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.
Good Energy
Pros
- Renewable electricity at 100%, secured through ppa, sits behind the whole range.
- Tariff types run to fixed, variable and ev, adding a variable option to the fixed, time of use and ev set listed by Endesa.
- The EV kit is a tethered charger at 22 kW with installation included, and solar divert is supported.
Cons
- An exit fee of £50 applies, which places Good Energy at 22 of 29 brands ranked on exit fee.
- Fixed terms are 12 months, so the rate is protected for a short stretch only.
- Support runs on email, phone and help centre, with no live chat or member forum in the list.
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.
Good Energy
Who it suits
- EV owners in GB who charge at home overnight and want renewable supply from the same supplier.
- Households willing to accept a short fixed term and an exit fee in return for a low off-peak rate.
- People who want human help on email, phone and help centre rather than app-only self service.
Who should look elsewhere
- Drivers who want dynamic pricing: Powerpeers lists dynamic tariffs within dynamic, fixed and variable.
- Anyone needing a prepay option, which Electricity Ratings includes in fixed, ev and time of use but Good Energy leaves out of fixed, variable and ev.

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.
Good Energy
Does Good Energy supply gas as well as electricity?+
Yes. The fuel mix is electricity and gas, so the same supplier can cover both the electricity and gas side of a household. The company serves GB, which narrows it to a single market, and the tariff types on offer are fixed, variable and ev. Budgeting with the same supplier across both fuels usually simplifies the comparison.
What does charging an EV on this tariff cost?+
The off-peak rate on the Good Energy EV Charge tariff is £0.08, and that is the number to compare against other EV tariffs. Overnight charging is the point of the plan, so a household with a home charger and a normal nightly routine gets the benefit without changing habits. Charger and tariff pairing is listed as Good Energy EV Charge, so check your equipment matches before signing up.
