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!
