United Kingdom e-invoicing
Europe non-EU · Peppol – core interoperability network (confirmed 23 Jun 2026); decentralised, no real-time reporting at launch
Last updated September 21, 2026
Announced at Autumn Budget 2025: from April 2029 all VAT invoices for B2B and B2G supplies must be issued in a specified electronic format. Peppol was confirmed as the core interoperability network on 23 June 2026; HMRC and DBT will publish the roadmap and phasing at Budget 2026 (28 Oct 2026). NHS England already requires Peppol e-invoicing from suppliers, and public bodies must accept EN 16931 e-invoices under the Procurement Act 2023.

All VAT invoices e-invoiced from April 2029
Does this apply to me?
Two questions. The fixed-establishment rule is where most foreign businesses get it wrong.
Is your business established in United Kingdom (registered office, branch or fixed establishment)?
Do you make intra-EU B2B supplies involving United Kingdom?
United Kingdom: VAT-registered – expect the 2029 mandate to reach you
The April 2029 mandate covers all VAT invoices issued by VAT-registered businesses (B2B and B2G), so a UK VAT registration normally means it reaches you – unless the Budget 2026 roadmap (28 October 2026) carves out non-established businesses. There is no e-reporting at launch. Watch the roadmap before planning.
Not in scope for United Kingdom
With no establishment and no registration or trade in United Kingdom, the mandate doesn't apply to you today. Revisit this if you open a branch, warehouse or start supplying into United Kingdom.
United Kingdom: domestic mandate from April 2029
The UK has a confirmed domestic mandate: from April 2029 all VAT invoices, B2B and B2G, must be issued as e-invoices over Peppol. ViDA does not apply to the UK. Build EN 16931 / Peppol capability now and watch the Budget 2026 roadmap on 28 Oct 2026.
No e-invoicing mandate applies in United Kingdom today
No e-invoicing mandate applies in the UK today (NHS England suppliers excepted, and public bodies must accept EN 16931 invoices). The mandate for all VAT invoices starts April 2029 – roadmap at Budget 2026.
