    Which products are eligible for rebates?

    • It's our goal to make upgrading your small business easy and affordable. That's why most of the products on National Grid Marketplace are eligible for rebates. Below each listed product, you'll see a tag and quick description of any available rebates.

    Is everyone eligible for a rebate?

    • To be eligible for rebates, you must be a National Grid small business customer.
    • Your instant rebate will be automatically applied at time of checkout. We will verify your eligibility prior to the checkout process.
    • National Grid small business customers are limited to 3 wi-fi thermostats, 10 lighting rebates, 4 water-saving and 6 APS rebates. You are eligible to purchase more products at the non-rebated price.

    • All product warranties are provided by the product manufacturer. Please visit the product manufacturer website for all warranty information. 



    • Some thermostats require a C-Wire to power the device, like the Honeywell thermostats and ecobee SmartSi thermostat offered on this store.
    • Nest Learning Thermostats do not need a C-Wire to function and the ecobee3 HomeKit-enabled thermostat comes with an adaptor for those without a C-Wire. 
    • If you do not have a C-Wire on your existing thermostat, there are products in the market that act as an adapter (type “thermostat c-wire adapter” into your favorite search engine), or a contractor can help you install the device. 
    • Make sure to check your current wiring before purchasing any thermostat, and consult the installation information shown above.
