Is Availability Required for Gas Service to be Open?

Gas service may be open due to the customer’s recent departure. So no availability is required. However, if gas service will be provided and the gas is turned off, the availability of someone over the age of 18 will be required. In particular, the attendant must obtain permission when opening the access of the gas meter and checking the gas appliances. Therefore, the person with the availability will need to allow these authorizations. You will also need to gain access to the basement where your meter is located. Therefore, customers who are tenants must obtain the basement key and access permission from the owner of the building. In this way, authorized persons will enter the basement and arrange the gas service.

Why Pay Fees If You Pay By Credit Card?

National Grid institutions partner with Speedpayle in using credit and debit cards for payments. That’s why Speedpay charges some fees for payments. It typically charges $1.99 to cover the costs of credit card and electronic debit payments and $5.95 for non-residential payments. National Grid charges a convenience fee from its customers using this service. Because the best convenience in services is provided to the customer.
