The Installers Directory

Choose a category

Three categories to start

No firms are listed yet: we only list a firm once it has passed our checks. More categories follow as homeowners ask for them.

How the Directory works

Six rules that don't move

1. Capped at three. No more than three firms per category in each postcode district. When a district is full, the next firm waits. No auction, and no paying to jump the queue.
2. Checked before listing. Every firm is checked against Companies House, the official registers, its insurance and how it protects your deposit before it appears. Anything that doesn't check out goes to Darren, an Engineer, who decides.
3. You contact them. They can never contact you through us, and we never tell a firm who has looked at its listing.
4. Your details stay yours. We never pass your details, your quote or your report to any firm.
5. A Red stays Red. A listed firm's quote is checked like anyone else's. Nobody can pay for a verdict, and each firm's quote-check record is shown on its listing.
6. Not a guarantee. A listing shows what we checked, and when. It doesn't guarantee a firm's work. You always choose for yourself.
