What is the UK e-invoicing mandate?

Definition

The UK e-invoicing mandate requires VAT invoices between VAT-registered businesses, including public bodies, to be issued as structured e-invoices from 1 April 2029. HM Revenue and Customs and HM Treasury confirmed it at Budget 2025, and the October 2026 roadmap names Peppol as the core network that carries the invoices.

Network: Peppol, decentralised

How UK e-invoicing will work

The UK chose a decentralised model: invoices travel between businesses through certified Peppol Access Points rather than through a central government platform that clears each one. The 2025 consultation, open from February to 7 May 2025, drew 342 responses, and the government's response confirmed the mandate for business-to-business and business-to-government VAT invoices. A PDF or Word invoice does not count as an e-invoice. The roadmap, published on 28 October 2026, sets the steps: primary legislation in Finance Bill 2026, expected to become law in spring 2027; a technical consultation on standards in spring 2027; final standards between October 2027 and April 2028; software provider requirements in spring 2028; readiness testing with software providers in summer 2028; and accreditation of software providers before 1 April 2029. Sales to consumers, cross-border transactions and non-VAT invoices are outside the mandate, and businesses that are not VAT-registered are not required to take part. Limited exemptions, including for digitally excluded people, are due by April 2028. Real-time digital reporting is not part of the 2029 start; a separate consultation on it runs to 20 January 2027. Xero already registers clients on the Peppol network and turns received e-invoices into draft bills.

Common questions

When does e-invoicing become mandatory in the UK?+

From 1 April 2029 for VAT invoices between VAT-registered businesses and public bodies. HM Revenue and Customs and HM Treasury announced the mandate at Budget 2025 and published the implementation roadmap on 28 October 2026.

Will UK e-invoicing use Peppol?+

Yes. The roadmap names Peppol as the UK's core interoperability framework, with invoices exchanged through certified Access Points and UK-specific Peppol requirements for software providers.

Who is exempt from UK e-invoicing?+

Sales to consumers, cross-border transactions and non-VAT invoices are outside the mandate, and businesses that are not VAT-registered do not have to adopt it. Further limited exemptions, including for digitally excluded people, are due by April 2028.

Does HMRC e-invoicing include real-time reporting?+

No. The 2029 mandate covers the exchange of e-invoices only. HM Revenue and Customs is consulting separately, until 20 January 2027, on whether to add digital reporting later.
