How to Review a Supplier’s Insurance Certificate (Step-by-Step Guide)

What Is an Insurance Certificate?

An insurance certificate is a document that confirms a supplier holds valid insurance cover.

In UK construction, the most common types include:

• Employers’ Liability (EL)
• Public Liability (PL)
• Professional Indemnity (PI)

👉 These are typically required as part of PQQs, audits, and contract compliance.

Why Proper Review Matters

Failing to properly review insurance documents can result in:

• Working with uninsured or underinsured suppliers.
• Financial exposure in the event of a claim.
• Breach of contract or framework requirements.
• Project delays or legal issues.

👉 A quick check is not enough, documents must be validated carefully.

Step-by-Step: How to Review a Supplier’s Insurance Certificate

1. Check the Supplier Name Matches Exactly

Ensure the name on the certificate:

• Matches the legal entity you are contracting with
• Includes correct spelling and company structure (Ltd, LLP, etc.)

👉 Mismatched names may invalidate cover.

2. Confirm the Type of Insurance

Check that the supplier holds the correct policies:

• Employers’ Liability (required by UK law if they employ staff)
• Public Liability
• Professional Indemnity (if providing design/advisory services)

👉 Missing policy types are a major red flag.

3. Verify the Level of Cover

Review the indemnity limits carefully.

Typical minimums (may vary by project):

• EL: £10 million
• PL: £5–10 million
• PI: £1–5 million

👉 Ensure limits meet your contract or framework requirements.

4. Check the Policy Dates

Look for:

• Start date
• Expiry date

👉 The policy must:

• Be currently valid
• Cover the full duration of the project (or be renewable)

⚠️ Expired or soon-to-expire policies are a common issue.

5. Review the Insurer Details

Confirm that:

• The insurer is reputable
• The policy number is clearly stated

👉 Unknown or unverified insurers may increase risk.

6. Check for Policy Exclusions

Many people skip this, but it’s critical.

Look for exclusions that could affect your project, such as:

• Specific types of work not covered
• Height restrictions
• Hazard exclusions

👉 A policy may exist but still not cover your project.

7. Ensure Activities Match the Work

Check that the insurance covers the type of work being carried out.

For example:

• Construction activities
• Design services
• Specialist installations

👉 If the activity isn’t covered, the policy may be invalid for your project.

8. Confirm Employers’ Liability Compliance

In the UK:

• EL insurance must meet legal requirements
• Certificates should reference compliance with UK legislation

👉 This is a legal requirement, not just best practice.

9. Request Supporting Documents (If Needed)

If anything is unclear, request:

• Full policy wording
• Broker confirmation
• Updated certificates

👉 Never assume, always verify.

10. Record and Track Expiry Dates

Once reviewed:

• Log the expiry date
• Set reminders for renewal
• Store documents centrally

👉 This prevents compliance gaps later in the project.

Insurance Review Checklist

Use this quick checklist when reviewing supplier insurance:

• Supplier name matches legal entity
• Correct insurance types in place (EL, PL, PI)
• Indemnity limits meet requirements
• Policy is valid and in date
• Insurer is reputable
• No critical exclusions
• Activities align with project scope
• Supporting documents verified (if required)
• Expiry dates recorded and tracked

Common Mistakes to Avoid

• Accepting expired certificates
• Not checking indemnity limits
• Ignoring exclusions
• Failing to match company names
• Not tracking renewal dates
• Assuming “certificate = compliant”

Pro Tip: Centralise and Automate Insurance Tracking

Manually managing insurance documents across multiple suppliers can quickly become unmanageable.

Common issues include:

• Missed expiry dates
• Lost documents
• Inconsistent reviews

Using a centralised system allows you to:

• Track insurance compliance in real time
• Receive expiry alerts
• Standardise document reviews
• Reduce manual admin

Conclusion

Reviewing a supplier’s insurance certificate is not just a tick-box exercise, it’s a critical part of protecting your project from risk.

By following a structured review process, you can ensure suppliers are properly covered, compliant and fit to deliver work safely and reliably.

FAQs

What insurance should a supplier have in UK construction?

Most suppliers should have Employers’ Liability, Public Liability and (where relevant) Professional Indemnity insurance.

What happens if a supplier’s insurance expires during a project?

This creates a compliance gap and potential risk exposure. Suppliers should renew policies and provide updated certificates before expiry.

How do I know if insurance cover is sufficient?

Check the indemnity limits against your contract or framework requirements and ensure they align with the project risk level.

Can I accept a certificate without reviewing the full policy?

Certificates are useful, but if there are concerns, you should request the full policy wording or broker confirmation.

How often should insurance documents be reviewed?

At onboarding and regularly throughout the project, especially before expiry dates.
