Certified self-contained vehicles and the green warrant

Where the rules now stand

The regulated system came in under the self-containment legislation and took effect in stages. From 7 June 2025, new certifications required a toilet fixed into the vehicle and issued a green warrant. Blue warrants issued under the older standard, which permitted portable toilets, remain valid until they expire, and no later than 31 December 2027.

Once that period closes, a blue warrant will no longer establish compliance, and any vehicle relying on self-containment for freedom camping will need a current green Certified Self-Contained warrant. If you own a converted van certified under the old standard with a portable toilet, plan for a fixed toilet and recertification before the deadline rather than after it.

What the certification actually tests

The standard checks that the vehicle can support its occupants for three days without external services. That means a toilet fixed in place and usable inside with the bed made up, fresh water capacity, wastewater storage sized to match, a sink, and a sealed rubbish container, all scaled to the number of people the vehicle is certified for.

The certified occupancy matters and is frequently overlooked. A van certified for two people does not become compliant for four because four can fit on the bed. Enforcement checks the warrant against the people present.

What it does not give you

A green warrant is not permission to camp. It does not override a bylaw prohibiting overnight stays, does not create a right to a marked bay, and does not extend a stay limit. Where a council prohibits freedom camping, a certified vehicle is as prohibited as any other.

It also says nothing about roadworthiness. Warrant of Fitness, registration, gas certification and the rental company's own conditions are separate obligations, and a self-containment certificate does not imply any of them have been met.

Verifying a warrant before you commit

Every certified vehicle is listed on a public register searchable by registration plate. Check the plate rather than the sticker: warrants expire, vehicles get sold, and a card in the window proves very little on its own. Confirm the expiry date covers your entire trip, not just the pick-up date.

For a rental, ask the depot to confirm the certification and occupancy in writing before you drive away, and photograph the warrant and the plate together. If a rental turns out to be uncertified mid-trip, the infringements are yours to argue about later.

Buying or converting a vehicle

If you are buying a conversion, use an approved certification authority for the inspection rather than accepting the seller's assurance. Ask specifically what would need to change to satisfy the current standard, because a van marketed as self-contained may have been certified under rules that no longer apply.

If you are converting, involve the certifier early. Plumbing routes, tank sizes, toilet mounting and ventilation are much cheaper to get right during the build than to retrofit afterwards, and some alterations can affect gas or electrical compliance at the same time.

Living up to the certificate

Certification assumes the systems are actually used. Carry the toilet chemicals, empty tanks at proper dump stations, and keep the rubbish container sealed. A certified vehicle whose occupants use public toilets and tip grey water into a hedge is precisely the behaviour the standard exists to prevent.

Know your tank capacities in days rather than litres, how long before the fresh water runs out, how long before grey water needs emptying. That converts a specification into a planning tool, which is what makes the difference between a comfortable week and an unplanned detour.
