List your business on Knowwatt
We're building an installer directory for UK homeowners who've already done the maths and are ready to get quotes. If you're MCS-certified, register your interest below.
How it works
Knowwatt helps homeowners model the costs, savings, and payback of solar panels, heat pumps, batteries, and insulation. Thousands of visitors use our calculators every month to decide whether to go ahead. Right now, when they're ready to find an installer, we send them to the MCS register.
We're building our own directory so those homeowners can find you directly — filtered by postcode, technology, and reviews. These aren't cold leads. They're people who've already run the numbers and decided to invest.
What you get
- A listing visible to homeowners in your coverage area who are actively looking for an installer
- Your company name, MCS accreditation number, services offered, coverage area, and a direct link to your website
- No middleman — homeowners contact you directly
- No lead fees, no commission on sales
What it costs
Nothing yet. We're gauging interest before we launch. If you register below, we'll be in touch when the directory goes live with pricing details. There's no commitment and no cost until then.
