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 codesforadoptionwater@yorkshirewater.co.uk.

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.

    At this point, we will ask you if you require any work to be carried out by Yorkshire Water to be done at this stage.

    Alternatively, if you want to request the work to be done at another time, please fill in our Call off Request form.

    Please keep us up to date with your activity in the Yorkshire Water area by completing the weekly whereabouts form on the Thursday prior to the following week.

    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 water quality requirements document.

    Once the main is laid and you have a chlorination pass certificate, you need to send us the chlorination notification for approval to connect the new main to the spur main we have laid as part of the non-contestable works (if applicable), 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 the Codes for Adoption required standards, please refer to theDesign and Construction Specification (DCS)document


    You will also need to meet our Yorkshire Water site inspector on site to agree any remedial action (if applicable) in view of receiving a mains vesting certificate.

    Please bear in mind, we will contact you to organise a final walk of the site to make sure everything is ok. This will be around 12 months after the vesting certificate has been issued.

    If you come across any issues with the new water mains, you must contact us immediately for discussion.

    Service Connections

    Please make sure you inform us of any service connections you are making to our network by completing our weekly whereabouts form and send it to SLP_Mailin@yorkshirewater.co.uk. You must have approval from ourselves to connect any service connections to our network. If you do not have this, you will need to fill in our self-lay connection to existing off site mains request form and email it to SLP_Mailin@yorkshirewater.co.uk so the work can be risk assessed by our Network Engineers.

    We may also want to ensure the property complies with the water regulations and this will be done on routine site visits.

    We try to give our customers as much choice as possible when it comes to the location of water meters whilst retaining ongoing operational control of our network. Our meter location policy will assist you with the options available. In some cases, meters into blocks of flats will need to be installed internally.

    Information can also be found in the Design and Construction Specification (DCS) document. Some property types will also require sprinkler systems fitting to comply with building regulations. Our policy and guidance document on installing a domestic fire sprinkler system will assist you with the design of these systems.

    When plot connections have been made by an SLP, we need to know about this so we can set up our billing file ready for a new customer to move in, invoice for the infrastructure charges (if applicable) and report the time it has taken for you to inform us of these details to Water UK on your behalf. Please fill in our meter installation form and send it to SLP_Mailin@yorkshirewater.co.uk.
