HIU / Mechanical Engineer - District Heating

Location: King's Cross, London (Static Site)Salary: £52,000 + Unlimited Overtime (OTE £70,000+) + Package

The Opportunity

My client is a leading specialist in district heating and high-spec mechanical environments, and they are looking to recruit an experienced HIU / Mechanical Engineer for a flagship static site in King's Cross.

This is a rare opportunity to work in a high-tech, modern energy centre, supporting one of London's most advanced district heating networks. You'll be part of a true engineering environment-not just maintenance, but working with cutting-edge systems where quality, precision, and expertise are genuinely valued.

Essential Requirements

• Strong experience working on HIUs (Heat Interface Units)
• Specific experience with Evinox HIU systems (highly desirable)
• Proven background in mechanical maintenance within commercial environments
• Experience working in plant rooms and on mechanical building services equipment
• Strong fault-finding and diagnostic skills
• Understanding of district heating systems (highly advantageous)

Desirable

• Experience within district heating or energy centres
• Relevant mechanical or building services qualifications
• Knowledge of BMS interaction with mechanical systems

Package

• £52,000 basic salary
• Unlimited overtime (OTE £70,000+)
• Static site in King's Cross
• Training and development opportunities
• Long-term career progression within a specialist and growing sector

The Role

Working on a static site, you will be responsible for the maintenance, fault-finding, and repair of Heat Interface Units (HIUs) and associated plant within a district heating network.

This role offers a great balance of stability, technical challenge, and earning potential through unlimited overtime.

Key Responsibilities

• Maintenance, fault diagnosis, and repair of HIUs across the site
• Strong focus on Evinox systems
• Working on district heating infrastructure and associated plant
• Mechanical maintenance within plant rooms, including pumps, valves, heat exchangers, and pipework
• Ensuring all systems operate efficiently and in line with compliance standards
• Supporting system optimisation and continuous improvement

What Makes This Role Stand Out

• Static role - no travel, based in a flagship King's Cross site
• Work within a high-tech district heating network using leading technologies
• Join a business that offers a proper engineering environment-not just reactive maintenance
• Unlimited overtime available - realistic earnings up to £70,000+
• Excellent career progression opportunities within a growing, specialist sector

Career Prospects

My client is committed to developing engineers within the district heating sector, offering progression into:

• Senior Engineer roles
• Specialist HIU / District Heating expert positions
• Supervisory or technical leadership roles

If you're an engineer who takes pride in your work and wants to be part of a modern, forward-thinking engineering environment, this is an outstanding opportunity.
