Overview
New plumbing must be flushed and, where required, disinfected before it is brought into use. Existing systems may need disinfecting after a positive legionella result, a long period out of use or contamination. We plan the work to keep disruption low and issue certificates at the end.
What is included
- Disinfection of new installations and extensions
- Whole-system or targeted remedial chlorination
- Thermal pasteurisation where suitable
- Neutralisation and safe discharge
- Post-disinfection sampling
- Certificate of disinfection for handover

Frequently asked questions
