profit can no longer be sold as bs locks, as the new bs rating now exists, yet the old BS3621-1998 are still insurance approved for the immediate future.
so you have no issues in fitting these at present , some insurers only insist upon a BS3621 lock fitted, which can be the 1980 , 1998 or 2004 rating as all are bs locks.
Though they must carry the kitemark , you will find that newer profit and invincible no longer carry the kitemark so wouldnt carry a bs rating of any kind.
