Self-Build Warranty Insurance

Self-Build Warranty

A self-build warranty is first party insurance that provides protection to individuals who are constructing their own homes or managing a self-build project.

This warranty offers coverage against structural defects and ensures that the completed self-build project complies with building regulation standards. It is designed to give self-builders peace of mind and financial protection in case any issues arise after the construction is completed.

In most cases, it is a requirement of the policy for the self-builder to live in the property for 12 months after practical completion before selling – Otherwise they may incur additional premium costs, should they wish to sell before that point in time.

Additionally, should there be a need to refinance or sell the property during the 10-year period after practical completion, the self-build warranty will offer the bank/lenders involved sufficient comfort to deploy funds.

While a Professional Consultants Certificate is often seen as a popular alternative to a self-build warranty, there are a number of considerations to be taken into account before opting for a non-insurance-based solution that may not actually protect self-builders should insurance be called upon.

What is a self-build warranty?

A self-build warranty is a 10 year insurance policy specifically designed for individuals undertaking self-build or custom-build projects to protect against any substantial defects that might occur post-construction in homes built or renovations.

It’s worth noting that this type of building warranty isn’t just another form of building insurance; they are distinctly different.

What are the benefits of a self-build warranty?

A self-build warranty provides three primary benefits: financial security, peace of mind, and making future sales easier.

Financial Protection 

Without a self build warranty, the responsibility for financing rectification work falls solely on the homeowner’s shoulders. A structural warranty provides cover against design deficiencies and faulty installation.

Peace of Mind

Beyond monetary matters, the self build warranty gives the beneficiary of the policy peace of mind that should there be any structural issues that arise after practical completion, they have first party insurance in place.

Selling in the Future

While not legally mandated, a structural warranty is widely regarded as an essential requirement for purchasing a new build property built in the last 10 years. By having a structural warranty in place, homeowners and potential buyers gain peace of mind, knowing that any issues will be addressed, bolstering the property’s marketability and protecting its long-term value.

Who needs a self-build warranty?

For individuals embarking on a self-build project with the intention of residing in the finished property, obtaining self-build structural warranty cover is essential. This specialised insurance provides essential protection against potential structural issues that may arise during or after construction.

By proactively acquiring Self-Build structural cover or a structural warranty, you not only instil confidence in lenders but also provides you with the necessary peace of mind throughout the self-build journey.

What does a self-build warranty cover?

A self-build warranty offers comprehensive coverage for the costs of a complete or partial rebuilding and rectification due to structural defects. While some defects may not be immediately evident upon practical completion, they can emerge years later. The insurers will indemnify the policyholder against claims discovered and notified to the underwriter during the period of insurance in respect of:

  • Complete or partial rebuilding or rectifying work for the unit affected by significant damage caused by defects in design, workmanship, or materials. The insurers’ liability is limited to the reasonable cost of rebuilding each housing unit according to its original specifications.
  • Rectifying any defect in the newly constructed drainage system related to the housing unit, for which the policyholder bears responsibility. 
  • Repairing, replacing, or rectifying any part of the waterproof envelope within the housing unit due to water ingress resulting from defects in design, workmanship, materials, or components of the waterproofing elements. The insurers will cover the reasonable and essential costs incurred for these necessary repairs.

With this comprehensive coverage, the policyholder can rest assured knowing that the insurers will provide financial support for addressing these specific issues related to the housing unit.

Typically, many mortgage lenders require a 10-year structural warranty before agreeing to finance any custom or self-build project. This requirement safeguards their financial interests by ensuring that potential costs related to construction defects will be covered.
