Our Accreditations are changing in line with the new requirements coming in from April 2026.
Following the announcement in The Finance Bill 2026 of Joint and Several Liability these arrangements will be caught by the new legislation.
Our new accreditation, as part of the protection process for Joint and Several Liability, will require use of the Fortis system for the payment validation of all workers.
Accreditation will be achieved once a provider (1) has satisfied our review of a provider’s operational processes and procedures, and in addition (2) is integrated into our new Fortis platform.
We will be migrating existing providers to Fortis towards the end of 2025 and early 2026.
With effect from the start of the 2026-27 tax year, previous accreditations of providers who are not integrated into Fortis will cease to be valid.
