VLAIO Ecologiepremie+ Application Guide 2026

The Ecologiepremie+ (Ecology Premium Plus) is a VLAIO grant for Flemish companies that invest in technologies and processes that are better for the environment. It is one of the most important sustainability-focused business grants available in Flanders.

The grant covers investments in energy-efficient equipment, renewable energy installations, waste reduction technology, water-saving systems, and other environmentally beneficial technologies. The technology must appear on VLAIO's approved technology list (the limitatieve technologieënlijst).

Grant percentages range from 15% to 30% of the eligible investment amount, depending on company size and the environmental classification of the technology. Small enterprises receive the highest percentages, while medium-sized companies receive slightly lower rates.

The Ecologiepremie+ is part of Flanders' broader strategy to support green economic transition. It complements other sustainability grants in Belgium and can be a significant source of co-financing for companies with environmental investment plans.

The Ecologiepremie+ is available to small and medium-sized enterprises (SMEs) with an operational establishment in Flanders. The company must be registered in the Crossroads Bank for Enterprises (KBO) and have a valid NACE code.

Large companies are generally excluded, though some exceptions exist for specific high-impact environmental technologies. The SME definition follows the European Commission standard: fewer than 250 employees, and either turnover under €50 million or balance sheet total under €43 million.

The investment must be in a technology on VLAIO's approved list. This list is updated periodically and contains hundreds of specific technologies categorised by environmental impact. Each technology has its own grant percentage and conditions.

Companies that have already started the investment before submitting the application are not eligible. The application must be submitted before any binding commitments (orders, contracts) are made — this is a strict requirement that disqualifies many applicants.

The grant percentage depends on two factors: your company size and the environmental classification of the technology. Technologies are classified from "A" (highest environmental impact) to "C" (lower but still significant impact).

Small enterprises can receive up to 30% for A-classified technologies, 20% for B-classified, and 15% for C-classified. Medium-sized enterprises receive 20%, 15%, and 10% respectively. These percentages apply to the eligible investment amount, which excludes VAT and certain non-qualifying costs.

There is a minimum investment threshold (typically €3,000 per technology) and a maximum grant amount per application. The maximum varies by program year but is generally in the range of €1 million to €2 million in grant value.

The grant is paid after the investment is realised and verified. You typically receive the payment within 2 to 4 months after submitting proof of completion. For larger investments, partial payments during the investment phase may be possible.

Step 1: Check the VLAIO technology list to confirm your planned investment qualifies. Each technology has specific requirements, grant percentages, and conditions. If your technology is not on the list, you cannot apply.

Step 2: Submit your application through the VLAIO online portal before making any binding commitments (orders, contracts, down payments). This is critical — starting the investment before applying will disqualify you.

Step 3: VLAIO reviews your application, typically within 4 to 8 weeks. They verify your SME status, the technology classification, and the investment details. You may be asked for additional documentation during this phase.

Step 4: Once approved, you proceed with the investment. You have a defined period (usually 12 to 18 months) to complete the investment and submit proof of realisation.

Step 5: After the investment is completed, submit the final invoices and proof of payment to VLAIO. They verify the investment matches the application, and the grant is paid within 2 to 4 months. Use Lucas to check your eligibility before starting.

The single most important rule: apply before you commit. No orders, no contracts, no down payments before your application is submitted. VLAIO enforces this strictly and there are no exceptions.

Check whether your technology qualifies for the highest classification (A). Sometimes a slightly different specification or model of the same technology type qualifies for a higher percentage. The technology list is detailed — read it carefully.

Combine the Ecologiepremie+ with other support programs where allowed. Some technologies may also qualify for federal tax incentives (increased investment deduction for energy-saving investments) or other regional programs. The VLAIO grants overview lists all combinable programs.

Keep your documentation clean from the start. VLAIO requires detailed invoices, proof of payment, and technical specifications that match the application. Discrepancies between the application and the actual investment are the most common reason for grant reductions.

Finally, plan your investment timeline carefully. The completion deadline is strict — if you cannot finish within the allowed period, the grant may be revoked. Factor in supply chain delays and installation timelines when planning.
