The Co-op Group and Southern Co-op have announced proposals to merge their operations, creating a larger entity with greater scale, resilience, and reach across the country.
The boards of both societies revealed the plans on Wednesday (8 April) describing the combination as a way to bring together two organisations with shared values and a common purpose.
If approved, the deal would integrate Southern Co-op’s approximately 300,000 members into the Co-op Group’s existing base of around 7 million, resulting in a combined membership of roughly 7.3 million.
Southern Co-op, which operates more than 300 food stores, funeral branches, and Starbucks coffee outlets primarily across the south of England, along with three crematoria, would transfer its engagements to the larger Manchester-headquartered Co-op Group.
The Co-op Group itself runs over 2,300 food stores, approximately 800 funeral homes, a wholesale business supplying around 8,000 outlets, and additional services in legal and insurance.
The transaction, structured as a “transfer of engagements”, a process which allows co-operative societies to combine, is subject to approval by Southern Co-op members and regulatory clearance, including from the Competition and Markets Authority (CMA).
Southern Co-op members are expected to vote on the proposals in May 2026.
If greenlit, the transfer could complete in the third quarter of 2026, with both businesses continuing to operate independently for a period afterward during the regulatory review.
Strengthening the co-op model
Executives from both sides framed the deal as a strategic step to secure the long-term future of Southern Co-op’s operations while enhancing opportunities for members, customers, colleagues, and communities.
Debbie White, Chair of The Co-operative Group, highlighted the historical depth of the move and that it would bring together over 300 years of co-operative experience.
“By coming together, we can secure the co-operative future of Southern Co-op as part of a stronger combined Co-op Group, whilst creating an even stronger voice nationally and internationally to advance the co-operative cause,” she said.
For Southern Co-op, the tie-up is positioned as a way to ensure sustainability amid challenges facing smaller or regional retailers, including intense competition from big supermarkets, discounters, and online players.
The deal would also allow Southern Co-op’s stores and funeral services to benefit from the Co-op Group’s larger scale in procurement, technology, and member offerings.
The combination is also expected to strengthen the broader co-operative movement, particularly in southern England, where Southern Co-op has a strong presence. It could enable expanded services and greater value for members through a wider range of co-op products and initiatives.
A big retail player
The UK grocery sector is highly competitive, with major players like Tesco, Sainsbury’s, and Aldi battling for share, while inflation and cost pressures have squeezed margins.
Co-operatives, which prioritise member dividends and community focus over pure profit maximisation, have faced their own pressures but maintained a loyal customer base through ethical positioning and local emphasis.
This deal could help the enlarged Co-op Group expand its footprint in the south, integrate Southern Co-op’s Starbucks-branded outlets, and re-enter or grow in the crematoria market, a segment seeing demand growth amid demographic shifts.
Both societies stressed that the proposals would safeguard jobs and services where possible, though detailed integration plans would follow member and regulatory approvals.
