United Kingdom National Nuclear Laboratory, in short
Who does United Kingdom National Nuclear Laboratory award contracts to?
Across 91 contracts recorded since 2021, United Kingdom National Nuclear Laboratory has used 101 different suppliers. The most frequent are ATKINSREALIS UK Limited (10 contracts), Amentum Clean Energy Limited (10 contracts), Stantec UK LTD (7 contracts).
What does United Kingdom National Nuclear Laboratory buy?
Its most active procurement categories are research and development, community and personal services, architecture and engineering. Categories are derived from the CPV codes published on each award notice.
When do United Kingdom National Nuclear Laboratory contracts come up for renewal?
25 contracts awarded by United Kingdom National Nuclear Laboratory have an end date within the next 18 months, the earliest on 6 Dec 2026. End dates come from the original award notices, so they are visible well before any re-tender is advertised.
How much does United Kingdom National Nuclear Laboratory spend on contracts?
The median published contract value is £91k, across the 74 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 United Kingdom National Nuclear Laboratory tenders?
Tender Radar monitors Find a Tender, Contracts Finder, Public Contracts Scotland and Sell2Wales each weekday morning and can score every new United Kingdom National Nuclear Laboratory 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 rose in the last year. Contracts by publication date in the 12 months to 7 Nov 2026 and the year before it, oldest first: 33 and 60. A change of more than 15% counts as a rise or fall; each year needs at least 5 contracts.
- 14 contracts end in the next 6 months: Published end dates between 7 November 2026 and 7 May 2027, each contract counted once.
- Took on 74 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 6 Oct 2026 (4 weeks ago).
- Values: value figures cover the 74 of 91 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.
