Comfort Services Group provides professional Legionella Risk Assessment services across West London for businesses, landlords, and property managers.
We’re local, fast, and practical — helping you understand your responsibilities and stay compliant with confidence.
This helps to reduce exposure and maintain ACOP L8 compliance, and all that without making the process heavier than it needs to be.
Real buildings are not tidy on paper. Offices change use. HMOs get busy. Warehouses sit quiet in places. Clinics, schools, managed residential blocks, and other places all carry different pressures. Where water systems exist, legionella risk needs proper attention. Not guesswork. Our legionella risk assessments help identify legionella growth and set clear control measures. It keeps legionella control documented, manageable, and ready for action.
Why Is a Legionella Risk Assessment Required?
A Legionella Risk Assessment is required because UK health and safety laws are clear. Very clear. Employers, landlords, and anyone in control of premises have legal duties. They cannot ignore potential risks. Under the Health and Safety at Work Act 1974, the Duty Holder must act. Identify the risk. Apply suitable control measures. Protect people who may be exposed.
This is not paperwork. Not a box-ticking exercise. Legionnaires disease is a potentially fatal form of pneumonia. Older people face higher risk. So do heavy drinkers. Smokers too. Anyone with an impaired immune system or chronic respiratory illness is more vulnerable. That is why the assessment matters. It protects people first. Then it protects the property.
Non-compliance can lead to:
Fines and enforcement action
Serious health risks for tenants, staff, and visitors
Civil claims and reputational damage
Breaches of insurance or contractual obligations
Failure to stay compliant with hse guidance
A proper risk assessment helps identify where legionella bacteria may grow, how people could inhale tiny water droplets, and what preventive measures are needed. It also supports legionella compliance, record keeping, and a practical written scheme where required. For any West London property manager, this is a critical safety requirement. Not optional. Not something to leave until there is a problem.

What Our West London Assessment Includes?
A professional assessment looks beyond visible taps and showers. It considers the full system, how water moves, where it stagnates, who uses the property, and whether the building is being properly maintained. Comfort Services Group provides a structured process that follows established guidelines, approved code of practice expectations, and relevant british standards.
The aim is clear. Identify the legionella risk, confirm the current condition, and recommend proportionate action. Where higher risk systems exist, such as cooling towers, evaporative condensers, spa pools, or hot tubs, we assess the system with added care and suitable technical judgement.
Site Survey & Asset Inspection
Our site survey begins with a practical walkthrough of the property. We inspect visible pipework, outlets, calorifiers, tanks, dead legs, sentinel points, and any areas where water may sit unused. We also check cold water systems, hot and cold water routes, and storage tanks, looking for potentional issues that could encourage bacterial growth.
This is a thorough inspection, not a quick glance. We look at condition, access, insulation, usage patterns, and whether assets are properly maintained. In larger commercial buildings, we also consider plant rooms, process equipment, and purpose built water systems.
Temperature Profiling & Testing
Temperature control is central to legionella control. The reason is simple. Bacteria thrive in warm water, and legionella bacteria growth is most likely between 20°C and 45°C, with concern across the wider 20°C to 60°C range. During the assessment, we check water temperature at relevant outlets and compare findings against expected control standards. Where needed, we may recommend legionella testing, water testing, or taking water samples for laboratory analysis. Testing is not always required, but when the system or evidence suggests uncertainty, it becomes a useful step. Better evidence. Better decisions.
Professional Reporting & Remediation
After the assessment, you receive a clear digital report setting out findings, risk ratings, photographs, and required actions. No vague notes. No confusing technical dump. The report explains where legionella bacteria found conditions may occur, what needs attention, and which remedial works should be prioritised.
This may include flushing, pipework changes, tank cleaning, temperature correction, outlet cleaning, or changes to routine monitoring. Comfort Services Group can also help complete the work, so you are not left searching for another contractor. That gives property owners peace of mind, documented evidence, and a practical route to ensure compliance.
Sectors We Serve in West London
Comfort Services Group supports a wide range of West London buildings, each with different occupancy patterns, access pressures, and water use. Commercial offices in Chiswick Park or Hammersmith often have complex plant rooms, shared washrooms, and irregular floor usage. Residential landlords in Ealing or Fulham may need assessments for HMOs, rental flats, or a single residential property between tenants. Industrial clients in Hayes or Hounslow may operate warehouses, workshops, loading areas, welfare blocks, and production spaces. Each site is different. So the assessment must be different too, especially where potential risks increase because of low use, stored water, or vulnerable users.
We also work with schools, clinics, hospitality venues, retail units, managed estates, and mixed-use blocks. Some sites need simple preventive measures. Others need a more detailed programme because they have five or more employees, multiple outlets, stored water, or complex infrastructure. Where legionella proliferation could occur, we help clients understand the source, the people at risk, and the right level of control. Our role is not to overcomplicate the process. It is to make the building safer, the records clearer, and the next step easier to manage.

Comfort Services Group combines local coverage, technical competence, and a straightforward service model.

No hidden extras. No uncomfortable surprises. Our engineers understand water hygiene, legionella, and the practical reality of managing busy buildings. We assess, report, advise, and where needed, complete the corrective work.

Our assessments are clear enough for landlords, detailed enough for compliance records, and practical enough for maintenance teams to follow. We can support one-off assessments, ongoing monitoring, sampling, disinfection, plumbing changes, and planned maintenance. If a site needs testing, we explain why. If it does not, we say so. The goal is balanced advice. Competent, honest, and commercially sensible. For West London businesses, that makes compliance easier to manage and easier to prove.

Frequently Asked Questions
How often do I need a Legionella Risk Assessment in West London?
There is no fixed legal expiry date, but assessments should be reviewed regularly and whenever the system, usage, or occupancy changes. ACOP L8 compliance generally expects ongoing review, often every two years in practice. In high-turnover areas like Hammersmith or Fulham, landlords should also review between tenancies where access, use, or water conditions may have changed.
Is a Legionella Risk Assessment a legal requirement for West London landlords?
Yes. Landlords have legal responsibilities under the Health and Safety at Work Act 1974, COSHH, and wider safety laws to assess and manage legionella exposure. This applies to commercial and residential landlords, including a small office in Ealing or a single-room let. The Duty Holder remains responsible for keeping occupants safe.
How long does a West London site assessment take?
Most standard assessments take between half and one day, it depends on property size, access, and system complexity. Comfort Services Group plans routes across West London, including W, TW, and UB postcodes. That supports prompt arrival. The visit is designed to cause minimal disruption. To tenants. Staff. Daily business operations. We keep the process clear, organised, and practical. No wasted movement. No unnecessary delay.
What happens if my risk assessment identifies an issue?
Your report will include a clear Remedial Action Plan, ranked by urgency and practical next steps. You will know what the issue is, why it matters, and how to fix it. Comfort Services Group can also provide plumbing, cleaning, disinfection, or temperature correction services where needed, including dead legs, poor circulation, and system faults.
