NHS organisations can be pre-authorised so that they don't have to waste time trying to produce types of evidence that are normally required.  If an organisation is registered with the NHS Address Registration Service, their application for a Certificate could not be simpler. All that is needed is an NHS Organisation Code and a Purchase Order Number. NHS personnel will vet the application and process the request and then Trustis will do the rest, including making your certificate and sending you an invoice.

You can buy either a 1 year, 2 year or 3 year certificate, singly or in bulk, in Single-Site or Wildcard form.
