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 c... See more

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!

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... See more

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 !

I would give 0 if possible. Had to take an entire day off unpaid only for them to cancel before the appointment slot. Terrible customer service over the phone

Bunch of monkeys, was asked to contact them to get a new meter installed, was told someone would contact me to arrange a time, no one has, and now they don't answer their phone.

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.

Firstly you have next to no chance that they will pick up the phone when you try to contact them. I've wasted hours of my life listening to the same 2 minute music loop that I think I'm los... See more
