As UK summer temperatures keep breaking records, visitors to Tower Bridge can enjoy a cooler visit now that a new heat-reducing treatment has been applied to its iconic glass High-level Walkways above the Thames.
The coating is added to the existing windows to decrease solar heat gain during warmer weather, enhancing visitor comfort while maintaining the panoramic views of London’s skyline.
The treatment deflects up to 95% of infrared radiation and filters up to 96% of UV rays, while preserving the views that make Tower Bridge a top attraction in the capital.
A heritage-sensitive retrofit
Chris Earlie, director of Tower Bridge, says: “We want every visitor to have the best possible experience when they explore inside Tower Bridge, whatever the weather.
"As London continues to experience warmer summers, this investment will help visitors to enjoy our High-level Walkways in greater comfort during periods of hot weather while, importantly, preserving the spectacular views and the historic character that make Tower Bridge such a memorable day out.”

A visit to Tower Bridge’s High-level Walkways gives visitors the opportunity to walk on glass floors 42 metres above the River Thames. If timed correctly, they can observe a Bridge Lift from a unique, bird’s-eye view.
Afterwards, visitors can explore the Victorian Engine Rooms and learn how this London landmark has operated for over 130 years.
The removable treatment serves as a heritage-sensitive retrofit that enhances the walkway experience without changing the structure's appearance or character.
Nathan Jones, founder and CEO at Restoreo, adds: “This project demonstrates how historic buildings can be adapted for a changing climate without compromising their heritage.
"By enhancing the performance of Tower Bridge’s existing glazing, we’re helping to create a more comfortable experience for the thousands of people who explore inside Tower Bridge every year.”
Record-breaking heat
In June 2026, visitor attractions in the UK and France, including Tower Bridge and the Louvre museum, closed their doors as a record-breaking heatwave swept across western Europe. France registered its hottest day ever, and the UK experienced record heat for June.
Scientists agree that climate change drives extreme weather, such as the record-breaking high temperatures seen this summer in the UK. Heatwaves like this one are now more common and more intense because of human-caused climate change.
In November 2025, ten of the UK’s leading experts briefed an invited audience of more than 1,200 politicians and leaders from business, culture, faith, sport and the media at Westminster. The briefing set out the implications of climate and nature breakdown for health, food systems, national security and the economy.
