One Energy Avis 

I wish I had read the reviews first! Just avoid at all costs, it will end up costing you.
After 12 months at auto renew they increased my prices from 5.12 to 7.12 for gas and from 22.67 to 32.22 for electric. Even though the price I had negotiated with British Gas Lite and Yu Energy was also set for 3 years at this lower price.
The way they work - they basically pay your bills for you and then invoice you. So you skip the supplier, trouble is they raise their price over and above what the supplier is charging It is a total con and illegal.
If you try to complain they ignore you, if you raise a query, they ignore you. They only contact you when you stop paying their prices.
Worryingly sent a complaint letter to their registered address as detailed on their website, it came back 'not know at this address'
I could write more about them but as I am in the process of taking legal advice I best not
Just please avoid.

The is not a bona fide company. They pose as an energy supplier but take your money and then don’t pass it on to the real supplier.
They are not registered with OFGEM!
When we cancelled our direct debit they set it up again.
They take money from your account without advising what it is for.
They refuse to prove accurate bills or statements.
We are currently taking legal advice to get our money back and expose this company.
AVOID AT ALL COSTS!

Well what can one say…

To leave this company 1* would be generous.
Despite their attempts to silence the campaigner behind Hands off My bills which is positively engaging with other affected clients of One Energy, most of the people who are also leaving 1* reviews have nowhere to go to feel supported because they are simply unregulated/cleverly disguised behind multiple companies. The campaigner has even tried to be silenced! They know the truth!

This is not a proper company. This is an unregulated enterprise whereby energy is resold under false pretences. The contracts are a sham- their invoicing methods ludicrous and if you don’t like it, they will start retrieving DD through the DD indemnity scheme from the energy suppliers despite you paying them for your bills if you query just a bit too much what they are up to.

Mr Francis and co should be ashamed. Targeting the vulnerable hospitality industry particularly to make profits.

Extremely disappointing!
We were notified by Engie, our electricity supplier, on several occasions that the Direct Debit arrangement had failed. As a result, we had to make additional payments directly to Engie to avoid disruption to our electricity supply.
Despite repeatedly raising this with One Energy, we received no response. We have also repeatedly requested a full account reconciliation, but this has never been provided.
Based on our own records, we believe our account is more than £10,000 in credit, yet we have received no satisfactory explanation or repayment.
One Energy trades under Exchange Enterprises Limited. We have been unable to find Exchange Enterprises Limited listed as a member of the Energy Ombudsman scheme, despite searching under both names. We have also noted that the Companies House record for Exchange Enterprises Limited currently shows a proposal to strike off the company.
Our attempts to resolve this matter, including a formal Letter Before Action, have gone unanswered.
Based on our experience, I would not recommend this company.

The 2nd negative review in 2 months.
For the second time in 2 months I have been sent a Disconnection warrant from my electrical supplier due to One-energy not paying my bill £3000 this time (at least it's lower than the last one £14000) Their excuse is the supplier is not allocating payment to the correct accounts. The trouble is my Gas supplier is also sending me overdue notices so both my suppliers have trouble allocating the payments to my account !!! I just dont believe one-energy and I can't wait to get away from them my exit window is 2nd July but I still won't be able to get rid of them till October!! Just don't go near them !!

I had a dealing with The Gas Company whose complaint procedure brought me to One Energy so I presume they are the same company. If this is the case, they are an unprofessional company. All their correspondent letter has no company address. Which says a lot about the services they are providing.

