# United Kingdom — Making Tax Digital, NHS Peppol & e-invoicing consultation

MTD VAT reporting universal · NHS Peppol B2G · No general B2B mandate — regulator: [HM Revenue & Customs (HMRC)](<https://www.gov.uk/government/organisations/hm-revenue-customs>). _Facts last refreshed: 2026-07-13._

Coverage model

Flowie operates a registered Peppol Access Point in this jurisdiction **directly** where we hold national accreditation, **or via a vetted local partner** registered with the in-country regulator where on-the-ground presence is required (KSeF, SDI intermediario, ZATCA service-provider, etc.). Either way, you call the same `POST /v1/documents/send`. 

## TL;DR

  * **Making Tax Digital (MTD)** for VAT is universal — every VAT-registered UK business submits quarterly VAT data via API.
  * **NHS Peppol mandate** (PEPPOL) requires healthcare suppliers to use Peppol BIS for NHS B2G since 2021.
  * **No general B2B e-invoicing mandate** ; HMRC consultation closed February 2025, results expected during 2026.
  * Cross-border: Peppol BIS via Flowie's UK AP.



## Deadlines

Date| Who| What  
---|---|---  
2019-04-01| All VAT-registered UK businesses| MTD for VAT launched.  
2021-04-01| NHS suppliers| Peppol BIS mandatory for NHS England trading.  
≥ 2027| General B2B mandate (under consultation)| HMRC reviewing — Italy-style or France-style framework not yet selected.  
  
## Background

The UK is in flux. MTD has digitised VAT _reporting_ for years, but the underlying invoice can still be paper. The 2025 HMRC consultation on full B2B e-invoicing closed in February with high response volume; the government is now sifting between a France-PDP-style decentralised model and an Italy-SDI-style central clearance model. A decision is expected during 2026.

In the meantime, NHS Peppol (often just called PEPPOL within the NHS) is the most mature B2G regime — every supplier to NHS England must transact via Peppol BIS.

## Format profile

  * **Peppol BIS 3.0** for NHS B2G and cross-border.
  * **MTD VAT JSON** for HMRC quarterly returns (separate from invoice format).
  * UK VAT: `GB` \+ 9 digits.

## FAQ

### Will the UK adopt the EU's ViDA framework?

Unclear. Post-Brexit, the UK is free to chart its own course; HMRC has been studying both EU and non-EU regimes (Australia's Peppol-by-default, Singapore's InvoiceNow). The 2026 decision will reveal which way they go.
