United Kingdom E-Invoicing

Key compliance facts

About United Kingdom E-Invoicing

The UK government has confirmed mandatory e-invoicing for all VAT invoices (B2B and B2G) from April 2029, ending years of deliberation. The Autumn Budget 2025 (consultation outcome updated 26 November 2025) confirmed: a decentralised 4-corner model (no central government platform), Peppol-leaning interoperability, and explicit separation between mandatory e-invoicing and real-time reporting (RTR) — with RTR/CTC explicitly excluded from the 2029 launch but potentially considered later. A 12-week HMRC/DBT consultation ran February-May 2025. The detailed implementation roadmap and technical standards will be published at Budget 2026 (November 2026). Stakeholder collaboration started January 2026. Public bodies must already accept BS EN 16931-compliant e-invoices; B2G via Peppol is mandatory for NHS suppliers. The mandate covers structured machine-readable invoice data — PDFs, Word files and OCR images expressly do NOT qualify. Northern Ireland may face additional ViDA e-invoicing/e-reporting obligations from July 2030 for cross-border supplies of goods to the EU. The government cites projected 20% reduction in late payments and ~£11,300 annual savings for small firms.
