Our verdict on each
Eon Next
Eon Next suits households that want several tariff styles and a solar or charger-friendly setup, and it holds a reference annual cost of £166. The trade-off is the exit fee of £25, which matters if you might move supplier early, so compare the term length before you join.
Ma Petite Facture
Ma Petite Facture suits French households that want renewable electricity and a supplier they can leave without penalty, with renewable content of 100% at an exit fee of €0. The trade-off is commitment: fixed terms run 12, 24 and 36, so a longer block is the price of locking the rate.

Pros and cons
Eon Next
Pros
- Tariff types run to variable, fixed and tracker, a wider spread than Endesa, which lists fixed, time of use and ev.
- Fuels cover electricity and gas, so electricity and gas can sit on the same account.
- Renewable electricity accounts for 27.3% and solar households are paid an export rate of £0.15.
Cons
- Leaving early costs an exit fee of £25, and Eon Next ranks 21 of 29 brands on that measure.
- The unit rate of £0.32 sits at 20 of 23, so the headline rate is not at the front of the table.
- Support runs on email, phone and help centre only, with no live chat channel listed.
Ma Petite Facture
Pros
- An exit fee of €0, ranking 1 of 29 on that measure, keeps switching cheap.
- Tariff types run fixed, variable and green under a single supplier, and fuels cover electricity and gas for a dual fuel household.
- Renewable content of 100%, made good through certificates.
Cons
- Renewal is the sharp end: prices after a fixed term in this group sit at €29.40, while entry prices list at €23.03.
- Fixed terms run 12, 24 and 36, so a longer block means a longer wait before you can move or renegotiate.
- The supplier operates in France only, which narrows the comparison to a single market.
Who each suits
Eon Next
Who it suits
- Households served in GB with rooftop solar or a home charger, who can use the export rate of £0.15 and an off-peak rate of £0.085.
- People who want tariff types to include variable, fixed and tracker so they can change style of plan later.
- Anyone comfortable with a reference annual cost of £166 alongside an exit fee of £25.
Who should look elsewhere
- Shoppers after a green tariff, since Electricity Ratings lists fixed, ev and time of use and Eon Next does not.
- Households that want a prepay option, since Eon Next covers variable, fixed and tracker while Endesa offers fixed, time of use and ev.
- Buyers who expect a cheap exit, since leaving early costs £25 and the brand ranks 21 of 29 on that measure.
Ma Petite Facture
Who it suits
- Households in FR that want renewable supply: renewable content is 100% and a smart meter is not required.
- Dual fuel households, since fuels cover electricity and gas.
- Anyone wary of early exit charges: the exit fee is €0 on fixed terms of 12, 24 and 36.
Who should look elsewhere
- Households that want a prepaid tariff: electricity-ratings lists one in fixed, ev and time of use, which is not among fixed, variable and green.
- Anyone after a dynamic tariff: Powerpeers lists that type in dynamic, fixed and variable, which the fixed, variable and green range here does not cover.

Questions about each
Eon Next
What does Eon Next cost on a typical year of usage?+
The Next Optimise tariff is listed at a reference annual cost of £166. That is the headline figure to set against other suppliers, and on this comparison Eon Next sits at 1 of 4 brands ranked on that measure. Your own bill will move with your usage.
Is there an exit fee if I leave Eon Next early?+
Yes, leaving early costs £25. On that measure the brand ranks 21 of 29 brands in the comparison, so the fee is worth setting against the headline price before you commit to a term.
Ma Petite Facture
What will the electricity cost at the start, and what happens at renewal?+
Ma Petite Facture's fixed plans hold a unit rate for the length of the contract, which runs 12, 24 and 36. Across suppliers in this group, entry prices list at €23.03, and prices once a fixed term ends sit at €29.40. Ask for the renewal rate in writing before you switch, because the entry figure is the one that reads lowest.
Is there a fee for leaving early?+
The exit fee is €0, and the brand ranks 1 of 29 on that measure, so leaving does not carry a penalty charge from this supplier. Your current supplier's terms are a separate matter: check whether your existing contract carries an early termination charge before the switch date, because that fee is set by your own contract.
