• Have strong knowledge of heating systems, boilers, and associated plant.
• Comfortable using tablets or computers for job logging and documentation.

This is a hands-on and varied role within a supportive FM team, providing stability, regular hours, and the chance to make a real difference maintaining essential public service buildings.
