Panel discussion: the UK e‑Invoicing mandate and its impact on construction

📅 22nd April 2026 | 11:00 - 12:00 BST

Can’t make it live? Register and we’ll send you the recording.

Panel Logo Group-1

The shift to structured digital invoicing goes far beyond finance and AP teams - it will reshape systems, processes, and supply chains across construction. In this session, we’ll recap what’s confirmed, highlight the industry’s immediate priorities, and address common misconceptions, including why PDF extraction isn’t a viable long‑term solution.

Join Joe Sellwood, Head of Source to Pay at Amey Group, and Ellen Leith, CEO of the Purchase to Pay Network, and Tim Cole, e-Invoicing expert at Causeway for an exclusive live discussion.

Our host, Juliette Foster (BBC, Sky), brings her signature clarity to this practical, panel-led discussion on what the UK e-Invoicing mandate means, beyond the headlines.

You’ll also be able to put your questions directly to the panel when you register.

Why attend

Understand the mandate in practice – and why it represents an operational change, not just an AP initiative

Learn how leading contractors are preparing – with real‑world insight from Amey
