Is Fresh.Energy free to use?
Yes. Every calculator, guide and the Home Energy Score are free. We earn from clearly labelled advertising and, when you ask for quotes, from vetted installers — never from you.
Who will contact me if I request quotes?
Only if you tick the consent box: up to three vetted providers that serve your area for the services you picked. You can opt out at any time and we never sell your details to list brokers.
How accurate are the calculators?
They use the same building blocks professionals use — your bill, local sun hours, installed cost per watt, equipment efficiency and published emission factors — and every assumption is editable. Treat results as a planning range; a site survey sets the final number.
