E-invoicing compliance and regulatory updates - United Kingdom
Last reviewed: July 1, 2026
Electronic Invoicing in the United Kingdom
Is e-invoicing mandatory in the United Kingdom ?
E-invoicing is not mandatory for all transactions in the UK. However, in May 2019, the UK government adopted the EU Directive on e-invoicing for public procurement via the Public Procurement Regulations 2019 and retained this requirement after Brexit.
Who is affected?
For Business-to-Business (B2B) transactions, there is currently no mandatory e-invoicing requirement. The UK government has announced that an e-invoicing mandate will come into place in April 2029, with details to be provided in 2026. All public bodies involved in public tender procedures must be able to receive and process electronic invoices in line with the EU Directive standards.
Compliance requirements
Public entities must accept electronic invoices that comply with the standards set by the EU Directive.

What formats are required in the United Kingdom?
There are no specific mandated formats. However, when using the Peppol Network, invoices must follow the network requirements, such as Peppol BIS-format.
Archiving in the United Kingdom
What are the archiving requirements in the United Kingdom?
Organizations must retain VAT records for at least six years, or ten years if using the VAT MOSS service. These records can be stored on paper, electronically, or within bookkeeping software. Records must be accurate, complete, and readable.
Legal invoice
- For suppliers: The legal invoice is the version sent to the recipient in the format the recipient receives. If sent via email, the email is considered part of the legal invoice.
- For buyers: The legal invoice is the version received from the supplier in the original format sent. If sent via email, the email is also considered part of the legal invoice.
