First Utility in the news


February: First Utility announced a 9.7% price rise on its standard variable tariff, coming into effect on 1 April. This will add around £102 onto the average bill. First Utility blamed the rise on ‘significant increases in wholesale and industry costs over the past year’. It expects 13% of its customers to be affected.


First Utility offers a service called ‘My Energy’ that shows you where you are using energy in your home and how you can save it. It also allows its customers to compare their energy use with their neighbours, and claims that its research shows that customers’ energy consumption is reduced by around 5% in the first month after they are compared to their neighbours’.

In December 2016, Ofgem revealed that First Utility had the third highest price differential between their standard tariff and cheapest deal, though only 9% of their customers were on standard tariffs – compared with 74% of British Gas customers.
