In this technically focused role you will support the efficient operation of M25 tunnels by delivering planned and reactive maintenance across electrical, electronic, mechanical and building systems. Working under the direction of the Tunnel Maintenance Manager and Supervisors, you will contribute to the upkeep of critical assets, ensuring they operate effectively under normal and emergency conditions.

This is an excellent opportunity for a skilled and safety‑conscious technician who enjoys working in a challenging operational environment and making a direct contribution to network resilience.

Location and working arrangements: The role is based from CPS Hatfield and South Mimms depots, with regular work across the M25 tunnel network and occasional travel to other locations where required. Flexibility is essential: you will be required to attend incidents, support planned maintenance and participate in the standby and call‑out rota for Holmesdale, Bell Common and Hatfield tunnels.

You will complete all required records, including daily worksheets and maintenance reports, ensuring accurate and timely documentation.

The role requires you to read technical drawings, carry out fault finding and complete repairs independently where appropriate. You will deliver civil, electrical and mechanical maintenance activities within your competency, including out-of‑trade tasks when required, under the direction of senior supervisors. You will operate vehicles for maintenance purposes, ensure that all health and safety requirements are met, and adopt safe systems of work at all times. You will maintain vehicles, plant and equipment in a safe and serviceable condition and complete routine checks and drivers’ records in line with company procedures. You will attend incidents and work in accordance with operational policies to support the safe and timely clearance of hazards. You will actively promote Connect Plus Services values, maintain a relentless focus on Zero Harm, support sustainability initiatives and comply with the Balfour Beatty Electrical Safe System of Work. You will also work in close collaboration with internal teams and external partners, including National Highways and specialist subcontractors, to ensure consistent and high‑quality service delivery.
