Log books & compliance records
Every check, result, clean and action, recorded in one place and kept up to date. So when an inspector or insurer asks, you can show them in minutes.
If it isn't written down, it didn't happen.
ACOP L8 expects the dutyholder to keep records of the risk assessment, the written scheme, and the results of monitoring, inspection, testing and checks. Monitoring records should be kept for at least five years. In practice, the log book is often the first thing an inspector asks to see.
We set up a log book that's laid out logically, then update it on every visit: dip slide and chemistry results, lab certificates from the UKAS-accredited lab, cleaning and disinfection certificates, dosing equipment checks and any corrective actions with the date they were closed out.
We'll also make sure your notification under the Notification of Cooling Towers and Evaporative Condensers Regulations 1992 is on file. More on that in our article on notifying the local authority.

Log books & compliance records: common questions
How long do cooling tower records need to be kept?
ACOP L8 says records of monitoring, inspection, testing and checks should be kept for at least five years. Records of the risk assessment and written scheme should be kept while they're current and for at least two years afterwards.
Can records be kept electronically?
Yes. ACOP L8 doesn't insist on paper. What matters is that the records are complete, accurate, easy to find and can't be quietly altered later.
We've inherited a messy log book. Can you help?
Yes, that's a common one. We'll audit what's there, tell you what's missing and set up a clean structure going forward.
Who should sign off the log book?
Entries are made by whoever carried out the work. The responsible person should review the records regularly and make sure actions are closed out.
