If you're a United Illuminating (UI) customer, you have thousands of dollars worth of savings available to you through rebates, discounts and special programs. Many of these savings are through Energize Connecticut, a statewide initiative dedicated to making homes and businesses in the state more energy efficient.

These rebates and programs span a variety of energy upgrades and services. Whether you're looking to save thousands on a new heating system, want discounts on efficient light bulbs or something in between, you're bound to find something that works for you.

United Illuminating (UI) Program Overview

UI Smart Solutions

UI Smart Solutions is a marketplace you can use to find discounts on energy products like light bulbs and smart thermostats. Here are some of the largest discounts at the time of this writing:

  • $100+ Off Select Smart Thermostats
  • 40% Off Select LED Light Bulbs

To capture these savings, all you need to do is go to and select the products you want to buy. When you check out, the site will verify that you're a UI customer and apply the discounts to your order.

Home Energy Solutions

Through UI’s Home Energy Solutions program, you can get a full home energy audit and improve the energy efficiency of your home for only $50. The average Connecticut household that participates in this program will receive $1,000 in services and around $200 in energy savings a year.

During a home energy audit, an energy technician comes to your home to make and recommend energy efficiency improvements. This includes

  • The installation of energy-efficient products, like LED light bulbs, low-flow showerheads and smart plugs.
  • Finding and sealing leaks in your ducts, doors and windows
  • Safety tests that test appliances and gas lines for combustion, carbon monoxide and leaks.

After these initial tests and improvements, your energy tech will suggest further recommendations to increase the energy efficiency of your home. They will also make you aware of any rebates and discounts available to you through Energize CT. For example, right now you may be able to get $1.70 off per square foot of insulation recommended by the energy tech.

On top of all that, you may be able to waive the $50 fee and qualify for special rebates if you fall under certain household income thresholds.

Water Heater Discounts
