The rules for verifying who you’re funding or contracting with have changed. The Procurement Act 2023 has been in force since February 2025, the Subsidy Control Act 2022 replaced the old state aid regime, and grant competitions keep attracting more applicants than assessors have time to check by hand. Verification isn’t optional paperwork anymore. It’s the thing that determines whether a procurement decision or a grant award can survive scrutiny.
This guide sets out a practical framework for verifying company eligibility, built for procurement teams and grant administrators who need something usable day-to-day.
Why verifying company eligibility matters
Public accountability and value for money
Public money spent through procurement or grants comes with an obligation to show the recipient was properly checked. A verification process that can be explained and evidenced protects the decision as well as the budget.
Procurement Act 2023 compliance
The Act sets out specific exclusion grounds, a new debarment list, and registration requirements that didn’t exist under the old regime. Meeting these obligations means actually verifying supplier information, since collecting it on a form isn’t enough on its own.
Grant scheme integrity and fraud prevention
Grant applications are self-reported by nature. Independent verification is what catches misstated eligibility, whether that’s deliberate or simply careless, before it becomes public money spent on an ineligible applicant.
Reputational and legal risk protection
A procurement decision or grant award that’s later challenged puts the organisation’s process on display. Weak verification turns a routine dispute into a much bigger problem.
Efficient use of procurement and assessment capacity
Manual verification doesn’t scale to the volumes procurement teams and grant schemes now handle. A structured process means the people doing the checking spend their time on judgement calls, not on repetitive lookups.
The regulatory context in 2026
The Procurement Act 2023
The Procurement Act 2023 came into force on 24 February 2025, replacing the Public Contracts Regulations 2015 and related legislation. It changes what contracting authorities need to check about suppliers and how those checks need to be recorded.
The Central Digital Platform and supplier registration
Suppliers can register on the Central Digital Platform, the enhanced Find a Tender service, from the Act’s commencement date. From April 2026, registration became compulsory for all public sector contracts, including those below the usual thresholds – so the Act’s obligations have arrived in stages rather than all at once, and it’s worth checking which stage applies to a given contract.
Mandatory and discretionary exclusion grounds
The Act expands the exclusion grounds contracting authorities must consider. Mandatory grounds cover convictions for offences including fraud, bribery, money laundering, tax offences, and, new under this Act, corporate manslaughter and cartel involvement. Discretionary grounds cover matters like poor past performance, professional misconduct, and, also new, environmental misconduct. Both categories now extend to a supplier’s connected persons and subcontractors as well as the bidding entity itself.
The debarment list
The Act introduces a centrally managed debarment list. A supplier debarred on mandatory grounds faces exclusion from all public contracting for five years. Checking a supplier against the list, and understanding whether any connected persons appear on it, is now a standard part of eligibility verification.
The Subsidy Control Act 2022 and grant funding compliance
The Subsidy Control Act 2022 replaced the EU state aid regime for UK grant funding. It sets its own eligibility and reporting requirements, meaning grant administrators need to verify a different, though overlapping, set of criteria to the old approach.
The Modern Slavery Act 2015 and section 54 statements
Larger suppliers are required to publish an annual slavery and human trafficking statement under section 54 of the Modern Slavery Act 2015. Checking whether a supplier has published one, and whether it’s current, is a standard part of supply chain due diligence.
Sanctions screening
Screening against the Office of Financial Sanctions Implementation’s consolidated list remains a legal requirement independent of procurement or grant-specific rules. It applies to anyone doing business with a sanctioned entity, including organisations outside the public sector.
