What is UK e-invoicing (Peppol, planned) in United Kingdom?
The UK ran a public consultation on e-invoicing and digital reporting in 2025 and has since confirmed it intends to make e-invoicing mandatory for VAT invoices, with Peppol named as the core interoperability network. Public reporting points to a mandate from around April 2029 for B2B and B2G VAT transactions, but the full technical specification, format rules, and phasing are still to be published.
That does not mean there is nothing to do. Peppol e-invoicing already works in the UK voluntarily (the NHS has used it for years), and many of your international customers and suppliers already expect it. Getting Peppol-ready now means you trade more smoothly today and you are not caught in the rush when the mandate firms up.
We build to the EN 16931 standard and the Peppol network, so your readiness work holds its value whatever the final UK specification says.

Dates and thresholds change, and scope depends on your exact situation. Treat this page as a starting point, confirm the detail with the HM Revenue & Customs (HMRC), and tell us what you run today, we will tell you plainly what an integration would involve.
Built into the software you already run.
Because the UK specification is not final, we build to the stable foundations: Peppol and the EN 16931 standard. That makes you compliant with what already works, useful for trading today, and quick to adapt when HMRC publishes the detail.
If you trade with the EU or supply the public sector, the readiness work pays off immediately, not just in 2029.
United Kingdom e-invoicing questions.
Is e-invoicing mandatory in the UK yet?
Not yet. The government has confirmed it intends to make e-invoicing mandatory for VAT invoices, with Peppol as the core network, reported as from around April 2029. The detailed specification and phasing are still to be published. Confirm with HMRC.
If it is not mandatory, why act now?
Peppol e-invoicing already works in the UK voluntarily and many international and public-sector partners expect it. Getting ready now smooths trade today and avoids the deadline rush later.
What standard should I build to?
Peppol and the EN 16931 standard, the stable foundations the UK is expected to build on. That keeps your readiness work valuable whatever the final specification says.
Can you integrate Peppol with my software?
Yes. We connect your existing ERP, accounting, or billing software to a Peppol Access Point, and we also build compliant systems from scratch.
