Upon installation of a new water system, it is a legal requirement for it to be flushed and disinfected (pre-commissioned). Along with this, all new domestic pipework installations, or modifications of same, must also be disinfected before being used.


After the on-site chlorination works we send off the samples to independent UKAS certified water testing services laboratories for the final verification of the integrity of your water. The results of which then completes the process and allow us to issue you your Chlorination Certification.
