NSW Professional Indemnity Requirements for Builders

What NSW builders and design practitioners need to know about Professional Indemnity insurance under the Design and Building Practitioners Act - and why the 30 June 2026 exemption deadline matters.

PI cover required

THE SHORT ANSWER

The exemption that let registered building practitioners trade without adequate PI insurance is due to end on 30 June 2026. From 1 July 2026, if you do design work on Class 2 buildings in NSW, you're expected to need adequate Professional Indemnity cover.

There's no fixed minimum sum insured under the Act - you need cover that's adequate for the nature and risk of your work. A Bill introduced in February 2026 could extend the exemption again, but it hasn't passed, so the safe move is to be ready for 1 July. If you take on design responsibility, you may also need Design & Construct cover or a higher PI limit for the contracts you're chasing.

DBP ACT OVERVIEW

What's Changing for NSW Builders?

The Design and Building Practitioners Act 2020 (DBP Act) introduced significant reforms to the building industry in NSW. One requirement is that registered practitioners hold Professional Indemnity insurance that is adequate for their work.

That requirement has been exempted year by year while the insurance market developed. The current exemption is due to end on 30 June 2026, so from 1 July 2026 registered design and building practitioners are expected to need adequate PI cover to keep working on regulated buildings. A Bill introduced in February 2026 could extend the exemption further, but it has not yet passed.

What this means for builders:

If you do design work on Class 2 buildings (apartments) or certain other building classes in NSW, you're likely to need adequate PI insurance once the exemption ends. This includes builders who amend designs, provide specifications, or take design responsibility on projects - the same builders who often need Design & Construct cover as well.

WHO'S AFFECTED

Who Needs PI Insurance Under the DBP Act?

The requirements apply to different types of building practitioners. Here's who needs to prepare.

  • Other regulated design practitioners
02 High likelihood

  • Builders who amend or modify designs
  • Builders who provide specifications as part of their service

COMPLIANCE CRITERIA

What Are the Insurance Requirements?

The regulations require practitioners to hold Professional Indemnity cover that is adequate for the nature and risk of their work, rather than a fixed minimum sum insured.

Adequate Cover (No Fixed Minimum)

The DBP Act does not set a fixed minimum sum insured. You must hold PI that's adequate for the nature, size and risk of your work - and be able to show how you reached that figure.

Cover for Your Design Work

Professional Indemnity that responds to the design and professional services you provide, structured to meet the criteria in the DBP Act regulations.

Run-off Considerations

Liability for design work can surface years after practical completion, so cover that continues to respond after a project finishes matters.

Important note:

The specific insurance requirements are set out in the regulations under the DBP Act. We recommend checking the current regulations or contacting us for the latest requirements, as these may be updated.

ACTION PLAN

How to Prepare

Don't wait until the deadline. Here's what you should do now to ensure you're ready.

01

Determine If You're Affected

Consider whether your work falls under the DBP Act. Do you do design work on Class 2 buildings? Are you registered (or need to be) as a design practitioner?

02

Check Your Current Insurance

If you have Professional Indemnity cover, review whether it meets DBP Act requirements. Not all policies qualify - you may need specific wording or a higher limit.

03

Talk to a Specialist Broker

The intersection of construction and professional liability is complex. A broker who understands both markets can help you get compliant cover.

04

Don't Wait Until the Deadline

The closer we get to July 2026, the more demand for compliant PI Insurance. Getting sorted now gives you more options and potentially better rates.

Getting the Right PI Cover

Professional Indemnity insurance for building practitioners needs to be structured correctly to meet DBP Act requirements. We work with specialist underwriters who understand the construction industry and can provide compliant cover.

What your PI policy needs to include:

  • Coverage for professional advice and design-related services
  • A limit that's adequate for the size and risk of your work (the Act sets no fixed minimum)
  • Run-off provisions for claims after project completion
  • Wording that satisfies DBP Act criteria

Building work itself is covered separately - Contract Works insurance protects the project, while PI responds to your design and advice. If a contract demands a higher limit, see high-limit PI.

If you're unsure whether you're affected, or need help finding compliant insurance, call us on 02 9000 1155.

Our team understands both the regulatory landscape and the insurance market for building practitioners.

NSW REQUIREMENTS FAQS

Common Questions About DBP Act Insurance Requirements

No, it primarily applies to registered practitioners doing design work on Class 2 buildings (apartments) and buildings with a Class 2 part. Builders who do design work on these building types may be affected. If you only build to designs provided by others with no design input, you may not need to register as a design practitioner.
It depends on your role. If you amend plans, provide specifications, or take design responsibility on projects, you may fall under the design-practitioner requirements. Separately, if you're a registered building practitioner who gives building compliance declarations for Class 2 or other regulated building work, the PI requirement can apply to you in that capacity too - not only for design work. If you purely construct to designs provided by registered design practitioners and don't give compliance declarations, you likely don't need to register, but you may still want PI insurance to protect against professional liability claims.
The Act does not set a fixed minimum sum insured. You're required to hold cover that is adequate for the nature, size and risk of your work, and you may be asked to show how you reached that figure. Because there's no set number, it's worth getting advice on an appropriate limit rather than guessing - and a contract you're tendering for may demand a specific limit on top of the regulatory requirement.
It's possible. The PI insurance requirement has been exempted year by year, and a Bill introduced in February 2026 could let the exemption continue. As things stand, the current exemption is due to end on 30 June 2026 and has not been formally extended, so the safe approach is to be ready for 1 July 2026 and we'll keep you posted if the position changes.
If you're required to hold PI insurance under the DBP Act and don't, it can affect your ability to keep your registration as a practitioner, which in turn affects whether you can do design work on regulated buildings in NSW. The practical answer is to arrange compliant cover before the exemption ends rather than risk a gap.
Not necessarily. The regulations specify criteria for the insurance, and your existing policy may meet some requirements but not others. We recommend having your policy reviewed to ensure it will be compliant and adequate for your work.
