Keystone Energy Efficiency Program (KEEP) Home Energy Loan
Administered by National Energy Improvement Fund
KEEP offers low-interest financing ($2,500–$25,000, depending on credit score) for energy efficiency upgrades like heat pumps, furnaces, windows, insulation, and smart thermostats on Pennsylvania owner-occupied homes up to four units. Current rates (through September 30, 2025) range from 4.99% for 36 months to 7.99% for 120 months, with repayment flexibility up to 10 years. To apply, you must work with a NEIF-approved contractor and meet credit requirements based on your score.
KEEP-approved contractors can offer customers below-market financing for qualifying energy efficiency projects, expanding your addressable market for upgrades like heat pumps, boilers, windows, and insulation. You must be pre-approved by NEIF, certify that primary improvements are listed on Energy Star's Energy Efficient Products List at time of installation, and meet program compliance requirements.
KEEP is administered by NEIF under contract with PEDA as part of Pennsylvania's Energy Accelerator Program green bank. The program finances qualifying residential energy upgrades through direct loans scaled by credit score (640+ FICO eligible at varying ceilings from $10,000 to $25,000), with repayment terms of 36–120 months and promotional rates effective July 1–September 30, 2025. Target borrowers are single-family and up-to-four-unit owner-occupants in Pennsylvania; work must be performed by pre-approved contractors and certified against Energy Star product lists.
