There is no single European commercial-diving licence. As of 2026, would-be commercial divers in Europe choose between national schemes recognised directly by IMCA — the Dutch and Norwegian systems are the clearest examples — and schools that train to the IDSA (International Diving Schools Association) Level 3 Offshore Air Diver standard, which IMCA references as meeting its own minimum criteria for surface-supplied diver training. This guide checks a school in each of nine countries directly against its own course pages — what it teaches, which standard it certifies to, and what you need before you can enrol — plus two honest exceptions: France’s INPP no longer trains anyone, and Scotland’s Underwater Centre in Fort William does not currently run the closed-bell saturation course it is historically known for.
What “commercial diver training” actually means, and who recognises it
Commercial (or “professional”) diver training qualifies someone to work underwater for a living — construction, inspection, salvage, aquaculture and industrial work — as opposed to recreational diving. Two recognition layers matter. First, a small number of national schemes are recognised by IMCA (the International Marine Contractors Association) in their own right: the Dutch scheme (NDC-RI, examined by Hobéon-SKO) and the Norwegian scheme (regulated by Havindustritilsynet, formerly PSA) both sit on that list. Second, IDSA — an international association of diving schools — sets its own Level 1 to 4 training standard, and IMCA’s own guidance states that observing the current IDSA Level 3 (Offshore Air Diver) standard meets its minimum criteria for surface-supplied diver training. That is not automatically the same as a school itself being named on IMCA’s recognised-scheme list, so where we could not confirm direct IMCA recognition for a specific school, we say so rather than assume it. See our guide to IMCA vs HSE vs ADCI vs ADAS for how these systems relate more broadly.
Netherlands: BC-opleidingen
BC-opleidingen trains commercial divers at its own facility in Enkhuizen, on the Markermeer — including an outdoor dive pit 21 metres deep with a movable floor. Training runs through scope levels from A9 up to B50 (SCUBA through surface-supplied diving), with Hobéon-SKO examinations and NDC-RI registration as the qualifying step. The Dutch scheme is recognised by IMCA (see IMCA D088, its current register of recognised diver certification) and the B50 qualification appears on the UK HSE approved list. Courses can be followed in English, and the campus sits about an hour from Amsterdam Schiphol — see our guide on how to become a commercial diver in Europe for the full step-by-step route.
Norway: NYD
NYD (Norsk yrkesdykkerskole) runs a roughly 16-week course aimed at the Norwegian Class 1 certificate for surface-supplied air diving to 50 metres, issued under Havindustritilsynet’s regulations. Like the Dutch scheme, this Norwegian national scheme is itself recognised by IMCA, and graduates also receive an IDSA Level 3 certificate. Entry requirements are open to newcomers: minimum age 18, basic swimming ability and a professional-diver health certificate — no prior diving experience is required. Western Norway University of Applied Sciences (HVL) runs a separate, IDSA-affiliated diver-education programme in Norway; if you are comparing options, check both directly.
Denmark: Diving2000
Diving2000, based in Odense, runs a SCUBA Commercial Diver course to 30 metres that follows the IDSA Level 1 standard, with the Danish Maritime Authority administering the final exam and issuing the health certificate. Its own course page lists the programme as 25 weekdays (20 in-school days plus 5 of independent study), open to holders of a recreational Open Water certificate or equivalent, and priced at 48,999 DKK excluding VAT as of our August 2026 check — treat that figure as a snapshot rather than a guarantee, and confirm the current fee directly. A separate surface-supplied course to 30 metres is available for those who complete the SCUBA level first.
Italy: CEDIFOP
CEDIFOP, based at the port of Palermo, describes itself as Italy’s only IDSA Full Member school and holds IMCA membership in the diving division for Europe and Africa. Its programme runs through OTS (Operatore Tecnico Subacqueo, roughly the inshore diver level) up to a “TOP UP” offshore stage that follows IDSA, HSE and IMCA standards and includes a block in Norway covering wet-bell, hot-water-suit and closed-bell familiarisation. Some course-date listings on CEDIFOP’s own site appear dated, so confirm current intakes directly rather than relying on what is published.
France: ENS, and the gap INPP left behind
Ecole Nationale des Scaphandriers (ENS), based in Fréjus, is France’s state-authorised commercial diving school: it is the only French school issuing the government’s Certificat d’Aptitude à l’Hyperbarie alongside IMCA and IDSA recognition, training to a working depth of up to 50 metres across separate construction, scientific/aquaculture and hyperbaric-technician tracks. For nearly fifty years, INPP in Marseille was France’s other major national diving institute; it was placed into court-ordered liquidation on 18 June 2024 and no longer operates. ENS is now effectively the standing option in France for this route.
