To Whom it May Concern' letter - Architects Registration Board

Sometimes, you may need to provide confirmation of your registration in the form of an official letter from ARB, for example, when submitting a competition entry.

We have a standard letter available which we can let you have on request, and we do not charge for this service. We will generally send these letters by email, unless you ask otherwise. These letters may take up to ten working days to produce at busy times of the year.

To request this letter please email us at or call us on +44 (0) 20 7580 5861.
