"A risk assessment revealed that our city centre offices had generally poor natural ventilation. This led us on a tricky quest to find a solution that not only brought in and circulated fresher, safer air, but also one that would not spoil the beautiful features of our historically listed building. After a detailed search for companies able to offer alternatives to the widely available standard ventilation machinery, we were lucky enough to find Sigma. They were the only company we met with who truly listened to our specific requirements and impressed us with their knowledge and enthusiasm for tailoring a system to satisfy our needs.

 

We are delighted with the end result of efficient and effective floor standing units with minimal footprints that are providing cleaner, fresher, healthier air. We are proud to have a vastly improved, tangibly fresh office environment that we are confident is safe and welcoming for our staff and visitors. Densley and his team were friendly and professional, always clear with their communication, pricing, planning and paperwork. Thank you team Sigma, we would not hesitate to recommend your services to others.
