Legionella Schematic Drawing


Legionella Schematic Drawings form an integral part of any legionella control and management programme and are specifically required by the HSE’s guidelines – HSG 274 Part 2. The legionella schematic drawings may be a simplified but accurate diagram that identifies the water system assets and equipment components.

Legionella schematic drawings should be easy to read without the need for specialist training or experience. Legionella schematic drawings should also include all temporary fittings are present within the water system. For instance, a temporary washing machine that is only intended to be installed for a short period of time should still be incorporated within the schematic as it will directly impact the water systems water quality in not managed correctly.

If you have already had a legionella risk assessment or legionella monitoring carried out in the past, the chances are you have a legionella schematic drawing. We understand that you may have already carried out a legionella risk assessment, legionella sampling, or a legionella schematic drawing. This is why uRisk provides all legionella services independently to tailor to your requirements. This helps to make our pricing the most competitive in the industry for water hygiene and legionella services.


Why do I need a legionella schematic drawing?


A schematic drawing will help display the layout of your water system and will help you to identify risks and monthly temperature points (sentinel points). Key problem areas can be easily be identified and assists engineers in undertaking remedial works and water disinfections when removing any bacteria present.

When and how often do I need a legionella schematic drawing?


An indication of when to review the schematic:

  • A change to the water system;
  • A change to the use of the building where the system is installed;
  • New information available about risks or control measures;
  • The results of checks indicating that control measures are no longer effective;
  • A case of legionnaires disease.”

We recommend annual reviews to ensure correct implementation is being carried out. Legionella bacteria can double within 15 minutes, so it is important to review your report and monitoring records regularly.

How much does a legionella schematic drawing cost?


Legionella schematic drawings vary in price depending on the number of water outlets, cold water storage tanks, hot water cylinders, combi boilers and other water assets that may be present. The number of assets within your water system will determine the time spent on site and how long it will take to produce your schematic.

So how much does it cost? Schematic drawings range from £50 to £500. Prices vary enormously often depending on the size of the company you use, their processes, the software and detail used. Most legionella schematic drawings take between 1-3 hours to produce. uRisk provides legionella schematic drawings from £50 for small to medium sites to £100 for sites large sites with over 200 outlets and assets.

How long will the legionella schematic drawing take?


On average, schematics are drawn within 1-3 hours. These are then sent at the same time as your legionella risk assessment and any other documentation.


When will I receive the legionella schematic drawing?


You will receive your legionella schematic drawing between 2-10 working days from the date of the site visit. From time to time, not often, our team will need a little more time, so please expect to have your report no later than 30 days. Need your schematic drawing sooner?

What do I do after the legionella schematic drawing?


Once you have received your drawing you should keep it within your water logbook. It should be kept as your live schematic drawing until you have any new works undertaken on your water system. You will then need a new up to date schematic to replace the out of date drawing.
