“A programme of essential works to conserve the Elizabeth Tower, the Great Clock and the Great Bell, also known as Big Ben began in early 2017. The total overall cost of the project, including VAT, Risk and Optimism Bias and transferred fire safety work costs, is now estimated at £61m as opposed to £29m as estimated in spring 2016. To ensure that the UK’s most famous clock continues to keep time, our experts closely monitor the mechanism and carry out adjustments on a daily basis. The Elizabeth Tower, which is visited by around 12,000 people each year, is carefully conserved by Parliament’s heritage team. However, as extensive conservation works were last carried out more than 30 years ago (1983-1985), significant work and an investment of £61m is now required to ensure it remains in good condition and is safeguarded for future generations. As the Tower is 96 metres tall, scaffolding is needed to enable workers to reach high levels safely. Scaffolding will be dismantled as the work is completed from the top, and at least one clock face will be on show at all times. As a Grade I listed building within a UNESCO World Heritage site, the 160-year-old Tower is subject to listed building consent. This programme of works has been carefully planned in consultation with Historic England.
These works will: •Repair problems identified with the Elizabeth Tower and the Great Clock, which cannot be rectified whilst the clock is in action
•Conserve significant elements of the Tower, as designed by architects Charles Barry and Augustus Wellby Pugin
•Repair and redecorate the interior, renew the building services and carry out work to improve health and safety and fire prevention
•Increase energy efficiency to reduce the Tower’s environmental impact”
