Who is this course for?

If you are looking to do any underwater work in the UK and be paid, you will require a HSE qualification. The HSE Professional SCUBA course is the minimum requirement if you wish to work on scientific, archaeological or media diving projects.

The professional qualification is different to a recreational qualification. You will learn about equipment and procedures that are not taught in the recreational environment to this level, including full face masks (AGA), communication systems, lifeline signals and decompression procedures.

Please note: Here at DNQY we do not teach HSE diving, these are prerequisites needed to be able to enrol in a HSE Diving course.
