That, of course, assumes that the rental company is actually interested in the number of points on your licence. From various posts on here, and from my own experience, they never seem to be bothered about it.
In practice, it's far more likely to be potential (and existing) employers who're interested in the number of points an applicant/employee has on their licence.
