Whether you're on municipal water in the city or drawing from a private well just outside it, we bring the same free water test and honest, pressure-free recommendations to every home we visit in London.

London is a bit of a split city when it comes to water supply. Homes within city limits are typically on treated, chlorinated municipal water, while a meaningful number of properties in and around London rely on private wells instead β and each comes with its own set of considerations.
For homes on the municipal supply, hardness and chlorine taste are the most common complaints we hear. For homes on a private well, the picture is usually more complex β hardness alongside iron, sulfur odour, or sediment, all in varying combinations. Rather than assume which applies to your property, we start every London visit with an on-site test of your actual water.
Whatever's coming out of your tap in London, we've likely already tested and treated something similar nearby.
We're not a national call centre. When you book a test in London, a technician who actually knows the area shows up at your door.
From softening a city home to setting up full iron, sulfur, and sediment filtration for a well, our technicians handle both regularly.
Most systems we install in London are up and running the same day our technician arrives β no waiting weeks for a follow-up visit.
Your free water test results come with a straightforward recommendation β including telling you when you don't need to buy anything at all.
If you're on a private well, take a look at our dedicated well water solutions. Otherwise, browse our full product lineup, or see every area we serve on our service areas page.
Whether you're on city water or a private well, find out exactly what's in your London home's water β for free.
