First Utility is the largest of the ‘second tier’ energy suppliers in the UK. The company supplies gas and electricity to 2% of the households and businesses in the UK and last year alone added close to 300,000 new customers. What separates First Utility from the Big Six (besides market share) is the fact that they don’t generate any of the electricity they supply. Instead they source most of it from Shell which in turn purchases it from the global market.

Around 70% of the UK is on a standard tariff with their energy supplier, this is the automatic default tariff if you don’t choose to switch to a fixed one. The standard tariffs are often overpriced and this usually goes unnoticed to most people who are currently on them. These extortionate energy rates accumulate to a whopping 3.4 billion pounds a year in the UK and First Utility believe more needs to be done to inform customers about cheaper alternatives.

First Utility are passionate about saving customers money and claim to be able to save you £235 per year on your energy bills. If you would like to discuss any of the First Utility energy tariffs the contact number for First Utility you can call 0843 509 2515 which will get your directly through to the First Utility Customer Service team.

About First Utility

First Utility can trace its origins to 2008 when it was spun off from First Telecom. Being a new player on the scene they weren’t faced with the costs associated with migrating hundreds of thousands of customers from legacy technology like many of the Big Six eventually would. As such they hit the ground running and by September 2015 they were already expanding into Germany.

The executive team is currently made up by 9 individuals, CEO Ian McCaig joined First Utility back in 2011 with a passion for providing significantly cheaper energy bills for households across the UK. The overall business ethos of First Utility is to have customers spending more on what they need rather than what they want. With this in mind Managing Director Ed Kamm’s business aim is to empower and encourage customers using the latest energy saving technologies ultimately saving them as much money as possible.
