Fantastic engineer

Fantastic engineer, who told me about every step. Explained what was going on. Showed me how the in home monitor worked and set it up. Solid work and also had a chat about future expansions for when I might want Electric car charger as well as other things like fuse capacity that while not problematic, might be worth fixing when I get electric charger work done. All in all, was quick efficient and friendly. I would highly recommend Calisen. Kept to schedule and a re-plan for dates was done in advance and I was kept informed.

The installation went well enough

The installation went well enough, but then I was told that the installer didn't have the internal display, but I would receive it within a week. Nothing happened and it took several phone calls and a few weeks before I finally received the in house display.

Three Phase Smart Meter!

I’ve been waiting several years to get a three phase smart meter. Thanks to Ecotricity and Calisen Metering I now have one and it was all very easy for me.

The installation was great. Nice and easy, great guy installing it - however, despite ringing Ecotricity after a few weeks to remind them my readout panel still has not been activated.

Friendly Professional Service

The engineer (Edward), was very friendly, professional and thorough. He worked very tidily, cleared up any mess, and left things as he found them. Many thanks.

The technician who came to install our smart meter was on time, quick and efficient – and communication surrounding the installation was frequent and helpful. However, the meter that was installed was a new one that the technician was not familiar with, so he could not tell us how it worked, nor was there a manual that came with it. We were pretty much left to our own devices, and we still don't really know how to use the information the meter generates to our best interest.

Terrible service

Needed to arrange about four different appointments due to engjneers not having working devices, reporting faults that were not faults, missing appointments and not providing home display. Customer service gaslit me saying I rearranged an appointment when they couldn't make it. When I complained they just replied with my complaints with added inaccuracy. Didn't offer compensation. I needed to take five days off work and the whole process took over four months.

Engineer not properly trained

Engineer left with solar panels not working after he switched them back on. He also left solar I boost disconnected and lying in electric box. He didn’t know what it was for and thought it was ‘old kit that didn’t work anymore’.
He clearly didn’t know about solar systems. Company sent out another engineer 5days later to install the I boost . I sorted the solar panels myself.

Hi – thank you for your feedback. We’re really sorry to hear about your experience, particularly regarding the issues with your solar panels.

This isn’t the level of service we aim to provide, and we understand how frustrating it must have been to be left with your system not working correctly and needing a follow-up visit.

We’re glad following the second visit and with your efforts you're now back as expected, however if you need any further support with this issue please email us at trustpilotqueries@calisen.com with your name and address, and our team will be in touch.
