What is Codes for Adoption?
Ofwat have introduced a code which sets out a framework of overarching principles within which we must deliver clean water adoption agreements and places obligations on us to work with our customers to develop, agree and maintain sector guidance (setting out the processes by which parties can enter into adoption agreements) and model adoption agreements.
If you would like to see the detail of regulatory requirements set by Ofwat, this can be found here: https://www.ofwat.gov.uk/regulated-companies/markets/connections-market/code-adoption-agreements/
Ofwat has approved the Water Sector Guidance documentation that was created to meet the requirements of their Code for Adoption Agreements. This documentation can be found here: https://www.water.org.uk/revised-water-code-documentation-24-june-2020/
This was introduced as the new industry approach to water adoption for England on 01 January 2021.
We have reviewed our guidance documents and aligned these new rules to our current processes.
Please find the Annual Contestability Summary (ACS) and Design and Construction Specification (DCS) documents here for you to view.
To allow you to see the differences between the basic OFWAT standard DCS document and Yorkshire Water’s specific requirements, we have shown Yorkshire Water’s details in blue.
How can you get involved?
We host a monthly forum on the first Friday of every month for our self-lay customers to discuss the new codes for Water and our general processes and seek feedback on how we can improve the services we offer. If you would like to be involved in this going forward, please send an email to firstname.lastname@example.org.
How can you keep up to date with progress?
We will continue to share updates on progress on this page so please keep it in your bookmarks for a quick reference in future.
The Supporting Documentation and Guidance section contains the Policies and procedures relevant to Codes for Adoption.
Do you know you can now apply and pay your application fees online? We are working hard to continually develop and improve your customer experience, for more information and applications please click here.
If you have decided to use a Self-Lay Provider (SLP) to lay your water mains and services and they are designing the onsite mains, they will require a point of connection (POC) into our network before making an application to Self-Lay mains.
If you require access to our plans this can be done by filling out a web mapping request form, and emailing the application to
When you are carrying out work, you must inform us by completing the weekly whereabouts form on the Thursday prior to the following week and emailing it to us at SLP_Mailin@yorkshirewater.co.uk.
Where you have any issues or would like to discuss anything with our Network Controller or site inspectors direct, their contact details can be found here.
Once the mains are laid, they will require chlorinating, to ensure this meets our required standards please read both Water UK principles of water supply hygiene and our chlorination guidance document.
Once the main is laid and you have a chlorination pass certificate from our water quality scientist, you need to make an application to connect the new main to the spur main we have laid as part of the non-contestable works, or if you are connecting between phases please fill in our routine in line connections form.
The main is now ready for vesting. Prior to this you must have produced an as-laid drawing of the new main, to ensure this meets our required standards, please read our Main Laying as built drawing guide.
You will also need to meet our Yorkshire Water site inspector on site to agree any remedial action or receive a mains vesting request form.
