How To Find And Appoint A Registered Certifier In NSW

If you’re building, renovating, or installing a shed or a pool in New South Wales, let us help you avoid unnecessary delays.. A registered certifier can issue key approvals such as Construction Certificates and Complying Development Certificates. When appointed as the Principal Certifier, they also carry out mandatory inspections and can issue an Occupation Certificate at the end when requirements are met.

My Certifier is based in the Illawarra,  and supports projects across the Illawarra, South Coast, Sydney, and the Highlands. This guide is written for property owners, builders, and contractors who want clear steps to find a certifier, appoint a certifier properly, and keep the approval process moving. 

If you’re ready to appoint a Building Certifier in our service areas, we’ll explain the key checks before signing, how to verify registration, and how to keep approvals moving.

Why Appointing The Right Certifier Early Matters

Engaging the right certifier early allows the certifier to provide you with guidance and direction during the application process. Often these clearly communicated instructions are all you need to get your development approved and started on time. Find a Certifier too late, and the process could be a mad scramble. This can result in short cuts and miscommunications that flow on, affecting the whole development and construction process. 

A clear appointment process helps avoid that stress. In NSW, certifiers are independent regulators who must uphold the public interest. They don’t work for the builder or developer, they work for the public interest.

When you find the right certifier for your job and set expectations upfront (scope, timing, documents), the project runs cleaner and you reduce the risk of avoidable compliance issues.

What A Registered Certifier Does (And Doesn’t Do)

It helps to know what you’re paying for.

A registered certifier can issue development certificates (such as CCs and CDCs) only when legislative requirements are met. If appointed as the principal certifier, they carry out mandatory inspections during construction and may request evidence that the work meets approvals and conditions.

If everything meets the development requirements at the final inspection, they can issue an Occupation Certificate.

A certifier is not a project manager or site supervisor. The builder remains responsible for building to the approved plans and managing subcontractors, and the applicant must meet consent conditions.

The Process For Finding And Appointing A Certifier

Most people don’t struggle because they’re unprepared. They struggle because the process feels unclear. The good news is that NSW has a clear appointment pathway, and once you follow it in order, the decision becomes much easier.

The aim is simple. Choose a certifier who is properly registered for your type of project, confirm their registration and insurance are current, and appoint them under a clear contract so inspections and certificates don’t become a last-minute scramble.

Step 1: Work Out What “Class” Of Certifier You Need

Not every certifier can certify every type of work. In NSW, there are different classes of certifiers for different building classes.

For residential projects such as new homes, alterations or additions to homes, sheds or garages, and pools, you’ll find us correctly qualified and experienced. 

Step 2: Find A Certifier Using The NSW Public Register (And Do Two Key Checks)

Once you know the type of certifier you need, NSW Building Commission recommends searching the Building Certifiers Public Register and doing key checks before you appoint.

NSW Building Commission’s checklist is practical:

• Check the certifier has the right class of registration for the work and read any conditions on their registration.
• Check their registration and insurance are current.
• Look them up on the certifier disciplinary register to see if decisions like cautions, reprimands, or fines have been recorded. This is separate to the public register, so checking both gives a fuller picture.
• Read the contract carefully before proceeding.

Step 3: Appoint A Certifier Properly (And Keep Control Of The Choice)

This part is simple, but important. Your builder isn’t allowed to appoint your certifier or influence your choice. The appointment sits with the owner or applicant, which can include owner-builder.

Before any certification work starts, NSW Building Commission’s guidance is clear that the certifier will ask you to sign a contract. That contract should spell out scope, fees, and what you need to provide to keep approvals moving.

A practical approach is to appoint your certifier as soon as you have enough documentation to quote accurately. This way, you’re not trying to book inspections or chase certificates at the same time you’re trying to start work.

What People Mean By “Registered Certifier” And “Accredited Certifier”

The wording can be confusing because people use different terms for the same role. In NSW, the formal term you’ll see in government guidance is registered certifier. This means the person or company is listed under the NSW system and is authorised to carry out certification work within the class of registration they hold. That includes issuing certificates like Construction Certificates and Complying Development Certificates when the requirements are met, and completing the certification role that leads to an Occupation Certificate where needed.

The term accredited certifier is outdated, but is still used widely in everyday conversation and in business branding, but in NSW the key point is not the label. The key point is whether the certifier is properly registered for the work you need them to do, has current insurance, and has the right class of registration for your project. That is why the safest approach is to verify them using the NSW registers before you sign anything.

If you are trying to find a certifier or appoint a certifier, focus on registration and capability rather than wording. A certifier can be called “accredited” on a website, but what matters is that they are a registered certifier under NSW rules, with the right registration class for your project type, and a clean record on the relevant registers.

If You Need To Replace A Principal Certifier Mid-Project

Sometimes relationships break down, timelines change, or a certifier becomes unavailable. 

NSW sets out two ways to replace a principal certifier:

1. By agreement (NSW says this is the quickest option), where the current and proposed replacement certifier agree to the change.
2. If you can’t agree, the owner can apply to the Building Commission NSW with good reasons. NSW Building Commission lists reasons such as:

• • Negligence
  • Incompetence
  • Breach of the Code of Conduct, plus relevant events, times, dates, and locations

NSW Building Commission also notes the proposed replacement must notify the council through the NSW Planning Portal within 2 days of appointment. The builder can’t apply to replace the principal certifier unless they’re an owner of the property.
