NATIONAL ENERGY SYSTEM OPERATOR LIMITED, in short
Who does NATIONAL ENERGY SYSTEM OPERATOR LIMITED award contracts to?
Across 55 contracts recorded since 2021, NATIONAL ENERGY SYSTEM OPERATOR LIMITED has used 19 different suppliers. The most frequent are DLA Piper (UK) LLP (3 contracts), Efficio Limited (3 contracts), Addleshaw-Goddard LLC (2 contracts).
What does NATIONAL ENERGY SYSTEM OPERATOR LIMITED buy?
Its most active procurement categories are IT services, business and professional services, software and information systems. Categories are derived from the CPV codes published on each award notice.
When do NATIONAL ENERGY SYSTEM OPERATOR LIMITED contracts come up for renewal?
7 contracts awarded by NATIONAL ENERGY SYSTEM OPERATOR LIMITED have an end date within the next 18 months, the earliest on 1 Feb 2027. End dates come from the original award notices, so they are visible well before any re-tender is advertised.
How much does NATIONAL ENERGY SYSTEM OPERATOR LIMITED spend on contracts?
The median published contract value is £2.5m, across the 17 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 NATIONAL ENERGY SYSTEM OPERATOR LIMITED tenders?
Tender Radar monitors Find a Tender, Contracts Finder, Public Contracts Scotland and Sell2Wales each weekday morning and can score every new NATIONAL ENERGY SYSTEM OPERATOR 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 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 in the last year. Contracts by publication date in the 12 months to 7 Nov 2026 and the year before it, oldest first: 35 and 21. A change of more than 15% counts as a rise or fall; each year needs at least 5 contracts.
- 1 contract ends in the next 6 months: Published end dates between 7 November 2026 and 7 May 2027, each contract counted once.
- Has published 12 planned procurements: Pipeline notices on Find a Tender whose expected tender date is still to come, or passed in the last 30 days.
- Took on 19 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 12 Oct 2026 (3 weeks ago).
- Values: value figures cover the 17 of 55 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.
