I'm under 25. Are there any restrictions I should be aware of?

Drivers under 25 are restricted to cars with an ABI Insurance Group 16 or lower and with a power output of 120 brake horse power (BHP) or less. Note: This does not apply to wheelchair-accessible vehicles. 

In addition, only one named driver under 21 is allowed on the insurance.

This is why it's important to consider, when choosing your car, if any of your named drivers will be aged under 25 during your lease, as this may affect the choice of cars available to you.
