The refurbishment of the 96-metre, 160-year-old tower has been underway since August and is set to continue for four years. When the renovation works began, Big Ben was switched off to ensure the safety of workers.
Hundreds of people stood in silence along Westminster Bridge and Parliament Square on August 22 to observe the grand bell's final bongs, breaking into applause once it ringing.
Apart from repairing and redecorating the interior of the building, the current renovation project includes restoring the clock face's surrounds to their original colours as designed by architects Charles Barry and Augustus Welby Pugin.
But Big Ben will chime again on upcoming special occasions, including Armistice Day on November 11, Remembrance Sunday the following day, and throughout the Christmas holiday season.
Londoners are used to the tower's chimes sounding daily on the radio, often before news bulletins and in the run-up to important announcements. Many residents set their watches by the bells, but Parliamentary authorities cautioned that there could be "slight inaccuracies" after an 11-week break.
"It has always been the intention throughout the Elizabeth Tower conservation works for Big Ben to ring out for important national events, and whenever we safely can without disruption to the refurbishment project," the UK Parliament said in a statement.
