Management of water systems to ensure control of Legionella comes from Control of Substances Hazardous to Health regs and H&S at Work Act. L8 is the ACOP that provides information on how to manage water systems to maintain safety. I work for a Social Landlord and we have many water risk assessments and control measures including sentinal temperature monitoring and sampling. We are currently reviewing the processes to ensure that we follow the new L8 guidance Hope this helps

Sorry I didn't make this clear, but I am talking about landlords of private houses, not landlords of work premises. Is this legislation still relevant?

Not applicable in private dwellings. Unless the tenant is being cared for by a care provider, now H&SAWA applies, their is also a good chance that if they are receiving care they may fall into the category of vunerable people. This applies more so where the private dwelling is a House of Multiple Occupancy (HMO).

One of the FAQs' on this topic from HSE website is:- As a landlord, what are my duties? Refer to:- http://www.hse.gov.uk/le...naires/faqs.htm#Landlord

The dwelling may be a private abode but the landlord is still running a business so they have statute and civil law landlord duties to adequately maintain on behalf of their 'private' tenants However as a landlord myself in the past I did not go as far as carrying out legionella nor other types of tests inside the private home nor have what could be seen as a formal legionella management system and the local council was more than happy with this approach and as far as I am aware an average landlord with average tenants in single house accommodation does not have a specific legal duty to manage legionella as one would do in a work situation or similar as already noted in the same way as fire and other areas noting that this is a private persons home Talk to your local EHO's/Building control dept (if such things still exist noting the current cuts!!) as they should be able to give more up to date advice but I doubt if the local council would be too bothered with a situation you describe and this is probably outside the HSE's remit

What Bob says. Making money from renting out property is a business thus HASWA applies. However, for the love of all that is good in the world, don't go mad. Keep everything in proportion - a 'normal' house with constant occupancy is very likely to be low risk. HSG274 Part 2 talks about making checks at the same time as other statutory checks such as gas appliances i.e. once a year.
