Hello. I am a solicitor with over 15 years experience I will try to help you with this.
I don't think that there is much you can do about this. The insurance companies will look at the actuarial tables and set their premiums accordingly. You could possibly bring a small claim against the other driver. Follow this link to see how https://www.gov.uk/make-court-claim-for-money/overview but there is a risk that this could lead to a further inccrease in premiums if he refers it to his insurers or if you declare to your insureres tat you have brougth a claim arising out of a motor accicent or if they find out in other ways. Maybe the best thing to do is to write a letter threatening action and demanding the money from the other driver but to view the letter as a bluff which may or may not work.
