Top London Agencies: Q2 2021

June 3, 2021

Today, London is one of the world’s largest advertising and media hubs. In fact, ad agencies in the city are responsible for roughly 80% of the income generated by the UK’s advertising market. The majority of UK firms are headquartered in the capital city and contribute £100 billion to the national economy. But, what draws top talent to London agencies?

To start, access to international brands. In recent years, UK agencies created effective global branding for HSBC, Samsung, Virgin Airlines, Hilton Hotels, Audi, Emirates, AUDI, Huawei, and Air New Zealand. And, the city’s international reputation is largely due to its time zone. Poised between East and West, London agencies work comfortably with almost any other city in the world. Above all, GMT is highly convenient for global organizations.

London’s regulatory and business environment support good business practices, too. Subsequently, there’s a flexible labor market and responsible marketing that still encourages creativity, innovation, and entrepreneurialism. The UK is also home to the notoriously rigorous  IPA Effectiveness Awards. Therefore, according to their website:

Every two years, The IPA Effectiveness Awards celebrate and showcase communications agencies, media owners or advertisers that successfully prove that their work achieved outstanding results. Then, entries form part of a permanent database of Effectiveness Case Studies that become a uniquely credible resource for anyone looking for examples of commercial creativity that works.

To find your perfect fit, we uncovered 38 of London’s top marketing and advertising agencies. Our list is compiled of agencies with a client media spend of at least $100 million (£70,675,000) in Winmo.
