National Grid
Security The form of security that we use is SSL (or Secure Sockets Layer). This is a method of hiding the information that a web browser and a web server send to each other. An SSL-enhanced browser uses encryption to scramble the data you send to a website into an unintelligible string of seemingly random characters. This is the industry standard for encrypting digital communications between any two points across a network.


Most browsers will warn you that you are entering or leaving a secure area by presenting a dialog box. However, most browsers give you the option of turning off the dialog box display.


When on a secure page, you will see the lock icon on the bottom of your Internet Explorer or Netscape web browser. Still other browsers have different ways of displaying this information.


Unsolicited and Scam Emails
You may be aware that numerous scams are in operation that are designed to get you to provide personal details, including details of your bank account or credit card, for fraud or ‘identity theft’ purposes.

Some of these scams may try to use the brand of a reputable business, such as National Grid, in order to appear legitimate. We treat these scams very seriously. If you are concerned about an unsolicited or unexpected email that appears to come from National Grid please let us know immediately by sending an email to cyberresponse@ngrid.com.

When and how we may contact you by email

In the course of our business we may contact you by email to advise about the services we offer or activities we need to undertake in your area. We are committed to respecting your privacy and to complying with applicable data protection and privacy laws.

We will never:

  • ask you to email us any personal information, such as payment/financial details or your address
  • ask you to tell us your password
  • send you programs to install on your computer.

Before disclosing any personal information online, make sure you know who you are dealing with and be suspicious of anyone who asks for your bank account or credit card details or asks for your password and do not click on any links or email attachments unless you are sure you can trust the sender.
