By-election timetables - Commons Library Standard Note

Published 10 September 2014 | Standard notes SN06609

Authors: Isobel White

Topic: By-elections, Elections

The Electoral Registration and Administration Act 2013 made provision to increase the length of Parliamentary election timetables, both for general and by-elections. This provision was brought into force on 6 April 2014 by article 3 of the Electoral Registration and Administration Act 2013 (Commencement No. 5 and Transitory Provisions) Order 2014. Parliament will now be dissolved 25 rather than 17 working days before the general election on 7 May 2015. The by-election timetable is now between 21 and 27 working days from the issuing of the writ (it had previously been between 13 and 19 days).

For the details of by-elections since the last general election see Library Standard Note 5833 By-elections since 2010.
