General Payment Information for United Illuminating Users

According to the United Illuminating Company’s CEO, James P. Torgerson, the company has a service area of 335 square miles and is on track to energize Connecticut completely. Other subsidiaries of Avangrid focus on natural gas, electric, and related services.

All UI customers are free to choose who supplies their electricity. United Illuminating is a utility service distribution company that delivers electricity and maintains power lines.

If you don’t choose another electric supplier, you will be assigned United Illuminating’s default plan. The default plan is approved and regulated by the Public Utilities Commission but may have higher rates. The default rate is considered the Price to Compare, and you can use it to compare the rates and plans offered by other electric suppliers.

Here’s a complete list of the energy service suppliers and their rates.

  1. Budget Billing: You can opt for Budget Billing to pay the same amount each month throughout the year. It helps avoid seasonal fluctuations in bill amounts. Your average monthly bill depends on potential price changes, last year’s energy usage, and weather forecasts. You can learn more about Budget Billing here.
  2. Forgiveness Matching Payment Program: UI will match the payments you make to your outstanding, past-due electric bill if you qualify. You can learn more here.
  3. UI Matching Payment Plan: MaPP helps low-income customers maintain their electric service all year round by helping them reduce or eliminate past-due balances. You can learn more here.
  4. Payment Arrangements: If you’re having trouble paying your bill, you can apply for one of several payment arrangement plans offered by UI. You can call the customer service number to learn more.
  5. Payment Assistance: Low-income households can apply for payment assistance programs to help them pay their electric bill. You can apply for the COVID-19 Payment Program, Operation Fuel, the Connecticut Energy Assistance Program (CEAP), and the Winter Protection Program. You can learn more about each program here.

It’s best to opt for eBilling before you go for Budget Billing.
