• Diagnosing faults, identifying remedial works and ensuring equipment operates safely and efficiently.
• Responding to client queries professionally and providing clear updates on completed works.
• Completing service reports, inspection records and maintenance documentation accurately.
• Travelling between sites within the contract area and managing your workload independently.

• Good communication skills and a professional, customer-focused approach.
• The ability to prioritise workloads, work independently and respond effectively to reactive maintenance issues.
• Flexibility to participate in an on-call rota.

Security Clearance: Due to the nature of the contract, the successful candidate must be willing and eligible to undergo the required police security clearance process. This process can take approximately 7-10 months, so applicants should be prepared for an extended clearance period.

What’s on Offer?

• The opportunity to work on a high-profile public sector facilities maintenance contract.
• A mobile role covering two closely located sites within one dedicated contract.
• Ongoing training and professional development.
• The opportunity to further develop your experience within a structured facilities management environment.
