About

Research-led,
evidence-based water quality.

The Honest Water Company was founded to give people clear, credible information about their tap water — and an honest answer on what to do about it.

Our approach

We give you the evidence first. We know the industry we work in, we carry out independent testing, we publish transparent results, and we leave you to make an informed decision.

Our mission

Safer drinking water for homes across the UK.

We were formed with a single aim: to make safer, healthier drinking water straightforward for households across the country. Cleaner water that also tastes better — established through evidence, and installed properly.

Independent testing
On-site readings at your own tap, not assumptions from a postcode.
Certified systems
Reverse osmosis certified to NSF/ANSI 58, PFAS as standard.
Transparent results
Before-and-after readings, and research we publish openly.
