What a clean report does and does not mean
A clean check confirms that, at the moment of lookup, no UK insurer has filed a total-loss marker, no lender has registered an open agreement and no police force has reported the vehicle stolen. It does not confirm mechanical condition, repair quality, or work carried out in cash and never declared to an insurer. Treat the report as the legal and financial backstop to an in-person inspection, not a replacement for one.
