MORE than a quarter of households do not know if they are on the most expensive standard variable tariffs (SVTs) for gas and electricity and one in 20 do not know who supplies their energy.

A Bulb energy poll found six per cent of people do not know who their supplier is, while 28 per cent either do not know or are not sure if they are on a poor value SVT.

This figure rises to 53 per cent of 18 to 24-year-olds, while 16 per cent of 55 to 74-year-olds are in the same position.

The poll also suggests households may be confused over whether they have switched away from SVT tariffs. Some 44 per cent said they had switched in the last year, but Bulb cited Energy UK figures showing 22 per cent of the UK’s 27.1 million households switched last year.

Bulb said it was surprised half of the “most technically savvy generation” appeared not to know what type of tariff they were on, but said this could be due to 18 to 24-year-olds typically renting accommodation and believing they were unable to switch.”
