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
