    A deposit for Ameren Missouri residential service is usually not required - you will establish your credit with Ameren Missouri in your first year of service. A deposit may be required on residential accounts if you have a past due Ameren Missouri service bill, if your service is being reconnected after being discontinued for non-payment or you have four late payments in any 12 month period during the first 24 months of service.
    Ameren Missouri generally does not charge an activation fee for service. If you are a gas customer who chooses to use service on a seasonal basis, some fees may apply.
    <b>Gas Service</b>: The electricity must be turned on before Ameren Missouri can turn on your natural gas service.<br/><br/> <b>Electric Service</b>: In most cases, you do not have to do anything. For safety reasons, Ameren Missouri requests that you have your main breaker in the off position or your main fuse pulled prior to connection of service. Failure to do so may delay turning on service.
