When you need a waterproofing licence

You must have a licence before you do any residential building work in NSW, including waterproofing, that is valued at more than $5000 in labour and materials (incl GST).

What is waterproofing?

Waterproofing is any protective treatment of a home to prevent water or moisture getting into it.

It is also the protective treatment of wet areas of a home (such as a shower) to stop the unwanted escape of water from those areas.

The protective treatment used is solid membranes or membranes applied by brush, roller or any other method.

To learn more about what is considered waterproofing work, see the definition in schedule 4 of the Home Building Regulation 2014.

Licence types

Waterproofing is trade work.

There are different types of licences available in NSW depending on whether you want to contract for another party, supervise work, do the work, or a combination of these roles.

Contractor licence

A contractor licence allows you to contract and advertise to do work. You can only do the types of work described on your licence card. Contractor licences can be issued to individuals and to companies and partnerships.

You can apply for a 1, 3 or 5 year licence.

Qualified supervisor certificate

A qualified supervisor certificate allows you to supervise and do the work described on your certificate. Qualified supervisor certificates are only issued to individuals. A qualified supervisor certificate does not allow you to contract for work.

You can apply to have a qualified supervisor certificate issued for 1, 3 or 5 years.

Endorsed contractor licence

An endorsed contractor licence is issued to individuals who apply for a contractor licence and who also have the qualifications and experience needed to be a qualified supervisor. Endorsed contractor licence cards have ‘contractor licence (Q)’ printed on them to show they are also equivalent to a qualified supervisor certificate.

Qualifications needed

To get a licence or certificate to do waterproofing work, you need one of the qualifications listed below:

• CPC31420 (current) Certificate III in Construction Waterproofing or
• CPC31411 / CPC31408 Certificate III in Construction Waterproofing or
• BCG31403 Certificate III in Waterproofing (General Construction) or
• Qualification 90464 Certificate III in General Construction (Waterproofing) TAFE course #8126.

To find organisations that deliver nationally recognised training, go to training.gov.au and search for the course code or name.

If you are currently an apprentice or trainee, you cannot apply for a licence or certificate. You must apply as soon as you finish your apprenticeship or traineeship to be able to keep working.

If you hold a licence from interstate or New Zealand, and want to work in NSW, see Working interstate and mutual recognition.

Previous licence or certificate holders

You do not need to show your qualifications if:

• you have ever held an endorsed contractor licence or qualified supervisor certificate in waterproofing that had no restrictions or conditions. If you apply for a new endorsed contractor licence or qualified supervisor certificate, we will accept your previous licence or certificate in place of the current qualification requirements.
• you have held an endorsed contractor licence or qualified supervisor certificate in the last five years in waterproofing that had restrictions or conditions (not including the endorsements listed above). We will assess your application and reissue you a licence or certificate that reflects the scope of work that your licence or certificate covered. This may include some conditions or restrictions.

We will send you a renewal form several weeks before the expiry date with details on how to renew. We may also send you an SMS reminder.

If your licence is going to expire soon and you have not received your renewal form, contact us on 13 32 20. It is your responsibility to renew your licence on time.

Change the details on a licence

As a licence holder, it is your responsibility to tell us within 7 days if your name, address or other details change.

Change of address and contact details

Update your name

Change of licence class

If you gain further qualifications that allow you to work in additional classes, you can add or change a class on your contractor licence or qualified supervisor certificate at a Service NSW Centre.

Before you begin your application, make sure you have:

• an Application Form - Individual
• a relevant Checklist for Individuals (if applicable)
  • General Building Work
  • Specialist Work
  • Other Building Work and Trade Work

  Change the conditions on a licence

  Your licence or certificate allows you to do and/or supervise the work described on your licence card, subject to any specified conditions.

  These conditions may be imposed for a number of reasons to limit the scope of work you are able to do or place other requirements on the licence or certificate holder.

  They may be as a result mutual recognition processes, disciplinary action, bankruptcy, external administration or other factors.

  If your circumstances change (such as your qualifications), and this affects the conditions under which your licence or certificate has been issued, you must let us know within 7 days and you'll need to amend your details. You can do this at a Service NSW Centre.

