you enter your address. If yours is outside that area you can still see estimates and request a quote, and Sunmax will confirm whether they can cover it.
