Suppliers – register your interest

At Leighton Contractors, we believe in the importance of business relationships and welcome your interest in becoming a partner with us.

This starts with us understanding a little about your organisation, and the nature and scope of the goods and services you offer.

To allow us to do this, we’d like you to quickly and easily register an interest in supplying goods or services to Leighton Contractors via our Supplier Connexion portal.

Two of our large projects that are currently procuring goods and services have dedicated supplier registration portals.

The online questionnaire is in five simple parts and should take no more than 5-10 minutes to complete.

For technical support or queries about your registration please email

Please note that registering with Leighton Contractors via the general portal will typically result in your information being made available to all projects. You may use the project specific registration however, if you wish to register a specific interest with that project only.

Please note that registration of an interest in supplying goods and / or services to Leighton Contractors via the portal does not constitute any status of approval. Leighton Contractors will typically invite your company to formally register an Expression of Interest (EOI) for specific projects or packages and prior to, or as part of, the evaluation process undertake a ‘Prequalification’ process.

Thank you for your interest in partnering with Leighton Contractors.
