Unless we have given you permission to do otherwise, you must only sub-contract to SIA approved contractors. Your customers have contracted an SIA approved contractor and will therefore expect the service they receive to be from an approved contractor.
In exceptional circumstances, we may allow you to sub-contract to a company we have not approved. You need our permission to do this and your customer must also agree to it. Any permission we grant will be for a limited time – usually no longer than 3 months.
How to ask for permission

Ideally, you should ask us for permission before you sub-contract the work. If this is not possible then you must do so within 5 working days after deployment.
How we make our decision
We review each application individually. We will consider your specific situation.
We will only give you permission if we agree that your circumstances are exceptional.
We will also consider:
- your track history of following ACS rules
- your efforts to avoid using a company we have not approved
- whether you could have prevented the situation by acting earlier
- any potential risk to public safety or the reputation of our approved contractor scheme
- the due diligence and quality checks you have done to confirm the sub-contractor meets the required ACS standard
- how you will align the sub-contracted service with ACS requirements (your ‘sub-contractor plan’)
We will try to reach a decision within 5 working days.

What counts as exceptional circumstances?
Exceptional circumstances are when your only option is to use a contractor we have not approved. This is usually when you have an urgent need and no SIA-approved contractor is available.
Some examples are:
- you need a specialised service, like a trained dog-and-handler team, and you cannot find an SIA-approved contractor who offers it
- you

Sub-contracting versus use of labour
‘Sub-contracting’ is different from ‘use of labour’. ‘Use of labour’ refers to hiring temporary workers. You do not need our permission to do this. Know the difference between sub-contracting and use of labour.
