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.

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.
Octopus Energy
Pros
- Exit fee is €0, so a fixed term can be left early without a penalty
- Green tariff is backed by 100% renewable supply on a certificates basis
- Tariff choice covers fixed, variable and green on both electricity and gas
Cons
- Fixed terms run 12 months and then need a renewal decision, since no separate renewal price is set out
- Unit rate of €0.17 sits mid-field, so it does not undercut every rival on usage
- Tariff list covers fixed, variable and green only, with no time of use or electric vehicle option as listed
Who each suits
Eon Next
Who it suits

- Anyone comfortable with a reference annual cost of £166 alongside an exit fee of £25.
Who should look elsewhere

Octopus Energy
Who it suits

- Households that want a green tariff on a certificates basis at 100% renewable supply
- People who prefer fixed pricing but want an exit fee of €0 behind it
