What Is Covered Under New Build Warranty: The Basics
A new build warranty is a formal insurance-backed guarantee covering specified defects in a newly built or converted home, typically for ten years from completion. Most UK policies split that decade into two distinct periods: a defects period covering the first two years, and a structural period covering years three to ten. Understanding what is covered under new build warranty matters most in the first 24 months, when the builder is usually obliged to rectify a wider range of problems.
The warranty usually runs alongside, not instead of, your statutory rights under the Consumer Rights Act 2015, which you can read about via the Consumer Rights Act 2015. That distinction trips up a lot of buyers.
Surface Magic Repairs works with developers, site managers, and customer-care teams on cosmetic damage on new-build developments, so they understand which issues warranty providers accept and which they push back on.
Builder's Warranty vs Structural Warranty
A builder's warranty is the developer's own commitment to fix defects reported during the initial period. A structural warranty is the longer insurance policy, often provided by an approved scheme, that covers major structural failure after the builder's liability ends.
The two are not interchangeable. Your builder may handle a sticking door in month three; the warranty provider handles subsidence or roof failure in year eight.
What the NHBC and Similar Providers Cover
The NHBC is the best-known provider, but it is not the only one. Approved schemes include Premier Guarantee and LABC Warranty, all operating under standards recognised by lenders.
Broadly, these policies cover:
- Major structural defects affecting the stability of the home
- Defective materials or workmanship in the first two years
- Water ingress and damp-proofing failures
- Faulty foundations, walls, and load-bearing elements
- Roof structure and weatherproofing failures
What Is Typically Excluded from New Build Warranty
Exclusions catch people out far more often than inclusions. Most policies explicitly rule out general wear and tear, damage caused by poor maintenance, and anything the homeowner has altered or neglected.
Other common exclusions include:
- Damage from storms, floods, or subsidence linked to ground movement
- Condensation and its secondary effects
- Appliances, white goods, and boilers, which carry their own guarantees
- Landscaping, driveways, and boundary walls
- Damage you or a contractor cause after handover
The NHBC's guidance on what its Buildmark policy covers is worth reading before you assume a problem is claimable.
Cosmetic Damage and Wear and Tear
Cosmetic damage is the grey area that generates the most disputes. A chipped worktop, a scratched bath, or a scuffed door frame rarely qualifies as a structural defect, so the warranty provider will usually decline it.
That does not mean the damage is permanent. It means the fix sits with you, your builder's customer-care team, or a specialist repairer rather than the warranty insurer.
How Long Does New Build Warranty Last?
Ten years is the standard term across nearly all approved UK schemes. The cover is front-loaded: the first two years are the most comprehensive, and protection narrows considerably from year three onward.
| Period | Typical Cover | Who Handles It |
|---|---|---|
| Years 1-2 | Defects in materials and workmanship | Builder or developer |
| Years 3-10 | Major structural defects only | Warranty provider |
| Beyond 10 years | No warranty cover | Homeowner |
Timing matters. Report anything you find during the defects period in writing, because claims raised later are far harder to pursue.
The New Build Snagging List Explained
A snagging list is a documented schedule of defects, incomplete work, and cosmetic faults found after moving into a new property. It is your formal record for the builder, and it should be as specific as possible.
Walk each room methodically. Note chips, cracks, misaligned doors, poorly finished tiling, and damaged worktops with photographs and a short description of each item.
Send the completed list to the developer's customer-care team within the reporting window stated in your handover pack.
Cosmetic Defect Rectification for New Build Developments
Cosmetic defect rectification for new build developments is the process of repairing surface-level damage, such as chips, scratches, and scuffs, without removing or replacing the affected fixture. It is usually handled by the developer, a specialist contractor, or a repair firm working alongside the site team.
For housebuilders and contractors, this matters commercially: a full bathroom replacement delays handover, while a same-day repair keeps the plot moving.
Surface Magic Repairs works with developers, site managers, and customer-care teams on exactly this kind of work, repairing baths, worktops, tiles, doors, and uPVC frames in place. With more than 46,000 surfaces repaired in the last year, the team handles both single-plot snags and multi-unit programmes.
