Calisen Reviews 935

Had an 8am-12pm appointment so booked half day holiday. At 11am got a call saying engineer was not available to attend today. When I questioned the fact he had texted the previous day to confirm the appt they then said he was called to an emergency and there wasn't another engineer available in the area. Not impressed by this or other similar reviews. Will I have to waste another half day holiday for a no show.

Had smart meters fitted 27th March 2025 id sent my readings on 26th March everything was fine until I got my electricity bill 28th March to discover the engineer had sent the wrong readings from the old meter which caused scottish power to believe I was using over £40 a day in electricity. I'm now left with the hassle of trying to sort it out, it may well be an easy mistake to make but it's his job and shouldn't have happened

Had them cancel on me twice at the last minute to fit smart meters, after taking 2 half days off my work for them.
They then tried to re arrange another date, and I was told there were no more dates available in my area at the moment, and to go back to my supplier again.
Worst company - AVOID

Vile sub contractor for British Gas !
Engineer caused damage to my front garden expensive plants and new sprouted bulbs.
He also parked his car on the property while he attended the rest off the estates houses.
This company declined any damage and I even supplied the ring door bell footage, Cheryl needs re training ! Trespass civil notice served for any future visits on my property without me being present. ! Apparently the engineer is a skilled gardener and can see under soil to extent of damage he caused my lack off due care and attention, ! Avoid this company at all costs as it seems to be a running thing with damage on property from this adhoc company

Embarrassingly poor company! Like many other reviews I’ve had multiple cancelled appointments, waited in for a 2-6 appointment, phone call at 4 to cancel and next available appointment was a month later, roll on to today and exactly the same scenario. The call centre wanted to rearrange for a third time but I declined. I’m a self employed gas engineer and I’ve lost £400 taking these two afternoons off work for no reason. They’re clearly overloading the engineers and leaving no time for possible issues which in domestic properties is a guarantee you’ll encounter.

Do better. And Scottish power stop using this shambles of an outfit.

First of all I would like to thank Scott, the gas engineer in UK north London Edgware area HA8, who came early this morning to save us from the cold and fix the gas meter system. I am very grateful to him and wish him good luck.

Another smart meter repair no show - same thing happened six months ago and we waited AGES to reschedule. I waited in, and got a call at 14:02 saying he would come in half an hour. Then another call at five to 4 to say the repairman was not going to make it. Do they actually turn up for ANYONE?! It is really annoying. Now booked for a slot next week - I just looove making work arrangements to be around for no shows...

I had an appointment scheduled (at the Power companies request) for 10 Feb, they called an hour before the end of the slot and said that due to unforeseen circumstances they would not be able to attend. This was rescheduled to the 7th of March, when the same thing happened. This was then reschedule to the 14th of March when, - you guessed it - the same thing happened.

Each time I have to arrange to be at home for the day, and to potentially be without power for the appointment, so this is not trivial.

I do appreciate that things happen, but three times in a row is just extremely unprofessional.

I had a smart meter installation appointment arranged for today, timeslot between 8am and 12 noon. I arranged for my child to be taken to school and took time off work to be called at 1050 to be told that the appointment was cancelled no reason given. He asked if I wanted to reschedule I advised no as this was the second time this has happened and I would go back to UW. Unbelievable this happened for a second time however I should have known better.

Calisen Energy engineers posting TV licence letters now? Had an engineer in all the labeled work gear turn up and post a TV licence letter.

A Calisen representative has been caught on camera poking around my property. I’m not even with Calisen so I do not appreciate trespassing on my private property. If I see you again I shall call the police.

Joel is a credit to your company. Polite and friendly and got a long awaited job completed efficiently

Avoid This Company at All Costs

We had a brand-new boiler that had just been tested and certified safe, with all the paperwork to prove it. Despite this, their staff decided to cap our gas. When we presented the safety documents, the response was, "I don't care," along with a mix of, "I'm not trained to look at a boiler," and "I don't know what I'm doing."

This unprofessional behavior caused unnecessary stress and inconvenience. To make matters worse, the company refused to take responsibility for the damages or even apologize for their employee's actions.

If you value your time, money, and sanity, do not let them on your property.

I received a card saying you had tried to read my meter and as I am disabled contacted my supplier to say the I had a smart meter fitted and it must have stopped working , they then set up an appointment . then earlier this week I think the 20th there was a knock on my door and a man wanted to read my meter , I told him he was early and had an appointment for the 23rd he waited when I moved things so he could get to the meter and said he would be the same person ,he said not to worry and he would not be calling on the 23 was very pleasant .then today a knock at the door , same man , I politely said I thought you read the meter 2 days ago . he replied I should have cancelled the appointment for today , and insisted I remove things from the garage again so he could take a picture and went to wait in his car complaining the appointment was for a set time and I should have been ready , he was very rude. I said” do you want me to put in a complaint about you “ his replay “ do what you want “ and people in the street heard the shouting and asked me what was going on. He was very aggressive and threatening and his shouting was overheard by a friend we was visiting and in the kitchen and she was shocked by whet she overhears 2 rooms away

We are with Scottish power and had our smart meter replaced by Calisen.

The experience with the technician was horrific, with him being incredibly rude and unprofessional. Along with him making up a false issue with our boiler, which was completely made up but cost us £170.00 to get this looked at.

I reported our complaint to Calisen who made excuses that the technician did the right thing and made no apology to his poor behaviour.

We have contacted Scottish power and have banned Calisen from coming to our property.

I am extremely disappointed with the service provided by this company. My energy provider arranged an appointment with them well in advance, giving them five weeks' notice to address a smart meter repair. On the day of the scheduled appointment, I waited for the entire time slot, but no engineer showed up. I wasn’t informed that they were unable to attend, nor did I receive any follow-up or apology for the missed appointment.

When I called to inquire about the situation, I was told that someone would contact me the following week to reschedule the appointment. Unfortunately, that call never came, so I reached out again. This time, I was informed that I would need to go through my energy provider to make a new booking, despite the fact that they failed to complete the original request.

It’s frustrating that not only did this company fail to fulfill its obligation, but their lack of communication and unwillingness to resolve the issue has been incredibly disappointing. I would not recommend their services based on this experience.

Canny lad all work done in a friendly and efficient manner I'm very pleased with new smart meter

I want to thank Joel for the excellent service he provided while replacing my meter. He worked quickly and efficiently and even took the time to repair the meter cover. He also supplied me with a display screen to help us monitor our energy usage, But he didn’t just leave it at that he thoughtfully pointed out that the orange light on the display meant my little electric heater was consuming a considerable amount of energy. His attention to detail and willingness to explain things clearly was greatly appreciated.

time slot for smart meter 8am till 12pm .Calisen ring me at 11am to say they have no engineer.wft?

Not sure why Scottish Power are still using them based on the very poor reviews.

I had an appt booked in for today for 14.00-18.00, they text me to say the appt was ‘at risk’. I called them and they cancelled the appt.

They just don’t give a hoot about customers.

@Scottish Power - look after your customers and bin these cowboys.
