WELCOME TO POOLMARK!

POOLMARK is the UK National Standard that provides a certified assurance to operators and to the public, that the standards within the Code of Practice are being met.

The PWTAG Code of Practice provides pool operators with a structured plan for the technical operation of their pool. The Code ensures that the pool meets quality standards that provide a healthy experience for swimmers, including being able to deal with the threats from bacteria; chlorine resistant pathogens; and other infectious diseases.

It is based on the 2017 PWTAG book, Swimming Pool Water: treatment and quality standards for pools and spas, but does not replace it. It is for this reason all UK pools are encouraged to follow it.
