When did the UK's eInvoicing consultation run, and what did it cover?

The consultation ran for 12 weeks, from 13 February to 7 May 2025, led by HMRC and the Department for Business and Trade. It covered the choice of eInvoicing model, how long businesses would need to adopt new standards, how to raise awareness among businesses, and how eInvoicing could streamline VAT reporting, including the possibility of pre-filled VAT returns.

When will UK eInvoicing become mandatory, and what model will it use?

A framework roadmap is expected at Budget 2026 on 28 October 2026, ahead of a mandate that is planned to begin in April 2029. The UK model is a Peppol four-corner model, aligning with the approach already adopted by countries such as Belgium and increasingly across Europe.

Why is the UK introducing eInvoicing now?

The UK is following other European countries, including Italy, France and Poland, which have already used eInvoicing to reduce tax fraud through real-time transaction monitoring, automate invoice processing and simplify VAT compliance. HMRC's consultation reflects a wider shift toward modernising financial processes to make tax reporting more transparent and efficient.

How can a business get involved in shaping the UK's eInvoicing framework?

Businesses can respond to public consultations run by HMRC and the Department for Business and Trade, sharing how a new eInvoicing framework would affect their own invoicing and VAT processes. Taking part early helps ensure the final regulations reflect real operational conditions and gives a business time to prepare ahead of the planned April 2029 mandate.

Here’s what you need to know about the consultation, what it aims to achieve, and how this aligns with broader trends across Europe.

HMRC's eInvoicing consultation: A pivotal move for UK businesses

The UK’s HMRC and the Department for Business & Trade have launched a 12-week public consultation, running from February 13 to May 7, 2025, to gather industry insights on introducing standardised eInvoicing for both Business-to-Government (B2G) and Business-to-Business (B2B) transactions.

This consultation seeks to address several key areas:

Model selection:
Exploring centralised vs. decentralised eInvoicing models (e.g., 4-corner vs. 5-corner models).
Implementation timelines:
Determining the necessary lead time for businesses to adopt the new standards.
Awareness and adoption:
Understanding the current state of eInvoicing awareness and exploring strategies to increase uptake.
VAT compliance:
Assessing how eInvoicing could streamline VAT reporting, potentially enabling pre-filled VAT returns.

Transalis, with its extensive experience in digital supply chain solutions, is contributing valuable insights to help HMRC design a system that balances compliance efficiency with business-friendly implementation.

Transalis' consultative role: Driving awareness and engagement

Our founder, Aniello Sabatino, was introduced to HMRC’s consultation team, given his expertise with CCS (Crown Commercial Service) and NHS eInvoicing standards.

Through this collaboration, Transalis is not just a participant but an advocate for industry engagement.

Shape practical regulations:
Ensuring the final framework reflects the operational realities faced by businesses.

Helping businesses stay ahead by preparing early for potential regulatory changes.

Why eInvoicing? A step toward a smarter tax system

The UK is following the lead of several European countries that have already implemented eInvoicing to great success. Nations like Italy, France, and Poland have demonstrated that digital invoicing systems can:

Reduce tax fraud through real-time transaction monitoring.
Improve business efficiency by automating invoice processing.
Enhance compliance by simplifying VAT reporting, including pre-filled returns.

HMRC’s consultation reflects a growing global consensus: eInvoicing isn’t just about digitising paperwork; it’s about modernising financial processes to foster a more transparent, efficient, and fraud-resistant tax environment.

What comes next? Key dates to watch

The consultation period will run until May 7, 2025, after which HMRC will review submissions and develop a proposed framework. Here’s the anticipated timeline:

February: May 2025: Public consultation.
June: October 2025: Framework development based on industry feedback.
November 2025: Proposed eInvoicing regulations announced in the Autumn Budget.
2026 to 2029: Technical development, testing, and pilot programs.
2030: Potential full mandate rollout across UK businesses.
