So Energy Reviews Summary
At a Glance Summary
So Energy is a UK supplier that puts green energy at the forefront, offering 100% renewable electricity on all its tariffs and a unique feature allowing customers to vote on the source.
Price-wise, its fixed tariffs are competitively positioned in the middle of the market, offering potential savings against the standard variable rate.
However, this focus on green energy is let down by consistently poor customer service scores.
The latest data from both Citizens Advice and Which? place So Energy at or near the bottom of their rankings, making it a supplier best suited for environmentally-conscious customers who are comfortable with a digital-first approach and are prepared to overlook potential service issues.
Who is So Energy?
Founded in 2015, So Energy is a small-to-medium UK energy supplier that successfully navigated the 2021 energy crisis.
Following a merger with ESB Energy, the company now serves over 300,000 customers across the UK.
So Energy’s core mission is to provide renewable energy and help customers lower their carbon footprint.
A standout feature is their commitment to customer choice, allowing those on fixed tariffs to vote on which renewable source (such as solar, wind, or hydro) their energy is generated from.
What tariffs does So Energy offer?
So Energy currently offers a straightforward range of tariffs, including fixed, variable, and specialist options.
Fixed-Rate Tariffs
So Energy has two fixed-rate tariffs, So Galloway One Year and So Galloway Two Year.
These tariffs lock in your unit rates for 12 or 24 months, protecting you from price fluctuations.
Both tariffs provide 100% renewable electricity and come with exit fees of £100 and £150, respectively, if you leave your contract early.
Variable-Rate Tariff
Their standard variable tariff is the So Flex.
The price of this tariff can rise and fall in line with the Ofgem energy price cap.
It has no exit fees, offering flexibility, and importantly, it also includes 100% renewable electricity.
Specialist Tariffs
For electric vehicle owners, So Energy offers the So EV tariff.
This smart tariff provides cheaper off-peak electricity rates overnight, designed to make charging your EV more affordable.
A smart meter is required to be eligible for this tariff.

What do other So Energy reviews say?
Customer feedback on So Energy is very mixed, with a clear split between positive online sentiment and poor scores in official surveys.
Trustpilot
On Trustpilot, So Energy holds a ‘Great’ rating of 4.3 out of 5 stars from over 24,000 reviews (as of September 2025).
A large majority (72%) of users give them a 5-star rating, often praising helpful customer service agents.
However, 13% of reviews are 1-star, with common complaints citing billing errors and smart meter installation problems.
Which? Energy Survey
In the most recent Which? energy survey, So Energy scored just 58% overall.
This placed them joint 15th out of 17 UK suppliers, with a particularly low assessment score of 52%.
This suggests that while some customers have good experiences, the company’s processes and reliability are rated poorly by the consumer champion.
Citizens Advice
The official Citizens Advice domestic energy supplier comparison, which uses impartial data, paints the most negative picture.
For the period January to March 2025, So Energy was ranked last (16th out of 16) with an overall score of just 2.2 out of 5 stars.
They scored particularly badly on the number of complaints received, with a rating of just 1 out of 5.
How green is So Energy?
So Energy has strong renewable credentials.
According to the latest fuel mix data, 67% of their electricity comes from renewable sources, which is well above the UK average.
Crucially, all of their tariffs for new customers provide 100% renewable electricity as standard.
Their unique selling point remains the ability for customers on fixed tariffs to log into their online account and vote for whether they want their energy sourced from solar, wind, or hydropower.
What is So Energy customer service like?
Based on official data, So Energy’s customer service performance is among the worst in the UK market.
The Citizens Advice supplier comparison for Q1 2025 shows they received 71.7 complaints per 10,000 customers, one of the highest rates in the industry.
The average call centre wait time was 4 minutes and 19 seconds, which is higher than many rivals.
While they did respond to 74.5% of emails within two days, their bottom-of-the-table ranking highlights significant service challenges.
What is the So Energy website/app like?
So Energy’s primary account management is done through its website, which is functional and allows customers to submit meter readings, view bills, and manage their tariff.
The company has an app available on the Google Play Store for Android users.
This app allows for basic account management, including meter reading submissions via the phone’s camera.
However, there is currently no app available for iPhone users on the Apple App Store, which is a significant drawback for a large portion of customers.
What billing options are available?
So Energy’s primary payment method is monthly Direct Debit, which is standard across the industry.
They do not offer payment by cash or cheque.
It’s also important to note that So Energy does not currently accept new customers who use prepayment (or pay-as-you-go) meters.
Does So Energy offer a recommend-a-friend referral scheme?
Yes, So Energy has a ‘Refer a Friend’ scheme.
When a customer refers someone who then signs up, both the existing customer and the new customer receive £50 of account credit.
This is a competitive offer compared to other suppliers’ referral schemes.
Who is So Energy good for?
So Energy is a strong contender for customers whose number one priority is green energy.
If you are passionate about renewable power and want a say in where your energy comes from, their unique voting feature is a compelling reason to switch.
Their fixed tariffs can also offer good value, making them suitable for budget-conscious environmentalists.
Who might So Energy not suit?
If you value responsive and reliable customer service, So Energy is probably not the right supplier for you.
Their consistently low rankings in official surveys by Citizens Advice and Which? point to underlying issues with their service and complaint handling.
Furthermore, customers who rely on an iPhone app for account management or use a prepayment meter will need to look elsewhere.
How does So Energy compare to its competitors?
