Changing energy supplier

[EvertonCJ]

It’s not knackered but it doesn’t clean or dry to a standard you would expect in 2018. Like talking to a wall though.
Just read my tenancy agreement and one of the conditions is I must speak to the agent/landlord if I want to change supplier.

Also on them comparison sights a lot of the suppliers seem to be unknown, small companies. Are these any good? And if I do manage to switch do I still have to ring up and tell my previous supplier I’m leaving or is it automatic when I get a new supplier?

I’m new to this so apologies if this is basic stuff to people.

My daughter is in rented accommodation in Reading. She was told that she could change energy supplier as long as she informed the letting agency.
I changed her supplier for her as she didn't have a clue and moved her to Avro. I've been with Avro for a few months as well and they have been fine.
My other daughter ended up with a massive electricity bill when she was in rented accommodation and I didn't want the same to happen to my youngest so I have been more proactive in helping with energy, broadband, etc.
