Building Warranty Insurance 

Building Warranties UK

Protect Your Property Investment with a 10-Year Structural Warranty

A Building Warranty, also known as a Structural Warranty or Latent Defects Insurance, is essential protection for property owners, self-builders, developers and contractors. Designed to safeguard against structural defects that may emerge after construction is completed, these policies provide long-term peace of mind and financial security.

Most UK mortgage lenders require a valid 10-Year Building Warranty before approving mortgages or refinancing applications. Whether you are constructing a new home, undertaking a barn conversion, renovating a property, or developing a commercial project, securing the right warranty is a vital part of the build process.

What Is Covered by Building Warranty Insurance?

A Structural Building Warranty protects against hidden defects in design, workmanship and materials that may affect the structural integrity or habitability of a building.

Typical cover includes:

  • Foundation defects
  • Structural failures of load-bearing elements
  • Roof and wall structural defects
  • Waterproofing failures
  • Latent defects affecting the safety or habitability of the property

Most policies provide protection for 10 years from Building Control sign-off, although certain commercial and social housing developments may qualify for cover of up to 12 years.

Why Latent Defects Insurance Matters

Structural issues can remain hidden for years before becoming apparent. A Building Warranty ensures that costly repairs resulting from covered defects are addressed without placing a significant financial burden on property owners.

Importantly, Building Warranties are linked to the property rather than the owner. If the property is sold during the warranty period, the remaining cover transfers to the new owner, helping improve marketability and buyer confidence.
