Marks and Spencer resumes online orders after two-month data breach disruption

After more than two months of disruption due to a major data security incident, Marks and Spencer has resumed online orders for its clothing range.

 

In a data security incident notice filed with the London Stock Exchange on April 22, M&S said it suffered a significant cyber security incident and immediately launched an investigation, with assistance from external cyber security experts, to determine the nature and scope of the same.

 

Last month, in a filing with the LSE, M&S projected an operating profit loss of up to £300 million for the 2025-2026 financial year.

 

“Since the incident, Food sales have been impacted by reduced availability, although this is already improving. We have also incurred additional waste and logistics costs, due to the need to operate manual processes, impacting profit in the first quarter.

 

“In Fashion, Home & Beauty, online sales and trading profit have been heavily impacted by the necessary decision to pause online shopping, however stores have remained resilient,” M&S said.

 

Furthermore, online disruption caused by the incident is expected to continue until July, after which operations will resume and gradually scale up. As a result, stock management costs are anticipated to rise in the second quarter.

 

In a recent update on its website, M&S said it has resumed accepting online orders, with deliveries now available across England, Scotland, and Wales. However, delivery services to Northern Ireland remain paused and are expected to resume in the coming weeks.

 

“We will resume Click & Collect, next-day delivery, nominated-day delivery and international ordering in the coming weeks,” the retailer said.

 

M&S has extended its standard delivery timeframe from 3-5 days to up to 10 days to ensure timely delivery for customers and adding that all available delivery dates will be displayed at checkout.

 

“More of our fashion, home and beauty ranges, as well as food and flowers, will be added over the coming weeks,” it added.
