The UK’s Premier Plug-in Solar & Energy Storage Supplier

At Certus Energy Limited, our name defines our promise.
Derived from Latin, Certus means sure, certain, reliable — and that is exactly what we deliver through every battery system, power solution, and partnership we provide.

We are not generalists. With over 40 years of experience in inverter and critical power supply systems, our foundations are built on engineering discipline, not sales trends. From industrial automation and telecoms to mission-critical infrastructure, we understand what reliable power truly means — and how to deliver it consistently.

That expertise now drives our focus on energy storage and solar integration, where reliability is not optional. Our systems are designed to perform, endure, and support long-term energy independence for homes, businesses, and off-grid applications across the UK.

Built on Engineering. Driven by Independence.

We are proud to partner with MW Energies, a European-focused energy solutions provider aligned with the transition toward decentralised, self-sufficient energy systems.

Their strategy reflects a wider shift in the energy market — away from reliance on centralised generation and toward localised production, storage, and control of energy. Across Europe, this transition is accelerating as countries invest heavily in renewables, storage, and grid flexibility to reduce dependency on traditional energy sources and improve resilience.

Together, Certus Energy and MW Energies bring this vision to the UK market:

  • Enabling self-consumption and energy independence
  • Supporting the integration of battery energy storage with solar
  • Delivering systems designed for real-world performance, not theoretical output

This partnership combines proven engineering heritage with forward-thinking energy strategy — ensuring our customers are not just adopting renewable energy, but truly gaining control over it.

Certainty in Every System

At Certus Energy, we believe energy should be dependable, understandable, and in your control.

That’s what Certus stands for.
And that’s what we deliver.
