First Utility is a supplier of electricity and gas in the UK. Although only having a market share of less than 1%, the company is classed as the seventh largest UK supplier (as of October 2013).


The company was formed in 2008 as a spin-off from First Telecom. They signed a three year sponsorship deal in January 2014 for the rugby Super League.

First Utility positioned itself to offer energy customers a more transparent and value for money service than the ‘big six’ energy suppliers. Their innovative approach is illustrated by the use of smart meters to check energy usage daily (gas) and every 30 minutes (electricity). This is designed to provide more accurate bills and remove the need for customers to read their meters, and helps them analyse when they are using the most energy. Simplified charging is aimed to help customers know exactly where they are.

The company also pledge to offer competitive pricing and responsive customer service through detail touches like answering incoming calls promptly and dealing with customer correspondence swiftly and thoroughly.

Making a complaint

Call the First Utility complaints line on 0844 409 8599 between 8.00am - 8.00pm Monday to Friday and 9.00am - 1.00pm Saturdays to seek a resolution.

If your complaint cannot be successfully resolved, then their Customer Case Resolution team will try and resolve it. If this is still unsuccessful, then you can take the matter up with the Energy Ombudsman (details below).
