Water pipe responsibility

Who maintains the pipework and who to contact if you have any problems.

Understanding pipe responsibility

There a two main groups who are responsible for water pipes:

  • The water company
  • The consumer

The water company is the organisation who provide your home with drinking water.

The consumer is the person living in a home, using water there.

Check how your water supply is set up when you move into a new home

If you're moving in to a new home, and the property is over 20 years old, we recommend that you find out about the condition of the pipework. 

If supply pipes are neglected it can affect the water supply and damaged pipes can go unnoticed, storing up problems for the future.

Your supply pipe could be 100 years old or more. This can become problematic when you fit modern appliances like washing machines and power showers in older homes as the Victorian pipework is not designed to cope with such high water use.

If you experience poor supply or pressure, it could be due to older pipework, so it's worh finding out how your home is connected and making changes to your pipes if necessary.

 

The kind of supply your home is likely to have

Generally, different types of homes have different types of supply.

 

Housing estates, particularly council estates, were usually built with one large pipe running along the back of the homes that feeds into each house, meaning there is shared responsibility for the large pipe.

Of course there could have been many things done to your property since your home was built that means your home doesn't fit into these categories, so it's always best to find out

Pipe responsibility on a shared supply

A shared supply - also often called a joint supply - is where a group of homes connect to our network at the same point. This means all properties share responsibility for repair and maintenance of the pipework.

Find out if you're on a shared supply

You can find out if you're on a shared supply by checking how many external stop taps are outside your home.

External stop taps or boundary boxes are usually found in the pavement at the property.

If there is an external stop tap outside every home on the street, then each home will have its own supply. If there's only one, you are likely to be on a shared supply with your neighbours.
