New Build Warranties: A Guide for Home Buyers

Purchasing a new build home is an exciting venture, filled with the anticipation of moving into a freshly constructed property with all the latest designs and modern conveniences. However, the purchase of a newly built home also brings with it specific considerations, particularly regarding the structural integrity and quality of construction. This is where new build warranties, or structural warranties, come into play, offering crucial protection to home buyers in the UK.

What Are New Build Warranties?

New build warranties serve as insurance policies designed to provide peace of mind to individuals purchasing newly constructed homes. These policies are fundamentally geared towards protecting homeowners from potential defects in both the structure and the craftsmanship of the building. Generally spanning a duration of up to 10 years, these warranties are tailored to address significant structural issues that could impact the home’s safety and overall usability, ensuring that any such problems are rectified without additional costs to the homeowner.

In the UK, the market for new build warranties is predominantly occupied by a few major players, each offering distinct levels of coverage tailored to a variety of needs. The NHBC Buildmark warranty stands out as the most prevalent, safeguarding over 80% of new homes across the country with a robust decade-long protection against structural defects. Alongside NHBC, other notable providers include Premier Guarantee and LABC Warranty, each bringing their unique coverage options and customer service offerings to the table. These providers differ not only in the breadth and specifics of their coverage but also in how they handle customer interactions and resolve claims, reflecting their individual approaches to ensuring homeowner satisfaction and security.

Making a Claim

If a defect arises in a newly constructed home, initiating a claim under a new build warranty is a process that, while straightforward, demands careful attention and prompt action. Homeowners are required to observe any potential issues and quickly report these concerns to their warranty provider, clearly detailing the nature of the defect to ensure accurate assessment. The warranty provider will then undertake a thorough evaluation of the claim to ascertain whether the reported defect is indeed covered under the terms of the warranty.

Once a claim is validated and approved, the warranty provider takes on the responsibility of coordinating and financing all necessary repairs. This ensures that the homeowner is shielded from any direct financial burdens that may arise from foundational or significant structural repairs. This part of the process is critical, as it not only fixes the immediate issue but also helps in maintaining the integrity and value of the home over time, reinforcing the homeowner’s investment and the home’s longevity.

What is Covered?

New build warranties are primarily designed to provide coverage for significant structural defects that directly impact the integrity and safety of the home. This includes major issues such as foundational flaws, which can compromise the entire structure, and problems with the roof structure, which are crucial for the home’s weather resistance and overall durability. These warranties also address other critical construction faults that can lead to problems such as water ingress, which can cause further damage to the property, or structural instability that might pose safety risks to occupants.

Beyond just the fundamental structure, these warranties often extend to include various defects in the home’s essential systems caused by construction errors. This can encompass issues within the electrical systems, which are vital for the home’s functionality, as well as defects in the plumbing and heating systems, which are crucial for a comfortable living environment. By covering such a broad range of potential problems, new build warranties ensure that homeowners can enjoy their new properties with confidence, knowing that they are protected against a wide array of construction-related issues.

Comparing Warranties

When selecting a new build home, one of the crucial steps is to diligently compare the warranties offered by different developers. This comparison should not be taken lightly, as the chosen warranty can significantly impact the long-term satisfaction and security of your investment. Key factors to consider in this evaluation include the extent of the coverage provided by the warranty, which details what specific defects and issues are included. Additionally, the duration of the warranty is crucial, as it determines how long your home will be protected under the terms of the warranty.

Equally important is the reputation of the warranty provider. A provider with a strong reputation is likely to handle claims more efficiently and supportively, enhancing your experience as a homeowner. A more comprehensive and longer-lasting warranty can also signal a developer’s confidence in the quality of their construction and their commitment to customer satisfaction. Therefore, by thoroughly comparing these aspects—coverage, duration, and provider reputation—homebuyers can make a more informed decision, ensuring they choose a warranty that offers the best protection and peace of mind for their new home.


While new build warranties offer comprehensive protections that are invaluable for new homeowners, it is crucial to recognize that they are not all-encompassing. These warranties typically exclude general wear and tear and cosmetic damage, both of which are considered inevitable parts of the normal aging process of any residential property. Such exclusions ensure that the warranties focus on more serious structural and systemic issues that could impact the home’s safety and usability.

New build warranties do not cover issues that arise from homeowner modifications or poor maintenance. This emphasises the importance of proper home care and adherence to maintenance guidelines. Modifications made without professional guidance or failure to maintain critical systems like plumbing and heating can lead to problems that fall outside the scope of the warranty. This underscores the homeowner’s responsibility to maintain their property to ensure ongoing coverage under the terms of their warranty. Understanding these limitations is key to fully appreciating what new build warranties do and do not provide, allowing homeowners to take proactive steps in safeguarding their home’s condition and value.


New build warranties are indispensable for anyone purchasing a newly constructed home in the UK. They not only offer protection from potential structural issues but also ensure that any such problems are rectified at no additional cost to the homeowner. Understanding the details of these warranties, including what is covered and how to effectively make a claim, is crucial. By doing so, homeowners can secure not just a house, but a well-protected home.

By approaching the purchase of a new build with a thorough understanding of what these warranties entail and how they can safeguard your investment, you ensure that your new home remains a source of joy and security for many years. Always take the time to review and compare different warranty offerings and choose the one that best fits your needs, for it is more than just a policy – it is a fundamental part of your home’s longevity and your peace of mind.
