Invoice Payment Practices

This information is as reported by the business, and responses are in their own words.

Payment Terms

Standard payment terms

Standard payment terms Sellafield currently employs three different payment terms that can be considered as standard, as described below: Net Cash Monthly - Payment is made by the end of the month following the month in which the invoice is dated - this payment term remains in use for contracts / frameworks in place prior to 26/02/2015 – the date upon which the Public Contracts Regulations 2015 came into force. Use of this payment term is diminishing as these legacy contracts / frameworks come to an end. 30 Days from Invoice Validation - Payment is made no later than a period of 30 days from the date on which Sellafield Ltd has determined that the invoice is valid and undisputed. This payment term generally applies to contracts / frameworks placed from 26/02/2015 onwards. 21 Days Net - Payment is made within 21 days of the date of the invoice – this is tailored to take account of the payment process under NEC 3 contract terms and conditions

Were there any changes to the standard payment terms in the reporting period?

Dispute Resolution Process

Sellafield Limited actively seeks to resolve disputes by discussing them with the relevant supplier(s), typically involving contract management teams from both parties. Where agreement cannot be reached at a working level, the dispute will be discussed between senior representatives of the parties. Where it is not possible to reach agreement most contracts will contain a dispute resolution procedure, which details the route for mediation, arbitration and bringing a claim in the courts.
