Wizard,
premiums are based on your age, whether you smoke, how much you want coverage for and for how long. Therefore, although £18 works for me, your premium may be slightly different. However, I think the point to note is that any serviceman/woman of the same age applying for the same amount of cover, for the same period, will pay exactly the same premium. This is regardless of duties (i.e SF or Admin pay the same) and we are covered for all theatres and CBRN attacks. Hope this helps, as you may guess I am a convert!
Thanks Boot. I will be making the necessary enquiries today. Seems like a good deal to me (where's the catch?)
