What Is a Legionella Risk Assessment?

A Legionella Risk Assessment is a legal requirement under the Health & Safety at Work Act, HSG 274 Part 2 Regulations, and HSE ACoP L8.

It identifies areas in your water systems where Legionella bacteria could grow and ensures your control measures keep staff, residents, and visitors safe

At LCS, we assess your entire water network from mains and calorifiers to outlets, showers, and thermostatic mixing valves to keep your buildings compliant and your people protected.

Specialist Schematic Drawings

Your Water System Schematic Is More Important

Than You Think

Most Legionella problems start long before a risk assessment they start with poor, outdated, or inaccurate schematics.

We regularly discover:

Drawings that do not reflect the real system
Missing assets (showers, dead legs, tanks, sentinel points)
“Copy-paste schematics” reused by previous consultants
System updates never added to the drawing
Conflicts between the RA and the schematic

This creates dangerous blind spots, leads to missed risk, and causes incorrect control measures.

✔ We specialise in creating accurate, compliant, engineer-grade schematics

As part of your assessment or a stand-alone consultation, we:

Inspect your full system layout
Map every key asset and flow route
Correct historic drawing errors
Update designs after system changes
Provide digital-ready schematic files
Ensure your RA and drawings align 100%

Result: You receive a schematic you can trust, one that finally reflects your real water system and supports full compliance.
