Will claiming for injury against my boyfriend's insurance push his premium up?

I had a crash in my boyfriend's car as a penger and the other driver who was at fault didn't stop. They swerved into our lane and we had to swerve to avoid them, but we didn't collide. We crashed into a parked car; the owner of which is now making a claim on my boyfriend's insurance. He said if I make a claim for injury on his insurance it will push his premium up, but there is a claim being made against him anyway, so will it make any difference to his premium?
