Salt is a strategic creative agency with a passion for health.
We offer clear, joined-up thinking that creates positive change. Nothing overcomplicated or unnecessary, just the fundamental elements developed into strong ideas and creative solutions that make a difference.
We believe in taking an honest, original approach to any challenge, considering all aspects to develop bespoke and compelling results that work.


We are only interested in work that achieves its objectives. Our strategists are experts in untangling powerful insights and identifying compelling direction across marketing, medical, brand and consumer challenges, to provide power for positive change.


With creativity running through our veins, we thrive on a creative challenge and love bringing ideas to life. Be it branding, conceptual, design or delivery, we pride ourselves on finding a new perspective and nurturing it into a finely-crafted and impactful end product that affects change.


With interaction and connectivity essential to making change happen, digital is at the heart of transformation. Our teams harness the latest innovations, providing uninhibited thinking to online campaigns, social, video, gaming, apps, websites and novel digital solutions. Designed specifically to suit the challenge, all our projects are efficiently tracked, managed and monitored to ensure they meet the hard and soft measures of success.

Behavioural psychology

Going way beyond ‘behaviour change’ advertising speak, we work with a team of certified behavioural psychologists – expert, evidence-based researchers who understand not just what people say, but what they think and how they feel. And, most importantly, why. This most powerful of insight allows communications to connect on a much deeper level, making them significantly more powerful and effective at creating change that lasts.

Founders / Chris & Kath

Chris and Kath are long-time friends and colleagues. With almost 40 years of combined experience in advertising, digital and communications agencies, they have developed a desire to end over-complicated ways of thinking, talking and working.
The result is Salt – an agency that offers straightforward, intelligent, creative solutions and follows clean, honest values.
They have joined forces with a select group of like-minded thinkers to create something that reflects their beliefs and outlook on life. Something they’re proud to call their own.

Everyone at Salt shares the core values of honesty, positivity and collaboration. All associates are hand-picked by Chris and Kath, offering bespoke, creatively-minded, expert teams that are nimble, flexible and tailored to your needs. Salt thinkers include:

Kath Cotton / Managing Director

Turning potential into reality is the motivating force behind everything Kath does. Whether it's an idea, a person or a brand, working with a team to pinpoint the most powerful force and bring it to life is what she gets excited about.

Chris Tredwell / Creative Director

When asked of his love of design, his answer is 'problem solving'. Creating well thought through, beautifully crafted, bespoke solutions to client problems to truly make a difference is what gets him out of bed in the mornings.
