No—a bathroom renovation on its own does not require an NT fidelity fund certificate, although the NT Government says it can require one when the bathroom is done with other work on a building that needs a certificate. The current prescribed-value trigger is $25,000, following reforms that commenced on 30 March 2026 (figures checked 1 October 2026). For an addition or extension, the detailed test is narrower: work must be over $25,000 and increase the property’s residential floor area.
How should a plumber classify a $25,000 bathroom job?
The NT Government’s scope table treats a bathroom renovation as not needing a certificate unless it is completed with other work to a building that does need one. The bathroom component’s price alone is not decisive.
For a plumber, the practical distinction is whether the job is bathroom-only or part of a wider addition or extension package. If the job includes prescribed residential building work, the builder must obtain a fidelity fund certificate for that job.
What kind of extension needs a certificate?
The NT Government applies two conditions to additions and extensions: the work must be over $25,000 and increase the property’s residential floor area.
| Project | Certificate position under the NT rules |
|---|---|
| Addition or extension to a house | Required when works are over $25,000 and increase floor area |
| Addition or extension to a duplex or townhouse | Required when works are over $25,000 and increase floor area |
| Addition or extension to flats less than three storeys, excluding undercroft or underground parking levels | Required when works are over $25,000 and increase floor area |
The detailed wording uses over $25,000, not simply $25,000 or more. The amount alone is insufficient: the floor-area increase is also required for this particular test.
Do prefabricated houses, garden sheds and fences need certificates?
The NT Government gives a clear “No” for each of these separate categories:
| Work | Fidelity fund certificate |
|---|---|
| Prefabricated house | Not needed |
| Garden sheds | Not needed |
| Fences | Not needed |
These are independent answers and do not themselves trigger a certificate. They may still form part of a larger job that contains prescribed residential building work, in which case the builder’s job-wide obligation applies.
Do the 30 March 2026 reforms affect older certificates?
The NT Government says the minimum prescribed value that triggers the need for a fidelity fund certificate increased from $12,000 to $25,000. The reforms reducing compliance costs for low-risk construction projects and relating to consumer protections commenced on 30 March 2026.
The amendments apply only to fidelity fund certificates issued after 30 March 2026. They do not retrospectively change certificates issued before that date.
Who must arrange the certificate?
If a job includes prescribed residential building work:
- Registered NT builders must apply to Fidelity Fund NT for an annual level of cover.
- Builders must show the financial capability and experience required for the level of cover sought.
- Builders must obtain a fidelity fund certificate for every client job containing prescribed residential building work.
- The certificate must be in place before obtaining a building permit for the prescribed work and before demanding payment from the owner.
Owner builders must also have a fidelity fund certificate to cover future owners for building defects. That cover becomes available only after the property is sold or transferred and the owner builder becomes bankrupt, dies, disappears or has their registration cancelled by the Building Practitioners Board.
Contact Fidelity Fund NT, currently the only provider in the Northern Territory, to obtain a certificate. Its contact details listed by the NT Government are (08) 8922 9680 and info@fidelityfundnt.com.au.
What costs can an owner claim, and how quickly?
The NT Government describes a fidelity fund certificate as the form in which residential building cover is issued and says it is similar to home warranty insurance cover in other states.
If a builder becomes bankrupt, dies, disappears or has their registration cancelled by the Building Practitioners Board, the certificate covers owners against listed costs, including:
| Listed cost | Timing stated by the NT Government |
|---|---|
| Transitioning to a new builder to complete the work | Applies when one of the listed builder events occurs |
| Rectifying non-structural defects | First year after completion |
| Rectifying structural defects | Six years after completion |
The cover timeframe for non-completion of work recognises any approved extension to a building permit.
A claim may be made within 90 days after becoming aware of a defect or after a trigger event occurs. The NT Government also states that a claim cannot be made if the builder has not died, disappeared, become insolvent or been deregistered.
This is general information, not financial or legal advice. Check the current regulator page and the Product Disclosure Statement for any relevant insurance policy before relying on its terms.

FAQ
Does a bathroom renovation costing $25,000 need a certificate on its own?
No. The NT Government lists a standalone bathroom renovation as not requiring a fidelity fund certificate. The amount does not independently change that answer.
What if the bathroom renovation is combined with other work?
A certificate can become necessary when the bathroom renovation is completed with other work on a building that requires one. For an addition or extension, the detailed test is work over $25,000 that increases residential floor area.
Is an extension exactly $25,000 enough?
The detailed additions-and-extensions entry says over $25,000, together with an increase in residential floor area. Although the reform summary identifies $25,000 as the minimum prescribed-value trigger, the detailed wording does not expressly say that exactly $25,000 is sufficient. Check the current regulator page for that borderline case.
Do the amendments apply to certificates issued before 30 March 2026?
No. The NT Government says the amendments apply only to fidelity fund certificates issued after 30 March 2026.
How long does an owner have to make a claim?
The NT Government states that a claim may be made within 90 days of becoming aware of a defect or a trigger event occurring. A claim is unavailable if the builder has not died, disappeared, become insolvent or been deregistered.
