1. Kinsman and Co
Address: Senna Building, Gorsuch Pl
Phone: +44 20 4602 5021
Business hours:
- Monday to Friday: 9 AM – 5:30 PM
- Saturday to Sunday: Closed
Kinsman & Co is comfortably operating at a higher tier, without making things overly complicated. The fact that they’ve worked with brands like Chanel, Dior, and Hard Rock Hotel sets the tone right away.
These brands are deeply focused on image and consistency, so the trust didn’t happen by accident. That positioning is supported by their win as Bespoke Full-Service Media Agency of the Year at the 2025 SME Business Awards.
We especially found their paid advertising service really impressive. Clients consistently mention strong optimisation, clear tracking, and campaigns that actually convert.
Their team is also very hands-on. The feedback we’ve heard highlighted smooth processes, thoughtful suggestions, and a genuine effort to understand the brand.
Their content work also stands out. They do video production, social content, and podcasting in a high-quality way. They’ve elevated websites and social channels.
Their pricing model is retainer-based and flexible. It’s shaped around media spend and actual needs rather than fixed packages.
That’s a plus for brands looking for a tailored setup, but it also means this isn’t a bargain agency.
Based on this, we think they’re less suited to smaller businesses seeking the lowest possible cost.
Their professionalism and expertise are evident in every aspect of their work
“I am thrilled to share my experience working with the Kinsman & Co team. Their professionalism and expertise are evident in every aspect of their work. From the outset, they have been incredibly attentive, and ensuring that every detail is meticulously handled. Their commitment to excellence shines through in the high-quality production and seamless execution of each episode and social content piece…”

2. The Good Marketer
Address: 20-30 Whitechapel Rd
Phone: +44 20 3576 2150
Business hours:
- Monday to Friday: 9 AM – 7 PM
- Saturday to Sunday: Closed
The Good Marketers’ approach points toward small and medium-sized enterprises (SMEs) that want proper support.
One of the biggest strengths clients said about them is how involved their team is. They said the team feels like an extension of their own business rather than an outside agency.
That usually showed up through strong account management, regular updates, and a sense that the team really understands the brand they’re working on.
They also provide weekly summaries, clear explanations of performance, and transparency around what’s working and what isn’t.
They’re also great at paid advertising across Facebook, Instagram, TikTok, and even Google and Bing. Clients have witnessed improvements in visibility, audience growth, and conversions.
One long-term client even said their brand voice and social presence improved over several months. It seems like the team looks beyond short-term wins and thinks about how a brand shows up overall.
Their service offering is broad, covering SEO, digital PR, website development, and more.
However, they’re probably not the best fit for large enterprises looking for complex global campaigns or enterprise-level scaling at speed.
We worked with The Good Marketer for around two years, and they were fantastic!

We highly recommend them to anyone looking for a reliable and skilled media management partner.”

3. Visionary Marketing
Address: 5 City Rd
Phone: +44 191 607 6707
Business hours:
- Monday to Sunday: Open 24 hours
Visionary Marketing really excels in SEO and Google Ads. Instead of splitting accounts across junior staff or separate specialists, they rely on senior marketers who understand both channels.
This setup explains a lot about their strong return on ad spend (ROAS) figures, averaging around 8.9x. Divisions are being made with the full picture in mind.
Feedback also highlighted how tailored their approach is. Campaigns are built around real business goals instead of templates.
Clients said the team really understands what success actually looks like before launching anything.
We also noticed that they’re very selective. Visionary doesn’t try to onboard every business that comes their way. They’re willing to turn clients down if results aren’t realistically achievable.
Combined with monthly rolling retainers and no long-term lock-ins, this shows that they really prioritise outcomes over guaranteed recurring fees.
Just remember that their service leans heavily toward pay-per-click (PPC), SEO, and web design.
They’re not the strongest option for influencer campaigns or content-heavy marketing strategies.
Thanks to their efforts, my brand visibility has increased
“Great Digital Marketing Agency! I’ve had the pleasure of working with them, and their marketing strategies have truly transformed my business. They took the time to understand my goals and developed tailored campaigns that really drove results. Their team is professional, knowledgeable, and always ready to help. Thanks to their efforts, my brand visibility has increased, and I’ve seen significant growth in both leads and sales. Highly recommend their services to anyone looking to take their business to the next level!”

4. Passion Digital
Address: 4th Floor, Holborn Tower, 137-144 New Oxford St
Phone: +44 20 3432 1360
Business hours:
- Monday to Friday: 8 AM – 7 PM
- Saturday to Sunday: Closed
The biggest takeaway we had from Passion Digital is how they combine creativity and data in their approach, which actually supports actual growth.
Clients loved how involved the team was during their project. They often mentioned that they don’t feel passed around or dealt with by people who only manage tasks.
Everyone seems to think strategically, linking day-to-day channel work back to wider business goals. That setup makes collaboration smoother and helps campaigns stay aligned.
SEO and PPC were also mentioned a lot from feedback. There are strong signs of long-term success here. Some clients have worked with them for years and even brought them on across multiple companies.
Their wider digital marketing offering feels well-rounded too. Alongside SEO and paid search, they also cover paid social, content marketing, email marketing, and even Amazon Advertising.
We also heard how great they are at explaining complex digital concepts in plain English. This came through feedback from charities and less digitally mature organisations, particularly around Google Grants.
That said, there were a few mentions about initial contact being slower than expected.
They helped us significantly improve our Google rankings
“I have worked with the team at Passion Digital for the last couple of years. They have done a fantastic job for us, helping to significantly improve our Google rankings and providing support and advice on all things SEO. They are a lovely group of people too, and have been a great extension to our team. Would 100% recommend.”

5. Iconic Digital
Address: 7 Adam St
Phone: +44 20 7100 0726
Business hours:
- Monday to Friday: 9 AM – 5 PM
- Saturday to Sunday: Closed
After looking into Iconic Digital, it’s easy to see why they’re considered a strong player in digital marketing.
They’ve won 56 industry awards, including Golds for SEO and social at the National Industry Awards in 2014.
Their reputation is built on delivering real impact in SEO and paid advertising. Clients consistently see better Google rankings, more website traffic, and revenue growth.
For their approach, they use performance metrics, AI tools, and a creative “Ideas Factory” to make sure every campaign is precise and effective.
We’re impressed that they cover pretty much everything in digital marketing. They even do social media, content creation, email marketing, and more. Everything’s also tailored to the client, with free audits and competitor analyses.
They’ve also worked with big names like International Business Machine Corporation (IBM) and The Royal Collection. This led us to think they can handle both high-profile and complex projects.
One thing that really sets them apart, though, is their social responsibility. They donate a chunk of profits to charities in East Africa, Asia, and London.
The only downside is cost. Even satisfied clients admit their services are expensive. However, they also say it’s worth it.
An honest, knowledgeable and friendly team who have their clients’ best interests at heart
“I have been working with, Steven Pailthorpe, CEO of Iconic Digital now for over 3-months and it has been an eye-opener. Steve is extremely impressive, always bubbling over with ideas and energy. Creative as well as strategic, his zest for life, drive and ambition is a winning combination. This is exemplified throughout the team and everything Iconic Digital represent. An honest, knowledgeable and friendly team who have their clients’ best interests at heart. I cannot recommend Iconic Digital highly enough.”

Choosing the right partner was key for us and we are delighted with what the team of consultants at Iconic have done for us. Keep up the good work guys!”
