Hello This type of thing has been asked for before so it may be worth searching the forums. However we will not have a generic assessment for you to see, each will be specific (or cloned) and relate to the system in place

If you are a landlord renting a flat or house out, it is domestic premise for tenants, but las landlord you have legionella duties! Various websites have info. for private landlords. Typically advise the lease should require the tenant to clean the shower head and annual temp. checks by landlord. As a local authority we have sheltered housing, Ie tenants have own their own rented accomodation in block of several with somecommon areas.. Each unit is domestic for tenant but LA as landlord has legionella control duties. Fun and games when legilonella is backtracking from tenants private accomodation into common supply. Yes we do organise with tenants cleaning shower heads for them. Housing associations often have similar problems.

Bob, I would expect a plumbing company to have an RA for plumbing work done in people's houses, e.g. refurbishing bathrooms and ripping out shower units, where there might be a risk of water spray from old pipes containing water under pressure.

In domestic premises, no dead legs, no long runs where the hot water temperature can drop, water is run all the time, combi boilers in most modern homes, no infrequently used outlets, most people are fit and well, etc... Just had a look at my own house. Deadleg 20ft to disconnected fridge water cooler. Old water to Kitchen runs above hot water pipe - mean cold water temp 24 deg.c. Outside tap - not used in autumn and winter. Conventional boiler / HWST with CWST header to boiler (in loft at 29 deg - Mid Nov). Occupier is overweight middle age male with history of respiritory disiease. Sin summer the paddling pool sits for a week or two at a time. Hose sits soaking up the sun in between (infrequent) watering of gardens. I don't think domestic premises are nessessarily lower risk. But probably less likely that respiritory infections affecting 1 person -(rather than a group) are likely to get the diagnosis and so don't get into stats. I expect many cases of Lochguilhead feaver are misdiagnosed as flu. By the way - I've corrected the issues in my own house now (except I'm still overweight). C.G.

With all due respect this law as per other H&S law does not apply to a domestic premises par say and I am sticking to my guns ------------------- However the law applies to somebody at work in a domestic premises where they are likely to interface with a legionella hazard which is a different matter to the bland statement that legionella applies to domestic premises e.g. the law does not apply to the person sitting in their own home watching telly either as an owner or tenant [unless the tenant has a specific duty written into their tenancy agreement which is highly unlikely] but does apply to a plumber/plumbers employer where they are at work in a domestic premises and to a landlord who has formal duties Interestingly the law has not yet been tested on stand alone none charity volunteers where the volunteer, who is not at work, undertakes free activities in a school which they do at present or a sheltered housing situation --- I have queried this with the HSE on many an occasion over many years but no satisfactory answer has been forthcoming where the volunteer is not part of a formal charity As far as I am aware the HSE/EHO's have no right of entry under any circumstances to a wholly domestic premises e.g. my / your house. They may enter the common areas of a place of multi occupation that is run as a business e.g. block of flats but have no right to go into a personal bedroom/lounge etc. in that place. Where a worker has been killed whist working in a private house or private bedroom of a tenanted house/house of multiple occupation that is a business the HSE may enter the wholly domestic part e.g. bedroom etc. of the premises under the powers of the police with restrictions but not under their own powers ---------- friends please correct me if I am wrong as I am now old and my memory is not what it was but my comments do come from my friends who were very high up in the HSE Interestingly environmental law technically applies to me/you as an individual in our private homes e.g. burning burning rubbish etc. in our private garden great debate site this is it not?
