The exclusive Ecotricity EcoFixed - MS 1 Year May 26 v2 is 3.8% LESS than the current Price Cap on average (and roughly 15% below where it'll rise to in July) including £20 MSE dual-fuel cashback. Very few suppliers are offering fixed energy deals below the current Price Cap right now, so if you're risk averse and want price-certainty over the next 12 months, this looks like a good deal.

There are only 7,500 dual-fuel switches available (ends Fri 5 June 5pm).

• New and existing customers can get it (existing customers will have to pay exit fees if switching from a fix).

• It's a fixed-term tariff for 12 months.

• It's for dual-fuel, electricity-only or gas-only.

• There are £75 per fuel exit fees.

• Smart meters are required.

• You'll need to manage your account online.

• You must pay by Variable Direct Debit (can request fixed monthly Direct Debit after switch).

• You get £20 dual-fuel MSE cashback (£10 for single fuel).
