The notices, as their publishers wrote them.
Read from Contracts Finder and Find a Tender. Every row links to the publisher's own notice. The record is the UK's two public notice services: Find a Tender and Contracts Finder, read for every publication day from 5 Aug 2026 to 3 Nov 2026. Edition of 4 Nov 2026.
Published is the date on the notice. Read is the day BuzzBaboon first retrieved it. Last checked is the latest retrieval that still carried it.
One contract, one row. A tender, its changes and its award share one procurement id, so they are one row at the latest stage, with the tender deadline kept. A notice published on both services is one row with both links.
Open means open. A tender is shown as open only while its deadline is today or later, by your own date, not the date the record was built. A passed deadline is closed.
A record of notices, not a forecast.
What is not in the record: no supplier names, no value that the notice does not state, and no forecast.
Award notices name the winning supplier at source. These pages do not, and where a supplier's name is written into a title it is shown as [supplier]; the link to the notice still names it. A value appears only where the notice states one, in the currency it states, and it is often a framework ceiling rather than a spend. A contract end date is the initial term; extensions are on the notice where they are stated. Awards are those published in the window, so a contract awarded before it is not in the list of contracts ending.
Product families are matched from the notice's CPV codes by the same rule as the Buyer Book, and are approximate. Contains public sector information licensed under the Open Government Licence v3.0.
Follow this buyer.
Following a buyer is not built yet. If it is built, it would tell you when Department for Energy Security & Net Zero publishes a new tender or early engagement notice. Leave an address and you will hear when it exists, and nothing else.
