Distributor is not supplier
Everything above is your fixed network infrastructure — it cannot be switched and has no billing relationship with you. Your energy supplier is the separate, competitive company you actually pay, and you can switch it at any time using Ofgem's find my supplier guidance if you've lost track of who that is. On the gas side, registrations are held centrally by the Meter Point Administration Service — your supplier can look this up for you using your MPRN.
