Customer Service Reviews

National Grid has received a fair number of negative reviews on consumer advocacy websites such as the Better Business Bureau,, and That being said, given the large number of customers National Grid serves (3.3 million customers in Massachusetts, New York and Rhode Island), and that most people tend to leave comments about service only when they have a problem (and are unlikely to bother commenting online if they are happy with their service), this isn't particularly surprising.

The issues that unhappy customer have tended to complain about include high prices, billing mistakes, and unpleasant experiences with customer service. However, few customers have complained about the quality of natural gas service they receive from National Grid.

If you are unhappy with National Grid customer service, we suggest taking a look at customer reviews of alternate Energy Supply Companies (ESCOs) operating in New York. With New York Power to Choose, natural gas customers in the National Grid Service area have a choice of which company provides their natural gas supply. ESCOs offer a wide range of energy and price options, and many can offer superior customer service than large utility companies.
