He is right on the above insurance info-they will only put you back into your original condition less deductible, otherwise it is called "Betterment" and you would be required to pick up the difference. I used to be a claims adjuster, and I have been in law enforcement for over 13 years. I am almost certain it works the same in the UK as it does in the USA.

Sorry to hear it my friend. People who do this kind of damage are weak and stupid. Has happened to me as well on previous vehicles.
