Are Your Approved Suppliers Still Actually Approved? | Supplier Compliance

Introduction

Most construction businesses have some form of approved supplier list.

Before a new supplier or subcontractor is added, they may be asked to complete a Pre-Qualification Questionnaire (PQQ), provide insurance certificates, demonstrate relevant experience and submit evidence of accreditations, policies and competency.

Everything is reviewed.

The supplier meets the required standard.

They become approved.

But what happens next?

Six months pass.

Then a year.

Then three years.

The supplier's name is still sitting on the approved list.

But are they actually still approved based on the information you have today?

That's a very different question.

Supplier Approval Isn't Permanent

One of the biggest problems with treating supplier approval as a one off exercise is that businesses don't stand still.

A supplier that met every requirement when they were initially assessed may look very different several years later.

Their insurance may have changed.

Certifications may have expired.

Key employees may have left.

Their financial position may have changed.

Their business may have grown, contracted or moved into different areas of work.

Their performance on your own projects may also tell you things that weren't known during the original assessment.

An approved supplier list is therefore only as reliable as the information behind it.

When Was Your Supplier Last Assessed?

This is perhaps the simplest question procurement and supply-chain teams can ask.

When did we last properly assess this supplier?

Not: "When were they added to the database?"

Or: "When did somebody last use them?"

But when was the information supporting their approval actually reviewed?

If the answer is unclear, the supplier's approved status may provide less reassurance than it appears to.

An approval decision made several years ago using information that has never been revisited is ultimately a historic decision.

Insurance Doesn't Stay Current Forever

Insurance is one of the clearest examples of why supplier compliance needs ongoing management.

Employers' Liability, Public Liability, Professional Indemnity, Product Liability and other relevant policies have renewal dates.

A supplier might have provided completely valid documentation during onboarding.

Once that policy expires, however, the evidence you originally assessed no longer demonstrates their current position.

The challenge becomes even greater across a large supply chain.

If 300 suppliers each hold several insurance policies with different expiry dates, that's potentially hundreds of renewals requiring attention throughout the year.

Without a structured process, keeping track can quickly become a significant administrative task.

Certifications and Accreditations Change Too

The same principle applies to certifications, accreditations and memberships.

Depending on the type of supplier and work being undertaken, organisations may collect evidence relating to areas such as health and safety, quality management, environmental management or relevant industry schemes.

Some have expiry or renewal dates.

Others may change status.

Simply recording that a supplier held a particular certification when they first joined your supply chain isn't necessarily enough.

What matters is whether the evidence remains relevant and current when you rely on that supplier again.

A PQQ Is a Snapshot in Time

A Pre-Qualification Questionnaire provides valuable information about a supplier.

But it's important to remember what it represents:

a snapshot of that business at a particular point in time.

The responses may cover areas such as:

• Company information
• Financial details
• Health and safety
• Insurance
• Quality
• Environmental management
• Competence and experience
• Policies and procedures

Those answers don't automatically remain accurate forever.

This is why PQQs need an appropriate review and renewal process.

It doesn't necessarily mean asking suppliers to start again from the beginning every year. Where appropriate, previously supplied information can be reviewed and updated, focusing attention on what has actually changed.

Compliance Is Only Part of the Picture

There's another important limitation to an approved supplier list.

A supplier can remain completely compliant on paper and still perform poorly.

They might have:

• Current insurance
• Relevant accreditations
• Appropriate policies
• Strong PQQ responses

But what happened when they actually arrived on site?

Were they reliable?

Did they meet programme requirements?

Was the quality of their work acceptable?

How did they perform on health and safety?

Were defects dealt with effectively?

Was communication good?

Supplier approval should therefore consider more than whether the correct documents have been uploaded.

Compliance tells you whether a supplier meets your requirements. Performance tells you what they're actually like to work with.

Both can influence future appointments.

Financial Risk Can Change Quickly

A supplier's financial position can also change significantly after initial approval.

Construction operates within complex supply chains, often involving businesses working on multiple projects with tight margins and significant cash flow demands.

Financial information reviewed during onboarding provides useful context at that point in time, but it doesn't guarantee the same position several years later.

