Summary

British and eligible Irish citizens living overseas can now register to vote in UK Parliamentary general elections no matter how long ago they left or were last registered to vote in the UK.  

An overseas declaration is now valid for three years, lasting until 1 November in the third year after it takes effect (for example, if the declaration takes effect on 1 March 2024, it will expire on 1 November 2026). 

British and eligible Irish citizens living overseas can now register and apply for an absent vote online (not available in Northern Ireland).
