Managing third party authorisations on your account | Letter of Authority

What is a letter of authority?

Submitting a Letter of Authority for your Business Stream account allows you to give permission to someone else, a named third party, to access or manage parts of your account on your behalf. A third party could be your partner, an associate, a solicitor, your landlord or another company individual you contract with. To set up third party authorisation, you can send us a 'letter of authority' which officially advises us of your permission(s).

Request third party authorisation

1. Complete and sign our Third Party Authority form 
2. Attach your signed Third Party Authority form to the general enquiry form at the bottom of this page (Please select 'Third party access' from the drop-down menu. You'll see an option to upload your completed form on the second page of the form).​

Please note: You can choose submit your own letter‑headed Letter of Authority if you prefer. Whichever option you choose - your own version or the form provided above - will remain valid for three years.​
