They'll catch up with you eventually. The fixed penalty for driving with no insurance is �200 + 6 penalty points. If the matter is heard before a court, the maximum fine is �5000 and 6 to 8 penalty points are placed on a licence. (There's also an option for the court to impose an immediate ban).
It's likely that both you and your father will be prosecuted because the offence of 'causing or permitting' someone to drive without insurance carries the same penalties as actually doing the driving.
If 6 points are placed on your licence, it means that you'll have to be extra careful for the first two years after passing your test. For most new drivers, getting 6 points on their licence (in the first two years) means that their licence will be revoked. So, for them, a single 3-point speeding offence wouldn't mean that they'd lose their licence. However, you'll already have 6 points on your licence (which remain 'active' for 3 years). Obviously, you won't lose your licence as soon as you pass your test, but any additional points will result in your licence being revoked automatically. So a single speeding offence would be enough for you to lose your licence.
Lastly, your insurance (when you get some) will be significantly higher. If your father is prosecuted, he can also expect an increase in his premium.
