On Thursday 21st August we took to the high-footfall streets of Westminster in London to launch a fast-paced, high-energy FMCG street sampling activation for the new McVitie’s Orange Club Layers biscuit.
Instead of waiting for consumers to find the new Mcvitie’s Club Layers on supermarket shelves, the campaign focused on a direct sampling takeover. The mission was clear: generate immediate brand awareness and drop 10,000 bars directly into the hands of a prime city demographic.
To cut through the noise of a bustling central London environment, we deployed a highly visible, nimble mobile sampling bin setup. Rather than being tied down to a single fixed location, the team roamed fluidly across Westminster’s busiest pedestrian hubs and transit routes, meeting city workers, shoppers, and commuters exactly where they were.
The activation used simple, high-impact branding to draw crowds quickly:
A fast-moving 8-hour live activation window (11:00 AM – 7:00 PM) was designed to catch the peak lunchtime rush, mid-afternoon snack cravings, and the heavy evening commuter footfall. The team structure consisted of:
The strategy centered on a highly fluid field marketing model, leveraging striking corporate color blocks and mobile merchandising units tailored for instant visual recognition. Over a continuous eight-hour operations window spanning midday and evening rushes, a dedicated group of six brand ambassadors and an on-site manager achieved an absolute stock clearance of 10,000 full-sized bars distributed directly to passersby.
By prioritizing direct physical interaction over passive advertising, the campaign paired the massive mainstream recognition of the McVitie’s name with an approachable, high-energy street presence that connected seamlessly with city workers and shoppers aged 18–45. Securing 15,000 consumer touchpoints and thousands of active flavor trials on an efficient total spend of £4,791.30, the project illustrates how lean budgets can generate major brand tracking when meticulous execution backs a clear creative vision.
“This field strategy proves how effectively an FMCG product can penetrate a crowded city centre relying on energetic staff, distinct branding, and an agile distribution style that leaves no waste. It bypasses the fluff to drop product trial right where the audience lives and works,” said David Gibbons, Managing Director at iMP.
By focusing on high-velocity hand-to-hand distribution and a lean operational model, this campaign delivered a massive return on investment, proving how effective a targeted, budget-conscious street activation can be for an FMCG launch.

While costs vary based on logistics and uniform requirements, a streamlined street activation – like our McVitie’s Westminster campaign – can achieve an incredibly efficient cost-per-sample. With a total budget of £4,791.30 to distribute 10,000 units, the cost per physical sample was just under £0.48. This budget structure covered six brand ambassadors, full event management, bespoke branded kit, and eight hours of continuous live deployment in central London.
For a high-velocity urban activation, we recommend a squad of six professional Brand Ambassadors led by a dedicated on-site Event Manager. Operating over an eight-hour window (11:00 AM to 7:00 PM) across busy pedestrian zones, this team size ensures a distribution velocity of roughly 200 bars per ambassador per hour. This allows the team to easily clear 10,000 units while maintaining high-quality consumer engagements.
Roaming, mobile sampling campaigns are highly versatile because they don’t rely on a fixed experiential footprint. However, compliance rules vary significantly across London boroughs. In high-footfall areas like the City of Westminster, strict guidelines govern street distribution and clean-team waste management. Our team handles the entire operational compliance and permit process, ensuring all roaming routes, team sizes, and branded assets strictly adhere to local authority regulations.
We track two core performance metrics alongside total stock distribution: total touchpoints (interactions) and deep brand engagements. For instance, during our Westminster sweet-biscuit activation, our team generated over 15,000 total visual and verbal touchpoints with pedestrians, which translated into 10,000 deep, high-quality engagements where consumers actively learned about the new product’s flavour profile while receiving their sample.

We partnered with iMP Sampling & Experiential for a summer campaign with one of our clients, and we couldn't be happier with the results. They executed a total of 42 in-store events nationwide, and their team's expertise in sampling and experiential marketing truly shone through. The staff were great at engaging with customers and helping us to achieve our goal of increasing footfall and participation at each event.

We worked with iMP on stands for two different events and were thrilled with the quality of the items we received. The team executed our brief to a fantastic standard, working to a tight turnaround to deliver all materials required for both events, and were extremely supportive and quick to respond to any questions we had throughout the process. Thank you iMP for your work on this project to ensure we had incredible activations at both of our events!

Hiring iMP for an event I was leading on for a new client was a great decision. They turned around a high quality sampling event and promo vehicle with a very short turnaround time, and their staff on the day were incredibly enthusiastic and professional. They made the process easy and the client very happy, we'll definitely be working with them again.
