From 30 March 2026, 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 relevant category is building work worth over $25,000 that increases a property’s residential floor area. The Department of Lands, Planning and Environment’s notice published 26 March 2026 says the amended regime allows a claim within 90 days of becoming aware of a defect or a trigger event occurring and applies only to certificates issued after 30 March 2026. New homes, duplexes and townhouses, qualifying low-rise units and other prescribed work remain in scope, while the NT guidance excludes prefabricated houses, standalone garden sheds, fences and a bathroom renovation undertaken on its own.
Figures checked 1 October 2026.
What does the $25,000 threshold actually apply to?
The $25,000 figure is a trigger for the relevant value-based category, not the amount of protection provided by the certificate. The NT guidance describes that category as building work worth over $25,000 that increases a property’s residential floor area.
It is not a blanket exemption below $25,000 for every residential job. Building a new home and other listed forms of residential building work are prescribed separately.
Which homes and other work remain in scope?
The NT Government’s prescribed-work examples include:
| Work | Fidelity fund certificate position |
|---|---|
| New house | Required; building a new home is prescribed residential building work |
| Duplex or townhouse | Required |
| Units in complexes up to three storeys, excluding undercroft or underground parking levels | Required |
| Additions and extensions to the specified residential buildings | Required for works over $25,000 that increase floor area |
| Renovations to the specified residential buildings | Listed as prescribed work, subject to the express exclusions below |
| Bed and breakfast work | Required unless the building is classified as Class 1b; contact the building certifier to discuss the requirements |
| Retaining wall for a residential building structure | Required |
This means the higher threshold should not be treated as removing the requirement for a new home or another independently prescribed project.
Which work does not need a certificate?
The exclusions are just as important as the floor-area threshold:
| Work | Position in the NT Government guidance |
|---|---|
| Prefabricated house | No fidelity fund certificate needed |
| Standalone garden shed | No fidelity fund certificate needed |
| Fences | No fidelity fund certificate needed |
| Bathroom renovation completed on its own | No, unless completed with other work on a building that does require a certificate |
| Retaining wall separate from, and not supporting, a residential building | No fidelity fund certificate needed |
| Flats greater than three storeys, excluding undercroft or underground parking levels | No fidelity fund certificate needed |
Residential building cover in the form of a fidelity fund certificate is also limited to residential building work. It does not cover commercial buildings, transportable buildings or government contracts.
Who must arrange the certificate, and when?
For prescribed residential building work:
- Builders must obtain a fidelity fund certificate for every job that includes prescribed work on behalf of their clients.
- The certificate must be in place before the building permit is obtained and before payment is demanded from the owner.
- Registered builders must apply to the fund for an annual level of cover and show the financial capability and experience required for the level sought.
- Owner builders must have a fidelity fund certificate to cover future owners for building defects.
Owner-builder cover is available only after the property is sold or transferred, and when the owner builder becomes bankrupt, dies, disappears or has their registration cancelled by the Building Practitioners Board.
The NT Government lists Fidelity Fund NT as the only provider in the Northern Territory, so builders and owners can contact Fidelity Fund NT to obtain a certificate.
What costs can a fidelity fund certificate cover?
The listed protection is connected to specified costs arising when the builder becomes bankrupt, dies, disappears or has their registration cancelled by the Building Practitioners Board.
| Listed cost or protection | Relevant period or condition |
|---|---|
| Transitioning to a new builder to complete the work | Available when the relevant builder event occurs |
| Rectifying non-structural defects | First year after completion |
| Rectifying structural defects | Six years after completion |
| Non-completion of work | The amended timeframe recognises any approved extension to the building permit |
The reforms therefore do more than change the monetary trigger: they also address the claim period and the treatment of an approved building-permit extension for non-completion cover.
How is this different from public liability insurance?
A fidelity fund certificate is residential building cover, which the NT Government says is similar to home warranty insurance in other states. Its listed costs concern completing work and rectifying structural or non-structural defects after a relevant builder event.
By contrast, business.gov.au’s insurance guidance describes public liability insurance as responding when someone dies, is injured or has their property damaged because of the insured’s negligence. The two forms of cover address different risks and should not be treated as interchangeable.
How does the 90-day claim period apply to older certificates?
The 90-day period forms part of the reforms that apply only to fidelity fund certificates issued after 30 March 2026. The amendments are not retrospective, so the changed provisions do not apply to an earlier certificate merely because a defect or trigger event occurs later.
The NT Government explains that retrospective application would change the liability attached to issued certificates for future claims and could affect the financial position of Fidelity Fund NT. The cited update does not state that the 90-day rule replaces the claim period in an earlier certificate.
For a certificate issued after 30 March 2026, a claim may be made within 90 days of either:
- becoming aware of a defect; or
- a trigger event occurring.
A defect alone does not establish eligibility for a fidelity fund claim. The NT guidance says a claim cannot be made if the builder has not died, disappeared, become insolvent or been deregistered. Where appropriate, the Commissioner for Residential Building Disputes can be contacted about mediating or deciding matters involving rectification or completion.
What should you check before work starts?
Before relying on the threshold or arranging cover, check:
- the exact description of the proposed work;
- whether the work increases the property’s residential floor area;
- the project value;
- whether the certificate was issued after 30 March 2026; and
- the current NT Government regulator page and any applicable policy’s PDS.
This is general information, not financial or legal advice. Requirements and claim terms should be confirmed against the current regulator guidance and the documents applying to the specific work or policy.

FAQ
Does the $25,000 threshold apply to every Northern Territory building job?
No. The relevant value-based category covers building work worth over $25,000 that increases a property’s residential floor area. New homes and other listed prescribed residential work remain subject to their own requirements.
Which homes still require a fidelity fund certificate?
The NT guidance lists new houses, duplexes, townhouses and units in complexes up to three storeys, excluding undercroft or underground parking levels. Prescribed renovations, extensions and other work may also require a certificate.
Are prefabricated houses, fences and standalone garden sheds excluded?
The NT Government says a fidelity fund certificate is not needed for a prefabricated house, garden sheds or fences.
Is a bathroom-only renovation always excluded?
A bathroom renovation completed on its own does not require a certificate. The position changes if it is completed with other work on a building that requires a fidelity fund certificate.
Do the 90-day claim rules apply to certificates issued before 30 March 2026?
No. The amendments are not retrospective and apply only to certificates issued after 30 March 2026. For an earlier certificate, check its own claim terms with Fidelity Fund NT rather than assuming the amended 90-day period applies.
