Water connection processes and timescales

Last reviewed:

When you apply for a water connection, we’ll complete the work as efficiently as possible to prevent any delays to your development.

Please note, if you're connecting a non-household property, you'll need to appoint a retailer for the site. For more information, please see our News and Improvements section.


Supply pipe connection

Once you’ve paid your quote and your pipework has passed our Water Regulations inspection (which we’ll do within seven days of your call) we’ll start planning a connection date.

This typically takes up to three months because we often need to get permission before carrying out work in a road or footpath, or on privately-owned land.

The connection work itself is likely to take up to four days to complete. You can read more and apply for a new water supply connection below.

Once you’ve paid your quote, we’ll contact you to arrange a meeting. At this meeting we’ll confirm the scope of works, lead times, on-site facilities and any traffic management requirements. We'll need to talk to the local authority and other bodies responsible for roads and traffic, which can include TfL and bus companies.

We’ll plan to construct the main in line with your phasing requirements within 90 days of you accepting your quote. You can read more and apply for a new water main below.

For many of the connections we carry out, the traffic management plans affecting the area require highway approval by the local authority. In complex cases, the approval process can take up to 12 weeks. If this is the case, we’ll contact you to agree a later connection date. You can read more about traffic management below.
