Overpaying massively

I am sure there is a big problem as I am currently paying £599 per month and had message that I should increase my monthly payment to £934. My account is in credit by £3313. My house is a 4 bed detached and only myself and wife reside here as kids all left some years ago. My neighbour in same type and build of house pays £180 with OVO. My central heating and hob is gas but the electric cost is much higher than the gas. It seems stupid that I have let this go on for so long but having read over the last couple of years about soaring energy prices when I was told by Bulb a year or so ago that they don’t see a problem I put this to the back of my mind.

I’m in the same position but not in credit as much as you.
i cant seem to find an option to claim back the credit amount which is annoying.

Hey @mdvayani and @raceingmad, thanks for posting on community. Sorry for the late reply, we have been really busy and suspended community for a couple of weeks.

I’d be happy to take a look into your accounts and send over an email. Just let me know if you’re happy for me to do so. We can absolutely issue a refund as long as we have up-to-date meter readings and have been billing the account correctly. We’d just need to leave one month’s payment in the account.

@raceingmad it sounds like we may have incorrect estimates for your yearly usage, so our system thinks the payments need to increase. This sometimes happens if there’s a mistake on the national database, as they could give us wrong numbers which affect our calculations.

Thanks for getting back to me - I am happy for you to email me.
Regards
Phillip
