The data presented in all the charts derives from a questionnaire published on Design Week’s website, www.designweek.co.uk, from January onwards and highlighted in print and online. All readers and site visitorswere invited to take part and submit figures for the 12 months from January to December 2010.
All figures published have been verified by an independent auditor’s statement submitted by the consultancy and signed off by a consultancy director.
The bulk of the Top 100 comprises independent groups.Consultancies owned by global marketing services groups such as WPP, Omnicom, Havas and Interpublic Group are unable to present figures that haven’t undergone a full audit, under the terms of the Sarbanes-Oxley Act in the US.They are therefore ranked separately in charts based mainly on 2009 figures registered at Companies House. The Top 100 is based on design fees billed through consultancies’UK office. These do not include income fromprinthandling, property, shopfitting and the like,which is covered by turnover.The ranking takes no account of physical size, which features in the staffing tables, nor does a place in the chart reflect a group’s creativity. Consultancies are also ranked by market share and design specialism following the same principles.
There have been more entrants into the trawl this year, which puts the baseline for inclusion at £738 000 in fee-income.
The data has been analysed by accountant Amanda Merron at Kingston Smith W1,which also compiled the charts of groups owned by global networks from submissions to Companies House.
