Precision Built for Progress: How Dalkia Leads in Cleanrooms

When it comes to building complex, high-performance cleanrooms in the UK, our cleanrooms division is trusted by pharmaceutical, healthcare, electronics, and advanced manufacturing clients alike. Our capability to deliver some of the most technically demanding cleanroom environments doesn’t exist in isolation, it’s reinforced by a deep foundation of engineering, energy and technical expertise from across the Dalkia business.

From concept to commissioning, every cleanroom we deliver is backed by over 4,000 UK-based experts, £600m+ in annual revenue, and the support of EDF – our parent company and the UK’s largest generator of zero-carbon electricity.

The Specialist Strength Behind Dalkia Cleanrooms

Dalkia Cleanrooms is part of Dalkia Engineering’s Specialist Services Division, which also includes Electrical & Instrumentation, Infrastructure, and Nuclear Operations. This structure is more than an organisational chart, it’s a gateway to wider capabilities that directly enhance the cleanroom offer.

• Our Electrical & Instrumentation teams deliver fully integrated, safety-critical solutions, from power distribution and control systems to instrumentation and process automation for the heavily regulated industrial and manufacturing environments.
• Our nuclear and infrastructure specialists bring unparalleled experience in designing, delivering, and operating within some of the UK’s most demanding and high-risk environments, where precision and safety are non-negotiable.
• We apply the same methodical project execution, risk management, and compliance-first thinking from our operations to every cleanroom project.

This means cleanroom clients benefit not only from deep cleanroom expertise, but also from the collective precision of engineering teams who are used to operating in mission-critical environments.

Building for the Future: Cleanrooms and the Net Zero Challenge

Our work doesn’t stop at performance, we’re also helping clients meet their sustainability goals.

Supported by the energy services and decarbonisation expertise within the wider Dalkia and EDF group, our cleanroom builds are increasingly incorporating:

• Low-energy HVAC systems
• High-efficiency filtration and lighting
• Solar integration and smart controls
• Sustainable materials and recycling programmes

These cleanroom solutions not only meet the most demanding ISO and GMP classifications, they’re also contributing to the UK’s wider Net Zero goals.

In fact, Dalkia’s clients saved over 16,000 tCO₂e in 2024 through intelligent, sustainable infrastructure projects, a figure we’re actively contributing to with every cleanroom design we deliver.

Proven Capability at Every Stage

From delivering cleanrooms in high-profile research facilities like Leeds University to expanding biopharma manufacturing capacity in Teesside, our track record is proven.

We lead the full turnkey process, from RIBA Stage 3 design through to commissioning and validation, integrating BIM modelling, in-house delivery teams, and robust compliance pathways along the way.

And when we need to move fast, our scale and self-delivery model allows us to deploy resources rapidly, without compromising on quality or governance.

Conclusion

Dalkia is more than just a cleanroom provider, we’re a specialist team operating at the intersection of precision engineering, energy performance, and critical infrastructure delivery.

Our projects benefit from deep sector knowledge and the amplifying effect of the wider Dalkia and EDF network, giving clients a partner that can design, build, power and future-proof their cleanroom environments.
