Hello and welcome to Energy Company Numbers, the energy company contact number directory. We make it super-easy to contact energy suppliers on the phone.

Energy Company Numbers

At Energy Company Numbers, we connect energy customers with their energy service provider. We achieve this through affordable 0843 telephone numbers and by publishing Freephone 0800 numbers. Most energy suppliers hide their customer service telephone number because they want their customers to create an online support ticket. We break down this barrier.
