the team at MoneySavingExpert.com (MSE.com) has reported that several energy firms are now offering existing customers fixed-tariff deals which could give households a bit of financial stability over the next 12-months. Octopus, Sainsbury's Energy, E.on Next, Shell Energy and British Gas are offering deals that are just below, or on, the level of the current price cap (£2,074) - something MSE.com said “could be worth considering”.

But it also reminded people of its founder, Martin Lewis' ‘rule of thumb’ over whether you should switch to a fixed-energy tariff.

For the current fixed-tariff deals available to view on MSE.com, the consumer champion said: “Based on current predictions, if any firm offers a fix for under the July Price Cap, that looks a decent deal. If it's the same or a little more, it may still be worth considering for the sake of price certainty.
