How many small things in a year do you claim for?You can swap to monthly at renewal, yes.
I don't personally see the value of the £250 excess. The only things I've ever had go wrong on an F10 have been small value items.
I figured 1 thing going wrong is unlikely, 2 things even more unlikely. If 1 thing goes wrong the excess I pay is the £250, but ive saved £150 on the premium cost. If I make 2 claims I guess that's different.
