Correction to definition of motorhomes eligible for 12-month CoFs

From today (1 September 2025) private heavy motorhomes only need to get a Certificate of Fitness (CoF) every 12 months, instead of every 6 months.

The definition for an eligible motorhome that we included in earlier messages stated it could not be registered to a commercial entity. That’s incorrect - it can be registered to a commercial entity. It can’t be used for hire or reward or be operated under a transport service licence (TSL).

The correct definition for private heavy motorhomes eligible for the 12-month change is:

  • A vehicle with a gross mass of more than 3,500kg, not used for the carriage of passengers for hire or reward and not operated under a transport service licence. It's primarily used as a mobile dwelling and must include at least one sleeping berth with cooking facilities and a toilet.

We've updated the previous news item with the correct information.
