Mains Chlorination for New Water Connections
When new water mains are installed, they are flushed and disinfected before being connected to the supply. Many water companies ask for a chlorination certificate and sample results before a new connection goes ahead. Requirements vary by company, so check your connection offer.
Internal Pipework Chlorination to BS 8558
Internal pipework chlorination is the process of disinfecting a building’s hot and cold domestic water systems prior to use. This is typically carried out during commissioning to ensure the system is free from contamination and safe to supply potable water to outlets such as taps, drinking points, and showers, in line with UK guidance.
Chlorination Certificates, Issued the Same Day
We issue your chlorination certificate on the day once the job has been paid for, with microbiological sample results following as soon as the UKAS-accredited laboratory reports them.

Frequently Asked Questions
What is pipework chlorination?
It’s the disinfection of new or altered water pipework before it goes into use. We flush the system, dose it with chlorine, leave it for the required contact time, then flush it again and take water samples for lab testing.
Do you chlorinate new water company connections?
Yes. We chlorinate private external MDPE mains up to 63 mm and internal pipework, and we plan the work around your connection date.
How quickly do I get my certificate?
We issue the chlorination certificate on the same day once the job is paid for. The lab sample results follow as soon as they come in. Read more about our chlorination certificates.
Do you offer water sampling and pressure testing?
Yes. We take water samples for microbiological testing at UKAS-accredited labs, and we carry out pressure testing on new pipework.
