Methodology and notes

Methodology and notes

More than 350 firms were contacted for this year’s Building Top 150 Consultants Survey, the results of which are shown in the tables above. They were sent a survey form asking for details on the number of chartered staff, non-chartered and technical staff, and domestic and worldwide fee incomes. Practices were also asked questions relating to: staff recruitment, wage patterns, margins, areas of work, and work expectations. 

All data in the tables are taken directly from firms’ replies. As there was no Top 150 survey published in 2020 for covid-related reasons, where a company is marked “new“ that means it was not in the 2019 Top 150 rankings.

The survey does not claim to list all the top consultants, as it relies upon firms completing and returning the annual survey form. For a variety of reasons, firms sometimes decide not to take part. Only those firms completing and returning the survey form are included in the survey.  Firms having any questions about the survey, or wishing to be included in the 2022 survey, should contact Martin Hewes at Hewes & Associates: www.hewes-associates.com.  

NB: “New” is used to mean that the company was not in the 2019 Top 150 consultants table.
