Do you know what's in your tap water?

Your water leaves the water treatment plant clean. What happens between there and your glass is a different story — and most people have no idea.

The journey from
plant to tap

Your water leaves the water treatment plant meeting all required standards. But once it enters the distribution network, it travels through ageing underground pipework systems — more commonly made of plastic — and into your home. Along the way it picks up microplastics, chemical leachates, and contaminants never present when it left the plant.

This is called point-of-use contamination. It's poorly understood, rarely discussed by water companies, and not adequately addressed by current regulation.

What are PFAS — "forever chemicals"?
PFAS are thousands of synthetic chemicals used in non-stick cookware, food packaging, firefighting foam, and industrial processes. They do not break down in the environment or in the human body. They accumulate in water courses, soil, and living tissue over time.

35–37%
of English and Welsh water courses contain medium-to-high risk PFAS levels — yet current UK regulation does not require water companies to test for, or remove, most of them.

The problem with
jug filters

Standard jug filters are designed to reduce limescale and improve taste. They are not certified to remove PFAS, heavy metals, or microplastics. They also store your filtered water in plastic, and degrade rapidly without regular maintenance.

Ceramic and carbon block filter media — not plastic — means nothing is introduced to your water during filtration.

Research-led.
Evidence-based.

We test local tap water for PFAS, heavy metals, and microplastics — and we publish what we find. Our approach is grounded in independent research, certified testing methodology, and transparent reporting. We believe you should understand the evidence clearly before you consider any solution.

We install best-in-class filtration systems from certified manufacturers. We test your water before and after installation. We show you the results.

We don't overclaim. We don't sensationalise. We follow the data.

The case for
filtered water

A correctly installed, certified filtration system doesn't just improve the taste of your water. It removes the contaminants that water treatment alone can't address.

Cleaner water also has measurable benefits beyond what you drink. Reduced limescale and dissolved minerals extend the working life of kettles, dishwashers, and boilers. Softer, purer water is gentler on skin and hair — particularly for those with sensitivities or conditions like eczema. And with a subscription filter replacement plan, the system maintains its performance without you having to think about it.

The evidence is measurable. Before and after water testing consistently shows dramatic reductions in dissolved solids, PFAS compounds, microplastics, and heavy metals. These aren't marginal improvements — they're the difference between drinking what your water company says is in your water, and drinking what actually comes out of your tap.
