Colas Rail UK’s Procurement Process

Colas Rail continues to commit to the Government’s SME target of a minimum 33% spend with SMEs. We have exceeded this for the last 3 years, rising to over 40% in 2021/22, based on the contracts currently held, for future years.
Colas Rail commits to pay our SME’s promptly, we were an original signatory to Network Rail’s Fair Payment Charter, and happy to support the Governments Prompt Payment Code.

We adhere to five key actions:



Colas Rail are keen to obtain the best suppliers to support our delivery portfolio. If you have a product or services that will help drive efficiency and effectiveness in the railway,


Thorough assessment of suppliers and their safety practices and through audit and demonstration of their proven capability and competency to keep people safe for all activities including those on or near the line.


Regular communication with our supply chain. Once appointed Colas Rail ensure that we maintain regular dialogue to ensure that our requirements are fully understood, that good safety behaviours are embedded, and documentation is approved in advance of works commencing.


Performance will be monitored through leading KPIs and ‘League Tables’ that are visible and verifiable.


Where appropriate, and in line with our Ethics policy, we will incentivise suppliers to attain excellence, recognising their efforts and contribution to improved performance whether this is safety, financial, technical, environmental or social value.
