Contact us

We’re proud of the customer service we offer, but please remember; we’re not a 24/7 call centre kind of business. That means you don’t have to negotiate frustrating touch tone answering systems, and you’ll rarely have to wait in a queue whilst we remind you via recorded message that your call is important to us. Instead, we’ll show you how important your call is to us by answering the phone as quickly as possible and handling your enquiry with an engaging combination of expertise and understanding.

That’s because when you deal with Zenergi you’ll always speak directly to a friendly and knowledgeable expert who will be happy to assist you with your enquiry. As well as handling your initial query, we may even be able to offer additional services and advice that could help you over and above your expectations.

Our energy expertise isn’t restricted to customer service. We are also able to offer more technical services, so no matter the nature or complexity of your enquiry, why not get in touch to find out exactly how you could benefit? After all; we’re here to help.

By submitting this form, you consent to your data being collected and stored, and consent to us contacting you by email or telephone with regards to your enquiry.
