With Energy Omdömen 

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

Extremely poor services! Been living without the hot water and cold radiators this winter!! The temperature outside is running is minus and we are freezing inside our homes.
This is ridiculous and needs to be fixed asap.

Repeated outages, tariff switches, outages to my property and to the development on which I live. No record of servicing of heating system. Repeated outages to hot water and heating outages that have lasted over 18 months and still not resolved.

Reported to Energy Ombudsman. Avoid.

Can’t imagine a more dysfunctional business that has actually been trading for so long. Luckily they are benefitting from the rise in the cost of living. I’ve live in a new build property for 5 years. On average the entire building is without heating or hot water every 2 months. We have even been told that an entire block without heating/hot water was not an emergency because a tenant child was 6 years old and not under 5! We are without heating in minus 3 degrees and still won’t provide a fix.

The team was understanding and for a long time service wise in the UK the offered a bespoke package which fit my budget and requirements.
Highly recommended
Thank you Emma and team

They increased my bills from 40 pounds to 119 pounds this month saying that my consumption has not changed but there are rises in price. I have not used the heater yet!! I live on my own in one bedroom and imagine that I will be expected to pay more than 200 pounds for hot water and heater bills when winter hits and I start using the heater.

My advice : avoid completely. You will be robbed!!!

Our customer service experience was excellent. The team that handled our query were professional, thorough and most importantly thoughtful and considerate in dealing with our queries. I always come away feeling listened to and that every detail has been explained fully. A personable team. Thank you.

Great customer service experience. Proactive and professional!

Avoid them, they are not honest, when you put them on the spot with evidence that they are overcharging you or charging for services that we are not suppose to pay, they ignore the customer's messages. I have been asking to speak to the ombudsman, they simply ignore my request. I have been fighting them for more than a year now. They have changed my account without asking my permission, even though I had written an email saying I do not accept the changes on the account. They are trying to change my account so they can try to get away with back charging me the wrong amount. Very corrupted, I have no other words to describe this company. Stay away.

Very helpful over the phone and lovely service

Outages have happened often with our shared boiler and with energy have taken hours and sometimes days to react to them and fix the issue. They are not a large enough company with a large enough support network to fix issues quickly and the customer service is shocking. Avoid at all costs

They can't fix a simple problem with faulty meter reading that is not sending any readings to them. Instead they still charge me every month an account fee even if it's a zero usage. I complain, I ask to fix it. I'm horrified thinking how much they going to bill me once they fix the issue. But the issue is not sorted for 2 years. I can't even switch this supplier because I live in a newly built apartment

Worst provider. The hot water and heating in westmark tower is perpetually broken and it is freezing in December.

I find it incredibly expensive given that my standing charge is always higher than my consumption. So much water is wasted when running the water, waiting for the hot water to kick in. For what is supposed to be an energy saving/sustainable/environmentally friendly system, it seems to be very expensive for a water-wasting, temperamental system where you’re constantly in a game with the hot water, playing with the taps to get it to switch on. Claims to be low-cost but quite the contrary. In the summer months when no heating is being used, the bills have come to just over £40/month. I dread to see what the winter time bills will be like.

A hopeless company with incompetent staff. Have had two bills with only standing charges and not the usage. I guess I will be receiving a massive bill once they get their act together hopefully this year. Called four times in the space of two weeks and always get a promise of a call back that never happens. Filled online complaints form and nothing as well.

The property has a smart meter so there shouldn't be an issue however they can't even input the readings manually. I mean this is the highest point of incompetence in my opinion. I guess they have the monopoly as they are the only suppliers we can have so they don't really care. Maybe consumers like us should form a petition or something as this monopoly is just not right.

I cannot explain my experience with Withenergy, as i do not know what it is that they are billing me for.
Communication is terrible, even at Director level. I have been dealing with a complaint for 5 months now and have been promised calls back numerous times, which never actually materialise. I am being billed for a service that has never been explained to me and can;t actually view any bills for the period they are claiming i need to pay for. Also, the website is actually telling me not to pay my bills. As you may appreciate, this is a mystical company that has no answer to customer complaints.

Just like what Mike wrote.
"Was forced into a contract with this company upon buying a new property (was informed at a later stage that we cannot switch to a different provider).
Poor experience thus far (10 months): poor communication, occasional hot water shortages, all with a sprinkle of a massive monthly service charge. Suggest a hard pass, if you have a choice."
I will just add that there is no off hours service.

2nd update Jan 2025: they now asked via trustpilot for personal details. I refused as I highly suspect this is a pure bullying exercise (that trustpilot should not allow). If withenergy wanted to resolve these issues they would have already done so via the complaint (which been raised) channels. If withenergy wants to dispute having these issues, or want to offer a way for individuals to disconnect from their services, they can respond publicly.

Update: Jan 2025, after five years WithEnergy decided to dispute that this review was about them, I’d re-iterate again, it is very much about them, we still have about over 5 failures each year. And a constant ping pong game between them and the building management. All I wanted was hot water, instead I’m busy reporting failures (as they only dispatch an engineer after a threshold of calls), raising complaints with them, and required to make manual payments as they can’t even operate direct debit properly. Hot water, that’s all I wanted. And there’s no way out, not as individuals, and not as a resident majority.

Original review:
WithEnergy running the service for our a-bit-over one year old development. For the last year we had over 10 occurrences of failure in our district heat unit at peak hours. And although With Energy charging us monthly (A very high price to my opinion) - they only forward our complaints to the freehold installer as the system is still within their warranty.
We as residents been told we cannot change the supplier, and that they're doing the best they can, and cannot give us any compensation - hence no one has the interest of actually fixing the issue.

Expensive & Worst Experience. Don't go with With Energy. Their Customer Service is rude and only answer we get is we are looking into it. Faced frequent Hot Water Issues
