Role purpose
We are creating a single, central Buyer role to take ownership of purchasing across all of our projects.

will source and procure the materials, plant, equipment and subcontracted services our sites need – on
time, at the right price and to the right standard. This is a hands-on, get-it-done role for someone who
enjoys owning the full buying cycle and being the go-to point for procurement across the business.

- Raise, issue and track purchase orders, assist those processing GRN and invoices, resolving discrepancies with suppliers and accounts. Amend Purchase Orders if required.
- For plant and equipment, the Plant Manager sources the requirement and the Buyer enters it into the system to raise the relevant purchase order, managing off-hire promptly to control cost.
- Interface with the plant department for consumables and bulk aggregate haulage.
- Raise the relevant purchase orders for subcontracts produced by the Commercial team.
- Procure muck away and recycling services.
- Build and maintain strong relationships with the existing supply chain and identify new, reliable suppliers where needed.
