Republic Marketing was referred to us by one of our clients, and from the first conversation, it was clear we were in safe hands. They took the time to understand our business, what sets us apart, and how to reflect that through a modern, professional website. The result speaks for itself. We’ve had brilliant feedback from clients and suppliers, and it genuinely feels like an extension of who we are. The site is clean, easy to navigate, and built to last. We’re now working with them again on our commercial division and wouldn’t hesitate to recommend them.

We had a brilliant experience working with Sajad. Incredibly knowledgeable, clear, and generous with advice, he genuinely knows what he's doing and explain things in a way that makes you feel confident and supported. The insights we received were sharp, actionable, and tailored to our business. Highly professional, no fluff, just real value. Would absolutely recommend to anyone looking to get serious about their digital marketing.

Norsu solved our website issues really quickly. We had some malware or something on our Wordpress site that we think was stopping us ranking. It kept redirecting to spam sites. Tom and his team quickly came in, diagnosed the issue and got it sorted for us. Thank you so much!!

eCommerce Development Review from Tanushree Panda
We recently enlisted Heseven to redesign our Shopify store, and the results have been phenomenal. Their team took the time to understand our brand and vision, transforming our outdated website into a sleek, modern, and user-friendly shopping experience. The new design is not only visually stunning but also highly functional, improving our sites navigation and overall user engagement. Heseven's expertise in Shopify is evident, and their attention to detail is unmatched. The project was completed on time, and they kept us informed throughout the process. We highly recommend Heseven for any Shopify design and development needs!

I have recently completed 10 ADHD Coaching sessions with Chris Talintyre - I can't thank him enough for all that he has done and supported me with. I have been able to implement so much from the work we have done together, I have grown in confidence and so grateful for all the support and guidance he has given. I cant recommend enough! Thankyou Chris!

Beth Mawdsley's Review Sourced from Google
Chris changed my ways of working tremendously during our coaching sessions. Every barrier I was facing Chris found solutions that were easy to implement and use moving forward.We had great discussions every session and Chris always picked up on little details in what I was saying and was able to find the most amazing information to send over which I not only found useful for myself but was also able to share with my colleagues who also found the information very useful. In all honesty I didn't want my sessions with Chris to end! I started our sessions with low confidence and a bit of a mess in my head as to the structure of my working day and I came out with clear plans and strategies thanks to Chris. I highly recommend Chris's coaching sessions. Thank you so much!

Imogen Aitchison's Review Sourced from Google
Adding to my 5* review from 4 years ago to add that Atomic have continued to provide invaluable advice and support. They are very responsive and great at problem solving. Still 🌟🌟🌟🌟🌟 in 2025!I got quotes/design ideas from several agencies for my website. Atomic stood out from the start. They listened to what I wanted and produced a very comprehensive, detailed and competitive plan. They understood my needs as a small business owner and delivered exactly the aesthetic I was after. They were also incredibly patient with the many tweaks and changes needed along the way. They worked extremely hard to find solutions when challenges arose, their communication skills were exceptional and they were willing to train me up so I could make basic updates and changes myself. Very professional and approachable. I’m really glad I chose them!

Have work with Atomic now for over 7 months and I have to say that is the best Digital Marketing Agency I have worked with in my 20 years career. They are pros that know what they are doing, get things done and more importantly, deliver results. I would like to mention Simon, Rachel, Tim and Justin, thank you for your work and support always! 100% recommend them.

Paul Holden's Review Sourced from Google
We've been using Atomic Digital Marketing for web hosting and ongoing website maintenance, and they’ve always delivered a reliable and responsive service. Recently, they've supported us with some UI improvements and are now helping implement important compliance updates following our company’s acquisition. Special thanks to Timothy and Amr, who have both been incredibly helpful and supportive throughout – their attention to detail and quick turnaround times have made a real difference. Highly recommended.
