Who this is for
Legionella.io is written for duty holders, responsible persons, facilities and estates managers, and the contractors who support them. The aim is narrow and practical: help you make sound decisions about real buildings and prove that your controls are working. The reader we picture is busy, mildly sceptical, and has already read three generic Legionella posts this morning. We try to give them the thing those posts did not.
How the articles are written
Every article is built around a specific angle and a clear reader, not just a keyword. Depending on the question, that might be a practical guide, a comparison, a troubleshooting walk-through, a cost breakdown, a myth-versus-reality piece or a step-by-step tutorial. The structure follows what serves the reader, which is why no two articles read quite the same.
Each one answers the main question early, gives concrete examples rather than platitudes, and ends with something you can actually do next.
Where the facts come from
Claims are tied to recognised UK and international authorities. We do not invent statistics, prices, specifications, dates or standards. Where a figure depends on your specific system, we say so and point you back to your own risk assessment rather than quoting a number as if it were universal.
- HSE. Approved Code of Practice L8 and technical guidance HSG274 / HSG282.
- NHS & NHS England. Clinical information and HTM 04-01 for healthcare premises.
- CDC. Microbiology, spread and laboratory testing.
- UKHSA. Outbreak investigation and surveillance data.
- BSI. BS 8580-1 (risk assessment), BS 7592 (sampling), BS 8680 (water safety plans).
Who publishes this, and how we keep it honest
Legionella.io is published by REMOTE TECH LTD, the company behind L8log, a Legionella compliance software suite covering risk assessment, remote temperature monitoring and digital logbooks. You will see those tools referenced on the site, always clearly labelled as coming from L8log and kept separate from the editorial guidance.
We are upfront about that because trust is the whole point. The advice here does not change to suit the software: the controls we describe (temperature, water movement, cleanliness, records) are the recognised UK approach whether you log them on paper, in a spreadsheet or in any product, ours included. Where a tool genuinely helps with a job, we will say so; where the honest answer is "you do not need software for this", we will say that too.
What this site is not
Nothing here is legal, medical or design advice, and it does not replace a competent, site-specific risk assessment. Legionella control is ultimately about your building, your water system and the people exposed to it. Treat these articles as a way to ask better questions and to understand the answers you are given, not as a substitute for professional judgement on your own premises.
