Discovering a problem in your new build home can be unsettling. Whether it is cracking, damp, roof issues or something more serious, the immediate question is usually the same: how do I make a new build warranty claim?
The answer depends on one crucial detail: how old your property is. The new build warranty claim process works differently in years 1–2 compared to years 3–10. Understanding that distinction before taking action will save time, reduce stress and protect your position.
Understanding Your Warranty Before You Claim
Before starting a new build warranty claim, confirm which stage of cover applies to your property.
A standard new home warranty is split into two periods:
Years 1–2: The builder is responsible for fixing defects that breach the warranty provider’s technical standards.
Years 3–10: The warranty insurer covers major structural defects.
This distinction is the most important structural point in the entire new build warranty claim process. Contacting the wrong party at the outset is one of the most common causes of delay.
If you completed less than two years ago, you contact your builder first.
If you completed more than two years ago, you usually contact the warranty provider directly.
What Defects Are Covered by a New Build Warranty Claim?
Not every issue in a new property is covered.
In general:
During Years 1–2
The builder must rectify defects that result from poor workmanship or failure to meet the provider’s technical standards. This may include:
- Poorly fitted components
- Incorrect installation
- Faulty finishes that breach standards
Minor cosmetic snags are normally handled during the snagging process rather than through formal warranty claims.
During Years 3–10
The policy narrows to serious structural defects, such as:
- Foundation failure
- Structural wall movement
- Roof structural defects
- Significant structural water ingress
Understanding what a structural warranty covers is essential before beginning the claim process.
If you are asking whether you can claim for damp or water ingress, the answer depends on the cause. Damp resulting from structural failure may qualify. Damp caused by condensation, ventilation issues or maintenance is usually excluded.
Step 1 – Report the Defect to Your Builder (Years 1–2)
If you are within the first two years after completion, your first action must be to notify the builder in writing.
Put everything in writing
Your written notice should include:
- A clear description of the issue
- The date it was first noticed
- Photographs
- Any relevant background information
Written records from day one are critical. Avoid relying on verbal conversations, informal site visits or text messages alone. Email is generally best as it creates a clear timestamped record.
Set a reasonable response deadline
What is reasonable depends on the severity of the issue.
For urgent safety matters, a few days may be appropriate.
For non-urgent defects, two to four weeks is usually considered reasonable.
Be clear, factual and professional in your communication. If the builder fails to respond or refuses to act, the next step is escalation.
Guidance on what homeowners can do if a builder is not honouring a 1 year warranty explains the escalation pathway.
Developers should note that prompt written responses at this stage often prevent formal new build warranty claims later.
Step 2 – Escalate to the Warranty Provider if the Builder Fails to Act
If the builder does not respond within a reasonable timeframe, you can escalate your new build warranty claim to the warranty provider.
Each provider has its own submission process. NHBC, LABC and Build-Zone operate structured online claim portals or formal notification procedures.
What to include when escalating
Prepare:
- Your warranty certificate number
- Completion date
- Copies of your written communication with the builder
- Photographs and supporting evidence
- Any inspection or survey reports
The warranty provider will typically:
- Review your documentation
- Contact the builder
- Arrange an inspection if required
In years 1–2, the provider’s role is often to enforce the builder’s obligations rather than pay directly for works.
Claiming on Structural Insurance (Years 3–10)
After year two, the new build warranty claim process changes. Claims are made directly to the insurer.
This stage applies to serious structural defects only.
Evidence requirements
In years 3–10, insurers often require stronger technical evidence. This may include:
- A structural engineer’s report
- An independent surveyor’s assessment
- Detailed photographic evidence
The insurer will assess whether the defect:
- Affects structural integrity
- Results from design, materials or workmanship
- Falls within policy terms
Cosmetic cracking, minor shrinkage or wear and tear will not usually qualify.
What Documentation Do You Need?
Whether you are in years 1–2 or years 3–10, documentation is central to a successful new build warranty claim.
You should gather:
- Your original warranty certificate
- Purchase completion documents
- A written description of the issue
- A timeline of when it developed
- Photographs
- Copies of correspondence with the builder
- Any professional reports
Organised evidence strengthens your position.
Many disputes arise because homeowners delay reporting issues or rely on informal conversations. Our article on top five common warranty claim mistakes and how to avoid them highlights common pitfalls that can weaken claims.
How Long Does a New Build Warranty Claim Take?
There is no fixed timeline. The length of a new build warranty claim depends on:
- Whether it is a builder-stage or insurer-stage claim
- The complexity of the defect
- The need for inspections or reports
- The responsiveness of the parties involved
Builder-stage defects may resolve within weeks. Structural insurance claims can take several months, particularly if expert assessments are required.
You can reduce delays by:
- Reporting promptly
- Providing complete documentation
- Responding quickly to requests for access
What Is the Time Limit for Making a New Build Warranty Claim?
Claims must be made within the warranty period.
If your policy runs for 10 years, notification must occur before the expiry date. Discovering a defect late in year ten does not automatically extend the policy.
If you suspect a defect, report it immediately. Early notification protects your rights even if investigation continues after expiry.
What Happens if the Warranty Provider Rejects Your Claim?
If your new build warranty claim is rejected, do not assume the matter is closed.
Review the rejection carefully
Providers will explain their reasoning. Common grounds include:
- The issue is cosmetic rather than structural
- The defect falls outside policy scope
- The cause relates to maintenance or homeowner alteration
Use the internal complaints process
All warranty providers operate formal complaints procedures. Submit additional evidence if available and ask for a review.
Refer to the Financial Ombudsman Service
If you remain dissatisfied after exhausting the provider’s internal process, you can refer the matter to the Financial Ombudsman Service. This independent body reviews disputes involving insurance-backed products.
The Ombudsman can require insurers to reconsider decisions if they have acted unfairly or outside policy terms.
Developers should be aware that escalation to the Ombudsman can have reputational and regulatory implications. Clear communication and documented compliance reduce that risk.
Guidance for Developers Handling Claims
Although this guide focuses on buyer intent, developers play a key role in the new build warranty claim process.
Best practice includes:
- Keeping detailed build records
- Retaining inspection certificates
- Responding promptly to defect notifications
- Documenting all communications
- Escalating appropriately when insurer input is required
Proactive handling of early-stage defects prevents formal disputes and protects long-term brand value.
Final Practical Checklist
If you are a homeowner:
- Confirm whether you are in years 1–2 or years 3–10.
- Put your complaint in writing.
- Keep clear records from day one.
- Escalate formally if necessary.
- Seek professional advice for structural concerns.
If you are a developer:
- Acknowledge defects promptly.
- Maintain written documentation.
- Follow the provider’s technical standards.
- Cooperate fully during inspections.
The structure is straightforward. Years 1–2 the builder is liable. Years 3–10 the insurer covers structural defects. Written records are fundamental throughout the new build warranty claim process.
