Renovating insulation

Upgrading insulation will help you save at least 10% of your home's energy cost and improve your home's comfort year 'round. When planning an insulation upgrade, you'll need to understand R-value, which is the measure of insulation's ability to slow the transfer of heat. Rebate amounts are calculated by the amount of R-value you're adding to your home.

"We probably should have done this first, as we noticed the biggest improvement in our electric bills when we did the insulation." George Meikle, Qualicum Beach, B.C.

Insulation upgrades require a PRC

Program Registered Contractors (PRCs) are trained by BC Hydro and FortisBC on installation best practices and on our rebates. They're committed to ensuring you achieve your energy efficiency goals. A recent survey showed that around 96% of our customers were highly satisfied with the services of their PRC.

Make sure your upgrade is eligible

Product eligibility

Insulation location Min. R-Value of new insulation
Attic – flat and cathedral ceiling R12

Installation requirements

  • Insulation must be installed in accordance with the Best Practice Guide Air Sealing and Insulation Retrofits for Single Family Homes.
  • Rebates are calculated based on the R-value of new insulation added. In cases where pre-existing insulation was removed (e.g. due to pest infestation or mold), the rebate is calculated on the difference in R-value between the new and pre-existing insulation.
  • Participants must resolve any pest infestations and rodent tunnels in the insulation prior to installation of new insulation. Presence of a pest infestation and/or rodent tunnels in the new insulation must be resolved to receive the rebate.
    • All insulation installed must be new, in good working order, not previously installed in another home or building.
  • All upgrades must be installed by a Program Registered Contractor.
  • Insulation upgrades made to a home that require installations to meet code compliance and new building construction requirements, including and not limited to renovations that require a “New Construction” or “Addition/Alteration” building permit, are not eligible.
  • A home defined as “substantially reconstructed” by the Homeowner Protection Act (as per Regulatory Bulletin) is not eligible. A substantially reconstructed home can include structural repairs, renovation where exterior walls and/or existing plumbing, electrical or gas lines are moved or it requires a New Home Registration Form under the Homeowner Protection Act.