Sweden: YRGO
YRGO runs Sweden’s only commercial-diver qualification (Anläggningsdykare), a 1.5-year, state-funded vocational programme based in Svanesund on Orust, leading to certificates aligned with IDSA and EDTC (European Diving Technology Committee) standards for diving to 50 metres. No prior diving or construction background is required — it is built into the course — but instruction is in Swedish, and the programme is selective (24 places per intake, with entry weighted by grades and experience when oversubscribed).
Finland: Luksia
Luksia, based in Lohja, runs Finland’s vocational professional-diver qualification (sukellusalan ammattitutkinto), with separate tracks for work diving and research diving and IDSA affiliation for its international recognition. Training runs 3–9 months depending on the track and prior background, based mainly at the Ojamon quarry lake, and costs around €3,400 for EU/EEA residents. The course requires B2.1-level Finnish, which in practice limits it to Finnish-speaking candidates rather than international students.
Greece: Hellenic Commercial Diving Academy
The Hellenic Commercial Diving Academy (HE.CO.DI.A), based in Agios Konstantinos, describes itself as the only commercial diving school in Greece and the Balkans. It is an IDSA Full Member and issues IDSA Level 1 to 3 certificates (Commercial SCUBA Diver through Surface Supplied Offshore Air Diver), training in open water, low-visibility conditions, ports and aquaculture units at its own campus with diving stations, a training tank and student accommodation.
United Kingdom: a more fragmented picture than it used to be
The Underwater Centre in Fort William once ran a full commercial-diver programme — including closed-bell saturation training with a self-propelled hyperbaric lifeboat (SPHL) — before collapsing into administration in 2018. JFD (part of James Fisher) acquired the closed-bell diving system in 2019 with the stated aim of re-establishing that training. As of our August 2026 check, we found no current course listing, dated announcement or industry report confirming that closed-bell or general commercial-diver training has actually resumed at Fort William: the site’s own domain shows only old, unmaintained content, and recent trade coverage (Energy Voice, Offshore Technology) describes the Fort William facility mainly as a subsea trials and testing centre, reintroducing ROV — not diver — training. If you are weighing a UK route, check directly with JFD and against the current HSE list of approved diving qualifications rather than assuming Fort William’s historic offer still stands.
How to actually compare these programmes
Three questions cut through most of the noise. First, which certificate does the job you want actually ask for — a national scheme IMCA recognises directly (Netherlands, Norway), an IDSA-standard certificate, or an HSE-approved qualification for UK waters? Second, do you already need diving experience to enrol, or does the course start from zero — most of the schools above (BC-opleidingen, NYD, Diving2000, YRGO, Luksia) take complete beginners, while others assume some existing background. Third, what language is training delivered in: English is confirmed for BC-opleidingen, while Sweden’s and Finland’s state-funded programmes require the local language. None of these programmes is “the only” route in Europe — check the current requirements and dates directly with whichever school you are considering.
Frequently asked
Is there one European commercial diving certificate?
No. Training runs through national schemes — the Dutch and Norwegian schemes are recognised directly by IMCA — or through the IDSA (International Diving Schools Association) standard, which IMCA references as meeting its minimum criteria for surface-supplied diving. Which one matters depends on where, and for whom, you want to work.
Which commercial diving schools does IMCA recognise directly, rather than via a training standard?
IMCA maintains its own list of nationally recognised diver-certification schemes (IMCA D088). The Dutch scheme (NDC-RI) and the Norwegian scheme (regulated by Havindustritilsynet) are on it. Most of the other schools in this guide train to the IDSA Level 3 standard IMCA references as meeting its minimum criteria, which is a related but distinct form of recognition — check IMCA’s current register before assuming either way for a specific job.
Does INPP in France still train commercial divers?
No. INPP in Marseille, France’s long-standing national diving institute, was placed into court-ordered liquidation on 18 June 2024 and no longer operates. Ecole Nationale des Scaphandriers (ENS) in Fréjus is currently the standing government-authorised option in France.
Does The Underwater Centre in Fort William still offer closed-bell saturation training?
We could not confirm that it does, as of August 2026. JFD acquired the closed-bell system in 2019 aiming to re-establish training, but current trade reporting describes the Fort William site mainly as a subsea trials and ROV-testing facility, and its own website shows no current commercial-diver course listing. Check directly with JFD before assuming the historic programme is running again.
Do I need to already be a diver before I can train as a commercial diver?
Usually not. Most of the entry-level schools in this guide — BC-opleidingen, NYD, Diving2000, YRGO and Luksia — accept candidates with no prior diving experience and build it into the course. That is different from specialist add-ons such as underwater welding, which do require an existing diving qualification first.
Which of these schools teach in English?
BC-opleidingen in the Netherlands confirms English-taught courses for international students. Several others (NYD, CEDIFOP, ENS, Hellenic Commercial Diving Academy) serve international candidates in practice, but Sweden’s YRGO and Finland’s Luksia are state-funded programmes delivered in the local language. Always confirm the language of instruction directly before enrolling.
