The UK’s advertising marketing is undergoing record growth, with spend expected to reach £32billion in 2022. So, how do you go about choosing your next advertising agency?

The UK’s advertising marketing is undergoing record growth, with spend expected to reach £32billion in 2022. 

That comes following 26.4% growth in 2021 - that’s according to the latest Advertising Association/WARC Expenditure Report

Should the figures for 2022 be correct, the UK market will have expanded by more than a third since 2020.

So, with all that investment, which are the best advertising agencies in the UK? 

Well, first up, the “best” advertising agency for one brand or organisation, may not be the perfect fit for another. That’s why it’s worth looking through the case studies on Brands & Agencies to check out which advertising agency is right for you.

For some, the global giants will be the best, for other, a more niche, smaller agency will do the perfect job.

Globally, the big 5 ad agencies are WPP, Omnicom Group, Publicis, Dentsu and Interpublic Group. All of which have offices in the UK.


WPP owns some of the biggest names in advertising, such as Grey. Based in London, it employs more than 130k staff around the world, with revenues in excess of $17bn.

Grey works with Pringles, P&G,Volvo, Vodafone, Braun, Coca-Cola and HSBC, among many others. Over the years it’s been Global Agency of the Year twice.

Meanwhile Ogilvy was named as WARC’s most creative agency network for the second year running. The ad agency was founded by David Ogilvy in 1948 and now has 131 offices in 83 countries.
