Martin Lewis energy tariff fix 'rule of thumb' as several firms offer new deals

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.
