Subsidies for Energy-Efficient Renovations in Slovenia: How to Save in 2025

Subsidies for Energy-Efficient Renovations in Slovenia. In 2025, Slovenia and the EU will continue their energy efficiency support programs, which help reduce the cost of home renovations. Let’s explore how they work and why such investments are worth considering.

The Eco Fund, financed by the national budget and EU funds (including the Green Deal), offers grants and preferential loans for energy efficiency improvements. In 2024, the fund distributed approximately €21.5 million in subsidies for solar systems and up to €5 million to combat energy poverty. The budget for 2025 has not yet been announced, but an increase is expected thanks to the EU’s REPowerEU funds. According to the Ministry of the Environment, Climate, and Energy, more than 19,000 grant applications have been submitted in 2024.

Why is this relevant?

Rising energy prices make renovations profitable. The average home in Slovenia consumes approximately 4,000–5,000 kilowatt-hours per year, costing €100–150 per month. Insulation, new windows, or heat pumps reduce costs by 20–30%, saving up to €400–600 per year. Energy-efficient Class A and B homes may be 5–10% more expensive at resale, but precise data for Slovenia is limited.

Starting in 2030, new buildings in the EU must be zero-emission under the EPBD directive, and renovation guidelines will be introduced for older buildings.

Subsidies for 2025

The Eco Fund offers (based on 2024, similar expected):

— Insulation of facades and roofs: up to €35 per square meter or up to €18,000 for energy-poor buildings.
— Heat pumps and solar panels: up to €1,500–€2,500, depending on the type.
— Windows and doors: up to €50 per square meter.
— Smart systems: up to €1,000–€2,000 for automation.

Applications are submitted online through eUprava; review takes 30–60 days. Work is performed by certified contractors.

Example

In 2024, a typical renovation (insulation + windows) for a 120-square-meter house cost €10,000–€15,000. The subsidy covered €2,000–€3,000, with energy savings of 20–25%.

Market Impact

The Slovenian real estate market grew by 7–8% in 2024. Short-term rental regulations from 2025 require limits (60–150 days per year), but not direct energy efficiency.
