How PortmanDentex unified its Microsoft estate to improve collaboration, reduce costs and support future innovation

PortmanDentex is one of the UK’s largest dental groups, operating around 370 practices across the UK and Republic of Ireland. Following a period of rapid growth, including the acquisition and merger with Dentex, the organisation almost doubled in size, bringing thousands of new colleagues, systems, and ways of working together.
 

As the business expanded, so did the complexity of its Microsoft environment.

Multiple Microsoft 365 and third-party tenants made collaboration increasingly difficult, creating challenges around communication, licensing, governance, and day-to-day management. Even simple tasks, such as creating distribution lists, became unnecessarily complex across a highly fragmented estate.

Working alongside PortmanDentex, Atech helped consolidate the organisation onto a single Microsoft 365 tenant, creating a more connected, secure, and manageable environment for nearly 8,000 colleagues.

The consolidation has provided the business with a single view of its Microsoft estate, improving communication across the organisation while giving greater visibility of licensing, governance, and future planning.

As PortmanDentex continues to grow, the partnership has evolved beyond tenant consolidation. Together, we’re helping the organisation explore new opportunities across Microsoft technologies, including AI, Microsoft Teams, SharePoint, Microsoft Fabric, and the wider Microsoft ecosystem.

Rather than simply delivering technology, Atech works as an extension of the internal IT team, providing strategic advice, challenging thinking where appropriate, and helping the business make informed decisions as Microsoft continues to evolve.

The partnership also extends directly into Microsoft, helping PortmanDentex access funding opportunities, navigate new technologies, and maximise the value of its Microsoft investment without placing additional pressure on internal resources.

Alongside supporting innovation, the partnership has also delivered measurable commercial benefits, including more than £100,000 in Microsoft licensing savings and over £20,000 in Microsoft funding, with further savings expected as Azure adoption continues.

The partnership supports PortmanDentex with:

• Microsoft 365 tenant consolidation
• Microsoft licensing optimisation
• AI strategy and adoption
• Microsoft Teams and SharePoint innovation
• Microsoft Fabric planning and migration
• Azure optimisation and cloud adoption
• Access to Microsoft funding programmes
• Ongoing strategic guidance and managed Microsoft expertise

For PortmanDentex, the value of the partnership goes beyond technology.

Having a partner that takes the time to understand the organisation, offers honest advice, and proactively identifies new opportunities has helped build the trust needed to support a fast-growing business through significant change.

As the team explains, Atech’s willingness to challenge ideas, bring forward new thinking, and act as an extension of the internal IT function has become a key part of the relationship.

With a single Microsoft 365 environment now in place and a clear roadmap for future innovation, PortmanDentex is well positioned to continue modernising its technology, embracing AI, and delivering a better experience for colleagues across the business.
