The courts can be quite funny somtimes, I got a £100 fine with £50 costs plus 5 points (helpfully as it was within 2 years so kept my licence!) for doing 97 on a dual carriageway but as I was a student I put my income down as nil...and they made me pay the fine in £5 weekly installments 
With respect to the OP, that's pretty unlucky getting busted when just trying to help someone out, if it were me I'd describe how it happened and throw in the 'need the car for work' excuse and throw in that you help your dad out as well, isn't going to do any harm! Then hope they take pity on you and are lenient and give you 5 points (as in...we could have banned you but you're lucky..this time..) and a hefty fine but I don't really know how the courts view driving without insurance, even given the circumstances described. Good luck anyway!
