The Role of HV and LV Ducting within the UK Power Network
As the UK steps up investment in the National Grid, electric mobility and new housing, there is growing demand for future-ready electrical networks. Hidden beneath the surface of the UK sits either high voltage (HV) or low voltage (LV) ducting servicing the countries electrical distribution.
These underground systems protect and organise electrical cables, ensuring long-term safety and serviceability across a wide range of applications. From housing plots and commercial developments to transport infrastructure and EV networks, ducting is part of the groundwork that keeps everything powered.
What is HV and LV Ducting Used For?
HV and LV ducting provides a protective route for electrical cables. It shields power lines from physical damage, water ingress and environmental exposure. Contractors will already know the basics, but getting the right spec in early is what protects ROI and prevents costly remedial work. It’s also important to understand that Distribution Network Operators (DNO’s) specify their own particular grade of duct.
In the UK, ducting systems used in electrical distribution need to meet specific standards. One of the most recognised is ENATS 12-24, which sets out requirements for the materials and performance of ducting for electricity distribution. This standard is widely referenced by Distribution Network Operators (DNOs) and utility providers.
More than just a requirement, the right ducting solution procured at the right place can also:
- Reduce installation costs and time on site
- Improve long-term safety for workers and the public
- Enable easier access for future upgrades or repairs
- Offer greater availability by sourcing from a wider range of suppliers and manufacturers
Power Infrastructure for New Housing Developments
LV ducting plays a major role in new-build developments, from routing electricity to homes and street lighting through to supporting future upgrades such as smart metering and connections to the operator’s network. Installing compliant ducting during early groundwork makes a big difference and avoids disruptive retrofitting at later stages.
As housing schemes grow more complex and more connected, electrical infrastructure needs to be both compliant and scalable. Developers are increasingly planning ducting routes early, not just for power supply but also for smart infrastructure.
Ducting and Road Infrastructure
Modern road networks depend on reliable electrical systems for lighting, traffic signals, emergency systems and signage. HV and LV ducting enables safe, organised connection of these systems across large-scale transport infrastructure.
In motorway upgrades and Smart Motorway schemes, ducting is often subject to heavy loading, vibration and extreme weather. That’s why product selection must be based on real-world performance and long term durability.
Pre-installed ducting also allows highways teams to add intelligent traffic systems, roadside EV chargers and other upgrades without ground disruption. This kind of future proofing saves time and budget over the lifespan of the asset.
Enabling EV Charger Infrastructure
With the government’s Zero Emission Vehicle (ZEV) mandate now live, the roll-out of electric vehicle (EV) charging points is picking up speed. As of June 2025, there were 82,369 EV charging points across the UK*, with thousands more planned over the coming months.
EV charging infrastructure is only going to grow, and site planners need to think long-term. At Plastech® we’re already supporting clients in the early stages of design and groundwork, making sure their electrical infrastructure can meet current demand and future growth.
Sourcing LV & HV Ducting
HV and LV ducting isn’t often seen, but its impact is felt across the full spectrum of infrastructure delivery. From housing and highways to EV rollouts and regeneration schemes, it plays an important role in building smarter, more connected systems.
As demand grows, so does the need for compliant, durable and easy-to-install ducting solutions. At Plastech® we work closely with contractors, developers and procurement teams to make sure electrical infrastructure is set up to last and sourced at the best price.
