The United Kingdom changed course in November 2025: following the consultation it is decided to mandate e-invoicing for all VAT invoices — between businesses and towards the administration, not towards consumers. ⚠ The legislation and the implementation roadmap are still outstanding; the latter is announced for Budget 2026. Until then there is nothing to do, but the deadline is set.
