AJ100 Survey 2025

Established in 1995, the AJ100 survey is the definitive annual record of the UK’s largest architecture practices measured by the number of architects employed in the UK.

The accompanying AJ100 Awards programme celebrates the achievements of these firms, focusing on those leading the way on climate action and driving positive change in the profession.

The survey is divided into two parts:

Part A – Practice data

Part B – Awards

For details of how to save your answers as you go along, please see the 'Frequently Asked Questions'.

IMPORTANT - while it is possible to save your answers as you go along, once the survey has been completed and submitted, you will not be able to edit your submission.
