We've been creating memorable ideas and campaigns for a long time; in fact, we opened our first office way back in 1957.


Shortly after, we aired the first live-to-air TV advert, but that's where the history lesson ends. All our work and strategic expertise focuses on tomorrow, not yesterday.


Our team includes published authors, award-winning bloggers, radio pundits, passionate film-makers, data specialists, perfectionist planners and creative brains from all walks of life. We work hard, but we also pride ourselves on our fun and friendly culture.


Having such a varied team of specialists in everything from Advertising, Media, PR, B2B Marketing, Shopper Marketing, Experiential, Brand Activation and Social, to Direct, Data, Insight, Analysis and Content, means that we can always hand-pick the right people to tackle your specific challenge, whatever that might be.

"Having worked with the team at Golley Slater over a number of years, they have become an extension of the integral marketing function at Linde Material Handling and are an absolute pleasure to work with. With a comprehensive understanding of the marketplace in which we operate, they need little direction in ensuring we maintain our presence in the key trade press and on-line. The team are extremely organised, providing regular, detailed updates on activity, budget and reporting on coverage. We would not hesitate in recommending Golley Slater."


"An excellent agency to work with. They are highly experienced with an unmatched knowledge of the media landscape particularly here in Wales. All of our work with them has delivered impressive results and they are extremely professional, patient, reliable and actually fun to work with. If an agency aims to be an extension of a client team, then Golley Slater achieves this."

"We'd like to thank Golley Slater for all their work in helping us with our information awareness campaign. They were very helpful and personable, ensured we met the deadlines and were on brief and came up with additional channels that we hadn't even thought of that were still cost-effective. They're excellent value for money compared to other agencies and our campaign yielded great results with some even beating industry standard rates. We'd recommend this agency to others."
