About your Legionella risk assessment

Easy to understand - Highlights the risks - Provides recommendations

Our risk assessments meet the requirements of the ISO: 9001 standard. We complete them in line with the HSE’s Approved Code of Practice (ACOP) L8. This provides you with the assurance that your risk assessment will be comprehensive.

Our Legionella consultants will assess the risks of Legionella bacteria at your premises. They will examine a range of factors in this process including:

  • Your water system and its design. For example, we will identify dead legs. These can allow for water to stagnate and allow microbial growth.
  • The usage rates. Low use can lead to bacteria growth.
  • The temperature of your water system. This is important as Legionella bacteria grows in water systems between 20 degrees Celcius and 45 degrees Celcius.
  • The bacteria levels within your system. We may take samples to test for total bacteria levels within your system but with a focus on Legionella.

We enter the results of the risk assessment into our database on site. This improves the accuracy of our work. It also reduces the lead time on the provision of your risk assessment document.

Once we have identified the risks, we will look at each one in detail. Then we provide tailored recommendations to minimise each risk. You may need some modifications to the system design or the temperature may need adjusting. We could advise you to flush and clean elements of your system on a regular basis. It is highly likely you will need to implement on-going monitoring.

How long will a risk assessment take?

Electronic data input on site delivers quick, efficient and accurate risk assessments.

We have a multi-skilled team of consultants throughout the South West and a management team ready to assess your individual site. We are well placed to be able to attend site quickly and at a time convenient for you.

The time needed on site depends on the size of your building. Your quotation will confirm clear time frames that our team will carefully manage.

We have outlined an example project plan for a typical GP surgery below.

Day 1 - Our consultant will spend half a day at your site for the practical assessment.

Day 2 - Our consultant will write your report and arrange for the production of any required CAD drawings.

Day 3 - Our consultant will finalise your report. Then, following a quality check, we will email your risk assessment and make it available on your customer portal.

How much does an assessment cost?

Bespoke prices for each individual site.

Every site is unique in size, location and, therefore, requirements. As a result each building will need a different number of man hours on site.

Our MD, Dr Tim Hamilton will discuss you site with you in great detail. This ensures that we provide an accurate, fixed cost quotation.
