Bringing together civil, structural, electrical, and environmental engineering to deliver comprehensive substation design services across the UK.
Matrix Consulting Engineers provides end-to-end substation design services for projects ranging from 11kV distribution substations through to 132kV grid substations. Our multi-disciplinary team brings together civil, structural, electrical, and geotechnical expertise under one roof — reducing interface risk and delivering fully coordinated design packages.
We work directly with Distribution Network Operators (DNOs), Independent Distribution Network Operators (IDNOs), EPC contractors, and private developers. Whether the project is a new-build primary substation, a grid connection for a renewable energy scheme, or a compact indoor substation within a commercial development, our approach is the same: technically rigorous, buildable, and delivered on programme.
Our approach is methodical and coordinated across all disciplines. We begin with a thorough feasibility study to understand grid connection requirements, site constraints, and programme drivers, feeding into conceptual design where we establish the optimum layout, voltage levels, and equipment specification.
Detailed engineering follows with full production of civil, structural, and electrical drawings, specifications, and calculations. We manage the interface with DNOs and statutory bodies to support regulatory approvals and keep the programme on track. Throughout procurement and construction, our team provides technical support including design queries, site inspections, and construction-stage BIM coordination.
We eliminate coordination gaps between separate companies, giving you a single point of responsibility for the entire substation design package.

Data centres, the backbone of our digital infrastructure, require a reliable and uninterrupted power supply to ensure the continuous operation of servers, storage systems, and networking equipment. To achieve this, data centres are typically powered by electrical substations, which play a crucial role in transforming and distributing electricity to meet the specific needs of these facilities. Here’s a detailed explanation of how this process works:
For data centres, a dedicated substation, often located on-site or nearby, steps down the voltage from the secondary substation to the specific levels required by the data centre’s infrastructure. This is achieved using additional transformers.
Once the electricity reaches the data centre substation at the appropriate voltage, it is distributed within the facility through a complex network of switchgear, circuit breakers, and distribution panels. This internal distribution network ensures that power is delivered to all critical components, such as servers, cooling systems, networking equipment, and lighting.
The first step in distributing electricity to data centres involves primary substations. These facilities step down the high-voltage electricity from the transmission lines to a lower voltage (commonly between 33 kV and 132 kV) using large transformers. The primary substation acts as a bridge between the transmission network and the distribution network.
Electrical substations are a crucial component of the UK’s electrical grid, facilitating the transformation and distribution of electricity from power generation sites to end users. They are strategically located across the country to ensure the efficient and reliable delivery of power. Here’s a detailed overview of where electrical substations are primarily used in the UK:London, Manchester, Birmingham, Glasgow, and Other Major Cities:
Merseyside, West Midlands, South Wales, Teesside:
Scottish Highlands, Wales, South West England, East Anglia:
East Coast, South Coast, North Sea Oil Rigs:
Drax Power Station (Yorkshire), Hinkley Point (Somerset), Sizewell (Suffolk):

The UK's transition to net zero is driving rapid growth in grid-scale battery energy storage. We provide civil and structural design for BESS substation compounds — transformer and switchgear foundations, battery container plinths, cable trench networks, access roads for abnormal loads, and surface water drainage with oil containment. BESS sites present specific challenges including thermal management spacing, NFCC fire separation distances, and phased construction sequencing.
Solar farms, onshore wind, and hybrid schemes all require substation infrastructure to export power to the grid. We deliver foundations, drainage, earthworks, access roads, and structural designs for switchrooms and gantry steelwork. Where sites are subject to flood risk, we design critical platforms above predicted flood levels and incorporate EA and LLFA flood resilience measures.
Common questions about our substation design services. If you need more detail, get in touch and we’ll be happy to discuss your project.
Substation design is a multi-disciplinary activity involving civil engineering (drainage, earthworks, access roads), structural engineering (foundations, bunds, buildings, steelwork), electrical engineering (primary and secondary systems), and geotechnical engineering (ground investigation and foundation recommendations). At Matrix, we bring these disciplines together under one roof to deliver fully coordinated design packages.
We provide civil and structural design services for substations from 11kV distribution substations through to 132kV grid substations. This covers secondary substations, primary substations, grid substations, and specialist substations for BESS, data centres, and renewable energy connections.
Yes. We work with Distribution Network Operators and Independent Distribution Network Operators across the UK, as well as EPC contractors and private developers delivering substation projects for grid connections.
Yes. We design substation infrastructure for battery energy storage systems, solar farms, and wind farm connections. This includes transformer compounds, battery container plinths, cable networks, and grid connection infrastructure.
We provide the full civil and structural design for data centre substation infrastructure, including transformer foundations and oil containment bunds, HV and LV switchroom structures, cable basement and riser designs, standby generator compounds, segregated cable trench networks, access roads for abnormal loads, and surface water drainage. We design for N+1 and 2N redundancy configurations and use BIM-coordinated workflows to manage the tight spatial coordination these projects demand.
