Your Water Hygiene Logbook

Ask most building managers about their water hygiene logbook and you will get one of two answers. Either it is kept up to date and filed neatly, or there is a slightly awkward pause.

If you fall into the second camp, you are not alone. Record keeping is easily the least exciting part of water tank maintenance. But when an auditor, insurer or health inspector comes knocking, your logbook is the first thing they will ask for. Here is what it should contain and why it matters more than you might think.

Why a Logbook Matters

Under the HSE’s ACOP L8 guidance, anyone responsible for a water system must be able to show that risks are being managed. The key word is show. Doing the work is not enough on its own. If it is not written down, as far as an inspector is concerned, it did not happen.

A well kept logbook proves your maintenance routine exists. It protects you if something goes wrong, supports insurance claims, and makes handovers far easier when staff change or a new contractor takes over.

What to Record

Your logbook does not need to be complicated. It needs to be consistent. Here is what should go in it:

• Monthly water temperature checks, including the date, outlet and reading
• Tank inspections, with notes on condition and any defects spotted
• Cleaning and chlorination work, including certificates from your contractor
• Water sampling results and any follow-up actions taken
• Repairs or alterations to the system, however small
• Your written risk assessment and the date it was last reviewed
• Details of who carried out each task

Each entry only takes a minute or two. The habit matters far more than the format.

Paper or Digital?

Either works, as long as it is kept up to date and easy to find. A simple ring binder in the plant room has served buildings well for decades. Digital records have the edge for larger sites, since they are harder to lose and easier to share with contractors and auditors.

Whichever you choose, keep records for at least five years. Inspection findings in particular may be needed long after the work was done.

The Most Common Mistake

The biggest logbook failure we see is not missing paperwork. It is gaps. A logbook with six months of tidy entries followed by a year of silence raises more questions than no logbook at all, because it shows a routine that was started and then abandoned.

If your records have lapsed, do not be tempted to backfill them. Just start again from today and keep going. A consistent record from this point forward is worth far more than a patchy history.
