Self-lay providers

As an alternative to having new water mains and service connections laid by us, you can choose your own contractor, also known as self-lay providers (SLP). Once the SLP has completed your project, we’ll then adopt the water network, as long as it meets our requirements.

Finding a self-lay provider

To make sure all work is carried out to national industry standards, self-lay providers must be accredited to the Water Industry Registration Scheme (WIRS), run by Lloyd's Register.

You can find a WIRS accredited self-lay provider, along with information about the scheme, on the Lloyd's Register website.
