The CleanBC Better Homes and Home Renovation Rebate Program requires the following information to calculate your rebate:

  • The R-value of new insulation added
  • The square feet covered by new insulation

The R-value that you have added is multiplied by the square feet covered, and then by a specific dollar amount that differs for each area of your home, as indicated in the table below.

Location Installed Minimum R-Value Added Dollar amount for rebate calculation Maximum Rebate
Attic (flat and cathedral ceiling) R12 $0.02 $900
Exterior wall cavities R12 $0.09 $1200
Exterior wall sheathing R3.8 $0.09 $1200
Basement/crawlspace Walls R10 $0.09 $1200
Other (exposed floor, floor over crawlspace, basement header) R20 $0.07 $1000

Example: I had R20 of existing insulation in my attic and added R30 for a total of R50. I covered 900 square feet. My rebate is calculated as follows:

R30 × 900 sf x $0.02 = $540

My rebate for this work is $540.

Please note:

  • Rebates are calculated based on the R-value of new insulation added and not the total combined final R-value for new and pre-existing insulation.
  • The insulation added must have a minimum R-value added per location outlined in the table above.
  • A minimum rebate of $500 is required for each insulation location to be eligible for either for both the Two Upgrade Bonus and the Home Energy Improvement Bonus.
  • The insulation rebate amount cannot exceed the installed cost of the eligible upgrade indicated on the invoice.
  • You cannot access a rebate for both crawlspace wall and floor above crawlspace – you must choose one or the other.
