LONDON — British Parliament officials said Wednesday they will review plans to silence Big Ben during four years of repairs after senior politicians criticized the lengthy muting of the beloved bell.

When the repairs were announced last year, officials said the massive bell in Parliament’s clock tower would be silenced for several months. But this week they said the ringing pause would last until 2021.

Prime Minister Theresa May said ‘‘it can’t be right for Big Ben to be silent for four years.’’

The 13.7 metric ton bell has sounded the time almost uninterrupted since 1859, but it’s due to fall silent on Monday so repairs can be carried out on the Victorian clock and the Elizabeth Tower.

Officials say the silencing is needed to ensure the safety of workers.

Adam Watrobski, principal architect at the Houses of Parliament, rejected claims that the great bell that survived German bombing raids was the victim of overcautious health and safety regulations.

‘‘It is quite simply that we can’t have the bells working with those people adjacent to it. It simply isn’t practical to do that,’’ he said.

In a statement Wednesday headlined ‘‘update on Big Ben’s bongs,’’ Parliament officials said that in light of the concerns expressed by lawmakers, authorities ‘‘will consider the length of time’’ Big Ben is stifled.
