How this list is made

Listings come from the Assurix Trustmark Directory, as at 14/11/2026. Assurix sets each provider’s status. Towns, sectors, certificates, founding year and staff numbers are what the provider lists. Providers working with Assurix pay a subscription. None of them can change a result, and an Assurix assessor signs off every Trustmark.

Grouped by status, in alphabetical order within each, so every Assurix Trusted MSP is shown equally. Reviews and payments play no part in the order. Assurix Trusted and On the Journey providers are Assurix customers whose status Assurix checks, which is why they come first. Committed providers have signed up with a start date booked.
