F-gas fines: what are the amounts? (ILT rates at a glance)

If you search for "F-gas fine amount" you quickly come across figures on forums and in news articles — but which amount is actually correct, and who determines that? This article sets out the figures, with source, and explains why there is no fixed statutory rate table.

The amounts reported by industry source STEK

STEK (Stichting Emissiepreventie Koudetechniek) reports two standard amounts for violations relating to F-gas certification, based on statements from the ILT (source: stek.nl, "ILT controleert F-gassen!" (opent in nieuw tabblad) and "ILT handhaving vooral voor ZZP'ers zonder BRL100-certificaat" (opent in nieuw tabblad)):

• Individuals (technicians without a valid [BRL 200 personal certificate](/kennisbank/brl-200-f-gassen-persoonscertificaat)): €1,500 per violation.
• Companies (without a valid [BRL 100/F-gas company certificate](/kennisbank/stek-overzicht-bedrijfscertificaat)): €3,000 per violation.

STEK explicitly states that a company or technician can receive a fine multiple times if work is repeatedly carried out without a valid certificate — so it is not a one-off ceiling per company, but an amount per established violation.

Important note: these are figures as reported by STEK, an industry implementation organisation that works closely with the ILT — not a formally published rate list that we ourselves found on ilent.nl. The ILT's own enforcement strategy page (opent in nieuw tabblad) does state which *instruments* are used (order subject to a penalty payment, order subject to administrative enforcement, official report, administrative penal order), but no fixed euro amounts — the inspector determines the "most appropriate intervention" per violation using an intervention matrix. See also our article on ILT enforcement instruments for the full explanation of that step-up model.

Check if in doubt: for an authentic, current amount for your specific situation, contact the ILT itself (greenhousegases@ilent.nl) or consult STEK — the standard amounts can be adjusted by the ILT and are not a statutorily fixed national maximum.

Why is there no EU-wide or statutorily fixed amount?

The underlying European F-gas Regulation (EU) 2024/573 requires Member States, in Article 31, to establish their own sanctions that are "effective, proportionate and dissuasive" — but the Regulation itself does not prescribe euro amounts. Each Member State fills this in nationally. In the Netherlands, enforcement runs via the Wet milieubeheer and, in the case of more serious or repeated violations, via the Wet op de economische delicten (WED). That explains why you won't find a ready-made fine table on ilent.nl: the amount depends on the instrument chosen (administrative fine, order subject to a penalty payment, penal order, or OM track) and the severity of the case.

To illustrate how wide that range can be: in the case of large-scale quota exceedance by producers/importers, the ILT applies amounts that are entirely separate from the amounts for individual installers — for example, in 2026 the ILT imposed a penalty payment of €66.76 per tonne of CO₂ equivalent placed on the market in excess of the quota, with a maximum of almost €20 million, on chemical group Chemours (source: ilent.nl, March 2026 (opent in nieuw tabblad)). That amount says nothing about installation practice, but it does show that "the ILT fine for F-gases" is not a fixed figure — the instrument and the amount differ per type of violation and per type of violator.

What does this mean specifically for your company?

• Per technician, not per company. If three technicians work without a valid BRL 200 certificate, the risk is in theory 3× the personal amount — not once.
• On top of the company risk. A company without a valid company certificate is exposed to the company amount, separate from any fines per technician.
• Repetition escalates. In the case of structural or intentional violation, the administrative fine is not the end station — the WED track then comes into view, with a wholly different (higher) sanction category. See ILT fines for F-gases: risks without a valid certificate for the explanation of that escalation path.
• The fine is usually not the biggest cost item. Reputational damage, loss of your STEK/Kiwa quality mark and liability towards the client often weigh more heavily in practice than the direct fine amount.

How do you prevent ever having to pay this amount?

Step 1 — Keep an up-to-date certificate overview. Per technician: certificate number, category, expiry date. Set reminders well before the expiry date, not on it — a re-examination takes time.

Step 2 — Block work orders when a certificate has expired. If a technician is no longer validly certified, no work order may be signed off in their name any more. In Koldwerk's users and roles module this is a hard block, not a reminder that can be ignored.

Step 3 — Check the company certificate separately from the personal certificates. A valid company certificate is a separate requirement, alongside the individual BRL 200 certificates of your technicians.

Step 4 — Keep evidence of compliance. Work orders, refrigerant balance and leak-check reports together form your defence in the event of an inspection. See the refrigerant module for a registration that adds up.
