What Is the Difference Between Site Insurance, Building Control and a Structural Warranty?

Site Insurance protects a self build against specified risks during construction. Building Control checks whether work complies with Building Regulations. A Structural Warranty provides insurance protection against qualifying defects after completion. They perform different roles, and none replaces appropriate health and safety management on site.

What Does Site Insurance Protect?

Site Insurance is designed for the construction phase of the project. Depending on the policy and cover selected, it can protect the new works, building materials, temporary works and an existing structure where applicable.

It can also include specified liability protection and optional cover for items such as plant, tools, equipment or temporary buildings. In simple terms, Site Insurance is concerned with financial risks that can arise while the home is being built.

What Does Building Control Do?

Building Control has a different purpose. It considers whether building work complies with the requirements of the Building Regulations. These regulations cover areas including structure, fire safety, ventilation and energy performance.

Building Control approval is therefore an important part of the construction process, but it is not an insurance policy. A completion certificate does not provide financial cover if an insured structural defect emerges later.

What Does a Structural Warranty Do?

A Structural Warranty provides specified insurance protection after the home has been completed. Self-Build Zone offers a 10 Year Structural Warranty for self build projects, subject to the policy terms and acceptance criteria.

The warranty can respond to qualifying defects relating to specified aspects of design, workmanship, materials and components of the new works. Because it is an insurance product, its purpose is different from the regulatory role performed by Building Control.

Where Does Health and Safety Fit?

Health and safety is another separate area. Site Insurance, Building Control and a Structural Warranty do not remove the need for construction risks to be properly managed.

Under CDM 2015, contractors, principal contractors, designers and other dutyholders have defined responsibilities. On a domestic project, relevant client duties will normally pass to the contractor or principal contractor. Safe access, site security, welfare and management of construction hazards still need proper attention throughout the build.

Which Protection Applies at Each Stage?

Do I need both Site Insurance and a Structural Warranty?

They address different risks and different stages. Site Insurance principally protects during construction, while a Structural Warranty provides specified protection after completion.

Does Building Control approval replace a Structural Warranty?

No. Building Control assesses compliance with Building Regulations. A Structural Warranty is an insurance product with its own technical and policy requirements.

Does insurance replace health and safety responsibilities?

No. Insurance can provide financial protection following specified events, but it does not replace safe working practices or the legal duties of those managing construction work.

The simplest way to think about these protections is that they work alongside one another. Site Insurance helps protect the project while it is being built. Building Control addresses regulatory compliance. A Structural Warranty provides long-term insurance protection after completion. Self-Build Zone can provide both specialist Site Insurance and a 10 Year Structural Warranty for your self build.
