save on gas, save on electricity

Becoming a customer

Even if you are based outside the natural gas supply area, you can still become a firmus energy customer, as we also have a licence to supply electricity.

If you have a half hourly meter and your business is based in Northern Ireland, firmus energy may be able to give you a quote for your electricity needs.

Call us on 08456 08 00 88 or email us on furtherinfo@firmusenergy.co.uk to find out more.

Current Customers

As a current customer, your account manager will be in regular contact to ensure that we are meeting your needs.
