Trestec for public sector suppliers
Public buyers ask suppliers for evidence on resilience, security, modern slavery, carbon and social value. Trestec keeps your own supplier records and evidence in order so you can answer with confidence.
Third party risk in public sector suppliers
Firms that deliver public services often depend on their own subcontractors for delivery, technology and staffing. Buyers expect you to manage that chain, and a failure in it can become a public service failure.
Buyer evidence requests
Tenders and contract reviews ask for resilience, security and sourcing evidence at short notice.
Subcontractor failure
The collapse or failure of a subcontractor can stop delivery of a public service.
Cyber attacks on delivery partners
Attacks on a supplier that holds public data or runs public services disrupt citizens directly.
Responsible sourcing
Modern slavery, carbon reduction and social value commitments must be backed by records.
When a supplier fails
Publicly reported events that show how disruption travels through third parties.
January 2018
Carillion
Carillion, a major government contractor, went into compulsory liquidation, putting hospital, school and facilities contracts and thousands of subcontractors at risk.
March 2023
Capita cyber attack
A cyber attack on Capita disrupted services and exposed data affecting public sector and pension scheme clients.
June 2024
Synnovis ransomware attack
A ransomware attack on Synnovis, a pathology provider to NHS trusts in south east London, disrupted blood tests and led to thousands of postponed appointments and procedures.

Master register
Trestec in public sector supply: feature by feature
The same platform, applied to the subcontractors, technology providers and staffing partners behind your public contracts.
Supplier register and tiering
Every subcontractor, technology provider and staffing partner in one record, with an owner, tags and a change history, tiered by your own rules.

Tag subcontractors by the public contract they deliver, so a buyer's question about one contract is answered from one view.
Important services mapping
Link suppliers to the services you deliver, so you can see which subcontractors each one depends on.

In public sector supply
Collect Cyber Essentials certificates, carbon reduction plans and modern slavery policies from subcontractors, with dates checked.
Companies House monitoring
For UK registered suppliers, a change in company status on Companies House, such as liquidation or administration, raises an urgent alert.
In public sector supply
A cleaning subcontractor on a council contract enters administration, and an urgent alert is raised on that supplier.
Contract analyser and renewal alerts
Contracts are read for liability, termination, exit, renewal and other clauses, with each finding linked to the source text, and renewal dates raise alerts.
In public sector supply
Check that subcontracts carry the termination and exit terms your public contract requires, and see when each one renews.
Exit strategies and continuity plans
Trestec works out which suppliers need an exit strategy and raises a task when one is missing, and continuity plans are kept in a register.
In public sector supply
Show a buyer how delivery would continue if a key subcontractor failed, from a documented exit strategy and continuity plan.

How it works for public sector suppliers
Illustrative example. The company, suppliers and events are invented to show how the features fit together.
- 01
A subcontractor's status changes
Companies House monitoring shows that a facilities subcontractor has entered administration, and raises an urgent alert.
- 02
The team sees what it delivers
The supplier record shows the public contracts and services it supports, its contract terms and any continuity plan on file.
- 03
The exit strategy is opened
The documented exit strategy shows the alternative subcontractor and the steps agreed. If none existed, a task would already be open.
- 04
The replacement is checked
A due diligence request goes to the alternative subcontractor for its insurance, Cyber Essentials and modern slavery evidence.
- 05
The buyer is kept informed
A summary drafted with TresAI and an export of the relevant records support the update to the contracting authority.
