GCC’s in-house Legionella Compliance services will give you the peace of mind and formal documentary backup to ensure that your hot and cold water systems are fully compliant with:

GCC Engineers are well versed and up to date with the following guidance set out by the Health and Safety Executive (HSE), British Standards Institution (BSI) and the NHS. We can ensure that your water systems are maintained to standards compliant with the following legislation and regulations:

Delivered by GCC’s specialist in-house teams, Legionella Compliance services can be part of a wider Hot and Cold-Water System Management contract or delivered as a standalone service.

Shower-heads and other dead-legs are cleaned and disinfected quarterly (or more frequently as required) using chemicals with proven biocidal efficacy against Legionella bacteria in accordance with GCC’s task-specific Risk Assessment & Method Statements (RAMS).

The service can also be bunded with other maintenance activities including cold water tank inspections and remedial repairs, periodic steam, carpet & upholstery cleaning to deliver added value.

Remote Monitoring

GCC can automate temperature checking using permanent, on-site monitoring and data-acquisition sensors supported by offsite data analysis and alarm functionality. 24/7 monitoring provides a far more thorough overview of a hot and cold water system. This also allows trend analysis that can identify potential failures before they occur.

Contact GCC to request further details and a demonstration of the system.
