You’re best to phone them and find out. I took out an annual policy with ALLCLEAR before my RT treatment started and answered all the questions honestly. When it came to treatment I answered the question that ‘Treatment was planned but not started yet’. That was fine. As my treatment is now finished, I phoned them yesterday and a very helpful lady guided me through updating my policy to say treatment(other than HT which doesn’t seem to count) was completed….within the last 12 months. No extra premium just a £15 admin fee(which is a ripoff but there you go😊)
I know this is different but the point is they are there to sell you a policy and so are very helpful. A lot of people seems to use insurewith and are happy. You could also just go online and follow the questions and see where it gets you. I did this on several occasions just to see how different conditions affected the premium.
just make sure you declare ALL your medical conditions. I got a copy of my records from my surgery just to ensure I didn’t miss anything out.
