Guarantees and bonds are widely used on construction and engineering projects to provide additional security where there are concerns around performance, payment, completion or the financial standing of a contracting party. They can provide reassurance to employers, funders and other stakeholders by offering an additional form of protection alongside the underlying construction contract.

DTM Legal advises developers, employers, contractors, subcontractors, consultants and other project stakeholders on the preparation, review and negotiation of construction guarantees and bonds. This includes parent company guarantees, performance bonds and other forms of security required as part of the contractual arrangements for a project.

Our Construction & Engineering team helps clients understand the protection being offered, the circumstances in which the security may be relied upon and how the document interacts with the wider contract structure. We focus on ensuring guarantees and bonds reflect the intended commercial position and do not create unnecessary uncertainty or unintended risk.

Why Instruct DTM Legal?

Guarantees and bonds can provide valuable additional protection on construction projects, but their effectiveness depends on the wording of the document and how it relates to the underlying contractual arrangements. Unclear or inconsistent provisions can create uncertainty about the obligations being secured or the circumstances in which the security can be relied upon.

Our Construction & Engineering solicitors provide practical advice focused on the commercial purpose of the security arrangement. We consider the risks the guarantee or bond is intended to address, the protection required by the beneficiary and the obligations being accepted by the party providing the security.

We also review guarantees and bonds in the context of the wider project documentation. This can include considering how they interact with building contracts, subcontracts, professional appointments, collateral warranties, insurance arrangements and other contractual protections.

Where issues arise during a live project, timely advice can be particularly important. We can help clients understand the wording of the relevant security document, assess the contractual position and consider the practical steps available while taking account of the wider commercial relationship between the parties.

We provide:

  • Clear and commercially focused advice on construction guarantees and bonds.
  • Support with drafting, reviewing and negotiating security documents.
  • Practical advice on the scope and operation of proposed security.
  • Careful consideration of liability, trigger events and duration.
  • Coordination with the wider suite of construction contracts and project documents.
  • Responsive advice where guarantees or bonds become relevant during a live project.

Frequently Asked Questions

Commonly asked questions regarding guarantees and bonds for a construction project.

Guarantees and bonds are used to provide an additional layer of contractual protection where a party wants greater security against risks such as non-performance, payment default, insolvency or problems with project completion.

The appropriate form of security will depend on the project, the parties involved and the particular risk that needs to be addressed. The document should therefore be considered alongside the underlying construction contract rather than treated as a standalone requirement.

A parent company guarantee and a performance bond are both used to provide additional project security, but they involve different arrangements.

A parent company guarantee involves a parent company supporting obligations owed by another company within its group. A performance bond is a separate form of security intended to provide protection in relation to the performance of contractual obligations.

The protection provided in either case will depend on the specific wording of the document, including the obligations covered, any limits on liability and the circumstances in which it can be relied upon.

The key practical consideration is the basis on which the bond can be called. Different wording can significantly affect what a beneficiary must establish before payment can be required.

It is therefore important for both the party requiring the bond and the party arranging it to understand the proposed trigger provisions and the practical consequences of the wording before the document is agreed.

The requirement for a guarantee or bond should ideally be identified when the main construction contracts are being negotiated. This allows the type of security, required terms and timing for delivery to be agreed before the project progresses.

Leaving security arrangements until a later stage can create delays where a funder, employer or other stakeholder requires the document before works commence, funding is released or another project milestone is reached.

The proposed document should be reviewed alongside the underlying construction contract to understand exactly what obligations are being secured.

Particular attention should be given to the scope of the security, the circumstances in which it can be relied upon, liability limits, exclusions, expiry provisions and any requirements imposed by funders or other stakeholders. These terms should reflect the commercial arrangement and the level of risk the party providing the security has agreed to accept.
