There is no need to disclose medical history on your application. Instead we automatically exclude pre-existing medical conditions which you have:

received treatment or medication for (including diet) or
sought medical advice or
become aware of or might reasonably have become aware of any signs or symptoms during the five years immediately before the start of your cover. We may need to ask for additional medical information when you make a claim
Once you have been a member for two consecutive years, you may be able to claim for treatment of pre-existing conditions as long as you have had a period of two consecutive years with no treatment or symptoms for that condition since you became a member. Medical conditions that continue or keep recurring may never be claimed for since you will never have a two year symptom or treatment free period.

There are some conditions, namely diabetes, raised blood pressure, prostrate troubles and bowel trouble where certain specified related conditions will be excluded.
