Legionella Advice for Landlords

There has been a lot of confusion over the last few years about domestic rented properties needing a Legionella Risk Assessment and indeed if one is needed at all.  In brief, all rented properties domestic or not need a Legionella Risk Assessment but, you DO NOT need to pay hundrends of pounds to have one carried out.  The confusion is due to a misunderstanding of the requirements of the ACOP L8, the actions of several letting agents and Landlord groups. 


The Health & Safety Executives "Myths Buster Challenge Panel" issued their findings on this subject under case number 357 where the decision was reached that some consultants and letting agents were misinterpreting landlords responsibilities and an placing unnecessary financial burdon on landlords. 


At Water Wise Services we offer two types of Legionella Risk Assessment for Landlords.  Our cheapest option is our DIY service charged at £15.00+vat per assessment, the service allows Landlords to carry out their own risk assessments supported by our Trust Mark certified team, see our "DIY Assessment" page for more details.  Or, if your in an area that we cover and you are uncertain about doing your own risk assessment we can arrange for one of our assessors to carry out the risk assessment for you from £75.00.

In 2013 the 4th Edition of the ACOP L8 was released.  Previously to the 4th edition there was an artificial 300 litre volume limit for hot & cold-water systems which effectively excluded domestic rented properties from the ACOP L8.  The limit existed because it was felt that there was little to no risk of Legionella developing in smaller water systems.  The 4th edition of the ACOP L8 removed the artificial 300 litre limit and for the first time brought smaller domestic systems under the scope of the ACOP L8.  This was done because research has shown that Legionella can exist and grow in smaller water systems.  In support of the change the HSE released a document called "Essential Information for Providers of Residential Accomodation".


The requirements are simple.  You need a Legionella Risk Assessment carried out and reviewed at least once every two years by someone who is competent to assess the level of risk posed by Legionella bacteria.  After the risk assessment further action including Legionella Testing may be required.


You DO NOT need to test for Legionella every year unless the risk assessment has identified a need for testing.  You DO NOT need to produce a Legionella Test Certificate unless the risk assessment has identified a need for testing.  You DO NOT need to renew, review or carry out a new risk assessment every time there is a tenancy change.


Under the Housing & Planning Act 2016 councils can now issue a Civil Penalty against Landlords & Letting Agents of up to £30,000 for not meeting the required housing standards including Health & Safety.  The Civil Penalties were introduced in April 2017 as an alternative to councils bringing criminal prosecutions.  Local Authorties are then allowed to keep the fines.  Some authorities are also considering introducing licensing schemes under the new legislation.  The act also allows for councils to issue Banning Orders & Rent Repayment Orders.  There is no limit to how many fines can be issued and Landlords & Lettings Agents could be hit with multiple fines at the same time.  Under Health & Safety law Landlords can be fined for simply not having a Legionella Risk Assessment in place.

  The Confusion About Legionella Risk Assessments


The confusion occured because of letting agents who contacted landlords advising them that they have a legal or statutory requirement to test for Legionella which is not the case.  This has been an industry wide problem because of misinformation given to letting agents through their governing and training bodies.  The way this information has been presented has led letting agents to believe that a test certificate is needed in the same way a Gas Safe certificate is needed.  There is NO automatic or legal requirement to test for Legionella unless identified by the risk assessment. 


In response landlord groups such as the NLA replied (through press releases etc.) that there is no need for landlords to do anything and that nothing has changed.  Again, this is not correct as there had been a documented change, domestic rented properties are now under the scope of the ACOP L8.  However, landlord groups were addressing the claim that landlords need to test for Legionella and did not make it clear that a risk assessment is now required.  Prior to the release of the 4th edition in 2013 domestic rented properties did not need a Legionella Risk Assessment.


The comment is often made that nothing has changed because the law has not changed.  It is correct the law has not changed but the ACOP L8 is not a law, it supports the requirements of other laws in relation to Legionella.  The Code of Practice has a special legal status.  If you are prosecuted for a breach of health and safety law, and it is proved that you did not follow the relevant provisions of the Code of Practice, you will need to show that you have complied with the law in some other way or a Court may find you at fault.

A Written Legionella Risk Assessment


To assess the risk correctly a physical inspection of the hot and cold-water system needs to be carried out and measured against the performance criteria of the ACOP L8.  A risk assessment needs to be written based on the inspection.  There are some claims that a "written" risk assessment is not needed and you only need to show you have "considered the risks" of Legionella.  Whilst this is partly true we must also consider that if there is an outbreak of Legionnaires Disease how does a Landlord show they have considered the risk of Legionella?  The answer is simple, it is proved by a 'written' and "dated" Legionella Risk Assessment.


To carry out a Domestic Legionella Risk Assessment you need to be competent to assess the risk.  This means that Landlords can carry out their own risk assessments if they feel they are technically competent.  There is an issue with this as the HSE do not state what " technically competent" means in terms of Legionella and Landlords could leave themselves liable if they do not assess the risk correctly.
