Welcome to Spirit Energy

We are award winning designers and installers of systems for renewable energy generation, energy storage and energy management. We specialise in on-grid and off-grid solar and battery storage, and in LED lighting and lighting controls. We also specify and install EV chargers (off-street). We provide integrated solutions, combining technologies so that they work together with optimum efficiency.

Our vision for the future is for every building to have on-site power generation and storage, creating a grid of interconnected ‘micro’ power plants. Our mission is to make that future happen faster.

Our clients include homeowners, corporates, councils, consultants, M&E contractors, housebuilders and architects, as well as facilities managers, schools, colleges and universities. We are committed to technical excellence and fanatical about customer service. Every project is managed in-house using our own project managers and installers.

We are MCS certified installers for solar PV, and OZEV accredited for electric vehicle charging. We are NICEIC approved, Tesla certified, SunPower approved and CHAS health and safety accredited.
