Why Leep is the smart choice versus DNO’s

Our dedicated Extra High Voltage (EHV) team strengthens our position as one of the UK’s leading Independent Distribution Network Operators (IDNOs).

We understand the complex requirements of data centres and other power-dense users, and we apply deep technical expertise to deliver grid connections, 132kV and 33kV networks, and smart energy storage solutions. By combining engineering capability with flexible commercial models, we ensure reliable, cost-efficient and future-ready power systems tailored to your operational platform.

Cost effective – Time efficient

We can adopt multiple standards and lowercost solutions that DNOs won’t. That flexibility unlocks capex savings, supply-chain efficiencies and faster delivery. If there’s a more cost-effective or time-efficient route, we’ll find it and pass the benefit on. On top of that, our ongoing charges are typically lower than a DNO’s.

Great to work with

You’ll get through directly to the people you need to speak to. No having to navigate a call centre and wait for a call back. We are nimble, agile, experienced and empowered. That’s how we crunch delivery schedules, keeping your project on track.

All the expertise you’ll need

Whether its unlocking supply chain blockages, using innovation to get your project kickstarted or working smartly to overcome challenges, you’ll be pleased to have a responsive, clientcentric and delivery focussed partner, working with you to deliver rapid connections.

Commercial flexibility

Capital contributions as standard. We can structure to minimise ongoing charges or maximise AV payments to help offset your project capex.

Our EHV solutions

We deliver unmatched value by blending innovation, transparency, and a customer-centric approach. With our proven expertise in network adoption, we ensure seamless delivery tailored to your needs.

132kV, 33kV Networks & Grid Connections

We deliver tailored grid connections that meet the exact power and resilience requirements of your site, ensuring capability for today and scalability for tomorrow.

Smart Battery Energy Storage, Renewable Energy Connections

Our storage solutions enhance site resilience, optimise energy performance and support decarbonisation strategies.

Power to Data Centres

Securing power for large-scale digital infrastructure can be challenging. Costs, delays and lack of visibility from traditional routes often impact viability.

Repurposing Waste Heat

We help data centre operators unlock additional value by repurposing waste heat into local heat networks, reducing grid demand and boosting sustainability.

Our EHV Solutions

Powering flexible, low-carbon infrastructure

BESS & Renewable Energy Connections is essential to grid stability and renewable growth. We unlock its full value by providing tailored grid connections, transparent adoption pathways and end-to-end delivery support.

With proven IDNO expertise, we ensure projects move from feasibility to energisation with certainty.

End-to-end grid connection and network adoption

As solar generation grows, dependable grid access is vital. Leep provides integrated design, adoption and operation services that accelerate energisation and maximise long-term asst performance.

As an IDNO, we deliver commercially flexible, future-ready solutions for developers, landowners and consultants across the UK.

Adoption-led delivery and smarter grid connections

Our adoption-first model aligns design, build and operation from day one, reducing rework, improving visibility and ensuring a smooth pathway to energisation.

We consult and advise on connection and adoption strategies, anchored by your commercial and technical needs. The result being clarity, reduced risk and efficient delivery through every stage of your project.

Flexible strategies for large-scale digital infrastructure projects

Securing power for large-scale digital infrastructure can be challenging. Costs, delays and lack of visibility from traditional routes often impact viability.

Solutions first

Our early-engagement approach removes barriers. We avoid advance reservation charges, provide transparent data, and create flexible network strategies tailored to your site’s footprint, programme and resilience needs.

We bring clarity to a traditionally opaque process, ensuring informed decisions early and reliable delivery throughout.

The Future of Data Centres & EHV Services

As data centres are projected to contribute an additional £44 billion to the UK economy by 2035, Leep Utilities is committed to being a trusted partner in this expansion. Our ongoing investment in professional development, cutting-edge solutions, and expert personnel ensures that we are ready to support the growing needs of the data centre industry and high-consumption customers across the UK.
