It was also claimed that the link between gas and oil prices mean the cost of energy is set to increase.

"I think it's a reality not only in the UK but in western Europe and North America - energy is going to become relatively much more expensive in the future."
Earlier this month, reports in the Times claimed that British Gas is considering the introduction of a new set of price rises in the next few months.
