How to cancel National Grid by mail
Start with your account details
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details National Grid holds, so the request can be matched to your account.
Write your request
Ask National Grid to cancel the account, stop all further charges and confirm in writing. Postbye prepares the letter from our English template, with the subject line “Subject: Subscription termination – National Grid”.
Send it by certified mail
Use certified mail for the 11217 Brooklyn address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the delivery receipt
File the receipt with the letter. A National Grid charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel National Grid, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
