Mediapolis has been appointed to handle the entire Thompson Travel Group media business in a winner-takes-all pitch against fellow incumbent, MindShare.
Mediapolis already has £7 million of Lunn Poly business, an account it has handled for around 14 years. The latest win adds £15 million-worth of Thomson Holidays business to its portfolio. Thomson spent £9.5 million last year through MindS hare.
The move to consolidate the business into one agency reflects the Group's strategy of working more effectively as a single business.
Up to now, activities surrounding the separate brands have been disparate across all functions from IT to marketing. The brands include core operations Thomson, the UK's biggest tour operator; Lunn Poly, the UK's leading travel retailer and Britannia Airways as well as smaller brands such as Simply Travel, Portland and Skytours.
Mediapolis' managing director, Marc Mendoza claimed: "The efficiencies within media are obviously quantifiable and we are pleased that TTG believes we can deliver excellent value."
Shaun Powell, managing director of Thomson Holidays added: "The aim of centralising both Thomson Holidays and Lunn Poly into one agency is to ensure that both businesses are buying and planning media as effectively as possible, at the best possible value."
The group recently announced some sweeping changes aimed at reversing its fall in profits. It is investing £100m in developing its internet sales and much marketing activity will centre around its new sites such as latedeals.com and online supermarket First Resort.
A company spokeswoman said there were no plans to review creative agencies at the moment.
