Will your annual energy bill rise by £400 from July?

Revealed: the 17 gas and electricity deals ending that will increase your bills

Don’t let the sunshine leave your energy bills in the shade. Gas and electricity deals ending this month are set to cost customers more than £400 in a year if they take no action.

First Utility customers who do nothing will be hit by the biggest energy bill increases when their fixed deals end in June, our research reveals. One deal ending will add £404 to customers’ gas and electricity bills over the next year if they don’t switch when it finishes.

Of the 19 dual-fuel deals ending in June, 14 of them will add more than £200 to your energy bills over the next year unless you switch. Six of the deals ending are from Big Six suppliers. Nine are from First Utility.

When your fixed energy deal ends and you do nothing, you’re automatically rolled onto your supplier’s standard tariff. This is often its most expensive deal.

So check below to find out whether yours is one of the energy deals ending this month. Then read on for the cheapest five energy deals available now – and how much you could save.

Switching to a new, cheaper, energy deal is easy. Don’t just take our word for it –  87% of switchers* say the same. Use our independent switching service, Which? Switch, to compare gas and electricity prices. Or you can phone us on 0800 410 1149 or 01259 220235.

Other gas and electricity deals ending in June

Other energy tariffs that are ending this month, but would increase your annual bill by a smaller amount, are:

EDF Energy Blue+Price Promise June 2017 – Paperless, First Utility EHL Fixed June 2017, First Utility iSave Fixed June 2017, First Utility iSave Fixed June 2017 v2, M&S Energy Fix & More Jun 17, Npower Price Fix June 2017, Sainsbury’s Energy Price Promise June 2017.

Two other British Gas deals are also ending (HomeEnergy Capped Jun 2017 – Paper and Paperless and HomeEnergy Reward Jun 2017 – Paper and Paperless) but neither will result in a bill increase if you take no action, since they’re the same price as British Gas’ standard tariff.

But it’s worth keeping an eye on your bill, as British Gas promised it would freeze its standard gas and electricity prices until August 2017, so it may then choose to increase prices.
