Build Warranty: What It Means and How ABC+ Structural Warranties Protect Your Property

When you’re constructing or purchasing a new home, a build warranty or as we refer to it, a Structural Warranty is one of the most important safeguards you can arrange.
It protects your property against structural defects that might appear after completion.

At ABC+ Warranty, part of Architects Certificate, our policies are formally called Structural Building Warranties, and they’re backed by AXA Insurance UK plc.
These warranties are accepted by the majority of UK mortgage lenders and are designed to protect developers, homeowners, and self-builders alike.

What Is a Build Warranty?

A build warranty, or as we refer to it at ABC+, a Structural Building Warranty, is a specialist form of insurance that covers latent structural defects in a new build, conversion, or completed property.
While “build warranty” is a common industry term, ABC+ defines it specifically as a Structural Warranty that provides up to ten years of protection against structural faults caused by design, materials, or workmanship issues.

This warranty sits alongside our Professional Consultants Certificate (PCC) service, giving clients flexible options to satisfy lender requirements and manage construction risk effectively.

Who Needs a Structural Warranty?

Almost everyone involved in a construction project benefits from a structural warranty:

• Developers and builders – properties are easier to sell when warranty cover is in place.
• Self-builders – most lenders require an approved warranty or PCC to release funds.
• Homeowners – enjoy peace of mind and improved resale value.
• Mortgage lenders – rely on recognised warranty providers to mitigate post-completion risk.

ABC+ warranties are designed to meet these needs without unnecessary costs or memberships.

When Should You Arrange a Structural Warranty?

The ideal time to arrange a build warranty is before construction begins.

If your property is already complete, ABC+ offers Completed House Structural Warranties sometimes called retrospective cover to ensure protection can still be arranged even after completion.
