Supplies and services threshold
Works threshold
Above the relevant threshold, we will carry out a competitive tender and advertise on the Find a Tender service, or make use of a suitable central government framework let by Crown Commercial Service, where one is available. For these above-threshold contracts a Contract Award Notice will subsequently be published, giving details of the winning tender, including the name of the supplier and the overall contract value.
For all awarded contracts valued at £12,000 or more (including VAT), contract details notices are also published on the Find a Tender service website.
For contracts awarded via frameworks or dynamic purchasing systems which were in existence before February 2025, the previous regulations continue to apply, and contract award notices will continue to be published on Contracts Finder
