Whether it's improving the performance of an existing building or designing a more sustainable future from the ground up, our Engineering Services team makes complex challenges feel straightforward. Combining mechanical and electrical expertise with renewable technologies, retrofit and responsive maintenance, we deliver tailored solutions that reduce energy use, lower carbon emissions and keep buildings working at their best.
About us
Driving Sustainability, Trusted to Deliver
Seddon Engineering Services is a leading mechanical, electrical and plumbing (MEP) business with decarbonisation at its heart. Our engineers, sustainability specialists and project managers design, supply, install, test, commission and maintain building services that cut carbon, reduce energy bills and keep buildings running at their best. From upgrading a school’s heating system to fitting solar panels across a housing estate, we provide practical, future-ready solutions for commercial, public sector, residential and industrial buildings. Fully accredited and appointed to leading M&E and decarbonisation frameworks, we’re a trusted partner on the journey to net zero.
Our People, our standards, your peace of mind
Our Engineers
In an industry that relies heavily on subcontracting, Seddon does things differently. Engineering Services has its own team of 60 directly eployed mechanical and electrical engineers.
They’re qualified, accredited and trained to Seddon standards, and many have grown their careers through our own apprenticeship programmes in plumbing and electrical installation. Our plumbers, heating engineers, electricians and technicians work side by side as one team. They know each other, they know our processes, and they take real pride in getting the job right first time. Because they’re our people, we can guarantee consistent quality, reliable resourcing and clear accountability from design through to handover. And as technology moves on, we keep investing in their skills, from heat pumps and solar PV to smart controls, so our clients always benefit from engineers who are ready for the future.
Working in Live Environments
Keeping buildings running while we upgrade them
Most of our M&E work happens in buildings that can’t close, such as schools, hospitals, emergency service stations, offices and people’s homes
For mechanical and electrical engineers, that means more than just keeping the noise down. It means keeping the heating on, the power flowing, the water safe and critical systems running while the systems themselves are being replaced. That’s why careful planning is second nature to our team. Before work starts, we survey existing systems, map out every isolation and shutdown, and agree a detailed phasing plan with building managers. Where services need to go off, we keep interruptions short and plan them around the people who rely on them. We schedule disruptive work out of hours, at weekends or during holidays, and we provide temporary heating, hot water or power where needed so buildings stay comfortable and operational. Throughout the project, we keep building users informed with clear notice of any planned shutdowns, so there are no surprises.
