We're pleased to share some exciting news with our customers.

As of 31 July, SES Direct will officially transition to new ownership, with the existing management team taking over the business. Many of you will already know them—they've been integral members of the SES Direct team for several years and have played a significant role in building the business into what it is today.

As part of this exciting new chapter, we're also relocating to a new warehouse and office. Between 22 July and 30 July, we'll be moving into our new premises. During this time, there may be some minor delays with order dispatch and customer enquiries while we complete the transition.

Important Order Information

  • All orders placed up to 9:00 am on 31 July 2026 will be supplied and serviced by SES Direct Ltd.
  • All orders placed from 9:01 am on 31 July 2026 onwards will be supplied and serviced by SES Direct 2026 Ltd under the new ownership.

Rest assured, it's very much business as usual. Our supplier network will continue operating, and we'll be doing everything we can to minimise any disruption during the move.

I'd like to personally thank all of our customers, suppliers, and supporters who have backed SES Direct over the years. Your loyalty and support have made this business what it is today.

After more than 12 years building SES Direct, I'm incredibly proud to be handing the reins over to the team. They know the business inside and out, share the same commitment to customer service, and are well positioned to lead SES Direct into its next chapter.

While ownership is changing, you'll continue to see the same friendly faces, the same commitment to service, and the same passion for helping customers.

Thank you again for your continued support. We look forward to welcoming you to our new premises and continuing to serve you for many years to come.

Kind regards,

Alex McCallum
