Subject to underwriting criteria, any family member can normally be added as a named driver to your campervan policy, as long as they hold the suitable UK driving license. However, various insurers will insist on an age restriction, so it is wise to check. When calculating premiums, the insurer will consider various factors including age and experience and will likely base their assumptions on the youngest or least experienced driver. It is a good idea to consider how often a named driver will drive the campervan and if it is absolutely necessary for the individual to be on it.
