Senior Electrical Design Engineer; Built Env Decarbonisation

This role offers an opportunity for a Senior Electrical Design Engineer to take a leading position in the delivery of decarbonisation and sustainable retrofit projects across the built environment. You will work on projects that directly contribute to the transition to low-carbon energy, shaping electrical solutions for commercial and public-sector buildings.

You’ll be trusted to provide technical leadership, coordinate complex designs, and mentor others, while working closely with clients and multidisciplinary teams to deliver safe, compliant, and future-ready electrical systems.

• Lead the design and delivery of LV electrical building services for decarbonisation and retrofit projects, including power distribution, solar PV, battery storage, LED lighting, and smart control systems.
• Take ownership of electrical design across RIBA Stages 2–5, producing calculations, single-line diagrams, schematics, schedules, and technical reports.
• Design and integrate solar PV systems, including rooftop, ground-mounted, and building-integrated solutions.
• Coordinate closely with mechanical and energy teams to support integrated low-carbon solutions such as heat pumps.
• Manage engagement with Distribution Network Operators (DNOs), from feasibility through to applications and approvals.
• Lead electrical design packages on multidisciplinary projects, ensuring quality, safety, and regulatory compliance.
• Review, QA, and sign off electrical designs in line with BS 7671, IET Wiring Regulations, and UK Building Regulations.
• Engage confidently with clients and contractors, contributing to design reviews, technical workshops, and presentations.
• Support design risk management and contribute to project delivery from concept through to completion.

• Degree in Electrical Engineering or Building Services Engineering (or equivalent).
• Chartered Engineer (CEng) status or actively working towards chartership.
• Strong background in electrical building services design within the built environment.
• Proven experience delivering low-carbon, energy efficiency, and sustainable retrofit projects.
• In-depth experience with power systems, solar PV, battery storage, lighting, and smart building technologies.
• Comfortable working across the full RIBA stages within multidisciplinary teams.
• Experience on public-sector or funding-led decarbonisation programmes (e.g. PSDS, SHDF).
• Strong communicator who enjoys leading technical discussions and mentoring junior engineers.
• Organised, commercially aware, and motivated by delivering meaningful environmental impact.

This role suits an engineer looking to take ownership of technically challenging electrical designs, develop leadership capability, and play a direct role in the decarbonisation of the built environment. Alongside a very attractive package you will expect excellent career development opportunities and a dynamic and encouraging work culture.
