From that day, the final plan must normally be issued within 20 weeks.
Inside those 20 weeks sits an earlier deadline: the local authority has 6 weeks to decide whether it will assess at all. So a family should hear something within 6 weeks, and hold a final plan by week 20.
The regulations allow exceptions in limited circumstances, but the 20 weeks is the rule, and it is widely breached in practice. That is exactly why the number is worth knowing: if your case has gone past a deadline, you can chase in writing, quote the timescale, and complain if it slips further.
