Final switch tips. When you make your final selection, don’t call your current electricity provider to cancel. Sign up with the new company only. Try to sign up at least five to seven days before your plan expires so the overlap between the two billing cycles is negligible. Some people switch too late and pay higher prices during the transition. If you have a smart meter, the state rule is you must be switched within 48 hours. But five to seven days is safer.
