Senior Electrical Design Engineer (Decarb Retrofit - Built Env.)

Overview of role 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. Role responsibilities and requirements • 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. Key skills and qualities needed 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. Further information 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.
