The Design department is responsible for developing innovative, practical, and fully coordinated mechanical and electrical building services solutions tailored to each project. Working closely with clients, project teams, and the BIM department, the design team transforms concepts into detailed, build-ready technical designs that meet regulatory standards, client specifications, and sustainability goals. Their work underpins the technical accuracy and efficiency of our installations, ensuring seamless integration from planning through to construction.

As an Electrical Design Engineer, you will help deliver the low-carbon energy infrastructure that supports Alternative Heat’s commitment to decarbonisation. You will develop coordinated electrical designs for projects across healthcare, education, leisure and residential sectors, including LV distribution, load assessments, circuit design, plant power supplies, general and emergency lighting, metering, generators, transformers, and electrical interfaces with mechanical plant and BMS packages. Working with the electrical, mechanical and BIM teams, you will produce calculations, schematics, schedules, and coordinated layouts from design development through construction and handover. Your work will contribute to safe, buildable, and energy-efficient systems that reduce carbon emissions and support our clients’ decarbonisation objectives.
