I've never heard of the Commercial Diver Medical - do I really need this?

The commercial diving medical isn't just another hurdle to clear—it's a crucial safeguard for both divers and their colleagues. In the United Kingdom, anyone who dives for work falls under the Diving at Work Regulations 1997. These regulations mandate an annual Health and Safety Executive (HSE) diving medical for all commercial divers. This comprehensive check-up isn't merely a formality; it's designed to ensure that divers are physically and mentally fit to handle the unique challenges of underwater work. The stakes are high in this profession, and employers take no chances. Without a valid HSE medical certificate, you won't find work in the commercial diving sector, no matter your skills or experience. It's a non-negotiable ticket to your underwater career, protecting you, your team, and the integrity of the industry.

It's crucial to understand that the HSE commercial diver medical isn't just a UK-specific requirement. Even if you're planning to work abroad, this certification often holds significant weight internationally. Many offshore operations in other countries specifically request the HSE medical, recognizing its rigorous standards. UK-based companies that send divers overseas for tasks like underwater research also typically require this certification. However, it's worth noting that some countries have their own equivalent of the HSE commercial diver medical. If you have your sights set on a specific location or company, it's wise to reach out to them early in your career planning. Ask about their specific medical requirements well in advance. This proactive approach ensures you have ample time to prepare, undergo any necessary examinations, and meet all prerequisites. Remember, in the world of commercial diving, being well-informed and prepared can make all the difference in landing your dream job, whether it's in home waters or across the globe.


What's the most common reason for failing the HSE medical examination?

The most common stumbling block in the HSE medical examination is often not what people expect – it's fitness level, particularly cardiorespiratory fitness. This is assessed through the Chester Step Test, a crucial component of the medical evaluation.


Here's a breakdown of the fitness requirements:


1. VO2 max above 44: This is the gold standard, allowing you to qualify for all commercial diving roles, including the physically demanding offshore saturation diving. To put this in perspective, this level of fitness surpasses that required for UK firefighters!


2. VO2 max between 40-44: If you fall in this range, you can still work as a commercial diver, but in less physically intensive roles. For example, you could pursue a career as a diving instructor.


3. VO2 max below 40: Unfortunately, if your score falls below 40, you're considered not fit enough for commercial diving in the UK.


It's important to note that being slim doesn't necessarily equate to being fit. Many aspiring divers are caught off guard by this test, especially if they haven't been regularly engaging in cardiovascular exercise. The Chester Step Test demands good aerobic capacity, which is built through consistent cardio training. To avoid disappointment and increase your chances of passing, incorporate regular cardiovascular exercises into your routine well before your medical examination. Activities like running, cycling, swimming, or high-intensity interval training can help boost your VO2 max and prepare you for the rigors of commercial diving.



I'm worried about my fitness and I'm not sure if I'll pass the test....

It's natural to feel apprehensive about the fitness component of the commercial diver medical, especially if you're new to the field or haven't undergone such an assessment before. While some individuals who engage in regular cardiovascular exercise may feel confident about their fitness levels, others might be unsure.


We understand that the full commercial diver medical can be a significant financial investment. That's why we offer a cost-effective solution for those who are concerned about their fitness levels or are just starting their diving careers. We provide a shorter, more affordable appointment that focuses solely on the Chester Step Test (the fitness component of the medical).


This targeted assessment helps you avoid the unnecessary expense of a full medical if your fitness level isn't yet up to par. If your fitness level doesn't meet the required standards, we can provide advice on how to improve and prepare for a future assessment. This option is particularly valuable for those just embarking on their diving careers or who have never taken the Chester Step Test before.


By offering this preliminary fitness check, we aim to help you make informed decisions about your career path and avoid potential disappointment or unnecessary costs. It's a practical way to gauge your readiness for the full commercial diver medical and can serve as a motivational tool to improve your fitness if needed. If you pass the pre-assessment, you can proceed to booking the full medical with greater confidence.
