Water connection

If you require a new connection or replacement of an existing supply, you will need to apply for a water connection application.

Before you apply

There are a few things that you need to know to ensure that water connection application is the right option for you.

What is a water connection, and when do I need one?

A water connection is how we connect your property or site to our water mains.

Reasons when you may need a new water connection:

  1. Building a new house or building
  2. When you are renovating, changing the use of property, or building an extension
  3. When you are building new commercial premises
  4. When you are converting a building into many flats
  5. If you are building a property in a new location and need to connect to our network
  6. When you are installing an agricultural trough
  7. When you need a temporary water supply
  8. Upgrading/replacing your existing supply to increase the flow due to increased demand.
  9. If you are looking to split into or from a shared supply within commercial unit
  10. If you need fire supplies
  11. Relocating meters or supply pipes

Step 2 – We’ll provide your Quote

In order to produce a quote for the construction costs at your project, we may need to carry out a site survey to identify where your water connection will be made. Our water design contractor Clancy Docwra may visit your site to carry out the survey.

It is important that any specific access arrangements to your site are made known to us during your application to avoid any delays.

Within 28 days we’ll send your quote, this will include:

  • Quote document, including full cost breakdown including traffic management (if applicable), excavation and reinstatement
  • A photo showing the point of connection (if applicable)
  • References to relevant technical guidance for pipework installation (if applicable)

Our quotes are valid up to the end of the financial year (31st March), for quotes made in Feb/Mar we give a 2-month extension. If the quote expires or there is any change to the way you want to lay your pipes or connect into our network, then you’ll need to ask for a requote for your site.

Step 3 –  You accept and Pay for the works

You review the quote, accept, and pay for the construction works to proceed with the project.

Step 4 – We grant water regulation consent

Step 5 -  You lay your private supply pipe

After you’ve accepted the quote, paid for the water connection, and filled in your water regulations questionnaire (if applicable), you will need to arrange a qualified plumber/contractor to lay the private supply pipe from your property. You can find approved plumbers in your area by entering your postcode on the Watersafe website. 

Alternatively, you can do it yourselves following instructions and requirements from our guidance below. Please download this guide and share it with your plumber/developer, who will be carrying out pipework for your project.

Step 6 – You Book your site inspection

When your private supply pipe is laid, you will need to request your site inspection before we complete a water connection to the main supply. Please allow 2 days for us to process your booking. If your property or site is new, you must provide your postal information using GetConnected portal, before we can progress with the water connection works.

Step 7 – We complete your water connection and install the meter

Once your private supply pipe has passed the site inspection your new connection will usually be completed within 21 days. If a road closure, or private land entry is required then the connection may take up to 3 months, which will be stated in your quotation if it applicable to your project.

Following the connection, your new supply will be left live with a meter installed. From this point on you will be responsible for the bill.
