Connections Off An Existing Mains

Connections off existingFrom January 2022 we will be increasing the contestable activity that we will allow accredited SLPs.

SLPs with 'Mains and Services Accreditation' can apply for 25/32mm connections as either a temporary, part of a site or stand alone connection.

SLPs with 'CRUPMC, Construction Routine Under Pressure Mains Connections Accreditation' can apply under pressure branch connections up to 63mm off designated mains for either non standard services or mains.

This will include under pressure connections to our existing network up to and including 63mm in size (subject to a number of criteria being met related to the host main).

Both 25/32mm and 63mm criteria includes:

  • Up to a 12” host main
  • Where the host main material is either DI/CI/SI/AC/PE/Barrier Pipe/Steel
  • Where a shut off is not required
  • Where the main is not considered to be strategic

Please use the application forms below if you wish to apply for a connection on behalf of a developer.

When you are ready to make your connections, you will be required to complete our Request for Permission to Work form and this is to be sent to us no less than 5 days before you intend to make the connections. We will review the information on your form and provide you with approval. You can then make your connections on an agreed date and fit the water meter (where applicable).

Within 1 day of the connection being made, the SLP must notify United Utilities that the work has been completed. Within 5 days, a Completed Connection form must be sent to us. You must use your tracker to inform us of the connected plots, the date of the connection and the meter serial number.

Guidance on metering including reporting serial numbers, tagging and our meter location policy can be found in our Meter Guide for SLP’s (PDF 496 KB opens in a new window).

Alternatively, if we are fitting the meter, we will contact you to arrange a time to do this. We will then register the connection and meter on our billing system.
