Just a heads-up for those due to join the Naval Service. It costs upwards of £7000 to process each applicant for entry into the Royal Navy and Royal Marines. In the six months since April we've wasted around half a million quid due to people arriving with pre-existing but undeclared medical conditions. The daft part about this is very often the medical conditions themselves may not be an outright bar to entry but they prevent the individual undergoing training from the "get-go" and result in discharge. If anyone arrives at HMS Raleigh or Lympstone CTC with an injury that affects their ability to undertake all elements of training, they will simply be sent home - this could also incur personal travelling costs. To rejoin after a medical discharge, it is not a straight-forward procedure and can add two or three months onto the joining process. This in itself puts you at the back of the queue, from scratch. Undeclared medical conditions require background checks and the New Entry Training Establishments do not have the infrastructure to undertake these checks, even it the individual is subsequently passed fit to re-enter. There is no option other than to discharge. The advice? Be honest & upfront before joining rather than risk an 18 year+ contract of employment. If you defer entry as an active candidate pending checks, you can immediately be re-allocated an entry date once found fit to enter. Training places pop-up at short notice due to last minute cancellations but once someone joins and gets discharged, the training place is wasted.
