What the Mainline Network is

The Mainline Network sits alongside Mainline Groundworks delivery. It connects approved contractors with commercial opportunities while protecting quality for clients publishing work into the network.

  • Commercial platform

    A curated network connecting vetted groundworks and civils contractors with structured project opportunities — not a public trade directory.

  • Selective access

    Contractors apply with trade coverage, insurance and capability detail. Applications are reviewed before access to opportunities.

  • Matched opportunities

    Commercial packages are matched by trade, location and coverage so contractors engage on work that fits — without chasing unfiltered enquiries.

  • Client-ready delivery

    Developers and principal contractors gain a curated route to capable delivery partners with fewer unqualified responses on live packages.

How it works

Four steps from application to engaging on commercial packages that fit your trade and coverage.

  1. 01

    Apply to join

    Submit your company profile, trades, coverage areas and insurance baseline. Tell us where you deliver and what packages you support.

  2. 02

    Review & approval

    We assess commercial fit, insurance standards and delivery capability before approving network access. Not every application is accepted.

  3. 03

    Access opportunities

    Approved contractors receive matched commercial opportunities relevant to their trade and geography — ready for review and response.

  4. 04

    Engage on fit

    Pursue packages that match your capacity and programme. Structured scopes reduce wasted tendering and unqualified chasing.

Benefits for contractors

Structured commercial work matched to your trade and geography — without chasing unfiltered enquiries.

  • Commercial package access

    Opportunities reflect real groundworks, civils and enabling works packages — not anonymous consumer leads.

  • Trade and coverage matching

    Matching considers what you deliver and where you operate, so opportunity quality stays commercially useful.

  • Controlled distribution

    Access is limited to approved contractors. That protects opportunity quality for both you and clients publishing work.

  • Delivery partner relationships

    Work alongside Mainline on developer-led schemes with structured introductions based on trade, capability and coverage.

Benefits for developers and clients

Developers and principal contractors get a curated route to capable delivery partners — without opening packages to unqualified noise.

  • Curated capability

    Work with contractors who have already been reviewed for insurance, trade coverage and commercial delivery readiness.

  • Faster package coverage

    Reach relevant specialists without opening a public tender to unqualified or poorly matched respondents.

  • Delivery-aligned relationships

    The network sits alongside Mainline Groundworks delivery — built for programme, scope clarity and commercial accountability.

Network FAQ

Common questions about joining, opportunities and the contractor directory.

Is the Mainline Network a public directory?

No. It is a commercial platform for vetted groundworks and civils contractors. The contractor directory supports discovery, but network access and opportunities are selective — not open to every trade enquiry.

Who can join the network?

Commercial groundworks, civils and specialist subcontractors who deliver packages for developers, principal contractors and Mainline Groundworks projects. Applications are reviewed for insurance, coverage and commercial fit.

How are opportunities matched?

Matching uses trade capability, location coverage and package type. The aim is fewer wasted reviews and clearer commercial fit — for contractors and for clients publishing work into the network.

Can I claim my company profile?

Yes. If your business appears in the contractor directory, you can submit a claim request, verify your email and wait for Mainline review. Claiming confirms ownership — there is no payment or subscription.

What do clients get from the network?

Developers and principal contractors gain access to a curated delivery network with clearer capability matching, faster mobilisation options and fewer unqualified responses on live packages.
