Insuring italian reg car to take the UK

You cannot insure a Foreign registered car in the UK; end of. So you can insure your Italian registered car for use in the EU, but check with your Insurance company if your the equivalent of Fully Comp. as this only normally applies for upto 90 days. Your car will however be insured '3rd Party'  which is the EU requirement.

Try italsure They might be able to help, I have just insured my car for less than a quarter of the cost they charge here in Italy.

i only drive italian reg.cars and insure them here, automatically you will receive the green card valid for expatriation which you should sign but i can't remember how long it is valid outside italy but your local insurer would be able to tell you.
