Switching Gas

Hello, I was under the impression I had switched all energy & gas, but have realised I have not switched my gas account. How do I go back and do this? Preferably as quickly as possible as the old gas company is more expensive!!

@Lydlz it looks like the national gas database for your postcode is quite messy! If you’re able to send us a picture of the gas meter to help@bulb.co.uk we’ll get the gas over to us as soon as possible.
