It won’t be if you can’t buy insurance.
Might it not be easier to own the vehicle conventionally (ie. registered in your name) to at least start building some ‘No claims bonus’.
Most Motor insurance in the UK operates at the lowest level of mass demand. That is: Joe Soap, with a standard vehicle, registered to his home address. Some bods even struggle at this most basic of levels, but hey-ho. In other words, you (with your zero no claims bonus and a motorcycle - make / model / value unknown - registered to a company) do not fit into that tidy box.
You’ll very probably get nowhere online. This means you’ll probably need the services of a specialist broker, not a chimp in a call centre. Try:
Principal Insurance
Howden Insurance
Lexham
Heritage
Note; These names are perhaps most often associated with ‘Classic’ or ‘Special Build’ (ie. Nonstandard) vehicles. But, with luck, one or more of them might have enough imagination to help you.
