What is the Housing Energy Efficiency Improvement Support Program?
The Housing Energy Efficiency Improvement Support Program operated by the government is a policy designed to achieve both heating cost reduction and carbon neutrality simultaneously. When residents of aging homes undertake improvement projects such as adding insulation, replacing windows, replacing boilers, or installing solar panels, the government covers a portion of the construction costs. In 2026, the budget has been expanded, broadening the scope of support, and the number of applicants is expected to increase significantly.
This is particularly an effective policy for households with heavy heating bills during winter. You can receive support for 50-80% of construction costs, providing substantial financial assistance.
Eligibility Requirements for Housing Energy Efficiency Improvement Subsidies
To receive subsidies, you must first check the eligibility requirements. Basically, you must meet the following conditions:
- Eligibility 1: Target Building - Residential properties (single-family homes, multi-family residences, apartments, etc.) completed more than 10 years ago
- Eligibility 2: Owner or Tenant - Both property owners and renters (monthly or jeonse) can apply (renter must obtain owner's consent)
- Eligibility 3: Income Standard - Generally no income restrictions, but some premium projects target households with income at or below 150% of the median income
- Eligibility 4: First-Come, First-Served Basis - Selection is made on a first-come, first-served basis within the annual budget, so timing is important
It's easy to overlook that renters (jeonse and monthly) can also apply. In this case, you only need the landlord's consent letter, so consult with your building owner first.
2026 Subsidy Amounts and Supported Projects
Energy efficiency improvement projects are divided into several grades depending on size and scope of work, with different subsidy amounts for each:
- Basic Type (Insulation Focus) - Maximum subsidy 5 million won | Window, insulation, entrance door replacement, etc.
- Intermediate Type (Heating and Hot Water Included) - Maximum subsidy 10 million won | Boiler and heat pump replacement, water heater improvement
- Premium Type (Renewable Energy Included) - Maximum subsidy 15 million won | Solar panel installation, Energy Management System (EMS) setup
The construction cost support rate is 50-80%, varying by project type. The basic type typically covers 50%, while premium types cover 60-80%. For example, if construction costs 8 million won, you would receive 4-6.4 million won in government support.
Application Procedures and Required Documents
The application process is simpler than you might think. You simply apply to the regional Energy Efficiency Improvement Project implementation agency (usually the local government or designated operator).
- Step 1: Confirm Application Agency - Visit your city or county office's environmental department or the dedicated Energy Efficiency Improvement Project agency
- Step 2: Consultation and On-Site Diagnosis - An official visits your building to diagnose energy efficiency and propose improvement solutions
- Step 3: Prepare Application Documents - Application form, building registry, energy diagnosis report, and landlord's consent letter (if you're a tenant)
- Step 4: Confirm Selection Results - Usually notified of selection within 2-4 weeks of application
- Step 5: Conduct Construction - Contract with the selected contractor and proceed with construction
- Step 6: Completion Inspection and Subsidy Payment - After construction completion, receive inspection and subsidy payment
Required documents generally include ID, building registry, and residence certificate as basics. If you're a tenant, you'll need the landlord's consent letter and a copy of your lease. The exact required documents can be confirmed by contacting the application agency.
Precautions and Tips When Applying
There are several things to keep in mind to effectively receive the subsidies:
- Timing is Critical - The budget is fixed annually and selection is first-come, first-served, so apply as soon as the notice is posted.
- Get Pre-Diagnosis - Most agencies offer free energy diagnosis. Requesting one in advance helps you develop an improvement plan.
- Confirm Approved Contractors - To receive government support, you must contract with designated contractors. Unauthorized construction will disqualify you from support.
- Tenant Must Obtain Landlord Consent - Since facility ownership remains with the landlord after construction, consult thoroughly in advance.
- Always Get Approval Before Construction - You must obtain agency approval before starting construction. Proceeding without approval will exclude you from the subsidy.
Expected Effects of Energy Efficiency Improvements
The benefits go beyond just government subsidies. Actual heating cost savings are significant, which is the greatest appeal of this program. Improving windows and insulation can reduce winter heating bills by 30-50%, while summer cooling costs are also reduced. Replacing your boiler with a high-efficiency model can save an additional 15-30%.
Additionally, it helps increase home value. Energy-efficient homes receive higher valuations in long-term resale. Installing solar panels can offset monthly electricity bills, further reducing household expenses.
