Calisen Omdömen 935

Just had a very last minute cancellation by the engineer advising that they didnt have stock of what was required to change my meters to smart meters. I'm sorry but all they do is change peoples meters to smart meters so how can they not have stock on there van! They must have known how many jobs they had for the day so why didn't they message me in the morning. Then at least i wouldn't have wasted a day waiting in! Absolutely terrible service and total disregard to people's valuable time.

After a call from Scottish Power asking me to book for an Electricity smart meter to get fitted I made an appointment on 17/12/25 for a meter to be installed between 10 and 2 on 07/01/2026. I’ve been waiting for a couple of years for this as so far Scottish Power have said they can’t install a smart meter at my address. Got texts and emails from Calisen confirming the appointment then today after clearing access and waiting at home, I got a call from them at 1pm to say engineer not coming and earliest reschedule they could offer is 28/01/26 - 3 weeks away. As soon as I agreed to the new date he hung up, no apology! Why are Scottish Power and other suppliers still using this incompetent supplier???? Having no smart meter is costing me a fortune as I am not able to get on an EV tariff until the meter is fitted. Will update in 3 weeks if they turn up then but from reading other reviews I think my pain is just beginning!!

Had smart meter installed all seemed well, however it turns out no readings being sent to my electricity provider and I cannot read the meter the low cost night rate has disappeared.
My electric company have raised the issue but no action other than a phone call asking me to take a reading.

Awful customer service. We've had two meter readings cancelled after the allocated appointment on the day. This means waiting at home and rearranging my working day and fitness classes on both occasions. On an earlier occasion, they refused to turn up when we had arranged a concierge with access to the meter and also access to our flat. The engjneer was very rude on the phone despite the concierge already being in our flat.

Refused to changed my gas meter to a smart meter twice over the past couple of years due to a small gap in the floor boards, they said if they touch it then the whole street would ‘blow up’. Had a gas engineer round to service boiler and fires and he said it’s an excuse as ‘meter maids’ can’t be assed with the job. My gas supplier constantly knocking asking me to upgrade to a smart meter, I reluctantly booked in with Calisen again 5th Jan 2025 8am-12 and took time off work unpaid. Got a call at 11:50, 10 minutes before appointment slot ends to say they were unable to make the appointment due to adverse weather conditions. I said they could have let me know sooner so I could have made it into work but apparently ‘the weather has just happened’. She gave me a date of the next available appointment I explained I was working and will not be taking time off again for these useless appointments. She was very passive aggressive and offered me a Saturday which I again couldnt do. Then she asked me my available dates which I gave which she couldnt make an appointment for. She then patronised me and said oh take it back to your supplier and get it rebooked with us

Amazing service from Vin 🌟. He came to sort an issue out with my gas meter last week and he has gone above and beyond to help me when i had another issue with my electric having no supply.
He communicated with me directly to resolve my meter issue and he arrived to me very quickly so im not left without power for long . 5 star service i cant be happier

Great service on new year eve no power just called up Scottish power within 1 hour engineer arrived excellent engineer Vinay got us back on supply within 45 mins thank you so much calisen for great service my family so much appreciated it!

When you’re driving on the busy M25 and you are driving next to one of their drivers scrolling on his phone for 20minutes straight is an absolute disgrace!

Appointment made for 22/12/25 on 19/11/25 between 12:00 & 16:00 hrs. I called to confirm appointment morning of 22/12/25 to someone who appeared to have just got out of bed. I called again at 13:30 hrs to ask what time engineer would arrive. I was told engineer had just arrived at job before me but I was next. Calisen called me at 15:40 hrs to cancel. I am furious as I have been unable to be productive today waiting for this pathetic Company!

company employed by British Gas in my case to replace a smart meter that hasn’t worked for three years.
Three appointments made, time booked off from work only for appointments to be cancelled the afternoon of the day before as engineer will not be able to make the appointment.
New appointments made each time until the last when I said forget it as had to make new appointment there and then on cancellation phone call, said I was working and not convient to agree a new date and could I ring back? Was informed that this was not an option and would have to call British Gas for a new appointment.
Will continue to poke button on meter with a long stick to bring it into life, take a photo on phone then zoom in to get the reading and submit manually on the British Gas app.

