In construction, ensuring that the completed work is of high quality and free from defects is critical. However, despite the best efforts of contractors and developers, defects can sometimes arise after a project is completed. This is where the defects notice comes into play, a vital mechanism in construction contracts that helps both clients and contractors address issues that arise after practical completion.
At Blackstone Solicitors, we frequently advise construction companies across England and Wales on legal matters related to construction contracts, including defects notices. In this article, we’ll explore what a defects notice is, how it functions within construction projects, and what construction companies need to know to manage this process effectively.

What is a Defects Notice?
A defects notice is a formal notification issued by the client (or their representative) to the contractor, specifying defects that have been identified in the construction works after practical completion. These defects can relate to poor workmanship, non-compliance with design specifications, or the use of substandard materials. A defects notice initiates the process by which the contractor is required to rectify the defects within an agreed period, usually during the Defects Liability Period (DLP).
The purpose of issuing a defects notice is to ensure that any problems with the building are addressed without incurring additional costs to the client. It is a contractual safeguard for the client, while also providing the contractor with a structured process to resolve issues.
Understanding the Defects Liability Period
Most construction contracts include a Defects Liability Period, typically ranging from six to twelve months, though this can vary depending on the contract. During this period, the contractor remains responsible for fixing any defects that are discovered and notified by the client.
A defects notice is an essential part of the process, as it formally alerts the contractor to any faults that need addressing. The DLP begins after practical completion, when the building is considered ready for use, though minor issues may still exist. Contractors should be prepared to return to the site to correct these issues as they arise.
Once the defects are rectified, and after the DLP ends, a final inspection is typically carried out, after which the client will issue a certificate confirming that all necessary work has been completed. This final stage often results in the release of any remaining retention funds held by the client.
The Role of the Contractor in Defects Notice Management
For contractors, effectively managing defects notices is a critical part of ensuring client satisfaction and maintaining professional relationships. Here’s what contractors need to know:
- Responding Promptly to a Defects Notice
Upon receiving a defects notice, the contractor is obligated to address the issues within the timeframe stipulated in the contract. Delays in responding or failing to rectify defects promptly can damage the contractor’s reputation and may lead to financial penalties or legal action.
Defects notices should always be treated as a priority, and contractors should have systems in place to ensure swift responses to any such notices during the Defects Liability Period. Efficient handling of defects can help maintain client trust and minimise the risk of disputes.
- Determining the Nature of Defects
It’s important for contractors to carefully assess the defects that have been highlighted. A defect can range from cosmetic issues, such as poor finishing, to more serious structural problems that affect the building’s safety or functionality.
Defects are typically classified into two categories:
- Patent Defects: These are visible or obvious defects that can be easily identified during or immediately after the completion of the project.
- Latent Defects: These are defects that are not immediately visible and may only become apparent months or even years after practical completion.
While the Defects Liability Period usually covers patent defects, latent defects might fall outside the DLP and could give rise to further claims, potentially under a separate latent defects warranty or insurance.
- Rectifying Defects at No Additional Cost
The contractor is usually required to rectify defects at their own expense, provided the defect arises from their work, materials, or failure to meet the contract’s specifications. If the defect is caused by the client or other external factors, such as poor maintenance or external damage, the contractor may not be liable for the costs.
Contractors should ensure that they thoroughly understand the scope of their liability under the contract and work with the client to clearly define what constitutes a defect before construction begins. This can help avoid confusion and disputes later on.
- Maintaining Documentation
It is crucial for contractors to maintain detailed records throughout the construction process. This includes documentation of work completed, materials used, and any issues encountered. Keeping a clear paper trail will help contractors respond to defects notices efficiently and can provide valuable evidence if there is a dispute over the nature or cause of the defects.
During the Defects Liability Period, any repairs or rectification work should also be thoroughly documented, including before-and-after photographs and written reports. This ensures transparency and accountability, which is vital for maintaining professional relationships and avoiding legal conflicts.
Common Causes of Defects in Construction
Understanding the common causes of defects can help contractors proactively manage their projects and reduce the likelihood of defects notices being issued. Some typical causes include:
- Poor Workmanship: Mistakes or shortcuts during the construction process, such as inadequate joint sealing or uneven flooring, can lead to defects that may only become apparent after the building is in use.
- Substandard Materials: Using materials that do not meet the required specifications or are of inferior quality can result in defects, especially if these materials deteriorate quickly or fail to perform as expected.
- Non-Compliance with Design Specifications: If the construction does not follow the agreed-upon design specifications, the final structure may have defects related to functionality, durability, or aesthetics.
- Environmental Factors: Sometimes, external conditions such as extreme weather, moisture, or temperature changes can lead to defects, especially if the building materials or techniques used are not suitable for the local environment.
Preventing Disputes Over Defects Notices
Despite a contractor’s best efforts, disputes can arise over defects notices, particularly if there is disagreement about the nature of the defects or the timeline for rectification. Here are some ways contractors can reduce the risk of disputes:
- Clear Contractual Terms
One of the most effective ways to prevent disputes is by ensuring that the contract clearly outlines the procedures for dealing with defects. This includes specifying what constitutes a defect, the length of the Defects Liability Period, and how defects notices should be issued and handled.
At Blackstone Solicitors, we advise construction companies on drafting and reviewing contracts to ensure that these provisions are clear and enforceable, protecting both parties from misunderstandings and legal issues down the line.
- Regular Communication with the Client
Maintaining open and regular communication with the client throughout the project and during the DLP is key to preventing disputes. If the client is kept informed of progress and potential issues, it becomes easier to address any defects that arise and manage their expectations.
In cases where the client has identified a defect, engaging in constructive dialogue to understand their concerns and work collaboratively to resolve the issue can help maintain a positive relationship and reduce the likelihood of formal disputes.
- Engaging Legal Support When Necessary
If a dispute over defects notices escalates, contractors may need to seek legal advice. Whether it’s a disagreement over liability for a defect or disputes about the adequacy of rectification work, having legal support ensures that contractors can navigate these challenges professionally and minimise the impact on the project’s success.
