CHAS ACCREDITED DRY RISER CONTRACTOR

WHY CHOOSE A CHAS-ACCREDITED CONTRACTOR?

Health and safety you can build into the programme. Dry riser design, testing, servicing and remedial works are delivered by a professional UK team with a safety-led approach throughout.

Working with a CHAS-accredited contractor provides added confidence that health and safety arrangements have been independently assessed.

At Dry Riser One, health and safety is built into how we plan, manage and deliver our work. From site access and coordination to installation, pressure testing and handover, our team works professionally and safely throughout every stage of the project.

Whether you require a new dry riser installation, remedial works, routine servicing or system testing, we provide a reliable service tailored to your building and programme.
