We cover Derby. We are Leeds-based, about 85 miles away, and we plan each visit in advance and group sites together. Patients and residents are more vulnerable to infection, so the standard for water safety in healthcare premises is higher. If you manage a hospital, surgery or care home in Derby, can you show that your water systems are under control?
Water Hygiene Services is an independent water hygiene company based in Leeds, about 85 miles from Derby. We carry out Legionella risk assessments, monitoring, sampling, remedial works and recommissioning for healthcare premises in Derby, to HSG274 and HTM 04-01, working alongside your Authorising Engineer and Water Safety Group. The legal duty sits with the duty holder under ACoP L8.
HTM 04-01, Safe water in healthcare premises, is the Department of Health guidance on hot and cold water systems in healthcare buildings. For the full explanation, see our Healthcare page.

What temperatures apply in healthcare premises?
HSG274 Part 2 and HTM 04-01 give the figures we check against. Legionella grows between about 20 and 45 degrees Celsius, so the aim is to keep water outside that range.
- Hot water stored at 60 degrees or above
- Hot water at outlets at 55 degrees or above within one minute in healthcare premises
- Cold water below 20 degrees within two minutes of running
- Thermostatic mixing valves checked and serviced to protect vulnerable users from scalding while hot water stays hot enough

Questions we are asked in Derby
Do you need to work with our Authorising Engineer?
Where you have appointed an Authorising Engineer (Water), we work to their requirements and give them the information they need.
Is the legal duty the same for care homes as for hospitals?
The duty to assess and control the risk applies to both. The level of risk and the controls differ, because of the vulnerability of the people in the building. Your risk assessment sets what is needed.
Can you work around wards and clinical areas?
Yes. We agree access, timing and any isolation with your estates team before work starts.
What records do we need to keep?
The risk assessment, the written scheme, monitoring and flushing logs, temperature records, cleaning and maintenance reports and sampling results. We keep these up to date for you.
Do you cover Derby?
Yes. We cover Derby and agree the scope and timings with you in advance.
