All non-household premises connected to the mains water and/or sewerage network should have a Supply Point ID (SPID).

A SPID is used to identify your supply and allows a retailer to bill you for water and wastewater services. Most premises will have:

• One SPID for water, and
• One SPID for sewerage

Your Wholesaler is responsible for creating and maintaining these SPIDs.

 

Why might my premises not have a SPID?

In some cases, a premises may not be registered correctly.

This can happen:

• After a new connection or development, where there is a delay in registration
• Where an existing supply has not been registered correctly by mistake

Premises in this situation are often referred to as “Gap Sites”.

A Gap Site is a property that is receiving water and/or sewerage services but is not currently being billed because no SPID has been created.

 

How do I get my premises registered?

If you believe your premises is a Gap Site, please contact us as soon as possible.

To request registration, submit a request using our General Enquiry Form and include:

• The full address and postcode of the premises
• The business name
• A contact phone number and email address
• The meter serial number (if available)

 

What happens next?

Once we receive your request, we will:

• Check whether a SPID already exists for your premises
• Contact your Wholesaler to request a new SPID if one cannot be found

The Wholesaler may need to:

• Install a new meter, or
• Record the details of an existing meter

They may also contact you to arrange a site visit if required.

The amount of work involved can vary, and timescales are outside of Castle Water’s control.

When will I start receiving bills?

Once your Wholesaler has registered your supply, they will provide us with the necessary details, including:

• Meter serial number
• Pipe size
• Return to sewer percentage
• Opening meter reading

We will then:

• Set up your account
• Calculate your first bill

You will receive a welcome email with your new account details when this has been completed.

 

Domestic premises

If the supply relates only to a home and not a business or non-household premises, you should contact your Wholesaler directly.

Castle Water is a non-household retailer, so we are not able to manage domestic supplies.
