I want to borrow a car of a friend in the UK on a regular, but only daily basis. I searched the internet for possible short term insurances. The car is registered in Germany, so it is even technically insured already. However in this case, for damages caused by myself it is not insured.

For all short term insurance companies I found I need a registration number of the car to apply. The car is not registered here (since only occasionally around).

Does anybody have an idea how I can borrow the car and being insured against self-caused damages? Is there maybe some platform somewhere the guy can register and I borrow over that portal, to circumvent the lack of insurances?
