SSE has become the last energy firm from the Big Six to hike bills, prompting a minister to call on consumers to "vote with their feet".

SSE has blamed wholesale price increases and Government policy for the increase in its tariffs.

The group is increasing electricity and gas bills by an average of 6.7%, or £76 per year, in a move affecting 2.36 million customers.

Claire Perry, energy and clean growth minister, said: "It is extremely disappointing that SSE has decided to announce this unjustified price rise - the highest yet from the Big Six - ahead of the new law coming into effect later this year.

"Consumers should vote with their feet. Switching suppliers will always help consumers get the best deal."

The price changes will come into force on July 11, with a 5.7% rise for gas and 7.7% for electricity bills.
