With higher energy bills looming and warnings of worse to come in the new year, many households could save up to £173 a year by switching to a fixed deal.

Millions of households in Great Britain will face the highest energy charges in three years after it was announced that the government’s price cap will rise again in October. This will be the second increase in three months.
