House of Commons backed funding for the project

A 10-year schedule of maintenance work, including new plumbing, wiring, boilers, and radiators, and the installation of solar panels on the roof, has been estimated to cost £369 million and was approved by the prime minister in November 2016. It will be funded by a temporary increase in the Sovereign Grant paid from the income of the Crown Estate and is intended to extend the building's working life by at least 50 years. In March 2017, the House of Commons backed funding for the project by 464 votes to 56.
