Welcome to the 2018 IIM Interim Management Survey, the Institute's annual assessment of interim management and service providers (agencies). This year, as well as the Provider Rankings, we are exploring Interims' confidence in the market and of course the area of IR35. We hope that you enjoy participating and seeing the survey results in due course.

Survey Timing

The survey opens on May 1st at 00:00am and closes end of May 31st at 23.59pm
The survey is published on July 2nd from 8.00am, at

We think the survey will take around 20-25 minutes.

This survey is only for professional interim managers and executives to complete (defined as an independent professional operating at board or near board level on day rates of £450+.)  If you are a contractor (sub-£450), a prospective interim manager, an interim service provider or client, then we have no questions for you at this time (but thanks for coming by).

Confidentiality and non-spam

For your reassurance, individual answers are completely confidential (just as well as we'll be asking some detailed questions) and the survey is spam-free. Contact details are not captured at any point as 'e-mail harvesting' is not what we do.
On with the survey...
