Don’t pay over the odds for your household energy – see if you could save by switching

If your energy deal is coming to an end in May, now is the time to switch before you are automatically rolled on to an even more expensive tariff. 

Signing up for a fixed energy tariff can give you peace of mind that your bills won’t shoot up if a supplier increases its prices. But when the fixed period ends, companies often move customers onto their standard tariffs instead. A company’s standard tariff is usually the most expensive one it offers.

To help you avoid getting put on a pricier deal, we’ve rounded up the fixed energy deals that are due to come to an end this month. If yours is on the list, it could be time to switch.

To see how much you can save by switching energy suppliers, use our independent price comparison site Which? Switch to find the cheapest deal for your household. You can call Which? Switch on 0800 410 1149 or 01259 220 235

Switch your energy deal now and avoid exit fees

Your energy company has an obligation to let you know your tariff is ending 42 and 49 days before its end date. But, you don’t have to wait until the tariff has ended to switch, as suppliers are not allowed to change an exit fee during this time. 

If your tariff ends in May, you should be able to switch now and avoid any exit fees.

Energy customers in the UK are getting savvier about switching to a better energy deal. Energy regulator Ofgem says that between January and March this year over a million households switched suppliers. Around half of these moved to an independent supplier.
