Calisen Reviews 107

One star is way too generous for this bunch ... was supposed to have a smart meter upgrade today between 10am / 2pm , engineer calls me at 8am wanting to come early ( Friday innit ) I said I wouldn't be there til 10 am as agreed, then just doesn't bother turning up at all , no phone call, no email , no apology .
Just totally cack all round .

The appointment was booked weeks in advance and a week before the appointment I got a call to go through all the things again that they had asked at the time of the appointment. I was told I would get a text the day of the appointment which was booked for 12-1pm on the 3rd July 25. I heard nothing and at 1:30 I sent an email to customer service after which I had a mail asking again for my address and post code. At 15:15pm I had a call to say they were stuck at a previous job and wouldn’t be able to make today’s appointment. They apparently have problems at the previous job which meant they could not contact me or their office. I hope that doesn’t mean that the previous appointment hasn’t been without power for over three hours. Looking at Trustpilot this is a common occurrence so I am not going to book another appointment. Even last week Calisen came to read the meter and two days later came again as they said the previous reading was lost. Sounds a great company. I had turned down another very important appointment to accommodate this meeting which annoys me immensely.

This is a truly awful company. I suggest Scottish Power move their business.
First appointment engineer came on the wrong day.
Second appointment engineer did not turn up.
Third appointment waited in all afternoon only for appointment to be cancelled at last minute. No explanation.
Fourth appointment: we shall see.

When all this is over I will be moving supplier from Scottish Power.

No names mentioned so you know its a real review . Cancel meter swaps at last minute . 2nd month of waiting then they simply ring or text you saying they won't be coming . They probably still charge scottishpower as if they've done some work. My meters are faulty but there is no rush to swap them while I'm overpaying , cancelled my dd now so they can beg me for it. Don't use scottishpower . No support cometh.

Been waiting weeks for my supplier to send an engineer to fix my smart meter. Scott B came to my property and identified a leak, fixed the leak and installed a new meter for me. He let me know given the age of my boiler that there would be issues in potentially relighting it. He did identify that my pressure was low and contacted Cadent. Cadent arrived and requested he stay to light my boiler. He did and relit my boiler and Cadent rectified the pressure. Scott is an invaluable asset to this company and really went above and beyond.

Was due to have a smart meter fitted between 12 and 4 pm, at 3:30 pm they called to say they aren't coming due to operational reasons. The person on the other end could not have been less interested or enthusiastic. Almost sounded like he was going to sleep. Also, really do not appreciate them calling and then asking for my personal information, and when I push back, they quote it is because of GDPR. The General Data Protection Regulation (GDPR) is a European Union law focused on data privacy and protection. It outlines rules for how organisations can collect, use, and manage personal data. So, not really the best reason. Shambles and rubbish to deal with.

Was due to have smart meter fitted in September 2024,calisen phoned me to say they will not come on that day, gave me a new date may 8th 2025, I made a call to them 2 days before hand, office told me they had no availability for my Area so would not be attending, so I am in limbo, this is shambles.

Two reasons for my rating:
1. Calisan arrived when they said they would and the engineer phoned 5 minutes before arrival.
2. The engineer, Joel, was quick clean and had a fantastic character with a huge broad grin. He was a very pleasant guy and a credit to your company.

Appointment booked for between 12pm and 4pm on 12-06-2025. Phoned at 2.30pm to say not coming, no appogy, no explanation, no compensation. Next appointment July! Wasted day. Spent all day emptying kitchen and hallway for easy installation access as requested. Then had to put it all back. I think Scottish Power should look elsewhere for a more reliable company.

Calisen delivering the contract on smart meters for scottish power. Communication between the 2 organisations is poor. I gave up 2 of my days to wait for engineers to attend to my electric smart meter and then the 2nd day for my gas smart meter, bearing in mind I had received an email to tell me these would be completed on the same day, but when the engineer arrived it was not on his job card. I managed to speak to an advisor from Calisen who i'm sure I woke up with my phone call and he was less than helpful, to be told that an engineer would have to return the next day and there was nothing else he could tell me, he had no manager to escalate it to, but gave me a complaints email that I may get a response to within 14 days! So i waited all day next day for an engineer (10-2) he arrived 13:30 to tell me that the system has been down all day and that he could not get a signal to my smart meter therefore would be unable to complete the job today and that an engineer would have to be rebooked.
I have added this to my original complaint but dont hold out much hope. Unbelievable that Scottish Power contract their masses of work out to this company who deliver such terrible service to their customers. I'm contemplating looking for a new energy company as they've been less than helpful too. 1 star I gave for the engineers, who were both very helpful and lovely lads, shame they have to work for these.

Poor service. Do not recommend. Nobody has arrived at the appointment day, they have mixed up address and attended wrong one keep saying that they were at mine. Provided me proof with street name and postcode way different than mine telling me that engineer was walking from the postcode they provided. Pure disgrace and joke.

Got told a year ago by Scottish Power that I’ll be getting a visit from them in the next 3 months, no date or time arranged which is completly disrespectful so am I supposed to just sit doormant for 3 months twiddling my thumbs ? Never heard of these in my life and then recently A YEAR LATER they had the audacity to knock at my home unannounced and unexpected, if you expect to gain access I suggest you book an appointment and learn to respect people’s time, I’m not answering the door to any unexpected stranger.

Waited for 3 hrs between 12-4 only to be called @ 3.15 that for unforeseen circumstances can’t attend. Extremely poor service ! With no appreciation for other people’s time and efforts !

Disgustingservice, time off work and loss of pay for them to cancel the appointment at 6.30 pm the day before, Scottish power should stop using them. I will be seeking compensation.

They have cancelled my appointment 4 times now. They are useless company. I have no choice but to use them as they are working with Scottish power. They ask for no details or description of where the electric meter is at the property. Mine will require two engineers to access it. I was told this after I booked a day off work and waited in for them. The engineer took pictures and notes, they have now told me there are no pictures and notes. It's painful dealing with this company, they have no respect for people's time and money.

After Scottish Power continuing to suggest i install a smart meter to improve their billing accuracy an appointment was booked for between 12-4pm with calisen to install elec and gas smart meters. I had confirmed the appointment the night before and again earlier on the day and was assured this was going ahead, i was then called at 3:10pm only to be told they had to cancel due to unseen circumstances. Thank you for waisting my time, Great service ...

Disgusting customer service.

Had an appointment booked 4 weeks in advance only for them to cancel at the last minute, Rebooked for 4 weeks later only for them to not even turn up, Got a phone call from them 3 days later apologising and then saying they couldn't even rebook an appointment, Astonishing customer service considering it was their fault on both occasions hence the apology, Strongly advise against dealing with this company,

I was booked in for a smart meter installation. My time slit was between 10-2. At 12.53 I received a call saying that due to unforeseen circumstances the engineer wouldn't be able to attend today.
I had to take time off work and wait around for them.
This is the second appointment that they have cancelled.

Really poor service
