The bottle's still full. It's sat by the keyboard since nine, through two meetings and a stretch of emails, and it's four o'clock before anyone notices it hasn't moved. Nothing about that breaks any rule.

The Law, Stated Plainly

Under Regulation 22 of the Workplace (Health, Safety and Welfare) Regulations 1992, every employer in Great Britain has to provide "an adequate supply of wholesome drinking water" for everyone at work, "readily accessible at suitable places." If it doesn't come straight from a tap or a drinkable jet, there has to be a cup or vessel to drink from instead. This has been a standing legal duty since 1992, not an optional courtesy, and it's enforced by the Health and Safety Executive like any other workplace welfare requirement.

What the Law Doesn't Cover

Read the regulation again and notice what's missing. It says nothing about how much water is enough, how often anyone should drink it, or what happens across a working day between the tap being accessible at nine and a bottle still being full at four. Access is the duty. The rest is left entirely to the person holding the bottle.

What Public Guidance Adds, and Where It Stops

The NHS puts general adult fluid guidance at 6 to 8 cups or glasses a day, counting tea, coffee, and lower-fat milk alongside water. The European Food Safety Authority's own reference figure runs a little higher: an Adequate Intake of roughly 2.5 litres of total water a day for men, 2.0 litres for women, under normal temperature and a moderate activity level. Neither figure was calculated for desk work specifically, and neither says anything about timing across a day. They answer "how much," in general terms, for a whole 24 hours. Nobody's written the version for a screen-heavy nine-to-five.

What This Doesn't Tell Us

None of this is a claim about dehydration, concentration, or energy. The regulation doesn't measure what drinking water does to a working day, and neither does this piece. What's observable without needing a study to confirm it is just the moment itself: water that's been accessible the whole time, sitting in a day structured in a way that left it untouched.

Why 0800Labs Is Interested

This is the same gap the rest of the Workday Hydration occasion sits in: the space between what's technically on offer and what actually happens at a desk between one meeting and the next. We call that occasion Workday Hydration. It's our own term, not an established category, and not a claim about what drinking water does for anyone. It names the moment, not a mechanism.

We're building something for that moment. If that's useful, the waitlist is below.
