The worst gas & electricity supplier we have ever dealt with in my entire lifetime. Moving into the property on the electricity account, we wanted to switch supplier and Opus did everything they possibly good to delay this and not grant the switch, despite being new tenants to the property. We had to restart the switch 3 times, which covered a period of a few months, just to leave the electricity account. For the gas account, they are charging £1.50 per day standing gas (we don't have a gas supply in use, so no units used) and we've asked them to remove the meter. We then had to pay a further £120 to get them to remove the meter (which we are still waiting for it to happen). Meanwhile whilst we wait for our paid appointment to remove the meter, which can take up to 10 months to arrange apparently, they will still continue to charge us £1.50 a day, they've got us over a barrel, absolute con artists milking us for hundreds of pounds and it's out of our control.
