About London Water Treatment

Who We Are

London Water Treatment provides specialist water hygiene and treatment services across all London boroughs. We deliver legionella risk assessments, chlorination services, and water tank cleaning for landlords, facilities managers, housing associations, and commercial property operators across the capital.

Our team of experienced engineers brings extensive knowledge working across London's diverse building stock — from Victorian residential conversions and social housing estates to modern commercial towers and heritage-listed properties. We understand the unique water treatment challenges that London buildings present.

Based in Kennington, we're centrally located to respond quickly across all London areas. Our emergency response service provides same-day attendance for urgent water safety issues, while our planned maintenance programmes deliver reliable, consistent service on schedule.

What We Do

We deliver three core services, each designed to keep your water systems safe, compliant, and reliable:

• • Legionella Control — comprehensive risk assessments, ongoing monitoring, and remediation programmes that meet ACOP L8 requirements.
• • Chlorination — emergency and planned water system disinfection following BS 8558 standards, with rapid response across London.
• • Water Tank Cleaning — professional cleaning, inspection, and disinfection of all storage tank types, with full certification.

Our Standards

All our work is carried out in accordance with HSE Approved Code of Practice L8, HSG274 technical guidance, and BS 8558. We provide detailed documentation for every job — giving you the evidence you need to demonstrate compliance.

We believe in transparent, straightforward service. We'll tell you exactly what we find, what needs doing, and what it will cost — with no pressure and no unnecessary work. Our goal is to help you manage water safety effectively and affordably.
