Dorset's Integrated Renewable Energy Specialists

Our Story

Built on Experience. Driven by Integration.

Renerji was established in 2025 by a team with over 40 years of combined experience in the renewable energy and building services industry. We had seen too many homeowners end up with systems that didn't work together — a heat pump here, solar panels there, a battery installed as an afterthought. We knew there was a better way.

Our approach is different. We design every system as a whole, ensuring your heat pump, solar panels, battery storage, and EV charger all work in harmony — reducing your energy costs as much as possible and giving you a home that runs on clean energy around the clock.

From our base in Dorset, we serve homeowners across Dorset, Hampshire, and Wiltshire. Every member of our team is fully qualified and our installations are backed by MCS certification, TrustMark registration, and NAPIT certification — the accreditations that matter most for quality, compliance, and grant eligibility.

Whole-System Thinking

We design your energy system as a whole from day one. Heat pump, solar, battery, and EV charger all working in harmony — not bolted together as an afterthought.

Uncompromised Quality

Every Renerji installation uses premium products and meticulous workmanship, carried out by fully qualified, certified engineers. Our accreditations are your assurance.

Local Expertise

Based in Dorset, we know the region and are invested in the communities we serve. Responsive, local, and genuinely committed to your home's energy future.
