The Table Office puts together the Order Paper each day in time for the next meeting of the House. The deadline for any changes to the Order Paper (for example, amendments to motions or items for Remaining Orders) is the rise of the House on the previous sitting day. Where Westminster Hall sits later than the main Chamber, the deadline is the finish of Westminster Hall.
If there’s a recess approaching, any changes to the Order Paper for the first day back must be made by the time the House finishes sitting on the last day before recess.
