In order to work at sea, you must have an appropriate seafarer medical fitness certificate. This is because medical conditions that are easily treated on land can be much more difficult to manage at sea, where qualified help can be days away. A seafarer medical certificate confirms you are fit to perform your duties at sea.

You need an ENG 1 certificate if you’re any of the following:​

  • a seafarer

  • in charge of a ship

  • serving on a merchant ship or yacht

If you remain unsure about which type of seafarer medical you need, further information can be found on the Maritime and Coastguard Agency (MCA) website here.

If you are concerned about a medical condition and how it might affect your chance of obtaining the ENG 1 certificate, please consult the Merchant Shipping Notice (MSN) document 1886 here. This is a comprehensive guide to how various medical issues are dealt with.

Before you attend, you will be asked to fill in a medical questionnaire. A link to this will be emailed to you when you book an appointment. Please ensure this is completed prior to your medical.

Please read the FAQ section below to ensure you are fully prepared before your appointment. If you have any further questions, please contact me.

  • This is my first (preliminary) HSE medical - what do I need to do?
    Before booking the medical, please read the following HSE guidance document: The Medical Examination and Assessment of Divers (MA1) This document includes important information on: medical issues that might disqualify a candidate automatically Body Mass Index (BMI), waist circumference and exercise capacity cutoff points There is also a questionnaire that your GP needs to countersign, which can be downloaded from this link: HSE Fact Sheet and Medical Questionnaire. Please note that without the completed medical questionnaire, we cannot issue a candidate with the HSE medical paperwork. ​ Please ensure you bring along: the completed GP questionnaire photographic ID, eg. passport or driving licence suitable clothing and footwear in which to complete a step-based exercise test
  • This is an annual (repeat) HSE medical - what do I need to do?
    Please ensure you bring along: a complete copy of your most recent HSE medical photographic ID, eg. passport or driving licence suitable clothing and footwear in which to complete a step-based exercise test
  • How long does the HSE medical take?
    Usually no more than 45 minutes.
  • When will I know the result of the medical?
    As long as there are no medical issues that require further specialist assessment, the decision is made immediately. If you pass, you will be issued with a certificate of medical fitness to dive which you can take with you. If you fail, or are found fit to dive only with restrictions, you will be informed of the reason(s). You have the right to appeal to HSE within 28 days for a review of the decision. Details of the appeals procedure can be found on the HSE website, here.
  • How long is the HSE medical valid for?
    The duration of the medical is 12 months. If a diver attends less than a month before their current medical expires, then the new medical can begin when the current one runs out. This mirrors the MOT system for cars in the UK and ensures that there is a "grace period" so that divers do not lose any days they have paid for.
  • What is the Chester Step Test?
    The Chester Step Test is a simple but reliable way to assess aerobic fitness. It is widely used in different occupational settings as it is safe, practical, quick and has reasonable validity. The test requires the candidate to step on to and off a raised platform or step (usually 25-30 cm in height), in time to a beat. Heart rate is monitored throughout, via a chest or arm strap, and the stepping rate is increased every 2 minutes. The test finishes when a heart rate of 80% of your predicted maximum is reached, or 5 stepping periods have been completed. The maximum duration of the test is therefore 10 minutes. As the test is dependent on measuring heart rate, please do not drink excess alcohol or caffeine in the 24 hour period before taking the test, as this could affect the results.
