The UK e-invoicing roadmap lands at the Budget on 28 October 2026. Until then there is nothing to build against.
This page exists to stop you spending money nine months early. It is on the wall because the date matters, not because there is work to do yet.
Who it binds
- Eventually, all VAT-registered businesses. Businesses not registered for VAT are explicitly excluded.
- No size or turnover phasing has been announced. Claims that phase one is large-business-only are vendor inference, not policy.
What it actually demands
- Nothing yet, and that is the point.
- The government's commitment is that all VAT invoices must be issued as e-invoices "from 2029" — no month stated.
- No standard has been formally selected. Peppol was named in the June 2026 Tax Update as the core interoperability network and is heavily signalled, but the consultation response references it as respondents' preference.
- No legislation has been laid. Finance Act 2026 contains no e-invoicing provisions.
Buying a readiness assessment now means paying to be assessed against a specification that does not exist. The roadmap publishes at the Budget on 28 October 2026 and real scoping opens after it — realistically Q1 2027, which still leaves two years.
What it means for the estate
The work that is worth doing before then is not UK-specific: legal-entity identifiers, customer master completeness, VAT determination producing structured codes rather than free text. That work is already required by the French and German mandates, and it is the same data.
If you have EU entities, build for France and Germany now and the UK becomes a configuration change in 2028 rather than a programme.