  Before you begin your application, make sure you have:

  • an Application Form - Individual, or a letter explaining the details of the condition change
  • proof of identity
  • one passport size photograph (if applicable)
  • evidence of qualifications or documentation to validate the change of condition
  • payment for the fee.

  Working interstate and mutual recognition

  There are different ways that make it easier for many licensed or registered professionals to work interstate.

  If you trained overseas see Overseas Trained Applicants. Qualifications from overseas are not approved for licensing in NSW.

  Automatic mutual recognition

  Automatic Mutual Recognition (AMR) allows individuals who hold some specified licences issued in other Australian States and Territories to work in NSW under that licence without the need for a local licence or paying additional fees (please note: Queensland is not a participating state).

  The AMR scheme does not apply to New Zealand occupational registrations and licences. However, existing processes under the Trans-Tasman Mutual Recognition Arrangements continue to apply.

  Recognised interstate licensees will not need a NSW licence unless they relocate their primary place of residence to NSW. This is similar to someone with a driver’s licence issued by another state being able to legally drive on NSW roads; only if they move to NSW do they need a NSW driver’s licence.

  While working in NSW, a recognised interstate licensee must follow the same laws as NSW licence holders. Fair Trading can take disciplinary and enforcement action if these obligations are not met.

  Waterproofing is included in the AMR scheme. If you hold an eligible interstate licence, you are required to notify NSW Fair Trading of your intention to work in NSW .

  If not eligible, other licence holders may still be able to apply under mutual recognition to have their licence recognised in NSW.

  Mutual recognition

  Mutual Recognition (MR) arrangements enable a licensed tradesperson or registered professional to work in another state or territory by having their qualifications recognised in NSW and vice versa.

  Under MR you can practise an equivalent occupation in NSW if the activities you're authorised to carry out under your original licence are substantially the same as those under the occupational licence in NSW.

  To apply for recognition of your existing licence, you need to:

  • complete a Registration of equivalent occupation form, and
  • pay any applicable fee.

  Applications, payment and supporting documents must be lodged at a Service NSW Centre.

  Insurance requirements

  If you are a licensed builder or tradesperson in NSW, you need to get home building compensation (HBC) cover for each home building project over $20,000 including GST.

  HBC cover, which used to be called ‘home warranty insurance’, protects homeowners as a last resort if you cannot complete building work or fix defects.

  Insolvency matters

  Current bankruptcy and external administration

  If you are applying for a licence and are currently bankrupt or the director of a company that is under external administration (other than external administration resulting from a member's voluntary winding up of the body corporate), a contractor’s licence may be granted with the condition 'contracts not to exceed $20,000 in value'.

  Bankruptcy or external administration within three years

  If you are applying for a licence and have been discharged from bankruptcy or were previously a director of a company in external administration (other than external administration resulting from a member's voluntary winding up of the body corporate), and if we grant you a contractor licence, it may come with the condition:

  • contracts not to exceed $20,000 in value, or
  • contracts not to exceed $20,000 in value, except for subcontract to licensed contractor.

  Cancelled or suspended licences

  Your licence or certificate can be cancelled or suspended if you:

  • become involved in unlawful activity
  • get a licence by misrepresentation or fraudulent means
  • become bankrupt or subject to a winding up order.

  Also, if the holder of a company or partnership licence goes more than 30 days without an acceptable nominated supervisor, without prior consent from Fair Trading, the licence will be cancelled.

  If your licence is cancelled, we will not refund any of the fees paid.

  Immediate action required

  If your licence or certificate has been cancelled or suspended you must immediately:

  • stop all business activity that relates to the licence or certificate
  • remove any sign or advertisement which indicates the conduct of business activity that relates to the licence or certificate
  • return the licence or certificate to NSW Fair Trading by mail or at a Service NSW centre.

  You should also let your clients know, either verbally or in writing, that your licence has been cancelled or suspended and you are unable to complete any unfinished work.

  Automatic licence suspension

  Your licence will be automatically suspended if you do not comply with an order by a court or the NSW Civil or Administrative Tribunal (NCAT) to pay money for a building claim.
