Water meter installation and relocation in London
Here is the thing most people selling meter installation will not lead with: your water company will fit the meter itself free of charge, provided your supply allows it. What they will not do is alter your internal pipework, split a shared supply between flats, or move a meter to suit a kitchen refit. That is the work Ninja Plumbers actually handles, and where the free option would cover you, we will point you straight there instead of quoting for it.

Worth knowing first
A bit of this might save you from needing a callout at all — we'd rather you knew it upfront.
Your water company fits the meter free
Thames Water and the other suppliers will install a meter at no charge where the supply allows it. Ask them first. We are the people to call when they have been out and said they cannot, or when you need something moved.
Shared supplies are the usual blocker
A Victorian house carved up into flats very often has just one supply pipe feeding every home in the building. Nobody can get an individual meter until that shared pipe is separated into one run per flat, and that separation work is the real job here — worth understanding upfront before you decide whether metering is even worth pursuing.
It is the right moment to replace the stopcock
If the pipework is open anyway, a stopcock that is stiff, weeping or seized should be changed then. Doing it later means draining everything down a second time.
Check for a leak before you go metered
If there is an existing underground leak on your supply, going metered means paying for it. Watch the meter with everything off before you commit — or ask us to trace it first.
Common questions
Can you fit the meter itself?
The meter belongs to the water company and they install it. We do the pipework that lets them, and we move meters that are already installed inside the property.
Should I switch to a meter?
Broadly, if there are fewer people in the house than bedrooms, metering usually costs less. Most suppliers publish a calculator, and they also let you switch back within a set period.
My flat shares a supply with the rest of the building. What now?
The shared pipe has to be split into separate runs before individual metering becomes possible. It is a genuine piece of work, and it usually needs sign-off from the freeholder too, so get it priced before making promises to the other flats in the building.
Can you move the meter for a kitchen refit?
Yes, where the new position is reasonable and accessible for reading. Tell us where the units are going and we will tell you what is possible.
