How much does the Westminster palace cost?

There is no precise figure for the total cost of the Westminster Palace, as it has been under continuous construction and renovation over many centuries. The original palace, built in the 11th century, was expanded and rebuilt over the years, with major renovations taking place in the 14th, 16th, and 19th centuries. The most recent significant renovation, following a fire in 1834, cost approximately £1.5 million (equivalent to £138 million in 2023).
