UK Hydrographic Office, in short
Who does UK Hydrographic Office award contracts to?
Across 391 contracts recorded since 2021, UK Hydrographic Office has used 238 different suppliers. The most frequent are IIC Technologies Limited (14 contracts), Radley Yeldar Limited (14 contracts), ENVITIA Ltd (14 contracts).
What does UK Hydrographic Office buy?
Its most active procurement categories are IT services, business and professional services, architecture and engineering. Categories are derived from the CPV codes published on each award notice.
When do UK Hydrographic Office contracts come up for renewal?
55 contracts awarded by UK Hydrographic Office have an end date within the next 18 months, the earliest on 31 Dec 2026. End dates come from the original award notices, so they are visible well before any re-tender is advertised.
How much does UK Hydrographic Office spend on contracts?
The median published contract value is £75k, across the 390 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 UK Hydrographic Office tenders?
Tender Radar monitors Find a Tender, Contracts Finder, Public Contracts Scotland and Sell2Wales each weekday morning and can score every new UK Hydrographic Office 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 fell, then stayed broadly level in the last year. Contracts by publication date in the 12 months to 7 Nov 2026 and the two years before it, oldest first: 48, 28 and 31. A change of more than 15% counts as a rise or fall; each year needs at least 5 contracts.
- 20 contracts end in the next 6 months: Published end dates between 7 November 2026 and 7 May 2027, each contract counted once.
- Has published 2 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 2021: At least one contract in every calendar year from 2021 to 2026, by award date (or publication date where the award date is later). Our records begin in 2021.
- Took on 14 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.
- Has published 1 AI transparency record: Algorithmic Transparency Recording Standard records on GOV.UK, listed further down this page.
- Most recent award: recorded 7 Oct 2026 (4 weeks ago).
- Values: value figures cover the 390 of 391 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.
