Bank Guarantees in Commercial Leasing: The Issues Landlords Should Not Overlook

What is a bank guarantee?

A bank guarantee is a banking product issued by a bank in favour of the landlord. In simple terms, it is designed to give the landlord a level of security if the tenant defaults under the lease.

For many landlords, a bank guarantee is an attractive alternative to a cash bond because it can avoid the administration and cost associated with holding cash in trust. It can also reduce some of the complications that may arise if a tenant becomes insolvent. That is one of the reasons bank guarantees are often preferred in larger or more sophisticated commercial leasing arrangements.

Why landlords should take them seriously

The value of a bank guarantee does not come simply from having one on file. Its value comes from making sure it is in the right form, properly reviewed, carefully recorded and appropriately managed throughout the life of the tenancy.

A bank guarantee is not just routine paperwork. It is an important security instrument. If there is ever a need to rely on it, the detail of the document and the process around it can make a real difference. A weak process at the beginning can create unnecessary risk later.

Not all bank guarantees are the same

One of the most important things landlords should understand is that not all bank guarantees are created equal.

Details matter. The parties need to be correctly identified. The beneficiary needs to be correct. The wording needs to align with the lease and the circumstances in which the guarantee may later need to be relied upon. This is one reason lawyers often have a checklist or review process when dealing with bank guarantees. A proper review at the start can help identify issues before they turn into expensive problems later.

Expiry dates can create real risk

Expiry dates are one of the most common traps.

Many leases are structured on the basis that the bank guarantee should not expire, particularly where the tenant may remain in occupation beyond the original term. If a guarantee does contain an expiry date, there needs to be a reliable system for monitoring it and ensuring a replacement is obtained before it lapses. Without that, a landlord can find that security they thought was in place has quietly fallen away.

The source material you shared highlights this as a genuine issue and notes the importance of maintaining a register where expiry dates need to be tracked.

Assignment is often overlooked

Another issue landlords should pay close attention to is assignment.

A bank guarantee is usually issued in favour of a specific beneficiary and may not automatically transfer to a new owner if the property is sold. This can create a serious problem in a sale transaction if the incoming owner assumes the existing guarantee will simply continue to protect them. In many cases, replacement guarantees or other arrangements need to be dealt with before or at settlement.

This is one of the most overlooked risks with bank guarantees. People often assume the security moves neatly with the property, but in practice it may not.

Why the original document matters

A bank guarantee is not just an idea or a record on a file. It is a physical instrument of real importance.

The original document may be needed if the guarantee is ever called upon or if it is to be returned at the end of the lease. For that reason, the original should be treated with the same level of care as cash or another important legal document. The material you provided makes this point clearly, noting that it should be stored with the same seriousness as a will or title deed.

Who should hold the original?

There is no single answer that suits every landlord.

For some landlords, holding the original themselves will make complete sense because they have strong internal systems and secure storage. For others, a solicitor may be the natural choice. But not every landlord has the same circumstances. Some move often, some work remotely, and some do not have a reliable safe custody arrangement available to them. Increasingly, not every solicitor offers traditional safe custody services either.

The best option depends on the landlord’s own circumstances and what gives them the greatest confidence that the document will be secure, traceable and available when needed.

A good process matters

What matters most is that landlords make an informed decision and have a proper process around the document.

A good bank guarantee process is not just about collecting the original and putting it away. It is about asking the right questions from the outset. Is the guarantee in the right form? Does it expire? Is the beneficiary correct? Will it work if the property is sold? Is there a system for recording and tracking it? And is the original being held in a way that reflects its importance?

These are the kinds of issues that help protect a landlord’s position over the life of the lease.

Our view

At The Commercial Guys, we believe bank guarantees should be treated with the attention they deserve.

They are not just another piece of lease paperwork. They are an important part of a landlord’s protection, and the right process at the start can make a significant difference later. Whether the original is held by the landlord, a solicitor or another agreed solution, the key is that the decision is informed and the document is managed carefully.

Final thoughts

Landlords who understand the issues around validity, expiry, assignment and custody are in a far stronger position to protect their interests and avoid problems down the track.

A bank guarantee may look simple on the surface, but the detail matters. Giving it proper attention at the outset can help avoid unnecessary issues later and ensure that the security is there when it is needed most.
