Delivering the annual canvass - England

Which register should I use for an election in December following the publication of the revised register?

There is no provision to postpone publication of the revised register as a result of an election that will take place after the 1 December. 

The revised register has immediate effect on publication for all elections, this is unlike a notice of alteration which only has effect at an election if published on or before the fifth working day before the poll.

Once you have published the revised register it will be used for polling purposes for any election with a polling day on or after the date of publication, although you are also required to publish two interim election notices of alteration and a final notice of alteration on the fifth working day before the poll.1  The nomination of candidates will be based on the register in force on the last date for publication of the notice of election.
