So Energy offers electricity-only and dual fuel tariffs to customers who don’t pay for their energy in advance. It puts customer service at “the heart of everything we do” and offers renewable electricity to all its customers.

So Energy was established in 2015 and sells only 100% renewable electricity as well as dual fuel tariffs. In 2021 it merged with ESB Energy to propel it into the top 10 energy suppliers list.

According to Ofgem, So Energy’s customers currently make up 1.1% of the electricity supply market and 1.2% of the gas supply market. This makes it the UK’s ninth largest energy supplier with over 300,000 customers in total taking gas (260,000) and/or electricity (307,000).

Customers have awarded So Energy an average of 4.0 stars on TrustPilot. As of May 2024, 73% of reviewers have awarded it 5 stars from a total of around 17,000 reviews. This places it 33rd out of 321 energy suppliers.

So Energy tariffs include electricity-only and dual fuel plans for customers who pay using Direct Debit or on receipt of a bill. So Energy doesn’t offer prepayment tariffs for those who pay for their energy in advance.

The company offers a simple choice of fixed and variable rate (So Flex) tariffs. Fixed-rate tariffs freeze unit and standing charge rates for 12-24 months but come with an early exit fee. You’ll have to pay this fee if you switch to another tariff more than 49 days before the tariff ends. So Energy currently charges £75 per fuel if you exit early.

So Flex tariffs are subject to Ofgem’s energy price cap, which sets the maximum amount suppliers can charge for gas and electricity. The price cap changes every 3 months – check out our price prediction guide to see what the current cap is, and whether it’s set to rise and fall in the next few months.

So Energy provides installation services for solar panels and batteries along with air source heat pumps. It also sells boiler and central heating cover plans.

So Energy only supports standard credit (smart or non-smart) meters. It does not support prepayment meters. Meters can be either single-rate or 2-rate, meaning Economy 7 plans are supported.

Yes, So Energy can fit a smart meter for free.

Yes, all of So Energy’s electricity plans are supplied from 100% renewable sources as confirmed by its fuel mix. However, it doesn’t own or generate any renewable electricity itself.

Instead, So Energy obtains renewable electricity by purchasing Renewable Energy Guarantee of Origin (REGO) certificates from UK suppliers. Each year, customers get to choose which type of suppliers – wind, solar, hydro or biomass – are used. The mix of electricity sourced from each supplier type is based on the proportion of votes each receives.

So Energy encourages customers with energy debt to get in contact to discuss ways it can help. Details can be found on its support pages, where options it offers include:

  • Discussing payment plans to spread debt repayments over a longer period.
  • Asking for a temporary reduction in monthly payments.
  • Discuss a final bill repayment plan if you’re switching.
