Who We Are

GivEnergy Specialists — and Beyond

The Energy Collective is an independent renewable energy consultancy specialising in technical support, fault diagnostics and system optimisation for homeowners, businesses and installers across the UK.

Our team worked as GivEnergy product specialists — the people the support desk called when they needed answers. Right now, GivEnergy inverter and battery support is our primary focus, where demand is highest. We're also well versed in EV chargers, water diverters and heat pumps, and plan to expand further as the GivEnergy backlog eases.
