Your Role

As a Consulting Engineer in the District Heating Design team, you’ll play a pivotal role in delivering technically sound, timely, and cost-effective design solutions. Working across a variety of innovative projects, your work will directly support low-carbon heating in both new developments and existing buildings.

• Produce detailed technical specifications and documentation (e.g., controls philosophy, CDM risk assessments, water quality specs).
• Engage with clients, developers, and project teams through regular meetings to manage design progression and risks.
• Support delivery quality by collaborating with the QA team and overseeing contractor compliance during commissioning and handover.
• Mentor Graduate Engineers and contribute to their technical development.
• Participate in an accelerated training programme to support your growth within the sector.

What We're Looking For

• 2+ years’ experience in building services consulting, ideally with exposure to communal or district heating systems.
• Strong understanding of heat network lifecycle - design, construction, commissioning, and operational challenges.
• Skilled in technical design delivery across heating and hot water systems.
• Proficient in Microsoft Office Suite.
• Experience with AutoCAD, QGIS, EnergyPro.
• Hands-on design experience with energy centres, networks, and building connections.
