Water Surveys and Inspections to Keep Your Systems Safe, Compliant & Efficient

When it comes to water hygiene, prevention is key. At L8 Protection, we specialise in carrying out detailed on-site surveys and inspections designed to safeguard your water systems against Legionella and other waterborne risks.

Our trained water engineers take a hands-on approach, inspecting, testing, and evaluating every aspect of your system to make sure it’s performing safely and in full compliance with ACoP L8 and HSG 274 guidance. Whether you’re responsible for a single building or a large estate, our goal is simple: to help you stay compliant and protect the people who use your water every day.

Why Regular Surveys and Inspections Matter

Your water system is a living network; temperature changes, stagnation, and biofilm can all create opportunities for harmful bacteria like Legionella to grow. That’s why regular surveys and inspections are so important.

Here’s what they help you achieve:

• Spot potential problems early - Catching issues like poor temperature control, scale, or stagnation before they become a health hazard.
• Stay legally compliant - ACoP L8 and HSG 274 require you to monitor and manage your systems properly. Regular inspections are key to meeting these duties.
• Prove your due diligence - Detailed inspection records demonstrate that you’re actively managing risk, protecting your business as well as your building users.
• Improve system performance - Our inspections often uncover ways to optimise efficiency, reduce energy use, and extend system lifespan.

What’s Included in an L8 Protection Survey

Every building is different, so we tailor our surveys to match your site and its specific risks. Here’s what you can expect when we visit:

System & Asset Review

We start by mapping out your water systems, creating or updating a full asset register and schematic. This helps identify where potential risk areas may exist, such as dead legs, calorifiers, cold-water tanks or thermostatic mixing valves (TMVs).

Temperature Mapping & Monitoring

Our engineers test water temperatures across key outlets to ensure hot and cold systems are operating within safe ranges. We look for inconsistencies and identify areas that could support bacterial growth.

Visual Inspection & Hygiene Check

We carry out a detailed visual review of tanks, pipework, strainers, filters and fittings. During this, we assess the cleanliness of components, look for scale, corrosion or biofilm, and check whether regular flushing and maintenance routines are being followed effectively.

Flow & Circulation Assessment

We test system flow rates and identify any sections of pipework that aren’t circulating as they should. This helps pinpoint stagnation risks and provides insight into how the system could be rebalanced or improved.

Sampling & Laboratory Testing

Where required, we take water or swab samples for Legionella and microbiological analysis at UKAS-accredited laboratories. We interpret the results and provide practical guidance on next steps.

Clear Reporting & Recommendations

After every survey, you’ll receive a detailed report outlining our findings, supported by photographs, risk scores and tailored recommendations. We’ll also highlight priority actions to help you address any immediate concerns.

How Often Should You Have a Water Survey & Inspection?

The frequency of your surveys depends on your system type, level of use and overall risk.

For low to medium-risk sites, such as offices, schools or hotels, we typically recommend carrying out inspections every three to six months to check temperatures, perform visual assessments and review flushing routines.

High-risk environments, including healthcare settings or large commercial sites, often benefit from more frequent visits, bi-annual or quarterly inspections help maintain control and catch problems early.

Every site should also have a comprehensive survey at least once a year, to update schematics, reassess risks and refresh your documentation. If you make system changes, add new assets or notice performance issues, an additional survey may be necessary.
