British Gas just increased my monthly DD from £67.50 to £112, despite the fact I am already in credit. I specifically set my DD to £67.50 when I took out the contract as I worked out how much energy I usually use based on the last couple of years and divided it by 12. This has worked out perfectly so far in terms of what I am paying and how much I am in credit by etc. Obviously now they don't let you reduce it back using the online service and its virtually impossible to speak to anyone at an energy firm at the moment.
they did this to me for a third time even though I am £400 in credit and have arranged to move away to octopus.
the first time I told them where to go as I was already building up credit in winter as I set my dd to cover my needs perfectly. Then they changed it again and said they couldn’t lower it as I was looking like I would go into a negative credit. So I got annoyed then.
Then 2 days after I said I’m moving they raised it again, crazy..
I get keeping customers accounts in a little bit of credit but £400 is 25% of my annual bill just as I’m about to leave..
