Debarment list:
how UK suppliers are barred from tenders
The debarment list is the published list of suppliers that a Minister of the Crown, after an investigation, considers excluded or excludable from UK public procurement. It has existed under section 62 of the Procurement Act 2023 since 24 February 2025.

Who puts a supplier on the debarment list?
Only a Minister of the Crown, after an investigation, and only where an exclusion ground applies.
A Minister may enter a supplier’s name after investigating under section 60, or considering a Welsh or Northern Ireland investigation, and being satisfied that the supplier is excluded or excludable (s.62(1)–(3)).
The Debarment Review Service investigates and recommends on behalf of the Minister; since 1 April 2026 it has been part of the Government Commercial Agency (DRS page).
- Anyone can refer a supplier; the DRS has a discretion, not a duty, to investigate.
- Against the exclusion grounds in Schedules 6 and 7.
- Handled by the National Security Unit for Procurement, not the DRS.
- Investigation reports are published, with limited exceptions.
What does a debarment list entry record?
The exclusion ground, whether it is mandatory or discretionary, any contract description for national security, and the expected end date.
| Field (section 62(4)) | What it tells a buyer |
|---|---|
| The exclusion ground | Which Schedule 6 or 7 ground applies |
| Mandatory or discretionary | Whether the buyer must or may exclude |
| Contract description (national security only) | Which kinds of contract the exclusion covers |
| Expected end date | When the Minister expects the ground to cease to apply |

A supplier’s review sequence, based on the primary sources below. It is not a measured outcome or a prescribed buyer timetable.
How must a buyer use the debarment list?
Check it before letting a supplier take part and before awarding; exclude for a mandatory ground, consider exclusion for a discretionary one.
- Before you start01
Use the current documents
Check the primary publication and later changes before using the sequence below. - Check 202
Check before participation and award
Guidance says buyers should check the list before allowing a supplier to participate and before deciding to award (para 15). - Check 303
Check associated persons and subcontractors
Buyers must check the supplier, its associated persons and intended subcontractors, and should check connected persons too (para 15). - Check 404
Mandatory or discretionary
For a covered procurement, a buyer must exclude a listed supplier on a mandatory ground, with limited exceptions, and may exclude on a discretionary one (DRS page). - Follow through05
Tell the DRS
A buyer that excludes, replaces or removes a supplier must notify the Debarment Review Service (DRS page).
An editorial order of work, not a buyer's fixed timetable. The current notice and documents determine participation and submission.
What happens to a supplier before it is listed?
It gets notice of the decision and its rights, then an eight-working-day debarment standstill.
Before listing, the Minister must notify the supplier of the decision and of its rights under sections 63 to 65, and may not list it until eight working days have passed (s.62(5)–(6)).
If the supplier starts interim relief proceedings in that time and the Minister is told, the name cannot be entered until the proceedings end (s.62(7)).
