the later you leave it the more expensive tickets will get

you could just buy a flexible return ticket which will allow you to get on any train from london to norwich and any train from norwich to london, so you can just get on the first one when you arrive. that would be ?51.70 all together, if it was at off-peak times (before 1630 leaving london) which I think your journeys are
