Utterly dreadful, amateur incompetance.
My wife took a day off work for the appointment, only for your engineer to turn up at Mom's with just an Electricity meter and NO Gas meter.
As she is Self Employed she will now have to lose another day's wages for you to come back and fit the Electricity meter you should have fitted at the same time.
The engineer knew he didn't have the right equipment, but didn't bother to call and re-arrange for a time when he had everything he needed instead of just messing us around.
You have also fitted a completely different meter to what we have, despite us both moving to Ecotricity at the same time.
At least this bloke didn't leave a mess like we were left to clean up when he did ours.
Incompetent, amateur, dreadful service, I wish I'd never agreed to have Smart meters.

Hi - thank you for taking the time to leave your feedback. We're sorry to hear about your experience and the inconvenience caused by the appointment not proceeding as expected. This is clearly not the level of service we aim to provide.
Please contact us at trustpilotqueries@calisen.com with your details so we can investigate further.
Very professional and excellent person…
Very professional and excellent person came to do the work and asked appropriate questions about our house and explained what he needed in order to do checks, etc.
So actual chaneover was carried our very well.
Main problem we had is that original date for work didn't happen but no-one told us, so we had to phone up to find out.
Also there was no contact to say the expected time of arrival, which would have helped us.
Otherwise Booking process was Ok

Mixed
Some good, some bad.
Good, the engineer kept to the date planned, there were several email reminders and a phone call when on route.
Bad, choice of dates was limited. Engineer had turned off our boiler and it wouldn't restart. This had been a problem in the past so not really his fault but there was no apology, he was hot and seemed irritable by that point. The home monitoring device was a new version so he couldn't explain how it would work (emails from ecotricity give details about a different device). The device still has no display so we don't know if it works. No explanation of what happens next.

Not a great impression
Turned up with a faulty electric metre and no gas metre (sold out). Arrived at 10:30am and finished at 3pm. Engineer did go and meet another engineer to get a replacement faulty part from their van and did book me in for a gas meter fitting.
Did not leave me with a smart monitor and have not received one since

The installation engineer was efficient and helpful answering a few questions. He left the meter area tidier than he found it.
I had to call customer service twice, once to rebook and a second time to provide a new telephone number. Both operators were friendly and unhurried.
