If your organisation employs anyone who works at sea, ENG1 compliance is not optional. It is a legal requirement that ensures your teams are medically fit for safety critical roles. Whether you manage cruise ship staff, marine engineers, commercial surveyors or fishing crews, understanding ENG1 obligations protects both your people and your organisation.
Your employees need an ENG1 if they serve on merchant vessels or yachts, work on fishing boats in certain circumstances, or are in charge of a ship. This applies equally to senior officers, deckhands, interior crew and researchers. For HR leaders this means the ENG1 becomes a key touchpoint in pre-employment screening, ongoing health surveillance and operational planning.
The process is fixed by the MCA. The maximum charge of £115 ensures transparency, but there may be additional costs where extra testing is needed. For example, a BMI above 35 may trigger a fitness assessment and some roles may require drug and alcohol screening. Certificates can be unrestricted for up to two years, though younger workers and those with certain medical conditions may have shorter validity. Ensuring your HR system records expiry dates is crucial for maintaining compliance.
Medical conditions are not automatic barriers, but they must be declared. Well controlled asthma, some forms of diabetes and many common medications can still be compatible with ENG1 certification provided the doctor is satisfied the condition does not compromise safety at sea. In some cases restricted certificates may be issued, allowing duties with limitations.
For HR teams this means planning is essential. Encourage your staff to bring GP or specialist letters where relevant and book ENG1 appointments early to ensure operational continuity. If a crew member cannot be certified temporarily, this early awareness protects your rota, your vessel operations and your legal standing.
By partnering with a responsive occupational health provider, you gain visibility, predictable scheduling and reliable compliance across your marine workforce. The ENG1 may be mandatory, but the experience and continuity behind it are where HR leadership makes the difference.
