This coming weekend (Nov 14 – 16) is the Great British Switch when comparethemarket.com is encouraging those aged 65 and over to see how much money they could save on their energy bills this winter by switching to a new supplier. Research suggests that around 90% of those aged 65 and over have never tried to switch energy supplier, despite the fact that a typical household can save up to £350 a year by switching energy suppliers. My husband switches regularly as the best deal one year doesn’t mean you’ll be on the best deal next year when the deals change.
