Have you contacted the utility companies for your new area (water, sewerage) to let them know you'll be a new customer?
With regard to gas and electric, you may be able to continue your existing arrangements in your new place. Make sure you read the meters when you leave your old place and when you get to your new, so you don' t pay someone else's bill.
Post redirection is very important as Mesquite says. There's always some person or organisation you forget, though making a list really helps anticipate problems.
Be able to make a cuppa when you reach your new place, too. You'll need it,.or your helpful friends will, or even your new neighbours.
Good luck
