Don't Switch Energy Supplier
Normally it's good to shop around for the best energy tariffs, but in the current market, it's best to stay with your current supplier for now. Even if you were with one of the energy companies which have gone out of business over the last few months, you shouldn't look to switch. If Ofgem have not assigned you a new energy supplier yet, they will do shortly, and you will not have any breaks in your gas and electric services.
Until you have been assigned a new energy provider, you should not make any changes yourself. Once you have a named provider, you are free to change to another supplier, but Uswitch, which helps anyone to find the best deal on energy suppliers is recommending that nobody switches just now.
