ENG1 Medical

If you are looking to make a career at sea, The MLC (Maritime Labour Convention) states that every seafarer must have a valid medical certificate, also known as an ENG1. 

The medical proves that you don’t have any serious medical conditions that could prevent you from performing your duties on board.

Further information about ENG1 medicals can be found here: https://www.gov.uk/seafarer-medical-certificates

As part of the medical, you will need to provide a urine sample so that your kidney function and blood sugar levels can be tested. This is not a drugs test.


Photographic Identification – driving licence, passport or discharge book. 

Please avoid exposure to loud noise 16 hours prior to your medical, as this may impact your thorough hearing test. 

Wear comfortable clothes as a step test is sometimes needed as part of the medical. 

A dental certificate may be required. It is advisable to see your dentist at least annually. 

If you are a contact lens wearer, please wear your glasses on the day. 

Please bring any information regarding your medication, medical problems or hospital admissions since your last medical. 

The certificate is valid for two years. For medical reasons, it is possible the certificate may be issued for a shorter period of time. You can renew your certificate with us by making an appointment in advance. 

You will be asked to complete a questionnaire and provide a urine sample before seeing the nurse who will measure your height and weight, take your blood pressure, and test your hearing and vision. You will then see the doctor for a physical examination. Sometimes other tests are needed such as a step test, an ECG or spirometry (breathing test). If you have any previous medical history then the doctor will discuss this with you too. 

It is recommended to check with your employer what they require. Further information can be found at https://www.gov.uk/seafarer-medical-certificates
