LCA Registered Legionella Risk Assessment Services Across the UK
The risk assessment is the first and most important part of any water management policy. It identifies where Legionella risks exist in your systems and provides the information needed to develop a written scheme of control, monitoring regime and remedial action plan.
The Testing Lab PLC (TTL) provides competent Legionella risk assessments for a wide range of buildings and water systems, helping dutyholders demonstrate compliance with HSE ACOP L8, HSG274 and BS 8580-1. Our team is LCA registered and experienced in complex, multi-site portfolios as well as individual premises.
Comprehensive Legionella risk assessments for water systems
Our risk assessments are designed to give you a clear, practical view of:
-
Where Legionella bacteria could grow or spread in your systems
-
How likely it is that people could be exposed
-
What controls are already in place – and whether they are adequate
-
What needs to change to reduce risk to an acceptable level
The assessment forms the foundation of your water safety / Legionella management plan and underpins all future monitoring, maintenance and record-keeping.
Why you need a Legionella risk assessment
UK health and safety law requires employers, landlords and those in control of premises to assess and control the risk from Legionella bacteria in water systems.
A suitable and sufficient Legionella risk assessment will help you:
-
Meet your legal duties as a dutyholder or landlord
-
Protect staff, residents, patients, visitors and contractors
-
Prioritise remedial works and investment
-
Avoid enforcement action, reputational damage and unnecessary disruption
Without a current assessment, it is almost impossible to know whether your existing controls are adequate – or whether you are leaving people at risk.

Frequently asked questions about Legionella risk assessments
Our Accredited Testing Services
Thank you very much for the air sampling results – and please accept our grateful thanks for resolving this issue so quickly and for the promptness of the report.
Your analyst, Lee, was very helpful and his suggestions and advice appreciated.
We would have no hesitation in recommending The Testing Lab and will be in touch soon with regards arrangements for a full asbestos survey for the rest of the site.
TTL have been working directly as my analyst for the last 12 months on a very complex asbestos removal scheme, they have achieved all of their KPI’s without fail and on a number of occasions surpassed their SLA in acting for us on planning issues associated with the demolition in regard to contamination which cannot be removed as part of the normal sequence of operation.
There reports are always issued within timescales and they have policed the reports by the Licensed asbestos contractor faultlessly sometimes in very difficult circumstances.
