Probably depends on hope you amassed the the credit. If you've overpaid by €350 it's yours and you'll get it repaid. If it's some bonus credit it's probably forfeit.
If I switch provider and they give €100 bonus credit for changing I doubt very much they'll pay that it in cash if I subsequently transfer to another provider. Otherwise I'd be in a perpetual state of switching! If you're right I've missed a trick.I don't believe it's forfeit.
All credit on the account must be given.
I can't see them paying out bonus credit at any stage either in or out of contract.
They're obliged to pay you whatever you are in credit.
Switching Bonus is an energy credit and can only be used to offset charges on your Electric Ireland account. NO CASH ALTERNATIVES OR REFUNDS will be offered.
I live on my own. That's the balance of the government subsidy that I have yet to use. I am quite certain it dies if I decide to move suppliers when my present gas / electric contract comes to an end in 4 weeks.Why are you in credit by so much ? If it's because they try and even it out for you, I find they usually err on their side to get you to be wary of moving. There's a lesson here.
A supplier can apply the credit to your closing bill or credit you back through the same method pay your bills.
Thank you for going to that trouble
