UK E-Invoicing Roadmap: One 2029 Start Date, Requirements by April 2028

Latest Update (28 October 2026): UK Publishes Its E-Invoicing Roadmap

On 28 October 2026, HMRC and the Department for Business and Trade published the Roadmap for e-invoicing implementation.

The headline: a single start date for everyone. From 1 April 2029, UK VAT-registered businesses and public bodies will need to be able to issue and receive VAT invoices as e-invoices, unless a specific exemption applies. Peppol will be the UK’s core interoperability framework.

The detailed rules are not out yet. A public technical consultation on the standards will launch in Spring 2027, and the full requirements will be published between October 2027 and April 2028, giving at least 12 months to prepare.

Key Dates

• Spring 2027: public technical consultation on the UK e-invoicing standards and Access Point certification requirements; first guidance on EDI and legacy systems; primary legislation, to be introduced in Finance Bill 2026, expected to become law subject to Parliamentary approval; confirmation of the UK Peppol Authority arrangements
• Autumn 2027: further guidance on EDI and legacy systems
• End of 2027: guidance for specific groups within the VAT-registered population
• October 2027 to April 2028: key requirements published, covering scope, exclusions, standards, guidance, business identifiers and requirements for software providers
• April 2028: updated VAT guidance, details of taxpayer obligations and of the exemption process for digitally excluded persons
• Spring to Winter 2028: readiness testing with software providers
• Winter 2028: infrastructure and governance arrangements operational
• 1 April 2029: mandatory e-invoicing begins; software providers are expected to have completed any required accreditation with the UK Peppol Authority

What Else Does the Roadmap Say?

• Exemptions: tightly defined and limited, mainly for digitally excluded persons, with an approach intended to follow Making Tax Digital for VAT
• Non-established taxable persons: subject to the same invoicing requirements as UK-based entities
• Not required: sales to consumers and cross-border transactions, although e-invoices may be issued voluntarily
• EDI: businesses can continue using it, but must also be capable of exchanging e-invoices through the new framework
• Penalties: the existing VAT invoicing penalties framework will be used as a basis, as far as possible
• UK Peppol Authority: HMRC will take over the role from NHS Supply Chain. Finance Bill 2026-27 gives HMRC the functions it needs to prepare, but the timing of the transition has not been determined yet

Businesses can start planning now: review your current invoicing processes, check that your ERP or software provider will support the future UK requirements, and talk to our e-invoicing team about getting ready. For the full picture, read our complete guide to e-invoicing in the UK.

HMRC has published its 2026 Progress Update to the Transformation Roadmap, confirming that the government will mandate e-invoicing for all VAT invoices from April 2029, and giving the clearest picture yet of how the programme is being developed.

Where the E-Invoicing Programme Stands

The update confirms the following on e-invoicing specifically:

• HMRC is working with the Department for Business and Trade (DBT) to publish an e-invoicing roadmap at Budget 2026 that will set out the milestones to implementation in April 2029.
• That roadmap will build on co-creation work taking place with industry representatives in 2026.
• HMRC has already launched Policy Development and Technical Workshops with DBT and industry stakeholders to work collaboratively on the design of the UK e-invoicing regime, feeding directly into the roadmap.

This confirms the sequencing businesses have been expecting: detailed standards and technical requirements are due at Budget 2026, roughly two and a half years ahead of the 2029 mandate. The update frames e-invoicing as one part of HMRC's wider digital-first transformation of UK tax administration, rather than a standalone initiative.
