Procurement Policies & Procedures

The following policies and procedures govern CRL's procurement and delivery activities.


Crossrail Limited (CRL) takes conflicts of interest or potential conflicts of interest seriously.   

Each individual or company who is or wishes to be engaged on the  Crossrail project, whether as a contractor or consultant to CRL as part of the CRL supply chain should be mindful of the obligations owed to CRLregarding conflicts of interest.  From the date of expressing an interest in Crossrail work to completion of Crossrail contracts companies or individuals must notify CRL immediately of any conflict or potential conflict of interest. If in any doubt, a query should be raised with CRL.

CRL’s policy regarding supply chain conflicts of interest is included below.

Enquiries or notifications related to conflicts of interest can be sent to the following email address : [email protected]  provided that matters which are required to be disclosed:

  • in the course of procurement exercises must be notified in accordance with the relevant instructions to tenderers via CRL’s eSourcing system (Bravo)
  • pursuant to awarded contracts should also be notified to the Project Manager, the Employer’s Representative or the contract administrator nominated by CRL in the relevant contract for this purpose.


Companies that have a contract with CRL, or are bidding for a contract, and intend to engage consultants who are or who have been retained by CRL must comply with the attached principles for addressing potential conflicts of interest.

These principles have been prepared by reference to CRL’s Framework Design Contractors (FDCs) but they apply, where relevant, to other consultants and to sub-consultants retained directly or CRL The attached principles have been provided to the FDC’s. and are made available here to help to clarify  generally where conflicts may arise and to give guidance as to the approach which CRL would be minded to adopt upon being notified of the relevant facts. They are not intended to be comprehensive or binding in nature – judgment and discretion has to be exercised by CRL in each case.

In general, the earlier the notification to CRL the easier it is to achieve a satisfactory outcome. Late notification after a conflict of interest has already arisen is more likely to result in parties being excluded from participation in the affected contracts and may have other legal consequences.

Companies expressing an interest in Crossrail work and Tenderersmust comply with the attached principles regarding the engagement of consultants and notify CRL, or seek advice, regarding all actual or perceived conflicts of interest via CRL’s eSourcing system (Bravo). 

FDC’s, other consultants, and all contractors appointed by CRL must comply with the attached principles regarding the engagement of consultants and notify CRL, or seek advice, regarding conflicts of interest via the relevant contract administrator.

CRL abides by the Greater London Authority (GLA) Responsible Procurement Policy.

The policy is a high level strategic document setting out the Group’s plans, ambitions and commitments for ensuring continuous improvement in London delivered through all of its procurement activities. The policy has been drafted by the GLA Group Responsible Procurement Forum (RPF), consulted on up to Deputy Mayor level across the Greater London Authority at Director level across the GLA Group, and approved by the Greater London Authority Group Collaborative Procurement Board (CPB).

For more information, please visit the and read the GLA Group Responsible Procurement Policy.


CRL will trade only with reputable and stable organisations whose delivery capability has been fully assessed and who continue to perform to requirements.

The complexity and scale of the Crossrail programme will require collaborative behaviours from all involved. Crossrail will foster this with its approach to contracts, contract management and in all relationships.

Procurement activities will meet the highest standards of integrity and ethical behaviour whilst meeting both best practice and the best interests of the project. Procurement transactions will be conducted and concluded honestly, fairly and transparently. Procurement practice will be of the highest standard and closely monitored.

CRL has taken action to address the risks of slavery and human trafficking taking place in any part of its supply chain.  The attached Modern Slavery Statement is made pursuant to section 54(1) of the Modern Slavery Act 2015.
