Hi, I have been a customer of Together Energy for over a year now and have just renewed with them. My monthly bill has gone to £48 from £60 pm.
I have to say the service I have had from Together Energy is amongst the best I have had from any utility provider or anything else for that matter. I cant say I have spent any longer than 1 min on hold.
I have an E10 meter with an Electric boiler powering a wet heating system. Together are by far the cheapest provider I have found.
