Landlords and business owners in have a legal duty to assess and control the risk of Legionella bacteria in their water systems. Properties across the area often contain a mix of older plumbing systems, modern installations, communal water supplies, storage tanks, and infrequently used outlets that can create conditions for Legionella growth if not properly managed.
At Landlord Certification, our assessors understand the different water system configurations commonly found in residential and commercial properties. Whether your building uses a traditional hot water storage system, a communal supply, or a modern pressurised setup, we carry out a thorough assessment to identify risks and help you remain fully compliant with UK legislation.
Our assessors recognise these differences. We understand that a communal water system requires a different assessment approach from a modern pressurised hot water system, and that every property must be assessed according to its individual risk factors.
A legionella risk assessment is a structured assessment of your water systems to identify where conditions are present for the growth and spread of Legionella bacteria. Legionnaires’ disease is a severe type of pneumonia that can be deadly and is caused by Legionella pneumophila. It is very cold-tolerant and requires a temperature range of 20 to 45 degrees Celsius to grow, especially in systems with scale and/or biofilm formation, and in stagnant water.
All landlords renting property in Westminster must comply with the Health and Safety at Work etc. Act 1974 and COSHH 2002. This applies to single studio flats, family homes, large HMOs, and short-term holiday rentals. The duty is not conditional on property size.
Section 3(2) of the Health and Safety at Work Act makes provision for health and safety legislation to apply to landlords, ensuring a duty of care is shown to tenants regarding their health and safety. Under Section 53, landlords are regarded as self-employed and must conduct their undertaking in such a way that tenants are not exposed to health and safety risks.
Commercial properties face additional complexity. Offices, care homes, gyms, hotels, dental practices, and schools across Westminster all require assessment. Cooling towers, spa pools, and complex distribution networks demand specialist knowledge.
Employers must protect staff, visitors, and tenants. Our commercial service covers the full water system from mains entry to final outlet. We evaluate the competence of personnel responsible for water safety, the adequacy of control measures, and the effectiveness of monitoring regimes. For property managers with multiple sites, we offer portfolio-wide assessments with consolidated reporting and centralised record keeping.

Yes. It is a legal requirement for all landlords and employers in Westminster under UK law.
The Health and Safety at Work etc. Act 1974 places a general duty on employers and landlords to ensure health, safety, and welfare. Section 3(2) specifically makes provision for landlords to show a duty of care to tenants regarding their health and safety.
The COSHH Regulations 2002 require control of hazardous substances, including biological agents such as Legionella bacteria.
The HSE Approved Code of Practice L8 provides practical guidance on controlling Legionella in water systems. It has special legal status, if you are prosecuted for a breach of health and safety law and it is shown that you did not follow the ACOP, you will need to prove that you have complied with the law in some other way. If you follow the HSE guidance you will normally be doing enough to comply with the law.
HSG 274 Parts 1, 2 and 3 provide technical guidance supporting ACoP L8. Part 2 covers hot and cold water systems found in virtually every building and is the most widely applicable section for Westminster properties.

Yes, All landlords in Westminster must assess Legionella risk under the Health and Safety at Work Act 1974 and COSHH 2002. HSE ACoP L8 makes this duty clear.

No, Testing analyzes water samples in a laboratory. A risk assessment inspects the entire system for conditions that allow bacteria to grow. Testing is only needed when the assessment identifies a specific risk that warrants laboratory confirmation.
Same-week appointments are usually available. The on-site survey takes 45 to 90 minutes for domestic properties. Your detailed compliance report with photographic evidence and action plan is delivered within 24 to 48 hours of inspection.
Yes, only if you hold full competency in water system management and HSE ACoP L8. The HSE states that most landlords can assess the risk themselves and do not need to be professionally trained, but if they do not feel competent or inclined to do so, they can arrange for someone to do it on their behalf.
