Legionella Risk Assessment & Legionella Legislation Compliance Across the UK

A legionella risk assessment is the essential first step in identifying hazards within a water system and determining how to reduce the likelihood of legionella developing. As an LCA-registered provider, we ensure every assessment is carried out to recognised standards, giving duty-holders confidence that their water systems are being managed correctly.

Every water system in England, Scotland and Wales is unique. From the point where water enters a building to the assets that use or store it—taps, showers, sinks, water heaters, cooling towers, evaporators and more—each component can influence the potential for legionella growth. Because no two systems are the same, each must be assessed individually.

When managed properly, legionella risks can be significantly reduced. A comprehensive risk assessment examines all parts of the system, including pipework, storage tanks, thermal mixing valves (TMVs), sentinels, intermediate outlets and all connected assets. This process enables us to create a tailored management plan that keeps the water system safe, compliant and well-controlled across England, Scotland and Wales.

This must be an absolute record for getting a report back, considering the surveyor arrived around 3pm – very well done!

Thank you for offering such a prompt turnaround for ACM testing and for your courteous service in doing so – I had a nervous client to placate and knowing the report would be back with them in such a short time was very reassuring to them, and for no more than a basic service from the competition!

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.
