HIU Service Engineer

The HIU Service Engineer is responsible for carrying out planned preventative maintenance (PPM) on Heat Interface Units (HIUs) and Mechanical Ventilation with Heat Recovery (MVHR) systems across residential developments throughout London. The role is focused solely on servicing activities, ensuring equipment is maintained in accordance with manufacturer recommendations, contract requirements, and company procedures. The engineer is typically scheduled to complete between 8-10 HIU or MVHR services per day, working independently to a planned programme of maintenance visits. Duties include conducting routine inspections, servicing components, identifying defects, recording asset information, producing accurate service records, and highlighting any remedial works required.

• Reactive maintenance or emergency call-outs.
• Breakdown attendance.
• Fault diagnosis beyond service observations.

• Major repairs, commissioning, or project work.
The position is therefore highly structured, with the engineer's primary objective being to complete scheduled services safely, efficiently, and to a high standard while maintaining excellent customer service within occupied residential properties. Success in the role is measured through service completion rates, quality of service records, compliance with maintenance procedures, customer experience, and the identification of potential issues before they develop into failures.

• Providing reactive maintenance for loss of services within required Service Level Agreements
• Identification and review of equipment faults carrying out repairs where required
