Supplier Spotlight – PF Concept

PF Concept stands as a beacon of reliability and innovation in the promotional merchandise industry, with a heritage tracing back to 1973. As a founding pillar of the Polyconcept Group, PF Concept has evolved into Europe’s largest supplier of promotional products, supporting distributors and brands across the UK and Europe. Headquartered in Roelofarendsveen, the company boasts nine dedicated sales offices throughout Europe, a state-of-the-art warehouse and certified printing facility in Poznań, Poland, and in-house manufacturing of innovative products in the UK. This extensive infrastructure underpins their 50-year reputation for delivering quality, expertise, and service excellence to partners of all sizes.

Expertise in Product Media and Customisation

PF Concept’s unrivalled product media expertise is evident in their comprehensive collection of quality products and premium brands, spanning categories from drinkware and technology to clothing, bags, stationery, and more. Whether clients are seeking cost-effective giveaways or high-end executive gifts, PF Concept offers depth of choice at every price point. Their “Create Your Own” and bespoke programmes empower clients to tailor products precisely to their branding needs and campaign objectives, with dedicated sourcing and extended customisation options. Products are selected and designed “with care”, prioritising durability, on-trend aesthetics, and a brand-led approach that keeps the client’s identity – not the supplier’s – at the forefront.

Digital Tools and Sales Support

In today’s fast-moving market, PF Concept enables distributors to respond rapidly to opportunities with advanced digital tools, deep inventory, and swift branding processes. Their robust web shop and digital catalogues streamline the ordering journey, while sales experts provide inspiration, product knowledge, and practical support to help clients win business. These capabilities save valuable time, reduce administrative burdens and artwork rework, and allow distributors to focus on selling products – like the Promotional Slender 4 Mah Power Bank – that make brands and people proud.

Commitment to Sustainability and Ethical Practices

PF Concept is committed to reducing its environmental footprint across the entire supply chain, setting clear targets and publishing transparent progress through their annual Sustainability Report. Their ambitious “Rethinking Plastics 2030” strategy aims to phase out all virgin fossil-based plastic products and packaging by 2030, focusing on innovation, circulation, and elimination of plastics. The company’s circular design approach incorporates sustainable, recycled, and bio-based materials, enhanced recyclability, and product longevity, with GRS-certified ranges and Aware™ traceability technologies ensuring supply chain transparency. External recognition – such as an EcoVadis Platinum rating and a multi-year partnership with UNICEF the Netherlands’ “Plastic Bricks” programme – validates their leadership in social and environmental responsibility.

Ethical practices are at the core of PF Concept’s operations. The company enforces robust modern slavery and anti-slavery policies, adhering to the Modern Slavery Act 2015, conducting regular audits, providing staff training, and maintaining a dedicated compliance team. PF Concept UK also publishes gender pay gap data via the UK Government’s reporting service, underlining their commitment to transparency and pay equity.

Stakeholder Engagement and Waste Reduction

PF Concept recognises that stakeholder engagement is vital in reducing waste within the promotional merchandise sector. Branded products often cannot be repurposed or rebranded without careful planning, so PF Concept encourages clients to create awareness around returns, misprints, and over-ordering. Through clear guidance and collaboration, they help clients minimise unnecessary CO₂ emissions linked to wasted stock and logistics, improve forecasting, and extend product use – ultimately reducing the volume of merchandise that becomes obsolete.

Circular Economy and Reuse Partnerships

Putting circular design principles into practice, PF Concept designs products for longevity and repair where possible, favouring materials and constructions that support recyclability at end of life. Their partnerships with organisations such as Reshare and local groups in Poland ensure that surplus textiles or products unsuitable for branding are donated or repurposed instead of being sent to landfill. These initiatives support a circular economy, reduce environmental impact, and provide clients with credible end-of-life options for campaign stock and uniforms.

Inspiring Change and Building Trust

PF Concept’s comprehensive approach – spanning product quality, innovative customisation, digital selling tools, sustainable practices, and ethical standards – builds enduring trust with clients and their stakeholders. The benefits are tangible: enhanced brand reputation, stronger corporate social responsibility narratives, smoother internal approvals, and potential cost efficiencies through reduced waste and better product longevity. By championing subtle, quality branding and well-chosen products that people want to keep and use, PF Concept helps clients maximise impact per item, supporting both environmental and commercial goals.

With over five decades of expertise, a relentless focus on innovation, and a deep-rooted commitment to sustainability and ethics, PF Concept is the partner of choice for forward-thinking brands and distributors seeking to inspire, engage, and make a positive difference – one product at a time.
