FAQs
What is construction supply chain due diligence?
It is the process of checking the financial, commercial, tax and compliance position of businesses within your construction supply chain before and during a contractual relationship.
Why is supply chain due diligence important?
It can help identify potential financial instability, tax issues, compliance problems and other risks before they affect your project or business. HMRC recommends ongoing supply-chain assurance rather than relying only on checks carried out at the start of a relationship.
What checks are included?
Depending on your requirements, we can review company information, directors, accounts, financial health, VAT, CIS, insurance, accreditations, contracts and subcontracting arrangements.
Can you check subcontractors?
Yes. We can support subcontractor due diligence, including reviewing company information, CIS status, financial information and relevant compliance records.
Can you check a supplier's financial health?
We can review available company accounts and financial information to help identify potential warning signs. Financial due diligence should be considered alongside other commercial and operational information.
Can you check CIS and VAT status?
Yes. We can review relevant CIS and VAT information and highlight inconsistencies or areas requiring further investigation.
Should supply chain due diligence be repeated?
Yes. HMRC recommends that businesses monitor and review their supply chains throughout contracts, particularly when there are changes to suppliers, workforce requirements, legislation or other identified risks.
Can you review multiple tiers of a supply chain?
Yes. Where relevant, we can help review subcontracting arrangements and supply-chain tiers to improve visibility beyond your immediate contractor or supplier.
Does due diligence guarantee that a supplier is risk-free?
No. Due diligence cannot eliminate all risk. Its purpose is to gather relevant information, identify warning signs and support proportionate risk management.
Can you help establish an ongoing supplier review process?
Yes. We can help structure ongoing supply chain monitoring, including the information to review and circumstances that should trigger a further assessment.