Why Cosmetic Defects Often Fall Outside Warranty
Warranty providers draw a hard line between structural failure and surface appearance. A chipped bath is not a structural defect, so the insurer will not pay, even though the chip is unsightly and the item is nearly new.
The practical answer is repair rather than replacement. Where the material and damage allow, a specialist can colour match and refinish the area so it blends with the surrounding surface, avoiding the cost and disruption of a full strip-out.
The New Build Warranty Claim Process Step by Step
The new build warranty claim process starts with written notice to the correct party: the builder during the first two years, the warranty provider after that. Keep every message, photograph, and response in one folder.
- Identify the defect and check whether it is structural or cosmetic.
- Notify the builder in writing during the defects period, with photos and dates.
- Allow a reasonable inspection window for the builder to assess and respond.
- Escalate to the warranty provider if the builder fails to act or disputes liability.
- Submit a formal claim with your policy number and supporting evidence.
- Await the provider's decision, which may include an independent survey.
- Arrange the remedy once approved, or pursue repair independently if declined.
When to Repair Rather Than Replace Under Warranty
Repair beats replacement in most cosmetic cases, and warranty providers rarely fund either. Suitability depends on the material, the extent of the damage, and the location of the affected surface.
A chipped bath, a burnt laminate worktop, a cracked shower tray, or a scratched uPVC frame can often be restored in place, with the repaired area colour matched to blend with the surrounding finish. Replacement means removal, disposal, and often retiling or redecorating as knock-on work.
Honest assessment matters here. Some damage is too extensive, or the material too compromised, for a durable repair, and a specialist should say so rather than patch it. Surface Magic Repairs assesses each job before booking and will advise when replacement is the better long-term option.
For developers and property managers, the wider benefit is waste reduction: fewer serviceable materials end up in landfill, and occupied buildings stay occupied.
New build warranty cover is narrower than most buyers expect, and cosmetic damage almost never qualifies. That leaves a gap between what the warranty pays for and what actually needs fixing. Surface Magic Repairs closes it, repairing chips, scratches, burns, and cracks in baths, worktops, tiles, doors, and uPVC in place, with colour and finish matched to the existing surface and no strip-out required. Send clear photographs of the damage, the complete item, and the surrounding area, along with your full address and postcode, to info@surfacemagicrepairs.com or call 0800 085 7773, and the team will confirm whether a repair is suitable and provide a quotation.
Frequently Asked Questions
What is the difference between a builder's warranty and a structural warranty?
A builder's warranty is provided directly by the housebuilder and usually covers defects in materials and workmanship for the first two years after completion. A structural warranty, often from a provider like NHBC, provides longer-term cover, typically 10 years, for major structural issues such as foundations, load-bearing walls and roof structure. The two often work together, with the builder handling early defects and the structural warranty covering serious problems that emerge later.
Does a new build warranty cover cosmetic damage like chips and scratches?
Most new build warranties exclude cosmetic damage such as chips, scratches, scuffs and minor dents, especially if they occur after you move in. Some builders will rectify cosmetic defects reported during the snagging period before handover, but once the warranty period progresses, these items are usually your responsibility. Specialist repair services can restore chipped baths, scratched worktops and damaged tiles without the cost and disruption of replacement.
How long does a new build warranty typically last?
In the UK, most new build warranties run for 10 years from the date of completion. The first two years are usually covered by the builder for a wide range of defects, including some cosmetic items. Years three to ten typically cover only major structural defects. Always check your specific warranty provider's terms, as cover levels and exclusions vary between providers.
What is the process for reporting defects under a new build warranty?
Start by documenting the defect with clear photographs and a written description. Report it to your builder or warranty provider through their formal claims process, usually within the notification period stated in your policy. Keep copies of all correspondence. For cosmetic defects that fall outside warranty, a specialist surface repair company can assess whether repair is possible, often providing a quotation from photographs before any visit.
