What is the 2029 UK
e-invoicing mandate?

From 1 April 2029, VAT invoices will need to be exchanged as structured electronic data rather than traditional paper or PDF invoices. For construction businesses, that means more than meeting a new compliance deadline – it means reviewing how invoices move between systems, projects and supply chain partners, and where greater automation could remove friction today.
