This 92-year-old woman overpaid energy bills for a decade—don’t let this shocking mistake happen to you

Imagine opening your monthly bill, paying it without question, and later discovering that you’ve been overcharged hundreds—or even thousands—of extra dollars for years.

That’s exactly what happened to a 92-year-old woman who unknowingly paid far more than she should have.

Her experience reveals just how easy it is for small details to drain thousands of dollars over time.

And it’s a reminder that this could happen to anyone if we don’t look closely at our bills.


For more than 11 years, this sharp and independent senior paid her National Grid energy bills without a second thought.

Like many of us, she trusted the numbers on the page and assumed the company had it right. But behind the scenes, a small oversight was quietly draining her bank account.

The culprit? A confusing coding system and a missed notification. When she switched her home from oil to gas heating, she didn’t realize she needed to inform the utility company.

As a result, she was billed at a higher “gas appliance” rate (code 120) instead of the more affordable “space heating” rate (code 140). The difference may sound minor, but over a decade, it added up to a significant overpayment.

“I thought it was outrageous, the bill I got,” she told CBS News. “We just look at the sum and we will pay the bill.” Her son, Christopher, who lives in Texas, added, “My mother has kept every single bill.” It was only after a careful review and some family sleuthing that they discovered the error.

Lawmakers and consumer advocates are sounding the alarm that thousands of customers could be in the same boat—overpaying for years due to confusing rate codes, missed notifications, or simple misunderstandings.

State Senator Mario Mattera and Suffolk County legislator Robert Trotta are pushing for legislation to protect customers from these costly errors. “God knows how many other people are paying the wrong rate for their gas,” Trotta said.

And while National Grid says it proactively reviews accounts to ensure customers are on the right rate, the reality is that mistakes can slip through the cracks.

The company doesn’t have to refund overpayments due to incorrect rate codes, but in this case, they’re working with the family to find a fair solution.


If you’re like most people, you probably don’t spend your afternoons poring over utility rate codes. But a little vigilance can go a long way. Here’s how to make sure you’re not overpaying:

1. Know Your Rate Code​

Every utility bill has a rate code—usually a number or short phrase—that determines how much you pay per unit of energy. If you’ve made any changes to your home’s heating or appliances, double-check that your rate code matches your current setup.

2. Review Your Bills Regularly​

Don’t just look at the total. Scan for changes in rates, surcharges, or mysterious fees. If something looks off, call your utility company and ask for an explanation.

3. Keep Records​

Like our Long Island grandma, save your bills. Having a paper trail makes it easier to spot patterns, errors, or sudden increases.

4. Ask for a Rate Review​

Most utility companies will review your account if you request it. Ask them to confirm you’re on the most cost-effective rate for your usage and home setup.

5. Stay Informed About Policy Changes​

Utility rates and policies can change with little notice. Sign up for alerts or newsletters from your provider, and check in annually to see if you’re still on the best plan.

6. Get Help If You Need It​

If you’re unsure about your bill, reach out to a trusted family member, friend, or local senior advocacy group. Many communities offer free utility bill checkups for older adults.
