Potentially, yes. Insurers can consider genuine part-time motor traders, but the applicant normally needs to show that a real business exists and that the requested cover matches the activity.
The useful question is not simply how many hours are worked. An underwriter may look at the number of vehicles bought and sold, repair income, advertising, business records, storage, experience and where customer or stock vehicles are kept. Someone trading occasionally from home presents different issues from a weekend mechanic using rented workshop space.
What evidence helps?
Purchase and sale invoices, accounts, tax records, trade advertising, premises agreements and photographs of secure storage can help explain the operation. A clear forecast may be needed for a new venture, but it should be realistic.
What can cause difficulty?
Unclear separation between personal cars and stock, vehicles kept on public roads, undeclared repair work, very high-value vehicles or no evidence of trading can make the risk harder to place.
Two examples
A weekend dealer may need to explain how cars are sourced, prepared, advertised and handed over. A mobile technician may instead need to show appointment records, qualifications, tool security and the limited circumstances in which a customer vehicle is moved.
Insurers set their own eligibility and minimum-activity rules. Working around another job does not guarantee acceptance or prevent it; the decision turns on the documented venture and the wording offered.
