Another Avro 'victim' here. I renewed with Avro new fixed price 30th May 2021 as after using comparison sites they were still the best option of anything but new and unknown companies with no feedback history.
I used Moneysavingexpert's 'Cheap Energy Club' to find the best deal. I had initially used this tool when I moved to Avro in 2019.
My deal that started in May was already a £13 / month DD uplift then. I was at the time in credit so wasn't too happy to have this uplift.
Their website is no longer accessible (unsurprisingly I guess) so I cant find out how much credit I have exactly and will have to rely on ofgen / whosoever takes over my account to provide a truthful reflection of my credit. Do I trust them? Who knows, but whatever happens we are all (well mostly) going to get 'burned' (pun intentional) by this.
I used Avro's website to check my statements but never downloaded them - perhaps I should have done. Hmm hindsight!
I dread to think who will be taking over - I got rid of British Gas who were completely useless so hope it isn't them.
