Home Insulation Rebates

Existing homes can qualify for rebates on windows, doors and insulation

efficiencyPEI offers grants for the installation of insulation, air sealing improvements as well as ENERGY STAR® windows and doors. Upgrades to the shell of a house (known as a building envelope) protects it from the elements and can yield big savings on heating costs. Upgrades will also make your home more comfortable and environmentally friendly.

In addition to rebates, financing is available through the Government of Prince Edward Island to assist with the up-front costs of insulation upgrades.

Income qualified Islanders may be eligible for free home insulation. Visit the Free Home Insulation Program to check your eligibility. 

How do I apply?

If you are interested in financing for the up-front costs, learn more about the energy efficiency loan program.

To get a home insulation rebate, follow these steps:

  1. To qualify for the provincial government insulation rebate, you must have an energy audit conducted by one of our energy partners. Contact them directly to begin the process.
  2. After receiving your EnerGuide Rating System report, complete your upgrades and contact your audit provider for a follow-up inspection.
  3. Your audit provider will collect your paid receipts for the upgrades, along with proof of income* (if required) to efficiencyPEI on your behalf. 

* Proof of income is your original July GST Credit Notice showing your net family income, marital status and province of residence.

Why do I need a home energy assessment?

The Home Energy Assessment is a mandatory part of the program. It provides useful information about your home’s energy performance that will help you make informed, decisions when operating, renovating or purchasing a home. Choosing the right upgrades will save the most energy, and be the most effective at lowering your monthly costs.

The Home Energy Assessment is offered at a subsidized rate of $99 plus HST.

Where can I find a list of contractors that install insulation?

You can search the Network of Excellence for contractors that install insulation.. You can search for a contractor by name or by the service they provide or you can view a list of contractors by county, or by program, by selecting an option from the "County" and "Program" fields.

What are the rebate amounts?

Rebates may be different for different types of upgrades.

  • For example, a below grade wall upgrade for a 30’ x 40’ basement with 8’ high walls going from R0 to R12 would be: (30’ + 40’ + 30’ + 40’) x 8’ = 1120 sqft = 11.2 SQ
  • Then the rebate would be: 11.2 SQ x R12 x $12 = $1,612.80 total rebate.