So Energy vs Octopus Energy
Octopus Energy is a market leader in customer service, consistently topping the Which? and Citizens Advice tables.
They also offer innovative smart tariffs and excellent app functionality.
So Energy competes on its unique green voting feature, but falls far short of Octopus on service and technology.
So Energy vs E.ON Next
E.ON Next is a larger supplier with a similar customer service score to So Energy in the latest Which? survey.
As a ‘Big Six’ supplier, E.ON Next offers a wider range of services, but So Energy’s smaller size allows it to focus solely on its green energy mission, which may appeal to some customers.
Our Verdict
So Energy presents a clear choice for UK consumers.
If your priority is genuine green energy with a unique level of engagement, their 100% renewable tariffs and source-voting feature are hard to beat.
However, this comes at a significant trade-off.
With rock-bottom rankings for customer service from both Citizens Advice and Which?, potential customers must be willing to accept the risk of a frustrating service experience.
It is a supplier for the dedicated environmentalist who values green principles above all else.

How do I switch to So Energy?
The easiest way to switch to So Energy is through a comparison website. This will allow you to check if So Energy is one of the cheapest suppliers for you (tariffs vary based on your area) and will allow you to quickly and easily switch to them.
I had a contract with So Energy for many years and built up a credit balance. I asked them to refund the credit and they refused, repeatedly. Eventually I closed my account, making sure my account balance was zero and reported them to the regulator who agreed they should have refunded the credit balance and fined them £75. Which they paid. And to my surprise, a year later I found they have now put a notice on my credit file that I owe them money. Of course I’ve filed an objection at the credit agency. I recommend to stay well clear of this dishonest company who went downhill fast after they were acquired.
Our experience has been very similar to those above. Very difficult to contact them, we are still waiting to have our full electricity supply restored since February15th, but no success. Choose another supplier because the customer care is non existent .Will probably have to contact the ombudsman.
We have no problems with so energy. I contact them via email always respond. Great that it’s green. So much better than our last provider would reccomend to anyone.
I’ve been with So Energy for a couple of years now, and I can’t fault their customer service or their customer care. They undertook a complex solar panel and battery installation for me, and stayed in touch from quote, installation through to all the snagging and this was all done during the COVID-19 Pandemic – a very challenging time to get things done. They went above and beyond in ‘so’ many ways. They organised my feed-in tariff for my solar installation and organised a dual price tariff (so we can do power heavy activities like using the washing machine and EV charging) at night. They helped me to organise with the battery company to top up the battery during the cheaper tariff period and that helps us to keep our costs low when the sun doesn’t shine. When there was a problem accessing the Battery App, they organised a fix with the battery company so I didn’t have to. It’s a shame that some people here have been disappointed with So Energy’s customer service, so I thought I’d write this review to act as some kind of balance. I have no connection with So Energy other than being a customer.
I can’t fault this company, they have been 100% transparent and react to emails within minutes. They have been by far my best energy provider ever and the fact they 100% green is even better.
I have been with SO energy since September 2020 and not had any problems whatsoever. Easy to submit meter readings online! Bills are very clear. Surprised at all these negative reviews. SO Energy reduced my DD payment for summer and made it clear that is what they do. About to switch as 12 month contract ending and hopefully won’t experience any difficulty there either
It seems you people are having similar problems as me. After 10 months of me contacting them, my two rate meter is reading that I am using more fuel during the day than at night. In spite of several e-mails, videos, pictures and phone calls whoever I speak to just goes into script mode and rehashes what has been said before.
Ofgem website down this week due to maintenance and have contacted Citizens Advice as this has really gone on far too long.
Today my mission is to write to head office. Lets see if anyone there has the brain they were gifted with at birth!
So Energy are the worst energy provider that I have ever experienced. They offer no customer service at all. I have had no replies/response from them in the last nine months. It seems that all they want is the money, money, money. I don’t expect them to last long.
Don’t know how you are trying to get in touch with them but I spoke to someone on the phone only a few days ago
It took me when I first joined so energy 5 mins to get Through to them Now it’s taking 45 mins this very poor So energy are taking so many customers on that they do not have the staff to cope.. Very very Disappointed I will be changing my provider
So Energy.. At the Beginning this company was superb now its very poor in trying to get through to them
I need to know how to send my meter readings. Trying to phone and getting nowhere.
I have been with So Energy for a while but when I had a problem with the smart meter they asked to fit I saw their true colours. SO Energy would not respond in any meaningful way. I was given inaccurate (untrue) information and my emails and calls were completely ignored. Exasperated, I emailed their head of customer services but still no response at all, so I will now be reporting to the Ombudsman.
I think SO Energy Customer Services has taken the “Ryan Air” approach so I’ll be leaving them as soon as I can – my advice is AVOID!
Terrible business I wouldn’t recommend to anyone. They didn’t update my direct debits after their estimates had been way off despite the fact I had submitted meter readings. This resulted in being undercharged by 50% and then they require the entire amount to be paid before the switch is made. They also tried to say I hadn’t called to request an updated direct debit but my call records from my phone company prove that I do.
I must say my experience exactly matches yours, Patrick. We were under billed and under quoted after SO failed to update our account for over a year after the provision of a reading. They refused to be accountable in any way for their serious failings. I could not leave them quick enough as they cannot be trusted, but like you, SO blocked me moving providers until they have all the money they demanded paid even though there was a live and genuine dispute about it.
