One Energy Reviews 

No communication! Robbing b. Won’t let me leave them. Don’t answer phones, don’t reply to emails. Raised with ofgem. Tried taking over £4K a month for a small pub just on electricity! Never taken a meter reading, changed my suppliers without informing us, I am suicidal because of the stress they are causing me since October 2024 and having to get help. Never go with them. I just want to leave, please.

I was put on a monthly direct debit plan initially, I then wanted a variable monthly plan (which they did), but I had to supply them with monthly readings via email as they don’t have a website to enable you to do this through. Then without asking put me back on a set monthly plan, which I don’t want and it will take 4 months to enable them to put me back on a variable plan
All I wanted was to pay for what I use on a monthly basis
When your contract is up and you want to swop suppliers be aware that they are not like other companies, who require a months notice, oh no, they require 90-120 days notice !!!!
Absolute nonsense of a company

AVOID, AVOID, AVOID.

Similar to other 1 star reviews, this company is a SCAM company, your promised 5% reduction & a claim back on historic water bills through Trilogy consultants that never materialise, your charged more than you we're paying then when you email/call your avoided like the plague.

Don't make the same mistake I have, avoid at all costs.

Read the other 1 star reviews, this company are the worst of the worst.

I could provide paragraphs of information about them and their unscrupulous behaviour, but I am sure they would try to get the review remove, or negate it with a "you signed a contract" comment.

Their day of reckoning is coming

I would give One Energy no stars if I could. DO NOT USE UNDER ANY CIRCUMSTANCES. You will be signing away any control you thought you had over your energy account. They take over your payments to the electricity company you are with, and they pay them months later - causing you problems with your credit rating. They are chaotic, delay answering your emails, and threaten you with collection companies when you are trying to get answers to your very valid questions.

Scam company. Do not use. Lots of sneaky overcharges, told outright lies to get us to sign up and then never provided us with a contract. Restarted a cancelled direct debit without notification or consent and then dodged our calls. Currently beginning the process of suing them for fraud.

DO NOT USE ONE ENERGY! They claim to give you 5% discount on energy you consume from the underlying provider but in reality they take control of your account with the underlying provider so you can no longer see your usage or the amount of money One Energy pay to them each month and then they charge you a direct debit above the amount they are paying to the underlying supplier. You have no idea as you can't see usage amounts and you don't receive any bills from One Energy. You pay well above what you should be and it goes in One Energy's pocket! Additionally, they can move your underlying supplier to another provider without even asking or telling you so sometimes you may not know who is actually providing your energy...they tell me this is in the small print. I have a few businesses which I used One Energy for in confidence that they would manage my accounts for me and make sure I am on the best tariff etc but sadly it has been a total mistake and I am now trying to get them to return tens of thousands of pounds which they owe me. I am also trying to take my energy accounts away from them so they can't steal any more money but they "renewed" the contracts after 12 months and I am now tied in with them for a further 12 months....which is also in the small print. Whenever you call or email One Energy they don't answer or return calls or emails and they have genuinely been the worst company I have ever dealt with in the 20 years I have been in business. Please please please beware, One Energy is a fraud and needs to be shut down.

Just finished with our pub, kept all our suppliers up to date with what we were doing and gave them all 90 days notice of what we were doing. Chloe dealt with our account for both gas and electricity for One Energy and as the title reads, we paid for the energy we used and had no surprise monetary values added. Overall we were Happy with how they dealt with us. Well Done

Took more money than I would have paid had I dealt with energy company alone and after months of wrangling have agreed to pay less than half the money they have taken ,oh and fined me for.leaving early as I had had enough of being ripped off. AVOID LIKE THE PLAGUE!!

Do not use this company
Have had nothing but problems since moving to them in October 2023
Taking more money than it would have cost to pay directly to British Gas even with there 5% discount
Have taken extra money from our bank account without prior notice
Will not answer my calls and never respond back to you by phone ot email

I have been paying this company since July 2024 for both my gas and electric. They have received around £15,000 in total and had been paying my bills. On moving out of the premises and issuing final reading they have requested all the money back from both suppliers leaving my accounts with my suppliers in £15,000 worth of debt which they are now chasing me for. I have called One-Energy and requested Brandon my so called account manager to call me... Still no call!! I have emailed.... No response!!!
My next step will be legal action to recover all the money paid to them including late payment charges and stress. DO NOT PAY THIS COMPANY A PENNY!!!

My thanks to Mark and his team from One Energy. I received great advice while prospecting for my business account, prices were competitive and follow up carried out promptly.

Been with One Energy now for a few months and it has been a seamless switch. James and Chloe have been amazing to work with.
Billing is easy to understand and payment is made easy so I dont have to worry about anything.
One Energy have really taken the stress out of dealing with my energy bills.
100% would recommend.

One energy supplies our electricity and the customer service is excellent. Mark, our contracts manager is always available for assistance when needed and happy to help.

Smooth transfer from our previous provider to one energy. Accounts managed well, with clear communication and a good service from Mark (accounts manager)

James and Chloe have been next level with our account, been with One Energy for 6 months and just agreed a new deal before the price increases. Our golf club would recommend One Energy to anyone who wants to pay a fair price and be able to speak with actual people who know what they’re doing. 5*

Great service. Excellent customer service

I've been very satisfied with the service provided by One Energy. The billing is clear and transparent, and I appreciate the reliability of the account managers. Customer support has been responsive whenever I've needed assistance. Many thanks!

Thank you, Emma, for your valuable assistance in managing our one energy account. Your support is greatly appreciated!

Very helpful in transferring from one provider to another. Fair pricing too.
