How long does the planning meeting and entire planning process take?

Your planning meeting will take about an hour and half but can take as long as three hours. After your meeting your planner will research your plan, and work out what changes need to be made for it to be reasonable and necessary, that means that your plan has to be fair and have things you need in it. This should take 2-8 weeks. Once your planner has approved your plan, you'll have a plan handover meeting where you'll talk about how your plan works.
