The Opportunity

At Holcim UK, we’re building progress for people and the planet, and we’re looking for an experienced Senior HGV Mechanic to join our team at our Thames Materials site. This is a hands‑on role where you’ll play a key part in maintaining and improving the reliability of our vehicle fleet, supporting the growth and development of other HGV Mechanics on site. We’re looking for a skilled HGV Mechanic to work on a mixed fleet of tipper and grab trucks, carrying out everything from routine servicing through to diagnostics and MOT preparation work, ensuring all vehicles are safe, compliant and ready for operation. You’ll be responsible for keeping our fleet operating efficiently, minimising downtime and ensuring all maintenance is completed to a high standard. As a senior member of the team, you’ll also support best practice across the workshop and contribute to continuous improvement.

What You’ll Bring

• Proven experience as an HGV Mechanic / HGV Technician, ideally in a similar fleet environment
