How To Become One Of Our Subcontractors

We do not currently have any requirements for subcontractors as our existing supplier base fulfils all of our requirements.

If you would like to apply to become one of our approved subcontractors in future, you will need to download and complete an initial Subcontractor Assessment Form.  You should note that due to the high volume of applications we receive, it may be several weeks before we can get back to you.

If you still want to apply, please refer to the Subcontract Approval Workflow for guidance on the process.  New suppliers should also refer to our Requirements for Suppliers, which contains extensive detail on the standards we expect of our supply chain partners including details of our Golden Rules, Operational Safety Standards and Site Rules.

Once you have been approved as a subcontractor, you will remain approved as long as there are satisfactory scores on subsequent performance reports and a good safety record. 

If it is longer than 18 months since you were approved and/or more than 12 months since we last placed an order with you, you may need to be re-assessed for approval before we can order from you again.  If this is the case, please see the Subcontract Re-assessment Workflow for guidance.

Our Subcontract Order Workflow gives information about our ordering process for Approved Suppliers.
