Becoming a tanker driver

Hi as a newbie i’m looking to get in to a tanker driver role and was looking to find out a bit more info on what i need to do and what i can excpet from the job.

  1. How long do i need my hgv licence for and will i need to have had ADR for a certian time?
  2. What companies/agencies do I approach, i live in the west london area?
  3. What earning can I excpet? I have been told by an agency that they only get around £21kpa i thought about the £45kpa
  4. what refrences do i need?
  5. What hours will i be doing?

If anyone can think of any other things i should think about then please advise, positive or negative feed back will be taken on board.

DOES THIS HELP ?