Why any provider would use these is baffling to me! Utterly incompetent, I don’t know whether they can do their job as getting them to actually attend scheduled appointments is impossible!

This lot had us wait in only to cancel at the last minute.
We rebooked and they cancelled again without discussion.

If these cowboys are installing your smart meter..don’t build your hopes up.

Cancelled, no one showing up or even cancelling 30 mins before the slot ends in same day of booking. I have been in this process for 6 months now still with mo gas meter reading working. Continously cancelling, I don't this I will ever solve this, the worst part is that you can't hire anprivate person to carry on the work...

Absolutely useless had a gas meter exchange booked today. Never turned up. Rang up they said the installer rang and left a voice mail and text message and rang me to say he was on an emergency call out. No phone call was received no text or voice mail either. Useless.

3 appointments missed so far for smart meter installation, each time I go to the back of the queue for another appointment. 3 times taking time out to be there, moving stuff around for access. Costing me a fortune as I am not able to get on an EV tariff until the meter is fitted. Each time excuses. They threaten to charge you £40 if you are not in or cancel with less than 24 hours notice but not willing to pay the same in compensation when they are at fault. I wish it were possible to give 0 stars.

I also wish I had read these reviews before contacting this company via Scottish power.
This company is diabolical I too waited in for hours with a no show from this company now book again for January, but I won’t hold my breath.

Came on here to see if it was just us having this terrible experience and I think I'm relieved to find we're not alone.
Today was our 4th cancelled smart meter installation appointment - generally recieved a call or text right at the end of the four hour slot. Have scheduled another but little hope they will turn up. Thankfully it's not too much trouble to wait in as my partner is currently unemployed! Still awful service and I am surprised that Ecotricity and other energy suppliers are still using them.
We have contacted Ecotricity and that have been somewhat helpful but can't offer us a different installer which is the only thing that seems like it would actually solve the problem.
Note to anyone else who's experiencing this - Ecotricity told us we're entitled to £40 compensation per missed appointment and we've so far recieved for one lot of this. Do badger your energy companies for compensation!!

I can’t give a 0 star but I would .
The only service I got was a text the night before to cancel an appointment that was made weeks before.
I got numerous emails and texts the weeks before telling me what I had to for their visit, unfortunately I can’t get the engineer out of his bed for them !

Don’t waste your time with them , use another energy supplier, going to move my business to Octopus and try again .

Horrific company. Turned up to fit a smart meter after I’d been bullied by my energy company into getting one. Waited in all day for them to turn up at 4pm and tell me they wouldn’t have time to fit one of the meters. The engineer went to the electricity meter and advised she couldn’t fit the smart meter because the fuse box was mounted on the wall and she isn’t allowed to climb a ladder (nor do they carry them). No apologies for the inconvenience at all. I’m a single parent who works from home and had to juggle my entire day to accommodate them.

Phoned Calisen to complain and was told it was my fault for booking the appointment online, as they ask about access if the appointment is booked over the telephone. How about they incorporate those questions into their online system? It’s not 1925.

I was then told that ladders would be delivered separately and I’d have to guarantee I could keep them safe and secure. Er, that’s not my job. I don’t have a secure place to store ladders, I live in a tiny terraced house.

Rude, incompetent staff. A joke of a company.

swapped my shifts to be off work today, slot for my appointment was 9am-1pm, waited in, no update. Contacted Calisen at 1pm and they said they haven’t got anyone booked to come to me, but will let me know as soon as possible. At half 2 they texted saying no one can come today. What a waste of swapping my shifts. Stayed in on my day off just waiting around for no reason.
