Yes. If you are a commercial enterprise of any kind then you are legally required to have a Legionella risk assessment in place and be completing satisfactory controls. This includes private landlords.
The guidelines state that there is no set period a Legionella risk assessment should be reviewed. However, if there are any changes to the system design, building use, designated responsible person or the controls are inadequate then the risk assessment should be reviewed. There might also be a recommended review date if the risk is higher i.e. in healthcare where the susceptibility level is higher.
Someone with suitable training and knowledge that understands how Legionella can proliferate in a water system can complete a Legionella risk assessment. For very small mains fed systems using combi boilers it may be possible that a duty holder with some basic training and awareness can complete a Legionella risk assessment, however where systems become more complex a professional would be required. PHX Water risk assessors are Water Management Society and City & Guilds accredited.
HSE guidelines state that cold water storage tanks should be inspected annually and hygienic conditions recorded. Based on this inspection, remedial works may be required such as cleaning and disinfection.
Based on the annual tank inspection, the hygienic condition of the water tank may show that cleaning and disinfection is required. There is no set period a system should be cleaned and disinfected however if a system is prone to fouling / sedimentation then a cleaning regime may be recommended. At pHX Water, we use internationally recognised products to clean and disinfect any potable water tank.
UV sterilisers are an excellent non-chemical solution to achieving disinfection. They are easy to use and maintain. They are also a reliable source of disinfection for private water supplies, so long as suitable pre-filtration is installed (usually a minimum of 5 micron). It’s important to follow manufacturer guidelines for replacement consumables such as UV bulbs and quartz sleeves as failure to do so can result in a loss of effectiveness and active bacteria passing into your water system.
Generally, if you are on a mains water system you won’t require any filtration as the water is treated by Scottish Water. However, you may be interested in point of use (POU) filters to remove chlorine or reverse osmosis systems for use in healthcare premises such as dental practices. If you are on a private water supply then you will require a filtration setup to remove contaminants found in the water course. This may require multiple cartridges, each capable of filtering different contaminants before making the water suitable for drinking. Consideration should be given to installing disinfection equipment (either by UV or chemical) downstream of the filtration setup.
Yes. There are grants available for improvements to private water supplies in Scotland. The amounts can vary but for up to date information, check out the link on the government website for more information.
We can also assist with the supply and installation of necessary equipment.

"We used PHX Water for a number of their services throughout multiple sites across our group, from Legionella risk assessments, tank cleaning and water sampling the service was excellent and we would highly recommend using pHX water. Thanks to the pHX Water team for all your help making this process so efficient and easy to understand."
"We used the pHX Water team to carry out a legionella risk assessment for our hospitality business. Their approach was very professional and incredibly quick to respond. They took care of all the laboratory testing and now performs routine checks to keep us within our legal requirements as business owners. We’ve been left with a file for all the documentation all properly organised so it really is a turn-Key service. I would have no hesitation in recommending pHX Water."
“I had PHX carry out a replacement water filtration system at a rural property outside Stirling that was serviced by a private supply. Very knowledgeable staff and prompt service. Would highly recommend them”
