A major conservation project is set to get underway at Big Ben in London.



With scaffolding works nearly completed, the bongs of Big Ben will sound for the last time on Monday, 21 August.



Pre-construction services on the four-year programme are being delivered by Sir Robert McAlpine. Once scaffolding reaches the necessary height, work will begin at the very top of the Tower with the renovation of the Ayrton Light and the refurbishment of the cast iron roofing.

The team will then work their way down the building, removing scaffolding as they go, and tackling a wide range of the complex issues created by the height and heritage of the landmark. The Great Clock itself will be dismantled piece by piece with each cog examined and restored. The four dials will be carefully cleaned, the glass repaired, the cast iron framework renewed, and the hands will be removed and refurbished.


While the Great Clock and the dials are undergoing conservation, it will be necessary to cover the faces for some time. However one working clock face will remain visible at all times throughout the works, to ensure the public are still able to set their watches.

Steve Jaggs, Keeper of the Great Clock, said: "Big Ben falling silent is a significant milestone in this crucial conservation project. As Keeper of the Great Clock I have the great honour of ensuring this beautiful piece of Victorian engineering is in top condition on a daily basis.

"This essential programme of works will safeguard the clock on a long term basis, as well as protecting and preserving its home – the Elizabeth Tower. Members of the public are welcome to mark this important moment by gathering in Parliament Square to hear Big Ben’s final bongs until they return in 2021."
