Ensure you meet your health & safety obligations.  Legionella Risk Assessments carried out by Trust Mark Certified Risk Assessors from £75.00.

Having a Legionella Risk Assessment in place is for many people a legal requirement under Health & Safety law.  If you are a Landlord, Letting Agent, Employer or in charge of or responsible for a property and in some cases even if you work from home then you should have a Legionella Risk Assessment in place and carry out regular reviews.


Legionella Risk Assessments need to be carried out by someone who is competent to determine the possible risk from Legionella bacteria.  To remain valid a risk assessment should be renewed at least once every two years.  Simply not having a risk assessment in place could be seen by the courts as a breach of health & safety law.


Why does a risk assessment have to be renewed at least once every two years?  Put very simply, because things change.  The law or guidance may have been changed or updated, or things may have changed at your property.  The HSE's ACOP L8 is very clear and requires that risk assessments be renewed at least once every two years as a minimum or more frequently depending on the level of risk.  You also need to renew your risk assessment if there is reason to believe the current assessment is no longer valid.


What is the difference between "renewing" and "reviewing" the risk assessment?  Renewing a risk assessment involves going through the same process as carrying out the initial assessment.  Your risk assessment should also be regularly reviewed during the period the assessment is valid for.  A review may typically involve ensuring the assessment is still in date and that the recommended control & prevention measures are in place.  The review will normally be a part of a management or wider health & safety meeting and may only take a few minutes to complete.


The confusion between reviewing and renewing an assessment is often caused by assessors who do not fully understand the requirements of the HSE's 4th Edition ACOP L8.  It is for this reason the HSE require those involved in assessing, testing and the control and prevention of Legionella bacteria to be "competent".


The level of competence required for assessing the risk from Legionella bacteria will vary depending on the type of site and system being assessed.  For example, in a single small domestic rented property the level of competence required is relatively low and anyone with basic plumbing DIY skills may be able to carry out the assessment.  At sites where systems are more complex or open to the public the level of competence required is higher and will usually require the services of a specialist contractor with specific qualifications & relevant insurance.


At Water Wise our highly qualified and experienced team of risk assessors are some of the few in the UK to meet the Government Endorsed Trust Mark standard for Technical Competence.  Our service team are also members of the Chartered Institute of Plumbing & Heating Engineering, the Water Management Society, the Engineering Council, Water Industry Approved and Water Safe registered.  So you can assured that our team have the experience and technical competence that you need.  In line with the requirements of the HSE's ACOP L8 and BS 8580-1 our risk assessments are straight forward and easy to understand.  Unlike many of our competitors the control and prevention advice we give in our risk assessments is not just an extract from the ACOP L8, the advice we give is specific to the site being inspected.

Our Risk Assessment Service


Each risk assessment involves one of our team calling to your property, carrying out a physical inspection, inspecting control & prevention records, assessing any training requirements, carrying out water testing (if required) and completing a written Legionella Risk Assessment based on the findings of the inspection.


We carry out three types of risk assessment as well as offer a DIY service for Landlords;


"with testing" water should be tested at least on an annual basis (if it is required), as a part of the risk assessment we can take water samples to be tested by a UKAS Accredited Laboratory.

"without testing" we can carry out a risk assessment without water testing, but you should make alternative arrangements to test your water if required.

"representative" section 2.146 of the ACOP allows for a representative risk assessment to be carried out for housing associations, local authorities and landlords who control several properties of similar design.  Please email us for more details.


The cost of a Risk Assessment starts from £75.00 +VAT based on a Domestic Property.

Our DIY Risk Assessment Service is £15.00 +VAT per Assessment
