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 .
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.
Scottish power are not serious about getting their customers on a Smart meter.Appointment booked for between 12pm and 4pm on 31-10-2025. SMS at 2:30pm to say not "Unfortunately- Blah Blah" , no appogy, no explanation, no compensation. Wasted day as I cancelled appointments. Whole day spent emptying kitchen and hallway for easy installation access as requested. Ended up putting all back. Not sure if my new appointment will be hounered. Fingers crossed
Terrible company. Trying to get my faulty electric meter fixed, I'm stuck paying whatever it last read before it broke. Initial wait of a couple months for engineer to visit start of September, they called last minute to say it wasn't happening. Rearranged end of October, likewise. Got a text new appointment date of 5th Jan 2026. I have no faith it'll happen then either.
Don't worry about the inconvenience of having smart meters fitted. Calisen deal with this efficiently and effectively by not attending your appointment in the first place! They don't even have the courtesy to tell you. I wish I'd Googled prior to emptying our stair cupboard in anticipation. Unfortunately you can't give zero stars. To think they have the balls to say they'd charge YOU £40 for inconveniencing them!
I echo everyone elses reviews... Repeatly booked appointments and no one turned up. My favourite was today when I had a cheery call from the fitter asking about parking and telling me he'd see me in 15 mins. 20 mins later a call from Callisen, saying that it had been cancelled. Impossibly hard to contact them. The fact that the tell you that if the customer cancels on short notice you will have to pay £40 is galling.
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.
Probably the worst firm we have experienced this year. Unreliable, appointments cancelled at last minute after we’ve waited in, the remade appointments a month ahead. It has taken 6 months and 5 visits and still no fully working smart meter. It seems Ecotricity only use Calisen so its a monopoly we can’t escape. Hopeless. On a positive note, the engineers that called were friendly, pleasant people.
The man texted to let me know he was 20 minutes away, arriving just over half way through the four hour time slot. He was very painstaking and put in a backing board for another bit of the equipment that lacked one. I live in Devon. Maybe problems people are experiencing are down to area.
