I wouldnt touch a policy that was £4k per condition, in case they were unlucky enough to develop a lifelong condition at a youngish age - thyroid, diabetes, CRF, heart problems, urinary issues, can all cost a lot to treat, and it doesn't matter if they are indoor only or nor, in fact, if they are obese, some of those are more likely. Another thing worth looking at is what the excess goes to when they hit 9, AXA seem to be the only people who dont put it up when tehy get older.
