How to win business

To enable suppliers' invoices to be processed efficiently we ask that the these guidelines are followed:

  • all invoices must show an invoice number and date
  • all invoices must be addressed to the full legal entity, ie, Wessex Water, as shown on your purchase order
  • your full company name and address must be clearly shown
  • the VAT registration number must be quoted on the invoice if it is being charged
  • the VAT rate and VAT amount must be displayed, ie, 20% if it is being charged.

Pleas note that invoices failing to meet the above guidelines will be returned without processing, potentially causing delays in payment.

Our requirements

Goods and/ or services should only be delivered upon receipt of a valid purchase order.

All invoices must be submitted to us by email and include:

  • a valid purchase order number.
  • a clear description of the specific goods or services provided 
  • the date the goods/ services were provided 
  • a breakdown of costs being charged on the invoice.

Other payment information

All payments are made by BACs transfer or credit card.

Please note that Wessex Water Services Ltd would like to move to weekly card payments if this acceptable with your company’s finance team.

To accept weekly card payments, please complete our supplier onboarding registration form.

Our basic payment terms are end of the month plus 30 days but this can depend on the supplier.
