UK e-invoicing from April 2029: Peppol confirmed, roadmap due at the Budget

Country reference

• Country: United Kingdom (Wave 1 expansion country)
• Authorities: HM Revenue and Customs (HMRC); Department for Business and Trade
• Topic: Mandatory electronic invoicing for VAT invoices
• Key date: Roadmap due at the Budget on 28 October 2026; mandate from April 2029
• Law: Value Added Tax Act 1994, with implementing legislation to follow

What has been decided

• At Budget 2025 the government announced that e-invoicing will be mandatory for all VAT invoices from 2029. HMRC’s 2026 roadmap update gives the date as April 2029.
• The consultation response of 26 November 2025 drew on 342 responses.
• Scope: VAT invoices, which are typically issued for business-to-business and business-to-government transactions. Sales to consumers are not covered.
• Model: decentralised. Businesses exchange invoices through service providers, not through a central government platform.
• Real-time reporting: not introduced with the 2029 mandate. The government will consider it once e-invoicing is well established.

What happened in 2026

• January: HMRC began detailed design work with industry.
• 23 June: the tax update confirmed Peppol as the core interoperability network.
• 2 July: HMRC’s roadmap update said it is working with the Department for Business and Trade to publish an e-invoicing roadmap at Budget 2026, with milestones to April 2029.
• 23 June, also: HMRC said it is exploring the use of supplementary VAT data that businesses already hold in digital accounting systems.

What is not yet known

• Whether the mandate starts for all businesses on one date or in phases.
• The invoice data standard and the rules for service providers.
• Penalties, and how the rules apply to overseas businesses registered for UK VAT.

What to do now

• Read the roadmap on 28 October and note the first milestone that applies to you.
• Ask your accounting or ERP vendor whether the product can send and receive Peppol invoices.
• Clean customer and supplier master data, especially VAT numbers and addresses.
• If the group already runs e-invoicing elsewhere, reuse that data model.

Our take

The United Kingdom is late to e-invoicing but has chosen the same Peppol base as Singapore, and the same direction as the United Arab Emirates and Saudi Arabia. A group present in several of these markets gains most by building one invoice data standard now and adapting it per country.
