Planned Downtime
From: 6pm, Wednesday 24 September 2025
To: 8am, Thursday 2 October 2025
(Contingency until 8am, Monday 6 October if needed)
Services Affected
During this time, the following systems will be unavailable:
- Employee Self Service (ESS)
- IBC Portal
- Learning Zone
- Internal Job Opportunities (OCC, OCC Schools and HCC Schools will still be able to view through the OCC intranet or Education Jobs)
But don’t worry — You’ll be paid as normal.
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 change will help us:
- Get faster, smarter insights with increased real-time data and analytics
- Improve system performance and integration through simplifying the IT landscape
- Prepare for future technologies including increased automation and AI
What You Need to Do
Check Your Payslip Early
We know how important it is to be paid accurately and on time — and that won’t change.
Our high-performing payroll team delivers consistently every month, and the upcoming system downtime and move to S/4HANA will not affect your pay. You can rest assured: you will be paid as normal.
If you work for OCC, OFRS, OCC Schools, HCC, or HCC Schools:
- you’ll have a shorter window than usual to check your payslip for September.
- Payslips are expected to be available around 18 September — please check yours as soon as possible.
- If something doesn’t look right, speak to your manager and raise an enquiry straight away. Emergency payments won’t be possible during the downtime, so it’s important to act quickly if anything needs attention.
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.
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.
We’ll keep you updated as we get closer to go-live. In the meantime, if you have any questions, please get in touch with the nominated contact for your organisation in the first instance and they will be happy to help.
