2-Year New Build Warranty: Your Complete Guide

Under NHBC Buildmark and most other UK new home warranties, the builder is responsible for putting right defects that breach the warranty standards and are reported within the first 2 years after legal completion, at no cost to you. This builder warranty (or defects) period is your primary protection as a new build buyer.

What Is Covered

  • +Workmanship defects
  • +Material failures not caused by you
  • +Items not meeting the specification you were sold
  • +Non-compliance with building regulations
  • +Damage caused by defects (e.g. damp from a failed seal)

What Is NOT Covered

  • -Normal shrinkage and movement (minor cracking)
  • -Damage you cause
  • -Items outside the builder scope
  • -Defects not formally reported before or at completion
  • -Cosmetic wear and tear

Critical: Document everything in writing. Verbal reports to your site manager do not create a formal record. Always email your defect list to the customer care team.

After Year 2

Years 3-10 of your NHBC Buildmark warranty cover structural defects only. Cosmetic and workmanship issues are no longer covered. This is why acting within the 2-year period is so important.

Frequently Asked Questions

What does the 2-year new build warranty cover?

The 2-year defects liability period covers workmanship defects, material failures, items not meeting the agreed specification, non-compliance with building regulations, and damage caused by defects (such as damp from a failed seal). Normal shrinkage, damage you cause, and cosmetic wear are not covered.

How do I make a claim under my 2-year new build warranty?

Report defects in writing to your builder's customer care team — email is acceptable and creates a paper trail. Include a clear description or photo of each defect. Keep copies of all correspondence. If the builder fails to respond, you can escalate to NHBC or the New Homes Ombudsman.

What is NOT covered by the 2-year warranty?

The 2-year warranty does not cover normal shrinkage and minor cracking, damage you cause yourself, items outside the builder's scope, defects not formally reported before the 2-year period expires, and general cosmetic wear and tear.

What happens after my 2-year warranty expires?

After 2 years, you move into the NHBC insurance period (years 3-10) which covers only major structural defects. Cosmetic and workmanship issues are no longer covered. This is why documenting and reporting all defects before the 2-year expiry is critical.

How long does a builder have to fix warranty defects?

There is no single fixed legal timescale, but NHBC guidance suggests defects should be rectified within a reasonable period. Urgent or safety-critical defects (such as heating failures in winter) should be addressed within days. Non-urgent defects are typically expected to be fixed within 30-60 days.
