About One Day Agency
One Day Agency describes itself as an integrated advertising and marketing agency that bridges creative, digital and media, headquartered in Manchester on Cross Street. It says it started from a standing start in Manchester in 2019 and now has offices in London, Warsaw, Paris and Berlin. It calls itself a Drum Recommended agency and a Top 50 Integrated Agency for 2023, and the site also mentions a global biddable agency award, all as its own statements.
The service list runs across channels. Creative and digital ads cover paid social, YouTube, Spotify audio and other digital ads. Digital media covers Google and Bing Ads, search and shopping, and social advertising. Out-of-home covers billboards, three-dimensional billboards, airport, bus, bus stop and Underground advertising, building wraps and tourist buses. TV and video on demand covers broadcast, ITV and Channel 4 streaming, Sky AdSmart and app-based services, and audio covers radio and the DAX network. It says its media planners use proprietary planning software, and it has pages on AI ad creative and on advertising in ChatGPT.
Its blog is unusually specific about money, though about media and not its own fee. One post says billboard costs run from roughly £200 to over £5,000 for two weeks, depending on location, timing, format and whether the board is paper or digital. Another suggests starting a multi-market campaign with 25% to 40% of working media budget in out-of-home and 60% to 75% in digital, as a planning range to adjust. A third explains how to test whether out-of-home drove web traffic with a geographic incrementality test. No agency fee, minimum budget or contract length is published.
Named work includes a September 2026 appointment by Collection Cosmetics to lead its UK media and creative activity, and clients quoted on the home page include UNiDAYS and BigCommerce. Case studies cover retail performance marketing, a motorsport experiential campaign and an international technology out-of-home campaign, without figures on the pages read.
Ask whether the agency charges a fee, a commission on media bought or both, who the planner on the account would be, and whether the proprietary planning software is shown to clients.
