(Contingency until 8am, Monday 6 October if needed)
Services Affected
During this time, the following systems will be unavailable:

What You Need to Do
Get paid on 30 September? Check Your Payslip Early
Managers and buyers: Clear Your IBC Inbox
If you use the IBC Portal, make sure to action everything in your ‘My Inbox’ before 24 September. This helps avoid delays in things like supplier payments.
Why This Is Happening
Our current system (SAP ECC) is reaching the end of its life, so we’re upgrading to a newer, more modern platform (SAP S/4HANA). This transition will be a significant step forwards in modernising our systems and enhancing capabilities. S/4HANA will provide future opportunities for us to develop faster, smarter insights, increase real-time data and analytics. As well as offer long term stability and support with a platform that is fit for the future.
What to Expect
You’ll still use the same tools — ESS Lite, the IBC Portal, and Learning Zone — and the way you use them won’t change much. But behind the scenes, we’re making big improvements to support you better and realise the potential of S/4HANA.
Once we begin the upgrade, we’ll publish communications to give you more detail on the small changes you can expect to see.
