The United Kingdom named April 2029 and chose Peppol
· Diese Seite wird auf Englisch bereitgestellt.
On 28 October 2026 the British government published a roadmap for electronic invoicing and put the date at 1 April 2029. It names Peppol as the network, leaves scope and exemptions to later regulations, and carries no clearance step and no real-time reporting in its first version.
Price Double Check reads an invoice against the price list it should have been billed on and answers by email with the lines that disagree. A roadmap decides how a document travels and decides nothing about the figure printed inside it, and the distance between those two is where a buyer's work goes on sitting.
What was published on 28 October
The document is a joint publication of the tax authority and the business department, released with the Autumn Budget, and it is a timetable of decisions rather than a set of rules. Its own sentence is that it sets out the timeline for key decisions the government will make to enable businesses and organisations to adopt electronic invoicing from 1 April 2029.
Two choices in it are already made. The first is the network: the United Kingdom will adopt Peppol as the core interoperability framework, which puts it on the same rails as most of the European mandates rather than on a national portal of its own. The second is the restraint. The first version is electronic invoicing and nothing else, with a separate consultation on the future use of digital reporting running until 20 January 2027 before any of that is decided.

What it changes for a buyer
Less than the headline suggests, and the part that does change is the part nobody prepares for.
- The receiving side moves first in practice, whatever the drafting says. Being able to take a structured invoice off a network and read it is the capability a purchasing desk needs, and it needs it before the first supplier switches rather than on the date in the regulation. Doing that without an accounting system to put the documents in is its own small problem: receiving Peppol invoices without an ERP covers it.
- Price lists are untouched by all of this. Mandates reach invoices, and the document a buyer compares an invoice against goes on arriving as a spreadsheet or a PDF attached to an email, before 2029 and after it. Half of every comparison therefore gains nothing from the network.
- The dangerous week is the one a supplier migrates in. A new invoicing system is when item codes acquire suffixes, when descriptions are rewritten and when a line stops joining to its row in the price list. The code is the only key that works, and a code that changes in the move breaks a comparison without raising an error.
- Two and a half years is long enough to do nothing yet. Scope and exemptions are not published, so a buyer who builds against today's draft builds twice. The wider direction, and which countries arrive before this one, is in PDF invoices are going away.
One question is worth asking now, of every British supplier, and it costs nothing: when do you intend to switch, and do your item codes survive the move unchanged. The second half of that question is the half that matters, and it is the half almost nobody asks.
Forward one invoice and the price list it should have been billed on, in whatever form each of them turns up in, and the comparison comes back by email naming the lines that differ. A structured document and a scanned PDF get the same arithmetic. What a check costs is on the home page.
