Early access in the United States. We are still building our directory for the United States. The profiles here show real public evidence from named sources, but coverage is limited and our checks are not yet as complete as on our UK site. Treat this as a preview, not a full picture.

Certifications

Trade certifications, licenses and registrations

What each certification actually means, how many contractors hold it in the public entries we track, and how to verify it before you hire. Every figure comes from named public sources. Nothing is self-declared to us.

Licenses required by law

Certification schemes

Counts reflect the public register entries and source listings we have collected and cross-referenced, from licenses required by law to voluntary schemes. They are not official membership totals. Always verify a specific contractor on the official register before hiring.
