Sleek announces its new ISO certification

Full-service, experience marketing agency Sleek, today announces it has achieved ISO14001:2015 and ISO20121:2024 certifications from the British Standards Institution (BSI), underscoring the agency’s commitment to sustainability and responsible business practices.

The certificates are valid until 5 March 2028, a marker for the agency to maintain its high standards in environmental management and sustainable event planning.

This is not a one-off achievement: certification requires annual assessments, ensuring Sleek remains accountable and continually improves its practices year after year. It’s an ongoing process that reflects the agency’s serious approach to embedding sustainability throughout the business, not just in principle but in practice.

Gabriella Weekes, Supplier & Sustainability Lead at Sleek says: “Sustainability isn’t just a box tick at Sleek, it’s a commitment embedded in our DNA. Our strategy focuses on driving meaningful change, from combating climate change to promoting social equality. This achievement is a reflection of the dedication and hard work of our team. We are committed to continually raising the bar when it comes to responsible practices and making a lasting, positive impact through every event we create.”

Jennifer Davidson, at Sleek adds: “When sustainability became a business buzzword, I was reluctant to adopt it for the sake of a trend. I believe meaningful change only happens when everyone is truly on board, not when it’s dictated from the top down. So, we began by asking ourselves: What does sustainability mean to us? Why does it matter? That reflection laid the foundation for our journey – one built on clear, SMART goals that influence every part of the business and pave the way for a future where we can genuinely make a difference.”
