How to Get an Engineering Certificate for a Car in Australia

An engineering certificate for a car in Australia may be required if you modify your vehicle — whether for accessibility modifications, performance upgrades, or structural changes. This certificate confirms that the vehicle modifications comply with Australian Design Rules (ADR) and the National Code of Practice for Light Vehicle Construction and Modification (NCOP).

Understanding the certification process is important for vehicle owners, driving instructors, and NDIS participants who require vehicle accessibility modifications.

What Is an Engineering Certificate for a Car?

An engineering certificate is an official report issued by an approved automotive engineer confirming that vehicle modifications meet Australian safety, structural, and compliance standards.

The engineer assesses the vehicle modifications against:

• Australian Design Rules (ADR)
• National Code of Practice (NCOP / VSB14)
• State vehicle modification regulations
• Vehicle safety and structural integrity requirements

Once approved, the certificate can be submitted to the relevant transport authority to support vehicle registration or modification records.

Common Vehicle Modifications That Require Engineering Approval

Engineering certification is typically required when major modifications are made to a vehicle. These include:

• Wheelchair accessible vehicle conversions — lowered floors, ramps, lifts
• Adaptive driving controls — hand controls, left foot accelerators, spinner knobs
• Dual control pedal systems — required for driving school vehicles in NSW
• Engine swaps or major engine upgrades
• Chassis or frame modifications
• Suspension lift kits or structural suspension changes
• Brake system upgrades
• Custom-built or kit vehicles

Many accessibility modifications must be carefully engineered to ensure they meet safety and compliance requirements. Gilani Engineering designs and installs accessibility vehicle solutions with certification included — see our full range of vehicle modifications.

Engineering Certification in NSW — VSCCS

In New South Wales, many modified vehicles are certified through the Vehicle Safety Compliance Certification Scheme (VSCCS). Authorised VSCCS engineers inspect vehicle modifications to ensure they meet regulatory requirements before issuing a compliance certificate.

The inspection typically reviews:

• Structural design and load paths
• Brake and suspension performance
• ADR compliance
• Vehicle stability and safety systems
• Installation quality of modified components

Once approved, the engineering report can be submitted to Transport for NSW as part of the registration or modification approval process.

Gilani Engineering has an in-house VSCCS certifier at our Wetherill Park workshop. For vehicle modifications we perform — including dual controls, wheelchair accessible conversions, and adaptive driving controls — certification is included in the installation package. Note that we provide certification only for modifications carried out by our own team, not for externally performed work.

Engineering Certification in Other States

• Victoria: Vehicle modifications are assessed under VicRoads guidelines. Modified vehicles may require inspection and approval through an authorised engineer before re-registration.
• Western Australia: Vehicle engineering certificates in WA are issued by approved examiners through the Department of Transport. VSB14 compliance applies.
• Queensland: Modifications must comply with Queensland Department of Transport and Main Roads requirements. A Certificate of Inspection may be required.
• Other states and territories: Requirements vary. Always confirm with the relevant state transport authority before modifying a vehicle.

How Much Does a Car Engineering Certificate Cost?

The cost of an engineering certificate in NSW and Australia varies depending on the complexity of the modification, the certifier, and whether the modification was performed by the certifying workshop or externally.

For vehicle modifications performed by Gilani Engineering — including dual controls, wheelchair accessible conversions, and adaptive driving aids — VSCCS certification is included in the installation price. Contact us for a quote on your specific vehicle and modification.

Steps to Obtain an Engineering Certificate

1. Determine whether certification is required

Confirm whether your vehicle modification requires engineering approval under your state’s transport regulations. For accessibility modifications and dual controls in NSW, certification is mandatory.

2. Choose a certified workshop or engineer

Where possible, choose a workshop with an in-house certifier — this simplifies the process and often reduces cost and turnaround time. Gilani Engineering’s Wetherill Park workshop includes an in-house VSCCS certifier for all modifications we perform in-house.

3. Vehicle inspection

The engineer performs a detailed inspection covering structural integrity, brake performance, steering and suspension, component installation quality, and ADR compliance.

4. Engineering report issued

If the vehicle meets the required standards, the engineer issues a formal engineering report confirming compliance with relevant safety regulations.

5. Submit to transport authority

The certificate is submitted to Transport for NSW (or the relevant state authority) as part of the registration or modification approval process.

Engineering Considerations for NDIS Vehicle Modifications

Vehicle modifications funded through NDIS often require careful engineering design to ensure accessibility, safety, and compliance. Examples include:

• Wheelchair vehicle access systems — ramps, lowered floors, NoRamp® conversions
• Adaptive driving controls — hand controls, left foot accelerators, spinner knobs
• Dual control pedal systems — for driving school vehicles
• Vehicle lifts, transfer seats and custom restraint systems

Gilani Engineering specialises in mobility engineering, adaptive driving controls and accessibility vehicle modifications. NDIS vehicle modification funding may be available — request an NDIS quote here.

Frequently Asked Questions

What is a VSCCS engineer in NSW?

A VSCCS (Vehicle Safety Compliance Certification Scheme) engineer is an authorised engineer approved by Transport for NSW to inspect and certify vehicle modifications. They confirm that modifications meet ADR, NCOP and NSW road safety requirements.

How much does a car engineering certificate cost in NSW?

Cost varies depending on the modification complexity and certifier. For modifications performed by Gilani Engineering, VSCCS certification is included in the installation price. We do not provide standalone certification for modifications performed elsewhere.

Where can I get a car engineering certificate near me in NSW?

Gilani Engineering’s workshop at 99 Cowpasture Rd, Wetherill Park NSW 2164 performs vehicle modifications with in-house VSCCS certification included. We certify modifications carried out by our own team — if you need a modification done and certified, call (02) 8740 8963 to discuss your requirements.

Do dual controls for driving instructors require an engineering certificate?

Yes. Dual control installations in NSW require RMS/VSCCS certification. Gilani Engineering installs dual controls with certification included — see our dual controls range.

Do wheelchair accessible vehicle conversions require an engineering certificate?

Yes. Wheelchair accessible vehicle conversions are major structural modifications that require engineering certification before the vehicle can be re-registered. Gilani Engineering performs these conversions with certification included.

Can NDIS fund vehicle modification engineering costs?

NDIS vehicle modification funding may cover the cost of accessibility modifications including engineering and certification where the modification is considered reasonable and necessary. Contact Gilani Engineering for an NDIS vehicle modification quote.
