Adoption codes
Find out the latest on Codes for Adoption Agreements here.

One of the key themes of the Code of Practice for Adoption Agreements published by Ofwat is to ensure that developer services customers can easily understand and access the choices available to them in the new connections market.


The Code also requires us to publish our current procedures for making, varying or terminating adoption agreements on company websites.


Full details of the Code for Adoption Agreements can be found here.

Delivery options

There are three delivery options available to customers for the new connections infrastructure they need.


For new water mains and services, the options are:


Choose to appoint an accredited Self-Lay Provider to provide the mains for future adoption by us


Since 2017, we've worked with Water UK and a number of Self Lay Providers to develop and implement the Code of Practice for Self Laying of Water Mains and Services – England and Wales.


As part of that work, we're required to publish a Local Requirements document. This document highlights any company-specific information, which gives clarity to Self Lay designers and construction companies. Together, this makes sure there is no uncertainty over our requirements.


Our Local Requirements document is available to download below. It replaces any former company-specific addenda to the previous Codes of Practice.


We can provide requisition mains and services


All of our processes, application forms and guidance notes can be found here.

Details of this can be found on OFWAT's website.

Levels of service

Since July 2015, water and sewerage companies have reported against a nationally agreed set of developer services metrics.


These metrics have been extended to include Self Lay. The results are published quarterly by Water UK and the latest reports can be accessed here.


From 2 April 2018, the Code of Practice for Adoption Agreements also require us to provide customers with appropriate redress for failure to meet the current minimum levels of service.


The Adoption Codes Redress Scheme information can also be found below.
