Insolvency is one of the biggest risks in the construction industry. What might first appear to be the perfect project can quickly spiral into the perfect storm. When a main contractor suddenly goes bust, the beneficiary of a project can be left stranded, with no direct contractual link to the subcontractors or consultants delivering the work.
This is where collateral warranties step in.
What Is a Collateral Warranty?
According to Hill Dickinson, “a collateral warranty is a contract under which a party involved in the works warrants to a third-party beneficiary that it has fulfilled its obligations under its building contract, subcontract, or professional appointment.“
Put simply, a collateral warranty acts as a bridge. It creates a legal link between a party in the construction chain (such as a subcontractor or consultant) and a third party who has an interest in the project but no direct contractual relationship (such as a client, tenant, or funder).
Why Are They Important?
Let’s look at a typical project setup:
- A client hires a main contractor.
- The main contractor then hires subcontractors.
If the main contractor becomes insolvent, the client might want to hold the subcontractor accountable for their work. Without a direct contractual link, this becomes extremely difficult. A collateral warranty gives the client that legal connection, allowing them to pursue claims or enforce obligations if necessary.
And it’s not just about clients and subcontractors. Collateral warranties can be used wherever there’s a gap in contractual relationships. For instance:
- Funders may want warranties from contractors or consultants to safeguard their investment.
- Tenants may seek warranties from contractors to cover defects.
- Purchasers may require them before acquiring a development.
What Does a Collateral Warranty Look Like?
Collateral warranties are usually short documents, often fewer than 10 pages, and draft copies are normally included within the main contract. They set out the obligations owed to the third party and ensure accountability even if another party in the chain fails.
The Contract (Rights of Third Parties) Act 1999
Before 1999, collateral warranties were essentially the only way to give third parties enforceable rights. This changed with the introduction of the Contract (Rights of Third Parties) Act 1999, which states:
- A third party can enforce a contract term if:
- The contract expressly provides that they may, or
- The term appears to confer a benefit on them.
- However, the contract can opt out, stating that the parties did not intend for third parties to enforce any terms.
This opt-out clause is common in construction contracts, meaning collateral warranties remain a key tool in practice.
Final Thoughts
Collateral warranties may look like simple pieces of paperwork, but they play a crucial role in protecting stakeholders when insolvency or disputes threaten a project. They provide certainty, accountability, and protection in an industry where risk is always close at hand.
For anyone involved in construction, whether client, funder, contractor, or consultant, understanding and properly managing collateral warranties is essential.
