Updated 31 July 2026
Exclusive Sponsor
The United Kingdom will mandate e-invoicing for all VAT invoices from April 2029, covering B2B and B2G transactions. HMRC confirmed in June 2026 that Peppol will be the core interoperability network, and HMRC and the Department for Business and Trade will publish the implementation roadmap at Budget 2026 on 28 October 2026. The model is decentralised, with no clearance step and no real-time reporting introduced alongside the mandate. Public bodies already have to accept compliant e-invoices, and suppliers to NHS England must issue over Peppol.
