Section six. Complementary information

six.3) Additional information

The Authority is holding a Market Information Day (MID) to engage contractors by explaining the opportunities associated with the works and to invite views from interested contractors for the delivery of the EfW Facility decommissioning, demolition and associated works as set out in this PIN. It is planned that the MID will be held week commencing 9 October 2023 in central London. The Authority will give a presentation on its proposals for the work including the planning requirements, the Authority's circular economy principles, interaction with LondonEnergy Ltd (the current operator of the EfW Facility), the proposed works programme and any engagement required between the contractor/contractors, the operator and regulatory parties. The MID will also include site visits to give suppliers the opportunity to see the site early in the procurement process and to help them understand the constrained nature of the site. Following the MID, the Authority will offer post-event interviews or questionnaires to the contractors to gather feedback and to discuss the contractors' suitability for the works. The Authority and contractors will discuss: the services the contractors might be able to provide in-house versus which services would be sub-contracted; acceptable levels of risk to the contractors; the level of information the contractors require in order to tender; the surveys the contractors may need to base their tender on; and the timelines and practicalities of the works for each contractor.

Interested contractors that would like to attend the MID should register by completing the meeting request form which is available here:


Further information is available on the Authority's website:


All completed forms must be submitted no later than Friday 25 August 2023 at 16.59. Details about access to the event will subsequently be communicated to contractors that express an interest to attend.
