If I switch to you, will I incur an exit fee from my current supplier?
Your contract with your current supplier will have an end date, which means you're bound to this contract and any resulting exit fees if you try to switch to Yorkshire Energy while in your current agreement. It's always best to check with your current supplier before switching, as they will be able to advise you on your current contract and it's terms.
Ofgem, the industry regulator, say that if you have 49 days or less remaining on your current contract, you can switch supplier without penalty or exit fee charges. If you are within this window you will not be charged.
