It provided that at every parliamentary election and municipal election, the poll was to remain open from 8 o'clock a.m. to 8 o'clock p.m. It did not apply in places where no poll was held, or in elections to university constituencies. It repealed the Elections (Hours of Poll) Act 1884, and went into force at the end of the enacting Parliament, meaning it first applied for the 1885 United Kingdom general election.
