The Opportunity
A leading London-based facilities management provider, renowned for delivering first-class service across luxury, high-rise residential developments, is looking to appoint a Mechanical Engineer to join its established foot-mobile team across Central London. This is an excellent opportunity to work across a prestigious portfolio of multi-block estates, including residential towers, communal podiums and complex plant infrastructure. The role is heavily focused on compliance-led maintenance, structured PPM delivery in line with SFG20 standards, and ensuring the ongoing performance and reliability of critical building services. You’ll play a key role in maintaining and optimising mechanical systems, with a strong emphasis on fault finding, troubleshooting and asset performance, rather than purely installation work.


Key Responsibilities

• Deliver planned and reactive mechanical maintenance across landlord and communal systems
• Carry out PPM tasks in line with SFG20 schedules and asset registers
• Diagnose faults across heating, cooling and domestic water systems, ensuring minimal disruption
• Undertake pipework installation, modifications and repairs (LTHW, CHW and domestic systems)
• Maintain key plant equipment including air dirt separators, strainers and valves
• Perform vessel servicing, including draining, flushing and recommissioning
• Carry out plate heat exchanger maintenance and flushing
• Respond to plant failures and restore system functionality efficiently
• Support compliance-driven remedial works identified through maintenance activities
• Accurately record all works via CAFM/mobile systems, ensuring full compliance and audit trails
• Liaise professionally with site teams, contractors and residents
• Adhere to all health & safety procedures, including permit-to-work and RAMS
• Participate in a 1 in 4 on-call rota (post-probation)

What We’re Looking For

• Qualified Mechanical Engineer (City & Guilds, NVQ or apprenticeship)
• Strong background in compliance-led maintenance within commercial or residential environments
• Solid understanding of building services systems (heating, cooling and domestic water)
• Proven experience with pipework systems and mechanical plant
• Experience working within structured PPM environments (SFG20 desirable)
• Strong fault-finding and diagnostic capability
• Good understanding of statutory compliance (pressure systems, water hygiene, etc.)
• Ability to read and interpret mechanical drawings and schematics
• Comfortable working in a foot-mobile role across Central London
• Confident using digital reporting/CAFM systems

Why Apply?

• Work across a high-end Central London portfolio
• Join a well-established and respected FM provider
• Exposure to complex, modern building services systems
• Stable, permanent role with clear structure and support
• Opportunity to develop within a professional, compliance-driven environment
