I am interested in working with Anglian Water

Please visit our How to Work with Us and Risk Assessment and Requirement Pages for more information on how to become a supplier for Anglian Water.

I have an Invoice payment query

Please do not hesitate to contact our accounts payable department accountspayable@anglianwater.co.uk or call on 01733 414692. Please note that all invoices should be sent to invoices@anglianwater.co.uk

I have an old purchase order (PO) number, will my order still get processed?

Unfortunately, if your purchase order number is dated over 18 months old it will no longer be valid so will not exist in the system, and you will need to get a new one to be paid. Please speak to the person who raised your purchase order.

If I don’t quote the purchase order number on the invoice, will I still get paid?

No as per our usual terms and conditions, you must quote the purchase order on your invoice in order to be paid.

How will I know if my invoice has been rejected?

You will now receive an email stating why your invoice has been rejected and what you need to do to fix it.

Why might my invoice be rejected?

Below is a list of common reasons your invoice might be rejected:

Quantity issue
Missing or incorrect PO number
PO raised to incorrect legal entity
PO quoted by supplier is finally closed
Invoice quoting incorrect or missing PO

I have a query relating to an invoice, who should I contact?

How will I know if I receive a new purchase order or an amendment to an existing purchase order?

This will be clearly marked when receiving the purchase order. It is important that you check this to ensure there are no duplicated orders.

Standard purchase order can be seen here.

Change purchase order (an amendment to a purchase order) can be seen here.

I haven’t received a purchase order, what do I need to do?

You will always receive a purchase order for goods, services and works, if this hasn’t been received, please make sure you follow up with the person who has asked you to supply the goods, services and/or works to understand what is happening.

I am a supplier on the Ariba Network, what does the upgrade to SAP S/4HANA mean for me?

If you are a supplier on the Ariba Network, then the upgrade to S/4HANA won’t mean any changes. You will still receive an email with your PO as normal, or this can also be accessed via the Ariba Network portal, and you will still submit your invoices via the portal as normal.

Has anything changed with Applications for Payments?

No, everything remains the same.

What is the Ariba Network and how might it benefit me as a supplier?

The Ariba Network is a platform that facilitates business to business transactions globally. This provides a provides comprehensive supply chain collaboration and visibility, enabling seamless connection between Anglian Water and it’s suppliers.

Where do I go to if I have an innovative idea?
