Dispute resolution
WSP has a commitment to managing all disputed invoices in a timely manner. Our key steps in this process are: Disputed invoices are identified and raised by the person responsible for sourcing the supply or service, whom will then liaise with the business stakeholder. The dispute will then be owned and analysed internally by the business stakeholder and raised directly with the supplier. If settlement of the dispute cannot be reached between the business stakeholder and the supplier, escalation to Procurement and or other appropriate departments will be engaged in the process. Where a resolution cannot be reached, there are a number of potential dispute resolution methods such as mediation, adjudication, expert determination, litigation and / or arbitration.

How UK payment reporting works
What is a Payment Practices Report?
What does "paid outside agreed terms" mean?
How often is this data updated?
Is this official government data?
How this is compiled. Built from official records only: Companies House and the gov.uk payment-practices service. The payment figures are self-reported — companies over the size threshold must file them by law and the board signs them off. No credit-agency data. The numbers are theirs; the plain-English read is ours. This is information compiled from public records under the Open Government Licence v3.0 — not a credit rating and not advice.
The 31-day comparison figure is the median across 6,104 companies with a current statutory report — every sector pooled, not an average of sector medians (how the figure is built).
