Why contractors join the marketplace

How construction opportunities are matched

Every construction lead is matched to your business using six factors, so the groundworks and civil engineering opportunities you see are relevant.

Construction leads FAQ

Common questions about construction leads, commercial opportunities and joining the contractor marketplace.

What are construction leads?

Construction leads are project opportunities from clients looking for contractors. On Mainline Groundworks they are commercial groundworks, civil engineering and infrastructure packages from developers and principal contractors across the UK, each listed with scope, location and project stage.

Are these commercial projects?

Yes. Opportunities come from developers, housebuilders and principal contractors and cover commercial groundworks leads, civil engineering leads, drainage, earthworks, RC frame, piling and Section 278/38/104 infrastructure — not one-off domestic jobs.

Do I pay to browse?

No. Creating a contractor account and browsing available construction leads is free. You only pay if you choose to unlock an individual project lead for direct client contact, and there is no subscription.

How are contractors matched to opportunities?

Construction leads are matched using your trade, location, coverage area, the package value you deliver, project stage and availability, so the groundworks and civil engineering opportunities you see are relevant to your business.

What trades can join?

Groundworks, civils, drainage, earthworks, RC frame, site clearance, enabling works, piling and Section 278/38/104 infrastructure contractors can all join. You filter subcontract opportunities by the trades you deliver.

Are projects nationwide?

Yes. Construction opportunities are published UK-wide, from London and the South East to the Midlands, the North and beyond. You set your coverage so you only see leads in your regions.

How often are opportunities added?

New commercial construction leads are added on an ongoing basis as developers and principal contractors publish packages. Enable email alerts in your account to be notified when relevant groundworks contracts and tenders go live.

Can I filter by location?

Yes. You can filter construction opportunities by region and postcode coverage so you only see projects within your operating area. See our service areas for where Mainline Groundworks operates.

Do I need insurance?

You need appropriate insurance to deliver commercial packages, including public liability and, where relevant, employer's liability. You can browse construction leads first and confirm cover during business verification.

Can sole traders join?

Yes. Sole traders and smaller subcontractors can create a free account, provided you can meet the insurance, health and safety and experience requirements for the commercial packages you pursue.

How do I get started?

Enter your email to create a free contractor account, verify your business, then browse commercial construction leads matched to your trade and coverage. There is no lengthy application and no obligation to unlock any lead.
