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 engineer is typically scheduled to complete between 8-10 HIU or MVHR services per day, working independently to a planned programme of maintenance visits.

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.

Key responsibilities

• Completing scheduled servicing of Heat Interface Units in accordance with the servicing procedure
• Providing reactive maintenance for loss of services within required Service Level Agreements
• Identification and review of equipment faults carrying out repairs where required
• Inputting and maintaining documentation and records using the company asset management software
• Carrying out general ad hoc maintenance tasks within Energy Centre Plantrooms
• Working in a safe manner and in accordance with the company's Health & Safety policy
