Courtesy car ?

So I had a NONE fault accident and the 3rd party insurance company ( Churchill) gave me a courtesy vehicle from Thrifty as mine had got into repair,

Went shopping and someone has hit there door onto my front wing and left a tiny dent , my excess is £50 if there is any damage on the vehicle 

Just wondering once I’ve paid the £50 would I have to pay anything else & does my insurance No claim bonus’s or premiums get affected? 

Thanks
