What is Design and Construct Insurance?

Design and Construct Insurance (also called Builders PI) protects you if a client claims they lost money because of your professional advice, design services, or project management.

While Public Liability covers physical damage or injury (e.g., a wall falls on a car), D&C Insurance covers financial loss (e.g., the wall was designed incorrectly and has to be rebuilt).

If you draft plans, modify designs, or manage sub-consultants, you need Design and Construct (D&C) Insurance. This policy protects your business against claims of financial loss caused by design errors, incorrect specifications, or professional negligence.

You typically need this if you:

  • Draft your own designs or amend plans.
  • Hire consultants (engineers/architects) but take responsibility for their work.
  • Provide advice on materials or construction methods.
  • Are required by contract (D&C contract) to hold Professional Indemnity.

Public Liability covers accidents; D&C covers your professional advice and design risks.

COMMON QUESTIONS

FAQs about Builder's PI

You can get Professional Indemnity (PI) as a builder through a specialist construction insurance broker like Tank Insurance. General insurers often exclude "manual work" from PI policies, so builders require a specific "Design and Construct" policy that covers both their professional advice and their practical building activities. Learn more about our Professional Indemnity expertise.
Tradies can get PI insurance from construction-focused brokers like Tank Insurance who understand the specific design risks of their trade. Whether you are an electrician designing a circuit or a plumber planning drainage, you need a policy that covers the "advice" portion of your work, which standard Public Liability does not cover.
You can get PI through an insurance broker that specialises in Design & Construct insurance (also known as professional indemnity). This covers the liability for a specific job for the duration of the build and a "run-off" period afterwards. Contact Tank Insurance if you require this insurance.
If you are required to hold professional indemnity insurance, an insurance broker that specialises in design & construction insurance will be able to assist to obtain it, covering projects.
