• Carry out pipework repairs and alterations, diagnose leaks, pressure/circulation problems and air ingress, and drain, vent, fill and recommission systems following maintenance.
• Use mechanical drawings, plant information and BMS data to investigate heating, cooling and ventilation performance issues.
• Support specialist contractors while retaining ownership of the engineering issue and complete quoted, minor and ad‑hoc building‑services works as required.
• Accurately record maintenance, defects, remedial actions and plant condition in the CAFM system and produce basic technical/condition reports where required.
• Comply with HSE procedures, permits, RAMS and safe isolation requirements; maintain high standards in plant rooms and workshops and act professionally with the client, tenants, contractors and public.

• NVQ Level 3, City & Guilds Level 3 or equivalent recognised qualification in Mechanical Engineering, Building Services Engineering, Plumbing & Heating, HVAC or a closely related discipline.
• Proven hands‑on mechanical maintenance and fault‑finding experience within commercial, industrial or large‑scale buildings.
• Demonstrable experience dismantling and rebuilding pumps/rotating equipment and replacing bearings, seals, gaskets, belts and couplings.
• Experience maintaining pumps, motors, valves, LTHW/CHW systems, AHUs, FCUs, domestic water systems and associated HVAC plant.
• Practical pipework repair/alteration experience and ability to safely isolate, recommission and return mechanical plant to service.
• Ability to read mechanical drawings, schematics and plant information and make sound engineering decisions within level of competence.
• Good understanding of PPM regimes, mechanical Health & Safety requirements and Permit to Work/safe systems of work.
• ACOP L8 / Legionella awareness or equivalent water‑hygiene training.
• Good communication skills and ability to work independently in a client‑facing, occupied and public‑facing environment, including occasional out‑of‑hours work where required.

Desirable Skills & Experience

• Experience within shopping centres, heritage buildings, hospitals, universities, hotels or other complex estates.
• Experience with booster sets, pressurisation units, plate heat exchangers, calorifiers, control valves and closed‑loop heating/chilled‑water systems.
• Mechanical plant overhaul/refurbishment, water treatment and closed‑system water quality experience.
• BMS operation/fault investigation, VSD‑controlled pumps and fans, and basic motor fault diagnosis.
• Building fabric repairs, minor electrical works where appropriately trained and competent, and formal Permit to Work systems.
