Xcel Energy Insulation Rebates Denver Golden CO
Note: Recently Xcel Energy’s website has had outdated information, which said rebates were expiring at the end of 2025. This is incorrect. All Xcel Energy insulation rebates are in full effect as of January 2026. The very significant bonus rebates may expire soon, possibly between April and June 2026, though this is an estimate.
Xcel Energy’s bonus insulation and air sealing rebates are for homes heated primarily with Xcel Energy’s natural gas. Homes heated with Xcel Energy’s electricity are not eligible for bonus rebates. Homes heated primarily with propane or fuel provided by other utilities are not eligible for Xcel Energy rebates. Improvements must be done by an Xcel Energy partner contractor like us to earn the rebates. The following rebate amounts are for homes heated with Xcel Energy’s gas service.
There are two rebate programs through Xcel Energy through which we can apply for rebates. We file the rebate paperwork for you.
Xcel Energy Whole Home Efficiency Rebate Program
Whole Home Efficiency requires requires starting with an energy audit, which we can do for you. You can earn up to 75% of the project cost with certain limits. Popular improvements include air sealing, attic insulation, and wall insulation. On completion of 3 or more improvements, you can get another 25% bonus rebate. Installing a heat pump in the WHE program, improving air leakage by 20%, and insulating the attic can earn you another $600 bonus rebate, but the insulation and air sealing must be done before installing the heat pump. Calculating rebates is complex. We will provide you with estimated rebate amounts as part of preparing your home improvement proposal.
Xcel Energy “Insulation and Air Sealing” Rebate Program
Xcel Energy Air Sealing Rebates
Up to $1000 for Xcel gas heated homes.
Xcel Energy Attic Insulation Rebates
Up to $1,250 for Xcel gas heated homes. Insulation level must be R 24 or less before upgrading, and must be upgraded to R 60. Air leakage must be reduced. Note: the R 24 limit does not apply in the Whole Home Efficiency program.
Xcel Energy Wall Insulation Rebates
Up to $875 for Xcel gas heated homes. Walls must not have any insulation before upgrading. Air leakage must be reduced.
Air Leakage Reduction Expectations
It’s not possible to estimate air leakage improvement amounts precisely. Sealing the attic may reduce 20%+ leakage if significant air loss comes from the attic. Homes with vented crawl spaces or inaccessible ceilings may have different outcomes.
Rebate Application Process
We file the rebate on your behalf. Air leakage tests are done before and after the project if applicable. You can choose between check, bill credit, or automatic deposit. Rebates typically process in 6-8 weeks.
Rebates apply only to single-family homes or multifamily units with up to four units per building. Buildings with five or more units do not qualify.
