Network Rail has awarded a £22 million contract to Morgan Sindall Infrastructure to renew the roof panels at London Liverpool Station as well as improving the drainage system of station's Victorian trainshed.

A large area of the roof is covered in lichen growth which allows very little light to enter the station. These lichen covered panels over platforms 1-10, will be replaced to continue to provide essential protection from the elements and make it a lighter, brighter environment for passengers.

And with more frequent and intense rain-storms likely in the coming years as a result of climate change, the roof needs to be resilient to these challenges and allow rainwater to drain away, without overwhelming the drainage system and entering the station environment.

The contract will deliver a package of work that will improve the overall experience for all users and passengers, by allowing more natural light into the station and make the roof resilient to 1-in-10 year storms. The contract includes:

• replacement of the life-expired GRP (glass reinforced plastic) panels at the northern end of the trainshed

• replacement or repair of over 600 Georgian panels and fittings over the southern end of the trainshed and concourse roof

• repair of the aluminium roof sheeting across the whole roof

• improvement to the roof’s catchment and drainage system to accommodate more intense rain events

• repair and restoration of the valance panels on the end of the trainshed roof

From Christmas 2024, these improvements will start to be delivered using an innovative sliding works platform, suspended under the roof spans, and operated from Bishopgate’s Exchange Square.

This approach will minimise disruption inside the station and allow the roof renewal work to take place overhead while allowing the station operations to continue as normal without interruption.
