Property Defects & Warranties


Overview

Buying a property - especially a new build - can come with unexpected defects. From minor snagging issues to serious structural problems, UK homeowners have a range of legal remedies available. This guide covers new-build warranty claims, developer liability, and enforcement options for defective properties.

Key Legislation and Protections

  • Defective Premises Act 1972, Section 1 - A duty on those who provide dwellings to ensure the work is done in a professional manner, with proper materials, so the dwelling is fit for habitation. Extended to 30 years for claims arising from the Building Safety Act 2022.

  • Building Safety Act 2022 - Introduced sweeping reforms for building safety, including retrospective liability for developers of defective buildings

  • Consumer Rights Act 2015, Part 1 - If you contract directly with a developer for a new build, the property must be of satisfactory quality (Section 9) and fit for purpose (Section 10)

  • Supply of Goods and Services Act 1982, Section 13 - Work must be carried out with reasonable care and skill (applies to builders and tradespeople)

  • Building Regulations 2010 - Minimum standards for construction; breach may give rise to civil claims
  • New-Build Warranty Schemes

    NHBC Buildmark


    The most common warranty for new-build homes. It provides:
  • Years 1-2 (Builder Warranty Period): The builder must fix defects that breach NHBC standards. If they refuse, NHBC can intervene via its Resolution Service.

  • Years 3-10 (Insurance Period): NHBC covers physical damage caused by defects in specified structural elements (foundations, load-bearing walls, roof structure, etc.)

  • Claims must relate to defects that breach NHBC Technical Requirements (Standards Chapters 1-10)
  • LABC Warranty / Premier Guarantee / ICW


    Alternative warranty providers with similar structures. Always check the specific terms of your warranty, as coverage varies.

    Important Warranty Limitations


  • Warranties typically exclude cosmetic defects after year 2

  • Snagging items (minor defects) should be reported as early as possible, ideally before or at completion

  • The warranty does not replace your legal rights against the developer
  • Step-by-Step: Pursuing a Property Defect Claim

    Step 1: Document Everything


  • Photograph and video all defects with dates

  • Keep a written log of when defects appeared and any impact on habitability

  • Obtain independent reports (structural engineer, damp specialist, surveyor) where needed
  • Step 2: Report to the Developer


    Write formally to the developer (or builder), listing each defect and referencing:
  • Your warranty obligations (e.g., NHBC Standards)

  • Consumer Rights Act 2015 (if you bought directly from the developer)

  • Defective Premises Act 1972, Section 1

  • A reasonable deadline for response (typically 14-28 days)
  • Step 3: Escalate to Your Warranty Provider


    If the developer does not resolve the issues within the builder warranty period:
  • Submit a formal claim to your warranty provider (e.g., NHBC Resolution Service)

  • Provide your evidence pack including independent reports

  • The warranty provider will assess and may instruct their own inspection
  • Step 4: Use the New Homes Ombudsman


    The New Homes Quality Board operates a code of practice and an ombudsman service for new-build complaints. If your developer is a registered member, you can escalate unresolved complaints to this free service.

    Step 5: Consider Legal Action


    If other routes fail:
  • Letter Before Action referencing the Pre-Action Protocol for Construction and Engineering Disputes

  • County Court or Technology and Construction Court (TCC) depending on claim value and complexity

  • Claims under the Defective Premises Act 1972 now have a 30-year limitation period (thanks to the Building Safety Act 2022, Section 135) for dwellings completed after 28 June 1992
  • Key Points

  • You do not need to use the warranty before suing the developer - These are separate legal rights

  • Limitation periods vary: 6 years for breach of contract (Limitation Act 1980, Section 5), 6 years for negligence (or 3 years from date of knowledge under Section 14A), and now up to 30 years under the Defective Premises Act 1972 as amended

  • Consequential losses are claimable - Including alternative accommodation costs, loss of rental income, and diminution in value

  • Building control sign-off does not mean no defects exist - A completion certificate does not prevent a claim

  • Shared owners and leaseholders also have rights under the Building Safety Act 2022
