What's really in your tap water

Being compliant doesn't mean your water is free from harmful contaminants.

Your supplier reports its water as compliant, and on its own terms that is true. But compliance is a measurement regime with defined edges, and it is worth understanding what those edges are before you read it as a clean bill of health.

How water quality is actually measured
By zone, not by property. Results are published for a water supply zone that can cover tens of thousands of homes, as a rolling 12-month typical value. It is an average across an area, not a reading from your tap.
Against a fixed list. Compliance is judged against a defined set of regulated parameters. Anything not on that list is not reported — which is why PFAS does not appear at postcode level and microplastics are not routinely tested at all.
Against a limit, not zero. "Within limits" means a substance measured below a threshold judged acceptable. It does not mean the substance is absent.
Your own plumbing is the variable. No zone figure can account for your service pipe and internal pipework, which is where lead and copper enter — and that is specific to your property.

None of that makes mains water unsafe. It means "compliant" answers a narrower question than most people assume. Below is what is known to reach UK taps, and what the evidence actually says about each one.

PFAS
Found in 35–37% of UK drinking water samples. PFOA is classified by the WHO's cancer agency as carcinogenic to humans. Not removed at the treatment works.
Microplastics
Routinely detected in UK tap water, and now found in human blood and tissue. The health effects are not yet established — which is not the same as established safe.
Lead
There is no safe level in drinking water. Mains figures look clean; the unknown is your own supply pipe and fittings.
Chlorine & THMs
Added to keep the supply safe. Its by-products are regulated in their own right, and it is what you taste and smell.
Nitrates & pesticides
Run-off from farmland. Regulated at 50 mg/l, and routinely present below that limit.
Sources: Royal Society of Chemistry (PFAS prevalence in UK samples) · IARC, the World Health Organization's cancer agency (PFOA classified Group 1, carcinogenic to humans; PFOS Group 2B) · WHO (no safe level of lead in drinking water) · Drinking Water Inspectorate. On microplastics, WHO's assessment is that current evidence does not establish a health risk, and that the toxicological data needed to settle it does not yet exist. We would rather set that out than imply otherwise.
How it works

From report to installation.

The same four steps set out in your report. In-home testing at your own tap is carried out on installation day, as part of the work — not as a separate call-out.

01

Free report

Enter your details and receive your Water Quality Report within minutes.

02

System specification

We talk it through, specify the right system and give you a fixed price on the call. The estimate is free.

03

Test & install

One visit — we test at your own tap, fit the system, and take a before-and-after reading on the day.

04

Ongoing maintenance

Filtr replaces your filters on schedule, for as long as you're with us. Optional.

Services

And this is what we do about it.

Every level we install is specified to address PFAS and microplastics as a baseline, not as an upgrade. We specify the right one for your water and your property — never the most expensive by default.

Microplastics, sediment and cysts, plus a dedicated PFAS cartridge. Our entry level, with PFAS covered.
Under-sink
Purity
Reverse osmosis · NSF/ANSI 58
The broadest removal of any home method — PFAS, lead, arsenic, fluoride, chlorine and dissolved solids, certified together, at your kitchen tap.
Reverse osmosis
