DESNZ, in short
Who does DESNZ award contracts to?
Across 394 contracts recorded since 2021, DESNZ has used 249 different suppliers. The most frequent are Verian Group UK Limited (14 contracts), OVE ARUP and PARTNERS LIMITED (13 contracts), Baringa Partners LLP` (13 contracts).
What does DESNZ buy?
Its most active procurement categories are research and development, architecture and engineering, energy and fuel. Categories are derived from the CPV codes published on each award notice.
When do DESNZ contracts come up for renewal?
50 contracts awarded by DESNZ have an end date within the next 18 months, the earliest on 7 Nov 2026. End dates come from the original award notices, so they are visible well before any re-tender is advertised.
How much does DESNZ spend on contracts?
The median published contract value is £158k, across the 393 contracts that state a value. Published values are not added up here: a framework's value is a ceiling shared by every supplier on it, and the same value is often repeated across lots, so adding them up would overstate what is spent.
How can I be alerted to new DESNZ tenders?
Tender Radar monitors Find a Tender, Contracts Finder, Public Contracts Scotland and Sell2Wales each weekday morning and can score every new DESNZ notice against your organisation's profile, delivering the relevant ones before 9am alongside their contracts approaching renewal.

How these figures are worked out
- The last 12 months: award notices published from 8 November 2025 to 7 November 2026, each contract counted once however many suppliers or rows it has. The same window is used everywhere on this page.
- Year on year: Its published contract awards have fallen in each of the last two years. Contracts by publication date in the 12 months to 7 Nov 2026 and the two years before it, oldest first: 178, 141 and 77. A change of more than 15% counts as a rise or fall; each year needs at least 5 contracts.
- Most of its current contracts end in the next 12 months: 46 of its 85 contracts with an end date still to come end by 7 November 2027. Shown when that is more than half, with at least 5.
- Has awarded contracts every year since 2022: At least one contract in every calendar year from 2022 to 2026, by award date (or publication date where the award date is later). Our records begin in 2021.
- Took on 27 new suppliers in the last 12 months: Suppliers named on a contract it awarded and published since 8 November 2025, and on none before. Counted by organisation, not by spelling.
- Most recent award: recorded 4 Nov 2026 (3 days ago).
- Values: value figures cover the 393 of 394 contracts where a value was published. Values are never added up: framework ceilings and values repeated across lots would make a total meaningless.
- Since 2021: totals count contracts by award date from January 2021, and suppliers by organisation rather than by spelling.
