Description

Great British Energy (GBE) is intending to procure a suite of contracts to deliver its Technical and Professional Advisory requirements over the next three years. The value of this programme is £18m (including VAT) and it is anticipated that this budget shall be delivered by two tiered Suppliers.

These Services will be procured through a Competitive Flexible Procedure procurement which is expected to be launched early January 2026 with awards expected in March 2026. The duration of the contracts will be three years, with a formal performance review of all Suppliers around month 18. At this point, mechanisms will be in place should it be required to demote Supplier A and promote Supplier B. Both Contracts will have a maximum value of £18m, which is the maximum value of the programme, but importantly they will be “up to” this value and no commitment for any spend to flow through them. Instead, they will share this programme value with Supplier A delivering the majority of the work through individual commissions or work orders, unless conflicted, reduced resources, ability preventing them from delivery, or performance issues meaning commission(s) would be delivered by Supplier B.

How to engage

GBE are inviting Suppliers for each identified route to market to hear about each requirement in a single event. This will provide an appreciation of how the Services will interact. This event will outline and test the opportunities and does not commit GBE to undertaking these procurements. The intention of the event is to test contractual arrangements and scope with the market to identify opportunities for improvement, hence we would strongly appreciate any participation. GBE will host an online virtual Market Engagement Event which will consist of an online interactive presentation via Microsoft Teams. This will be followed up by a questionnaire to all attendees which we would encourage people to respond to. The event is scheduled to occur 10th December 11:00-12:00 GMT. If you wish to attend, please sign up using the form here: https://forms.office.com/e/bVyzJrqRtX If you are unable to attend the event but would still wish to hear about the opportunities, there is an option to do so in the above form. As a reminder, only those Suppliers awarded a place on the identified Frameworks will be able to submit mini competition responses to these identified due diligence Services. Neither of threse Frameworks are open for new applications. However, the Competitive Flexible Procedure is an open procurement for any Supplier to respond to, run under the conditions established in the Procurement Act 2023. This Notice is informing Suppliers of an Early Market Engagement Event and is not notifying the commencement of a procurement opportunity.
