Our current clients:

RSPCA - Animal Life magazine


Terry has been a great asset to the RSPCA's animal life magazine for more than 15 years. He never fails to impress us with his enthusiasm and ideas, and shows a good understanding of our very specific requirements. Consequently we are able to produce a good quality magazine with articles and advertising that is relevant and interesting to our readers.

Over the past 15 years TLMS has brought a professional approach to New Internationalist advertising. Terry and his team bring solid experience and a substantial working knowledge of the industry and I would have no hesitation in recommending them to any magazine seeking to increase their advertising sales.

Marketing Director
New Internationalist

With charity clients being our specialisation it’s essential that on the media- owner side we have people like Terry who understand the charity marketplace. I have been doing business with Terry for over 15 years during which time he has represented numerous specialist titles and many charity ‘house’ membership magazines. I have always found him a pleasure to deal with; efficient, helpful and extremely knowledgeable about the charity sector and media landscape generally.
Terry is an essential part of my business.

I have known Terry for many years and he has always been, unfailingly, efficient and helpful. He is quick to spot new opportunities for my clients and will work hard to implement any ideas or proposals we may have to increase the efficiency of our ads or inserts.
