Hello wfan,
For 3.5.3.1 there need to be a documented procedure (can be the same for purchase and raw material supplier). in this document it need to be stated what you are requiring from your service suppliers.
e.g. pest controller need to have llicense, laundering need to have certificate, transport need to have BRC S&D certificate and complete statement, etc.
So, if your financial manager comes to tell you that a service supplier is to expensive and he/she will look for another one, what the minimum requirements of such a service supplier?
Also this procedure needs to describe how you monitore these results. Most common is with a supplier evaluation/review.
for 3.5.3.2 you need to show contracts, stamements, agreements, etc. In these 'contracts' (does not need to be the official/legal one) the auditor will be searching for the requirements you stated in the procedure for 3.5.3.1 and the risks/control measures you indicate in the
HACCP-analyse or any other risk assessment required in BRC.
@GMO: If you have specific service SAQ, you have probably identified and documented the specific requirements for these service contractors as is required in 3.5.3.1.
If the SAQ also are signed and fulfil the need of a 'statement', this will be comply with 3.5.3.3.
if single order to a service supplier is agreed by this supplier, e.g. technical service in case of failure, this can be seen as a 'contract' as long as it is specific enough described.
