The start of an exciting new chapter of co-operation 

Earlier this week, we proudly announced that Southern Co-op had become a subsidiary of the Co-op Group through Siena Co-operative Limited. This brings us one step closer to creating a combined co-operative society with greater scale, resilience and impact for our members, customers, colleagues and communities across the UK.  

Since early 2026, we’ve been working hard to reach this milestone, following Southern Co-op members’ vote in favour of joining forces with Co-op Group earlier this year.  

Although Southern Co-op is now legally part of the Group, the proposed merger remains subject to clearance from the Competition and Markets Authority (CMA).  Until that approval is given, Southern Co-op and Co-op Group will continue to operate separately and independently, with no immediate changes for members.