For strategically important or higher risk suppliers, organisations may therefore choose to review financial information more regularly.

The appropriate approach will depend on the relationship, value, dependency and level of risk involved.

Not Every Supplier Needs the Same Level of Monitoring

Continuous supplier management doesn't mean creating unnecessary administration.

A small supplier providing a low risk service doesn't necessarily require exactly the same monitoring as a subcontractor responsible for a major package of work.

A risk-based approach can help businesses decide where greater oversight is appropriate.

Factors might include:

• Type of work
• Contract value
• Health and safety risk
• Financial exposure
• Criticality to project delivery
• Previous performance
• Specialist competence
• Reliance on further subcontracting

The objective isn't to collect more information for the sake of it.

It's to maintain the right information for the level of risk involved.

From Approved Supplier List to Active Supply Chain

Perhaps the bigger question is whether the traditional concept of an approved supplier list is still enough.

The word "list" suggests something relatively static.

A supplier is added.

Their details sit there.

Someone searches for them when they're needed.

But modern supply-chain management needs to be much more active.

Instead of simply knowing who is approved, teams increasingly need to understand:

• Who is currently compliant?
• What's approaching expiry?
• Who is undergoing assessment?
• Which suppliers have performed well?
• Where are the emerging risks?
• Which suppliers need further review?
• What has changed since the previous assessment?

That turns an approved supplier list into something far more valuable:

an actively managed supply chain.

Watch the Warning Signs

Supplier status doesn't always change overnight.

Often there are warning signs first.

Perhaps an insurance renewal hasn't been provided.

A certification has expired.

A PQQ hasn't been updated.

Financial information raises questions.

Project performance has deteriorated.

Or required documentation is repeatedly difficult to obtain.

Looking at these signals together gives supply-chain teams an opportunity to investigate issues before making another appointment.

The goal isn't automatically to remove a supplier when something changes.

It's to ensure the business has enough current information to make an informed decision.

Make Renewal Easier for Suppliers Too

There is another side to this process.

Supplier compliance can create a significant administrative burden for subcontractors, particularly when they're supplying similar information to multiple clients.

A good renewal process shouldn't require suppliers to repeatedly enter information that hasn't changed.

Where possible, existing information should be retained so suppliers can review their previous responses, update what has changed and provide new evidence where required.

That makes compliance easier for the supplier while still allowing the supply-chain owner to maintain current records.

Good supplier management should work for both sides.

How Mobilize Supports Ongoing Supplier Management

Liaison's Mobilize platform helps construction organisations manage suppliers beyond the initial onboarding process.

Supplier information, PQQs, assessments, compliance documentation and other relevant records can be managed within one environment, helping teams maintain visibility of their supply chain.

Rather than an approved supplier simply disappearing onto a spreadsheet until somebody needs them again, organisations can maintain a clearer understanding of supplier status and the information supporting it.

Mobilize can support organisations with:

• Supplier onboarding
• Pre-Qualification Questionnaires
• Supplier assessments
• Compliance information
• Project assessments
• Sustainability assessments
• Tender management
• Reporting

This helps turn supplier approval from a one-time administrative exercise into an ongoing supply-chain management process.

Questions to Ask About Your Approved Supplier List

If you're responsible for procurement or supply-chain management, there are a few simple questions worth considering.

When was each supplier last assessed?

Which documents are approaching expiry?

Are PQQ responses still current?

Have any certifications changed?

Do we know how suppliers have actually performed?

Are there suppliers we haven't used for several years?

Are higher-risk suppliers receiving greater oversight?

Can our team quickly identify suppliers requiring attention?

And perhaps most importantly:

Would we confidently approve every supplier on our approved list again today?

If the answer isn't clear, it may be time to review how approval is being managed.

Conclusion

Getting a supplier approved is important.

Keeping them approved is just as important.

Businesses change, documents expire, risks develop and performance evolves.

An approved supplier list should therefore never be treated as a finished piece of work.

The strongest supply chains are continually reviewed, updated and understood.

Because the question isn't simply: "Was this supplier approved?"

It's: "Would we approve them based on what we know today?"

And that's the question that really matters.
