Modular Clean Air (MCA) is now wholly owned by Total Clean Air (TCA), marking the next phase in its development following its successful launch as a joint venture in 2025.

Originally established to bring together modular construction and cleanroom expertise, MCA has quickly built momentum within sectors where speed, compliance and precision are critical. Now operating as TCA’s dedicated modular cleanroom brand, the business is well positioned to further strengthen its offer and respond to increasing demand for high-quality modular cleanroom solutions.
The move reflects continued investment in modular capability and confidence in the role MCA plays within TCA’s wider growth strategy. By bringing MCA fully in-house, TCA can offer a more integrated and streamlined approach to project delivery, combining specialist cleanroom knowledge with modular construction under one unified structure.
Demand for modular cleanroom solutions continues to rise, with the global market forecast to grow at over 12% annually, driven by increasing requirements across pharmaceuticals, life sciences and other highly regulated sectors.
End-to-end delivery model
This evolution supports a more efficient, end-to-end delivery model, providing clients with greater clarity, consistency and control across every stage of a project. It also enables closer alignment between design, build and compliance, particularly important for clients operating in regulated environments such as pharmaceuticals and life sciences.
MCA will play an increasingly important role within the TCA group, supporting clients with flexible, scalable and high-performance environments delivered at speed.
Phillip Godden, CEO at TCA, said: “This is a natural next step for Modular Clean Air following its successful launch last year. Bringing MCA fully into the business reflects the confidence we have in both the market and the capability we’ve built. It allows us to strengthen our modular offer and provide clients with a smarter, quicker and safer approach to delivery.
“We have an exciting pipeline of developments ahead, and MCA will play a central role in how we continue to evolve our offer and support clients in increasingly complex and fast-moving environments.”
