Directory FAQ
Common questions about the contractor directory and claiming your profile.
What is the Mainline Network?
The Mainline Network is a commercial groundworks contractor directory — a growing catalogue of groundworks, piling, civils and enabling works companies across the UK. Companies can claim their profiles to verify ownership and join the network.
Who is listed in the directory?
Commercial groundworks companies, piling contractors, civils contractors and related specialists who deliver packages for developers and principal contractors — not a consumer trades directory.
How do I claim my company profile?
Find your company in the directory, open the claim form, verify your email with a one-time code, then wait for Mainline review. Once approved, your profile is marked as claimed and you become a Mainline Network member.
Is there a fee to claim a profile?
No. Claiming confirms you own or represent the business. There is no payment and no subscription — just verified ownership.
What happens after my profile is approved?
Your listing shows as claimed. Approved contractors may become eligible for commercial opportunities as the network grows — with no obligation and no promises of work volume.
My company is not listed yet — what should I do?
Contact Mainline Groundworks and we can help get your business into the directory so you can claim your profile.
