Wates will repair the stonework on the exterior of the Tower to minimise the risk of stone fall. It will also encompass other elements such as conservation works to the window glazing, roof and flagpole. The last significant works on Victoria Tower were completed in the early 1990s.

Since 2018 there have been multiple incidents of stone fall from the exterior of Victoria Tower.

The work is currently scheduled to be completed around 2031 with a contract value of £132.7m, including VAT.

Steve Holbrook, Managing Director at Wates, said: “Wates and Parliament share a commitment to preserving traditional building techniques while embracing innovative construction and logistic methodologies to protect and enhance this historic landmark.

“The extensive repair and restoration work we will be carrying out on the Victoria Tower will ensure it can continue its important role on the parliamentary estate for decades to come.”
