text: United Kingdom In the UK voter registration is compulsory, but the requirement to register is rarely enforced. The 2023 system of registration in the United Kingdom (UK), is known as rolling registration. Electors can register with a local authority at any time of the year. This replaced the twice-yearly census of electors, which often disenfranchised those who had moved during the interval between censuses.
  Across the country, the registration of electors is still technically the responsibility of the head of household, a concept which some consider to be anachronistic in modern society. As of 2023, the system is controversial, as it is possible for one person to delete persons who live with them from the electoral roll. As of January 2012, mandatory individual registration, pursuant to the Political Parties and Elections Act 2009, was anticipated.
  A feasibility study for electronic individual voter registration (IVR), based on the experience of other nations, was undertaken by EURIM (Information Society Alliance) in 2010. The final report was released in 2011. According to the House of Commons Hansard from 16 January 2012, the IVR initiative is yet to be implemented in the UK. There was discussion of data from Northern Ireland, where individual voter registration levels significantly decreased following the introduction of an IVR policy.
  In an experiment in Northern Ireland using personal identifiers, such as National Insurance numbers and signatures, the number of registered electors fell by some ten thousand. It was also understood that the new process may have resulted in fictitious voters being dropped from rolls.
