Timing of the issuing of postal votes
Postal votes must be issued as soon as practicable after the deadline for the delivery of nomination papers.2
You should put arrangements in place to ensure that electors receive their postal ballot papers as soon as possible and prioritise any postal votes that may need to be sent overseas in order to maximise the time that postal voters have to receive, complete and return their postal vote.
The EMB may make directions or recommendations for when the first issue of postal votes should be dispatched.
Existing elector with existing postal voting arrangements
Once the deadline for withdrawals has passed, postal ballot papers should be issued to existing electors who have already successfully applied for a postal vote.
Existing electors who make new postal applications
You should liaise with the ERO (where you are not already the ERO) to ensure you obtain the information on any electors who later apply for a postal vote by the relevant absent vote deadline.
New electors who made postal vote applications alongside their registration application
The ERO must publish two interim election notices of alteration before publishing the final election notice of alteration 5 working days before the poll.3
This supports the dispatch of postal votes at an early stage in the timetable to those electors who have applied to register close to the registration deadline, as you are only able to issue a postal vote to someone who has already been added to the register.
Our election timetable for the Senedd elections also includes the relevant publication dates.
You can find a Senedd election timetable in the absent voting section of our resources page.
Cross-boundary constituencies
In the case of a constituency that covers more than one local authority, you should liaise with the ERO(s) at any other local authority as soon as possible to ensure you obtain the relevant data for any new electors who have successfully applied to vote by post.
