Quick answer
There’s no single national expiry stamped on confined space training, but industry practice and most site requirements are a refresher every 1 to 3 years — often annually for high-risk sites. The nationally recognised unit (RIIWHS202E) doesn’t legally “expire,” but your skills currency does, and many workplaces and principal contractors require recent training to grant site access.
Why refresh confined space training?
- Procedures, equipment and gas detectors change
- Skills used rarely fade — and confined space errors are high-consequence
- Most sites and clients require current evidence before entry
Typical renewal periods
Many employers set 12 months for active confined space workers, and 2–3 years where entries are occasional. Always follow the stricter of your workplace policy and the site you’re working on.

Does RIIWHS202E expire?
The unit itself doesn’t carry a legal expiry, but currency matters and many sites require recent training for entry.
Do I redo the whole course to refresh?
Refresher training re-establishes currency; check your employer’s policy for what they require.
