Water is a basic necessity required for almost everything and the maintenance and hygiene of water systems is essential to ensure the health, safety, and wellbeing of those who use it. If not properly maintained, water systems have the potential to become breeding grounds for bacteria, and users or those in the vicinity can be exposed to diseases that are extremely harmful and potentially fatal.

At Comfort Services Group we deliver a wide range of professional water hygiene and treatment services designed to meet your systems specific needs and ensure that your water is clean, safe, and complies with the latest regulations and health and safety guidelines.

Safe Water Systems

In our line of work, we are more than aware of the potential dangers, harm and risk that can come from improper, poor or irregularly maintained water systems. Cold water storage tanks, hot water storage cylinders, pipework and distribution systems should be regularly inspected, tested, disinfected and cleaned to ensure that any dirt or contaminants that have built up are removed to prevent them from affecting the quality of the water. 

“The team at Comfort Services Group were awesome when they carried out the Legionella Control works at our offices, they were very accommodating, Tom and the guys on site were a pleasure to work with. I would recommend the services of Comfort Services Group without reservation. Excellent First impressions with the Office Team, which was mirrored by the guys who did the work. Thanks guys.”


When a new installation or extension of pipework is made to an existing system it is essential that this is cleaned and disinfected thoroughly to prevent any contaminants from being introduced to the water.

Our team of qualified engineers have years of experience working on a wide range of water systems including drinking water supplies, domestic hot and cold systems, showers and more. All of these types of systems can produce fine water spray or aerosolised water particles which can be inhaled and cause severe illnesses such as Legionnaires disease, which is why regular testing, treatment and maintenance is crucial.

Frequently Asked Questions

The term ‘Water Hygiene’ refers to practices, treatments and services that preserve and maintain the health, cleanliness and hygiene of water supply systems such as drinking water and domestic hot and cold systems.

Any of these applications can potentially generate aerosolised water spray which can be inhaled and lead to harmful illnesses such as Legionnaires disease which is a potentially fatal form of pneumonia that everyone is susceptible to infection from and even once recovered can cause long term health issues.

The law states that landlords, property owners, employers any persons in control of a premises have a legal responsibility and obligation to ensure that occupiers, residents or workers within their premises are suitably protected from water safety risks such as Legionella. This means that as the person responsible you are accountable, and it is your legal duty of care to maintain the cleanliness and hygiene of water systems at all times.

With a strategic, consistent approach to water safety, we can help to prevent and control the risks of potential bacteria within your water system and provide detailed records which can be kept as proof of compliance.

It is crucial that all necessary steps are taken to ensure that the water system is managed correctly with a nominated person responsible for this key health and safety duty who can identify potential issues and liaise with professional water hygiene services to review, asses, treat and maintain the water system.

Monitoring the system through regular water testing can be key in ensuring the integrity of the water and identifying any potential issues such as corrosion, contaminants, bacteria and scale at the earliest stages. If regular testing reveals a problem, then water hygiene experts can provide the professional, reliable treatments required to ensure that the water is safe and your organisation meets its legal obligations.
