Switching shouldn't cost anything, and any credits from your previous supplier should be returned to you within 14 days of your final bill.
If you're on a fixed-rate tariff, there might be an exit fee to pay if you leave before your fixed rate ends. Otherwise, switching should be free - but check with your current supplier if you're not sure. Any credits from your previous supplier should be returned to you within 14 days of your final bill.
Can I switch energy supplier if I rent?
Yes. Renters can generally switch energy suppliers, so long as they pay energy bills directly and are not paying them through a landlord. If you're unsure of whether you pay your bills directly or not, check your tenancy agreement or visit Citizens Advice.
