Is chlorination a legal requirement in Haringey?

Yes, in specific circumstances. BS 8558 requires chlorination for new installations, systems that have been substantially modified, and systems found to be contaminated. ACOP L8 also requires disinfection as part of remedial action when legionella or other contamination is detected in your Haringey property.

Who is responsible for arranging chlorination in Haringey?

The building owner, landlord, or duty holder with operational control of the water system is responsible. For new-build projects in Haringey, the contractor commissioning the system must ensure it is chlorinated before handover.

How long does chlorination take?

A typical chlorination in Haringey takes 4–8 hours including contact time, flushing, and sampling. Larger or more complex systems may require overnight treatment. We aim to minimise disruption and restore your water supply as quickly as safely possible.

What happens if chlorination reveals a problem?

If post-treatment sampling at your Haringey property shows that contamination persists, we investigate the root cause — this may include further system inspection, repeat treatment, or recommendations for pipework modifications to eliminate the source.

What chlorine concentration is used during treatment?

We follow BS 8558 guidelines, typically using 50 mg/l for a minimum one-hour contact time, or 20 mg/l for two hours. The exact dosing depends on the system and the nature of the contamination. After treatment, we flush until residual chlorine falls below 0.5 mg/l.

Is Chlorination a Legal Requirement?

Chlorination is required under BS 8558 whenever a water system is newly installed, substantially altered, or found to be contaminated. ACOP L8 also requires that contaminated systems are disinfected before being returned to service. Failure to disinfect can leave you exposed to prosecution under health and safety legislation.

The duty to ensure disinfection falls on the building owner, landlord, or whoever has operational control of the water system. Contractors commissioning new systems also have a responsibility to chlorinate before handover.
