Learner drivers are seen as a greater risk at the wheel, which means you’ll probably find that your premiums become more expensive.
If you’re an experienced driver, particularly one with a clean history and a decent no-claims discount, you should think carefully about adding a learner driver.
However, it’s normally not as expensive as adding a driver who’s recently passed their test. This is because there’s an assumption that a learner driver won’t be driving as often, and only under your supervision as a more experienced driver.
