Zelená Domácnostiam (Green Households Programme)

A Slovak state subsidy programme administered by SIEA that covers up to 50% of costs for installing renewable energy and heat-pump systems in residential homes.

What is the Zelená Domácnostiam programme?

Zelená Domácnostiam (Green Households) is Slovakia's principal national subsidy scheme for residential renewable energy and heat-pump systems, administered by SIEA (Slovak Innovation and Energy Agency). Launched in March 2024 and continuing until December 2029, the programme distributes over €107.7 million in vouchers to support the decarbonization of residential heating and electricity generation. It forms part of the broader Slovakia Programme, co-financed by the European Union through the European Regional Development Fund, and represents a strategic commitment to increase the share of renewable energy use in Slovak homes.

The scheme operates by issuing vouchers—partial-cost subsidies that households can claim after completing eligible installations. A related programme, Zelená Solidarita (Green Solidarity), provides enhanced support for low-income households, covering up to 90% of costs to address energy poverty. Both programmes target the same eligible technologies and rely on SIEA's procurement and reimbursement infrastructure.

Which technologies are eligible for support?

The programme covers five categories of renewable energy and heat-pump equipment:

TechnologyPurposeNotes
Photovoltaic (PV) panelsElectricity generationSupports self-consumption and grid connection models
Solar thermal collectorsDomestic hot water and heatingLiquid-based systems; supports air-source heat-pump integration
Heat pumpsHeating and coolingIncludes air-to-air, ground-source, and water-source types
Biomass boilersCentral heatingTypically pellet or chip-fueled; requires suitable stack/venting
Small wind turbinesElectricity generationAvailable only in standard Zelená Domácnostiam; not in low-income stream

All equipment must be installed by contractors certified and under contract with SIEA. Installation dates from October 30, 2023 onward are eligible; retroactive claims are possible for work completed before voucher issuance.

What percentage of costs does the programme cover?

Cost coverage depends on household income and installation type:

Programme StreamStandard CoverageEnhanced Coverage
Zelená Domácnostiam (all households)50% of eligible costs65% if household ceases solid-fuel heating or installs equipment in an air-quality management area
Zelená Solidarita (low-income households)90% of eligible costsApplies automatically; no further enhancement available

Vouchers are calculated on the cost of equipment and professional installation only; design documentation, inspections, and optional services are often ineligible. A cap may apply per equipment type—for example, heat pumps have historically been limited to approximately €3,400 per voucher. Current 2026 subsidy levels are under revision by SIEA to align with Slovakia Programme priorities, particularly to incentivize heat-source replacement (heating decarbonization) over electricity-generation technologies.

What is the current status and timeline for applications?

Voucher issuance was suspended in mid-2025 when available funds were reserved. SIEA announced that new vouchers would resume in the third quarter of 2026. Revised programme conditions were published in the second quarter of 2026, focusing on simplified administration, faster reimbursement processing, and a strategic shift toward decarbonizing heating systems. The programme will receive an additional €20 million in supplementary EU funding, bringing total available resources to approximately €28 million when combined with unused vouchers recycled from rejected applications.

During suspension, interested households can register and queue for applications on zelenadomacnostiam.sk. Authorized installers continue to accept clients, knowing that applications will be processed once the programme reopens. Households should monitor the official website for announcements of each new voucher-issuance round, as slots typically fill quickly.

How does application and reimbursement work?

The process involves three stages. First, you submit an electronic application via zelenadomacnostiam.sk, providing property documentation (ownership or co-ownership proof, land-registry extract), installation estimates from SIEA-contracted installers, and proof of residence. SIEA assesses your application within stated deadlines—typically 30–60 days—and either approves and issues a voucher or requests corrections.

Second, once you receive a voucher, you must complete installation within 90 calendar days. Only installers under SIEA contract are eligible; this restriction ensures quality and accountability. You cannot proceed with installation before formal voucher issuance, so advance cost management is essential.

Third, after installation is finished and inspected, you submit a reimbursement request with invoices, proof of payment, and technical documentation. SIEA verifies the claim and transfers the voucher amount to your bank account. Processing times vary; the 2026 programme revision aims to reduce delays to 30–45 days by automating routine checks and streamlining error correction.

How does Zelená Domácnostiam differ from Zelená Solidarita?

Although both programmes share infrastructure and timeline, Zelená Solidarita targets specifically low-income households at risk of energy poverty. To qualify, you must fall within income thresholds (which were increased in 2026 to reach approximately 27% more households than originally planned). Zelená Solidarita covers up to 90% of installation costs, compared to 50% for standard Zelená Domácnostiam, substantially reducing out-of-pocket expense for vulnerable households.

Equipment scope differs: Zelená Solidarita supports photovoltaic panels, solar thermal collectors, and biomass boilers but excludes heat pumps and wind turbines. This focus reflects the low-income programme's priority on durable, low-complexity technologies and energy bill reduction rather than grid export or advanced HVAC. Both programmes employ the same voucher, application, and reimbursement workflow, so administrative experience transfers between them.

Income verification is the primary gatekeeping mechanism for Zelená Solidarita. Applicants self-declare their status in the electronic form; SIEA may request documentation to confirm eligibility. If you do not qualify for Zelená Solidarita, you automatically fall under standard Zelená Domácnostiam if your application is approved.

What are common misconceptions about the programme?

A widespread misunderstanding is that vouchers cover 100% of installation costs; in reality, only Zelená Solidarita reaches 90%, and standard households contribute at least 50%. Another misconception is that any installer can participate—in fact, only SIEA-contracted professionals are permitted, and this list is published on the official website.

Many homeowners believe they can install equipment and then apply for retroactive support; while historical installations (from October 2023 onward) may be eligible, the application must be submitted within specific windows when SIEA announces new rounds, and approval is not guaranteed. Finally, some assume that renewable-energy battery-storage systems are covered; currently, energy storage is ineligible under Zelená Domácnostiam, though this may change in future revisions. Always verify current eligible technologies and caps on the official website before signing a contract with an installer.
