Division bell

In the United Kingdom, division bells are used in the immediate neighbourhood of the Palace of Westminster (housing Parliament) to signal that a division is occurring and that members of the House of Commons or of the House of Lords have eight minutes to get to their chosen division lobby to vote for or against the resolution. The call for a division is also displayed on annunciator screens throughout the Palace of Westminster.^[4][5] The division bells are also sounded at the start of a daily sitting, at the end of the two-minute prayers that start each day, and when the house rises.^[2] Division bells have been used in this way in the United Kingdom since 1858.^[6][7]

As of 2014, there were 384 division bells within the Parliamentary estate, and 172 outside it.^[5] Bells outside of the parliamentary estate are undergoing a phase out as of 2021.^[7]

Some Members may be in nearby offices, restaurants, pubs or shops, and therefore some of these establishments have their own division bells connected to those in the Houses of Parliament. MPs including Alec Douglas-Home, Michael Portillo and Michael Heseltine reportedly had division bells fitted in their homes.^[6]

Though the Commons and Lords share division bells, they are driven from separate ringing generator systems, so that the bells make noticeably different ring patterns for a division of the House of Commons and a division of the House of Lords.^[7]

The generator for the House of Commons simultaneously sounds all the division bells with a 2 Hertz signal (i.e., twice per second) for exactly eight minutes, though this has been varied by the House of Commons in response to the COVID-19 pandemic.^[7] As soon as the bells stop, the door keepers manning the entrances to the two division lobbies close and lock the doors. Any member who has failed to enter the lobby in time has lost the opportunity to vote in that division. Thus anywhere within an eight-minute journey of the Palace of Westminster is often said to be in the "division-bell area".^[6]

A broadcast of the BBC's Antiques Roadshow in October 2007 from the Banqueting House in Whitehall featured the original Ringing Generator System Number 1 from the House of Commons. The programme's expert, Paul Atterbury, with the help of former House of Commons Speaker Baroness Betty Boothroyd, demonstrated the apparatus in use with one of the original Division Bells. The show valued the transmitter at £15,000.

Three Ringing Generator Systems were made at the end of the 19th century by the GPO at the request of the Government. They were numbered 1, 2 and 3. Numbers 2 and 3 were destroyed by a bomb in 1941 and replaced with copies bearing the numbers 4 and 5. Number 5 generator exists, but the whereabouts of number 4 is not known. The current generator is entirely electronic.^{[citation needed]}

There are 172 division bells located outside the Palace of Westminster, in nearby government offices and even MP's private residences.^[6] Public establishments fitted with division bells (as of 2013) include:^[2]

The bells are connected by telephone lines,^[6] and proprietors of these establishments are responsible for the maintenance of the bells.^[2]
