Legionella in Properties

All landlords have a legal responsibility to ensure the health and safety of their tenants. This means taking necessary measures to control the risks from hazardous biological substances which includes legionella.

The risk of legionella is considered to be quite low in residential properties because of the regular water usage. Landlords do not need to be trained or accredited to assess the risks themselves, but it is a good idea to keep records of all assessments and actions for insurance purposes.

If tenants report problems with the hot water not heating properly, or there is any problem with the water system, action needs to be taken to fix the problem as soon as possible and prevent the possibility of legionella being able to grow.

Properties that are left empty for any period of time should be carefully managed to avoid the risk of water stagnation. Hot and cold systems should be used at least once a week to keep the water flowing, and if the property is going to be vacant for a long period, it is a good idea to drain the system completely.

Whilst landlords can carry out their own assessment, some opt to use our professional services to be on the safe side and to ensure all areas of risks are assessed.

Legionella Risk Assessment for Landlords FAQ’s

If any of your legionella risk assessment for landlords questions are left unanswered. Then head to our Legionella FAQs page or contact our friendly team today.

Do all landlords need legionella risk assessments?
Yes, ACOP L8 states that “2.138 – Landlords who provide residential accommodation, as the person in control of the premises or responsible for the water systems in their premises, have a legal duty to ensure that the risk of exposure to the tenants to legionella is properly assessed and controlled.”

ACOP L8 also shows that “2.140 All water systems require a risk assessment but not all systems require elaborate control measures.”

What do estate agents and lettings agents need to do?
ACOP L8 states that “2.139 – Where a managing (or letting) agent is used, the management contract should clearly specify who has responsibility for maintenance and safety checks, including managing the risk from legionella”
How much does a legionella risk assessment for landlords cost?
Domestic legionella risk assessments can range tremendously with a number of plumbers, gas engineers and other tradesmen offering these assessments without the specialist training, it’s important to check that your assessor or engineer is properly qualified. Here at uRisk our prices start from £55 for multiple landlord properties to £95 for single landlord properties. Our prices for residential rental properties are based on the property being no more than 5 bedrooms.
How long will the risk assessment take?
Legionella Risk Assessments for Landlords on average take between 15-45 minutes depending on the size of the property.
Things to do before your legionella risk assessment visit...
Please ensure that all areas of the water system are easily and safely accessible. In particular, cellars and loft spaces, they must be well lit, boarded of conditions to a level that satisfies the assessor on the day of site attendance.

Should the levels of health and safety be insufficient for the assessment, a second visit will be necessary, after the safety measures have be implemented. Additional fees apply for further visits – terms & conditions apply.

Are landlords properties actively inspected?
According to the Health & Safety Executive – “HSE and Local Authority inspectors do not proactively inspect domestic premises or ask for evidence that landlords have undertaken a risk assessment”.

However, “if a tenant were to contract Legionnaires’ disease from the water system in their home, the landlord may be liable to prosecution under HSWA, and would have to demonstrate to a court that they had fulfilled their legal duty, so it is important that they assess and control the risks”.

What happens if I decide not to have a legionella risk assessment?
The consequences of not complying with ACoPs L8 are serious. As a landlord you are legally required to manage properties so that tenants, residents, and/or visitors are not exposed to risk.

Heavy fines and even imprisonment can be imposed especially in the worst case senario of death. You may also be prosecuted should there be an exposure to risk, without necessarily anyone becoming ill.

How often do I need a legionella risk assessment for landlords?
ACOP L8 stats that “2.140 It is important to review assessments periodically in case anything changes in the system”

What remedial works you might expect to do?
What is a Flexi-Hose?

Flexi-hoses are often used by plumbers to connect copper pipes with taps when it is difficult to fit the copper pipe directly into the tap.

Legionella bacteria is known to feed and grow from a number of sources including materials. Where copper pipe provides a limited source of food, flexi-hoses are quite the opposite. In particular, non WRAS approved flexi-hoses are often made of more susceptible material that deteriorates quicker than those that are WRAS approved.

What Insulation do I need?

Where the report highlights that your water system requires insulation it is referring to 3 types: Cold Water Storage Tank Insulation, Hot Water Cylinder Insulation or Pipe Insulation. You can find where you need the insulation in Section 4 of your risk assessment.

The purpose of the insulation is to prevent heat loss or heat transfer; this aids the prevention of bacterial growth by keeping temperatures within recommended range.

What is a Bye Law 30 Kit?

A Bye Law 30 kit consists of two screens which act as a mesh to prevent foreign bodies entering the tank. One screen is fitted to the overflow pipe, and a second to the tank air vent.

What is a Tank Inlet (Mains) Re-route?

Often, the inlet (water pipe entering the tank) and outlet (water pipe leaving the tank) are installed on the same side. This leads to stagnation on the opposite side of the tank and ultimately provides suitable conditions for legionella growth. The inlet and outlet should be opposed to create a cross flow of water which limits stagnation/ still water.

Is it best to remove my Cold Water Storage Tank (loft tank) completely?

In terms of bacterial growth, yes! By removing items that store water you are removing areas prone to stagnation.

What is a Dead Leg/ End?

A dead leg is a length of pipe that leads to an outlet (sink, shower, etc) but is rarely used. A dead end is a length of pipe that has been capped off and does not allow water to flow. Both cause stagnation and create the condition for contamination.

Caution Hot Water Signage

Due to the recommended temperature ranges, hot water is within scalding risk range, it should therefore be considered that hot outlets are labelled accordingly. Alternatively, tenants should be made aware of the control measures in place including scalding temperatures.

Simple control measures to reduce the risk of legionnaires disease…
Simple Landlord control measures:

  • flushing out the system prior to letting the property
  • avoiding debris getting into the system (e.g. ensure the cold water tanks, where fitted, have a tight fitting lid)
  • setting control parameters (e.g. ensure water heater is set to 60°C)
  • make sure any redundant pipework identified is removed
  • cold temperatures remain below 20 degrees and hot reach taps at 50 degrees.

Advise your Tenants:


  • of control measures put in place (e.g. not to adjust water heater from 60 degrees)
  • to regularly clean shower/ tap heads
  • to inform the landlord if the hot water is not heating properly
  • to update the landlord with system problems so that appropriate action can be taken.