I would never be so unfortunate to deal with a company like these anymore in the future. However, I will be looking to take them to court to recover the over £9,000 that is stuck with them as exit fees. What company on earth takes direct debit twice a month and on top of that charges you over £9,000 in exit fees. Very ridiculous. Just want the public to be aware that this is not a good company to do business with

My account has been over charged by £2862.00 this month without my knowledge despite me paying my monthly agreed payments in full and on time. This is not the first time this has happened and I never get a satisfactory response from my so called account manager

Following on from my review posted on 16/10/25. After months of stress and aggravation, One Energy did refund the monies owed to me. Unfortunately, the nightmare hasn’t ended and though I thought it couldn’t get any worse, it has! Today, a bailiff representing an energy company that I’ve never heard of, attended my business to deliver a letter, explaining that my supply is going to be cut off! Strange considering that I have been paying One Energy for my usage without fail and have no outstanding balances. Clearly, they have been holding my money, instead of passing my payments on to the supplier. Now my staff think that the business is in trouble, unable to pay bills, their jobs are in jeopardy and I have the stress of wondering if and when they’re going to return to cut off my supply. One Energy are aware, but have not dealt with the so called “administrative” error. My experience with One Energy has been an absolute nightmare from the outset. The stress that they have caused my family and I is immeasurable!

One Energy have been brilliant. Friendly, reliable, and transparent from day one. It’s rare to find a company that delivers exactly what they promise

One energy has been nothing but helpful, I have had my business for over 20 years and never dealt with such an amazing team. Dealing with my gas and electricity accounts has never been more simple. I have recommended this company to a lot of other businesses in the area. The communication has been outstanding. Not once have I not been about to talk to someone instantly, being in the industry for as long as I have you’d know it’s never this easy. Just want to say a big thanks to the whole team.

Again one energy have been a breath of fresh air, getting me some exceptional prices for me renewal. Much appreciated 👍

Very good company. I do not have hours to spend on the phone to suppliers and trying to find renewal rate

My contract with one energy has just ended but I have chose to renew with them.

They’ve managed to save me a lot of money on my electric with my new contract. From 47p to 20.8p i am so relieved i can across one energy. I would highly recommend!

What makes One Energy's service better than all of the other suppliers that I have used is that I don't have to sit and wait on hold to speak to anyone. This in itself deserves 5 stars

I have been with One Energy for the last 6 months with no problems. I provide regular reads and the service is high quality from my own account manager who is based in the UK. No hold times and if she is already on a call, she always calls me straight back. Fantastic service.

Another 7 months have passed since my last review and I am still waiting on a manager to call me back.

I've rung and rung, been told it's 'been escalated' and nothing.

One Energy have now stopped paying bills entirely, leading to them now having taken our money, but our business receiving debt chase.

Exactly what Paul said on 16th October. We have a large amount of credit due and as a small business we need this paid back. Still ongoing but hoping it gets reviewed and paid back!!

Not replying to numerous phone calls. Have taken out over £2000 . Can not get it back.
Is causing me a lot of anxiety. Do not use these people

Great Service!
I have been with One Energy a few years now, they initially came out and discount my rates when I was in a contract which I was very pleased with. I have also just renewed with them as the rates were the lowest I could find. Great service very impressed.

All you have to do is read the reviews below

Edit nov 25: this company owed me over £1000 at the end of the contract. Whilst I was waiting for a refund a few weeks later took a further £2100. They’ve agreed to pay me back but have now been waiting over a week. Now seeking legal advice

This company takes over your energy account whilst your contract runs down. They set up a direct debit and starts to take money out of your account. Next minute you have your current provider chasing you for money with debt letters. The excuse was that they didn’t have the correct details. Funny how they sorted this without me sending any other details across. They will take money out of your account and you have to beg for an invoice, a lot of the staff don’t know the difference between an invoice and an account summery. You end up calling them to get through to a receptionist who will put you through, but there is no one ever available. Luckily my dealings with this sham of a company are over at the end of this month

Do your self a favour go direct or use a known broker

Where do i start?
Awful communication, they do not email to emails and are constantly in meetings or unavailable to talk. Take money off you on direct debit but do not hand this money over to energy supplier for month causing debt letters and all sorts of other messes to sort out. Set up contracts with the suppliers in all sorts of different names .. dodgy to me!
These brokers are meant to be helpful and take the stress away, these people cause the complete opposite.
