With Energy Avis 

This is the first company that ever gained my second negative review.

5 months after closing my account,
I received a shocking bill via email claiming I have a balance of nearly £400 carried over from their old system.

It's absolutely nonsense as DD was set and bills were paid on time every single month.
I have double-checked those transactions with my bank and confirmed the closing bill should be only around £2.

Of course, I won't be paying this bill and I have immediately cancelled the DD.
If I missed that email, they would have stolen £400 from my bank account.

WithEnergy is the heating/hot water provider for our apartment complex in NW London (Park Royal).Below are my observations:
1) They change the billing system too often and have made the billing system deliberately opeque
2) They have a horrible bill tracking mechanism i:e some month you get massive bill while other months it’s extremely nominal
3) They have the same reply ‘We are facing some technical issues at the moment and your billing will be fine from next month’, this is the reply we are getting since last 2 years. I’m intrigued how are they even allowed to be a supplier for heating.

With Energy supply heating and hot water for our building. Over the 2 years of being here, they have changed their billing process 3 times! Each time changing dates, amounts, and payment methods, making it near impossible to budget accordingly as you have no idea when payment will be taken. Currently, due to their latest change, previous months bills were not taken, so we will be charged 3 months worth of energy consumption throughout August. Unfortunately we are stuck using them, I can very confidently say if we could leave I know our whole building would promptly go! With Energy you are utterly USELESS!

Back in April my account moved to the new portal and since then I have only managed to log in once.
Eventually I was informed that it isn’t working with iOS which, given the amount of iPhones being used, is ridiculous.
The IT department are supposed to be working on a fix but it’s been two months so far which suggests to me they can’t fix it or they need a better IT department.

Constant problems with bills since the migration to the "new" portal (the old one actually worked better). As others say, calls go totally unanswered, emails not responded to, including formal complaints. Absolute cowboys...

Awful company. So many issues since we moved into Regency Heights Park Royal. Two christmases in a row with no hot water or heating, With Energy ‘working on the problem’ on both occasions with no update to the customer. Regular outages. Some months we receive a bill of £5, other months it can be £300. No one at the company cares or seems to want to help.

Truly awful, complete lack of visibility on what my usage is or what tarried I’m on since they’ve moved systems. No one replies emails or resolve this on the phone. Furthermore, they have a monopoly in my development and we can’t use an alternative supplier, surely this should be illegal!

The accounts are completely messed up, payments are not up to date and you can’t get any info on their status simply because no one will reply you. It’s been 2 months that I try to fix this issue but I’m basically writing emails to a silent mailbox and wasting time over the phone… All of that happened after the migration to the new portal.

PLEASE AVOID AT ALL COSTS.
I am currently living in Marquess House a new built for renter apartment, and this company is the sole provider of heating and hot water which I find quite ridiculous as we do not have another choice. Why are they the sole provider of heating and hot water to all this New built at Regency Height Park Royal? I have been charged increasing bills regardless of consumption. I stopped using the heater but they still charge a standard service for nothing. I have reported them to Energy Ombudsman and also written to my local MP about this company. Surely as residents we should come together to petition and be given more choice of other companies to deal with. I am trying to move out very soon and will definitely avoid homes equipped with their heating services.

This company is the definition of robbery! I have been charged increasing bills every month, regardless of consumption. I always get insanely high back-bills for “cooling” even during the coldest months of the year, December and January! Who on earth will turn on the cooler during those months! I was even away for the holiday Christmas, yet my charges were higher than I was at the apartment. The last bill I got included back bills for cooling of £190 for December and January! How on earth is that possible when I was away all Christmas, and never turned on the cooler once? When I asked for a breakdown of day to day consumption, they refused to send for the cooling fare, and they always avoid answering my questions. Takes them forever to reply to my queries.

Lastly, their agent EMMA, who is the worst customer service agent I have ever seen in my life. She hangs up the phone while I am speaking, never calls back, and never answers when I call back. This company is a big NO, TRY TO AVOID AT ALL COSTS. I have been robbed enough, and I will stop this.

With Energy have been one of the worst customer experiences I’ve ever had. Do not trust them at all.
Our usual monthly heating bill was around £110 a month for a 2 bed apartment. Suddenly we got a bill for £660 and when I questioned them on this they did nothing to help and took over 2 weeks to offer any type of reply and at which we got another bill for £380 where we turned out heating off to prevent any high bills. Shocking service and could not recommend them any less

Baronet residents suffer from hot water supply disruption during this winter too often because of technical problem.

I feel that WithEnergy's hot water supply service falls short of a reasonable acceptable standard n is far from professional,!

Terrible. Raised rates and are not delivering. This is the fourth day in around 6 weeks that we are without hot water. No hot water means no showers, no heating, no washing machine, no dishwasher.

Just moved into a new apartment serviced by this company, however the hot water/ gas provision service has been poor. There has already been several breakdowns in supply in the heart of winter and the response times are not good enough considering the numbers impacted am during a break down. Wouldn’t recommend

Probably the worst energy company ever. I was not billed for the entire year - they claimed there was a fault which they never bothered to resolve. I chased for months even after I had moved out 2 months earlier. Eventually was sent a bill that did not match the energy I consumed and was made to chase them again which till today they have not responded nor sent a final bill. Corporate Criminals. (Viscount House, 8 Lakeside Drive - London)

Like every one else is saying, really high charges and we constantly lose hot water. It's below zero and we have to shower in cold water.
It takes them forever to fix issues.
It's a new building, there shouldn't even be issues at this point!!!
Shameful.

Honestly I never had such a bad experience with this company. They run the hot water to all Regency Heights Park Royal and in one week around 9 buildings have not heating and hot water for 3 days. Hot water for a shower and to be able to use our radiators. We are freezing in our flats and the customer service just say that they are working hard to fix the issue. We are more than 500 families living in freezing flats. But they still charge a standard service for nothing. Be careful with this company irresponsible

Loss of heating-so no hot water and heating in the flat for hours for days at a stretch during peak cold weather in December in London. Customer service have proved ineffective despite calls regarding the same complaint for multiple neighbours as well
