About Calson WIRS Services

WIRS Accreditation

The Water Industry Registration scheme enables contractors to gain accreditation as a WIRS provider or Self Lay Organisation (SLO). This is recognised by all water companies and Water UK.


To gain this accreditation, contractors must prove they can work to the scheme's requirements. This includes having full, comprehensive and WIRS compliant documentation to include: in-depth risk assessment and method statements, safe systems of work, and demonstrate management and quality assurance. You must also prove you have engaged a WIRS technical advisor.


Calson develops WIRS compliant documentation to enable your company to achieve and maintain the WIRS accreditation. We tailor methods, manuals, and procedures to your specific requirements and implement the system within your company.


We also act as a WIRS technical advisor, to ensure that you meet the WIRS requirements, but do so in a cost-effective way.
