Pros and cons

Pros

  • The green tariff is 100% renewable, backed by a ppa arrangement rather than a certificate claim.
  • Households with solar are paid £0.045 for exported power.
  • The range runs wider than Powerpeers on tracker and EV tariffs, since So Energy Residential Energy lists fixed, variable and tracker while Powerpeers lists dynamic, fixed and variable.
  • EV drivers get an off peak rate of £0.075 alongside the other plans.
  • Smart meters are required, so usage data feeds the tracker and EV pricing.

Cons

  • Leaving a fixed plan early costs £75, which is a real cost for renters who may move house.
  • Support runs on chat and help centre, so there is no listed phone line for urgent meter queries.
  • The green and EV options are extra plans to weigh, not one combined tariff, and fuel choice is limited to electricity and gas.

Who it suits

  • Households in GB with solar panels who want an export payment of £0.045 alongside a green tariff.
  • EV owners who can shift charging to an off peak rate of £0.075.
  • Renters willing to accept an exit fee of £75 for a fixed term of 12, 18 and 24 months.

Who should look elsewhere

  • Renters likely to move during a fixed term, who would face an exit fee of £75.
  • Households that want a phone line, since support runs on chat and help centre.
  • Anyone outside GB, because the provider's markets are GB.

Plans and prices

So Energy Residential Energy sells fixed, variable and tracker tariffs to GB households, covering electricity and gas. That spread matters next to the alternatives: Powerpeers lists dynamic, fixed and variable, and Enddesa offers fixed, time of use and ev, so tracker pricing and an EV rate are harder to find elsewhere in this group. The fixed plans run for 12, 18 and 24 months, and ending one early costs £75. For households with an electric car, the EV tariff sets an off peak rate of £0.075, which rewards charging overnight rather than at peak times. A smart meter is required, so that rate and the tracker option depend on metered data rather than estimates. Variable pricing is there too, which gives a way out if the fixed term no longer suits once it ends.

Core features

The green tariff is 100% renewable, and the basis is a ppa arrangement rather than certificates. For households that generate their own power, exports are paid at £0.045, which turns a rooftop solar installation into a small income stream. The provider serves 300,000 customers, a base large enough to suggest an established operation rather than a small new entrant. A smart meter is required across the plans, so readings arrive without manual meter reads and the usage data feeds both the EV and tracker options. Taken together, the green supply, the export payment and the smart meter requirement point to a supplier built for households that monitor their own consumption closely.

The company behind it

The company trades as So Energy Trading Limited and is based in the United Kingdom, with its markets listed as GB. It was founded in 2015, so it has been trading for a while rather than being a recent arrival to the GB market. Support runs on chat and help centre, which means chat and a help centre rather than a phone line. For anyone weighing a move, the name on the contract is the trading company itself, which makes it straightforward to see whose terms you are agreeing to.

Frequently asked questions

What does it cost to leave a fixed plan early?+

The fixed rate carries an exit fee of £75. If you are renting, or expect to move before the term of 12, 18 and 24 months ends, that charge is worth adding to the price you compare. A variable or tracker tariff avoids committing to a fixed term in the first place.

How green is the green tariff?+

The green tariff is 100% renewable, sourced through a ppa arrangement. That means the renewable claim rests on a long-term supply contract rather than on buying certificates for the electricity already sold. The green option is one of the fixed, variable and tracker available.

Do I get paid for the solar power I export?+

Yes, exports are paid at £0.045. If your panels generate more than you use, the surplus earns a payment rather than costing you. You would also want to check how that export rate sits alongside the green tariff and the £75 exit fee on a fixed plan.

Is a smart meter needed?+

A smart meter is required for the tariffs listed here. In practice that means readings arrive on their own, which is what lets the EV tariff price charging at an off peak rate of £0.075 and the tracker option follow actual usage. Worth confirming before you switch if your property has no meter in place.

What is the cheapest way to charge an electric car?+

The EV tariff prices charging at an off peak rate of £0.075, so shifting charging to overnight hours lowers the cost of each unit. It is one of the fixed, variable and tracker on offer. Powerpeers does not list an EV tariff among dynamic, fixed and variable, which is where the difference shows.

Can I contact a human by phone?+

Support runs on chat and help centre, which is chat and a help centre. There is no phone channel listed for this provider, so if you want a spoken line for a meter query or a move, check that before switching. The help centre is the main route for account questions.

Who am I actually contracting with?+

The contract is with So Energy Trading Limited, which is based in the United Kingdom and was founded in 2015. Its markets are listed as GB, so the GB is the only place these tariffs are sold. It serves 300,000 customers.

Which tariffs are on offer?+

The lineup is fixed, variable and tracker, covering fixed terms of 12, 18 and 24 months as well as variable, tracker, EV and green options. Fuels are limited to electricity and gas, so both electricity and gas are covered. For comparison, Enddesa lists fixed, time of use and ev and Powerpeers dynamic, fixed and variable.
