About Us

How One Day Agency can help your FMCG brand.

More than ever, FMCG purchase decisions are driven by seamless consumer journeys, both online and offline. Attention is fragmented, retail is increasingly digital, and competition is tougher than ever. To win, brands need to combine bold creative with strategic media buying that meets consumers where they are: at home, on the move, and in-store.

As a top 50 UK integrated agency, we work with FMCG brands across food and beverage, household products, beauty and personal care, and lifestyle goods. Our campaigns stretch across every channel, helping brands build long-term awareness while also driving measurable sales.

Consumers.

For FMCG brands, consumers are often making impulse decisions within seconds. Winning their attention means being present in the right place at the right time – whether that’s a striking OOH ad on their commute, a TikTok campaign they share with friends, or a retail promotion right by the checkout.

We use data-led insights to build consumer segmentation strategies that go beyond demographics. We identify purchase occasions, lifestyle habits, media consumption patterns, and even regional buying behaviours. This allows us to craft campaigns that not only reach your audience but resonate deeply and drive repeat purchase.

From building national brand love for household names to helping challenger brands carve out market share, our consumer-first planning ensures your products don’t just get noticed – they get chosen.

Shopper & Retail Ecosystems

The FMCG battle is often won or lost at the point of sale. That’s why we integrate retail media and shopper marketing into every strategy we build. Whether your products are sold in Tesco, Asda, Boots, or Amazon, we make sure your brand stands out when consumers are closest to purchase.

Our approach combines in-store advertising, POS activations, digital screens in supermarkets, and programmatic retail media placements with brand storytelling across broader channels. This ensures your campaign doesn’t just raise awareness – it actively converts shoppers.

We also help brands align their advertising with retailer priorities and category plans, strengthening your relationships with buyers and boosting sell-through rates. By connecting brand marketing with retailer performance, we turn visibility into lasting distribution gains.
