Our story

Custom Renewables was founded with the aim to provide our customers with two critical and non-negotiable standards. One; the most efficient heating system design possible that delivers the result of a cost-effective system and maximum energy efficiency. And two; the very best customer service available from initial contact, through to project completion and ongoing technical support.

We understand that most of the industry provides the opposite, unreliable systems, low efficiency, unclear communication, technical jargon, and below average support. We believe that you deserve better, and that’s where we step in as an award-winning contractor.

As a consumer, we know that you want your heating, energy and hot water needs to be made as simple as possible. We also know that having a highly efficient system that reduces your energy bills and has a significantly lower impact on the environment ticks all the boxes.

Our mission

Custom Renewables is on a growth path to deliver the most efficient and affordable energy solutions whilst being the most customer focused company in the market and supporting the government’s goal of being a net zero country by the year 2050.

Our core company values:

Efficiency. “Clever design suited to the exact build up of your property and your exact requirements.”

Quality. “We take great pride in every install we complete, and our aim is to make every part of our customers journey seamless and enjoyable.”

Support. “We make things simple and care for our customers all of the way through the design stage to ongoing servicing.”

Improvement. “We are always on the cutting edge of new systems, technology and what works best to better serve our customers.”
