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.
Rabot Energy
Pros
- An exit fee of €0 places Rabot Energy at 1 of 29 brands ranked on that measure, the strongest of its three placements.
- Green supply of 100% on a certificates basis, and a smart meter is not required, so the green option needs no new meter.
- Tariff types run dynamic, fixed and ev, putting fixed, dynamic, EV and green with a single supplier.
Cons
- A unit rate of €0.27 ranks 14 of 23 brands on that measure, so Rabot Energy is not the cheapest per unit here.
- The standing charge of €15 ranks 9 of 16, and it lands on the bill whatever you consume.
- Supply is electricity only, electricity, so a household that also holds a gas contract needs a second supplier.
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.
Rabot Energy
Who it suits
- Households in DE that want a green electricity tariff with a full year of fixed pricing and no exit fee.
- Drivers and EV owners, since dynamic, fixed and ev includes an EV tariff alongside fixed and dynamic.
- People who would rather not arrange new metering: a smart meter is not required.
Who should look elsewhere
- Anyone set on a variable tariff: Powerpeers lists dynamic, fixed and variable, and variable pricing is not in Rabot Energy's dynamic, fixed and ev.
- Households that want prepay or time-of-use pricing, both of which appear in fixed, ev and time of use.
- Buyers shopping mainly on the price per unit, given the mid-table position at 14 of 23.
