Submarine Delivery Agency, in short
Who does Submarine Delivery Agency award contracts to?
Across 26 contracts recorded since 2021, Submarine Delivery Agency has used 22 different suppliers. The most frequent are M Subs Limited (2 contracts), NESC Limited (2 contracts), Marine Rescue Technologies Ltd (2 contracts).
What does Submarine Delivery Agency buy?
Its most active procurement categories are business and professional services, community and personal services, security and defence. Categories are derived from the CPV codes published on each award notice.
When do Submarine Delivery Agency contracts come up for renewal?
9 contracts awarded by Submarine Delivery Agency have an end date within the next 18 months, the earliest on 14 Dec 2026. End dates come from the original award notices, so they are visible well before any re-tender is advertised.
How much does Submarine Delivery Agency spend on contracts?
The median published contract value is £464k, across the 26 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 Submarine Delivery Agency tenders?
Tender Radar monitors Find a Tender, Contracts Finder, Public Contracts Scotland and Sell2Wales each weekday morning and can score every new Submarine Delivery Agency notice against your organisation's profile, delivering the relevant ones before 9am alongside their contracts approaching renewal.

Same type of body. National bodies are not grouped by region: a department's notice address is where its commercial team sits, not where it works. Most published awards first.
How these figures are worked out
- The last 12 months: award notices published from 9 November 2025 to 8 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 8 Nov 2026 and the year before it, oldest first: 11 and 21. A change of more than 15% counts as a rise or fall; each year needs at least 5 contracts.
- 6 contracts end in the next 6 months: Published end dates between 8 November 2026 and 8 May 2027, each contract counted once.
- Has published 5 planned procurements: Pipeline notices on Find a Tender whose expected tender date is still to come, or passed in the last 30 days.
- Has awarded contracts every year since 2024: At least one contract in every calendar year from 2024 to 2026, by award date (or publication date where the award date is later). Our records begin in 2021.
- Took on 18 new suppliers in the last 12 months: Suppliers named on a contract it awarded and published since 9 November 2025, and on none before. Counted by organisation, not by spelling.
- Most recent award: recorded 15 Oct 2026 (3 weeks ago).
- Since 2021: totals count contracts by award date from January 2021, and suppliers by organisation rather than by spelling.
