Thames Water Utilities Limited, in short
Who does Thames Water Utilities Limited award contracts to?
Across 198 contracts recorded since 2021, Thames Water Utilities Limited has used 191 different suppliers. The most frequent are BALMORAL TANKS LIMITED (3 contracts), Gel Engineering Limited (3 contracts), Stortec Engineering Ltd (3 contracts).
What does Thames Water Utilities Limited buy?
Its most active procurement categories are financial and insurance services, construction works, construction materials and structures. Categories are derived from the CPV codes published on each award notice.
When do Thames Water Utilities Limited contracts come up for renewal?
1 contract awarded by Thames Water Utilities Limited has an end date within the next 18 months, the earliest on 31 May 2027. End dates come from the original award notices, so they are visible well before any re-tender is advertised.
How much does Thames Water Utilities Limited spend on contracts?
The median published contract value is £4.0bn, across the 18 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 Thames Water Utilities Limited tenders?
Tender Radar monitors Find a Tender, Contracts Finder, Public Contracts Scotland and Sell2Wales each weekday morning and can score every new Thames Water Utilities Limited 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 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 were falling but rose in the last year. Contracts by publication date in the 12 months to 8 Nov 2026 and the two years before it, oldest first: 99, 25 and 60. A change of more than 15% counts as a rise or fall; each year needs at least 5 contracts.
- 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 60 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 23 Oct 2026 (2 weeks ago).
- Values: value figures cover the 18 of 198 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.
