Willmott Dixon: Powering to a Greener Future with Oasis Solar Welfare Units

Enhanced Site Welfare through Solar Innovation

Our Oasis EcoLogic Solar welfare units provide a complete “instant start” solution for construction sites, delivering canteens, offices, toilets, and drying rooms that run primarily on renewable energy. Each unit integrates roof-mounted solar panels, advanced battery storage, and a low-carbon LPG backup system to create a dependable power source that performs year-round.

Over the two-year monitoring period, Willmott Dixon’s solar welfare fleet operated on renewable energy for almost 90% of the time, even during the darker winter months. This demonstrates the effectiveness of our innovative solar and hybrid technology in meeting site demands without compromising comfort or performance.

A Smarter Energy Mix

The EcoLogic Solar hybrid system delivers an intelligent balance between solar generation, energy storage, and efficient backup power:

• 50% of total electrical energy came directly from solar power.
• 33% was delivered through battery discharge, storing excess solar energy for use at night, on shorter or  cloudy days.

• The remaining 17% came from LPG – a much cleaner and more efficient alternative to diesel.

This smart energy mix ensures each welfare unit maintains consistent operation while dramatically reducing the environmental impact of traditional site welfare.

The Results Speak for Themselves

By replacing traditional diesel-powered units with our EcoLogic Solar welfare units, Willmott Dixon achieved impressive results over the two years:

• £450,000 in cost savings over two years, driven by reduced fuel use and maintenance.
• 1,000+ tonnes of carbon saved, thanks to using gas bottles instead of diesel – equivalent to roughly one-third of Willmott Dixon’s total carbon footprint.
• Noticeable reductions in air and noise pollution, improving site conditions for both workers and surrounding communities.

Using solar-hybrid welfare units also reduced site logistics, with fewer fuel deliveries required and minimal refuelling interruptions, further supporting efficient delivery across Willmott Dixon sites.

Supporting Willmott Dixon’s Sustainability Ambitions

Willmott Dixon has set ambitious goals to achieve Net Zero operational carbon by 2030, with sustainability embedded at every stage of its operations. The continued use of renewable-powered welfare units aligns perfectly with this mission, reducing reliance on fossil fuels while demonstrating leadership in sustainable construction.

Across its sites, Willmott Dixon continues to explore innovative solutions that enhance wellbeing, efficiency, and environmental responsibility – and the results from the Oasis EcoLogic Solar units reinforce the value of sustainable site welfare as part of its wider carbon reduction strategy.

Delivering Comfort, Convenience, and Confidence

Beyond energy performance, the Oasis Welfare range is designed with people and practicality in mind. Each unit offers instant setup with no external connections required, providing a fully functional and comfortable space from day one. Workers benefit from well-equipped canteens, modern washrooms, and quiet office spaces – all powered by solar-hybrid energy.

This combination of sustainability, reliability, and user comfort has made the Oasis range a trusted choice for Willmott Dixon’s teams, supporting both project efficiency and employee wellbeing.

Building a Sustainable Future Together

The success of Willmott Dixon’s solar welfare programme shows that high-performance welfare and low-carbon operation go hand in hand. By embracing proven solar technology, the company continues to demonstrate how innovation can deliver real progress toward a greener, more responsible construction industry.

As Willmott Dixon continues to pioneer sustainable building practices, Advanté remains proud to support this journey with welfare solutions that reflect shared values – delivering sustainable spaces built for tomorrow.
