In your early discussions with your print supplier you must carefully consider the number of ballot papers that will need to be printed to allow you to allocate a sufficient number of ballot papers to polling stations and issue postal ballot packs. This will also enable sufficient paper stocks to be procured.
You should base your print-run on 100% turnout of eligible electors. There are significant risks attached to printing ballot papers based on lower turnout levels. For example, if the CRO starts running out of ballot papers on polling day it will be more difficult at that stage to print additional ballot papers and send these to the affected polling stations in a timely manner.
If you decide for any reason not to print ballot papers based on 100% turnout of eligible electorate, you should carefully assess the risks.
As part of your risk assessment you should consider:
the particular context of these polls
any particular local circumstances
projected turnout – taking into account the potential for late engagement and interest in the election by which point scope for adjusting plans will be limited – as a minimum you should assume that the turnout will be not less than the turnout at the last equivalent polls
any local or national issues which may affect turnout
whether having a stock of additional ballot papers ready for rapid delivery to polling stations is preferable, in terms of the ability to respond to additional demand, and more cost effective than printing ballot papers on polling day
You should also take steps to ensure that additional ballot papers can be printed at short notice if required and decide how CROs should brief polling station staff should this situation occur
