B2B marketing agencies exist because most in-house teams hit the same ceiling: too many channels to run properly, too little time to build a repeatable pipeline engine, and not enough specialist depth to cover everything from positioning to paid media to conversion. If you’re trying to grow in a competitive category, “doing a bit of marketing” isn’t the job — building demand and supporting revenue is.
This guide is for UK-based B2B founders, marketing leads, and growth teams who are in one of three situations: you’re hiring your first external partner, you’re switching agencies after slow delivery or unclear ROI, or you’re trying to make marketing carry more weight in the funnel (more qualified leads, more sales-ready opportunities, better conversion rates). It’s also relevant if you’re selling B2B SaaS, professional services, or a high-consideration product where trust, proof, and sales alignment matter as much as traffic.
We put this list together because “best B2B marketing agencies” searches usually return the same problem: long directories that tell you nothing about fit. You’re not here to read a stack of vague descriptions — you’re here to shortlist 2–3 agencies and go into those first calls with a clear view of what each one is likely to be good at, what to watch out for, and what success should look like.
Each agency included is assessed on signals a buyer can sanity-check: search visibility and brand presence, clarity of offer, public proof (case studies, client feedback, or credible examples of B2B delivery), and whether they appear to specialise in the kind of work B2B companies actually need (demand gen, ABM, brand-to-demand, HubSpot/RevOps, PR/AR, partner marketing). The aim is simple: help you avoid the wrong fit, reduce your research time, and choose a partner based on how they work — not how well they write about themselves.
“Most ‘top agency’ lists are basically directories. This one’s written to help you pick: what each agency is actually good at, who they suit, and what to ask on the first call.”
— Chris Ramos, Munro Agency
How we built this shortlist
This list is designed to help you narrow to a small set of agencies quickly, then qualify them properly on the first call. We focused on signals that matter to buyers: proof of delivery, clarity of specialism, and whether the agency’s model fits how you actually need content to work (SEO, pipeline, production, comms, video).
-
Baseline eligibility: We only considered agencies that clearly position content marketing as a core service and show evidence of active delivery (case studies, named work, or credible third-party presence).
-
Operating model: We assessed whether they can run content end-to-end (strategy → production → distribution → reporting/iteration), not just create assets.
-
Best-fit clarity: We prioritised agencies with a recognisable lane (e.g., SEO-led growth, B2B demand gen, ecommerce, video-first, integrated digital), so you can self-select fast.
-
Credibility checks: We looked for proof you can verify quickly — examples of work, reputation signals, and consistency across public profiles (not just marketing claims).
-
Buyer-first write-up: Each entry is structured to support decisions: who they suit, what they typically deliver, how they’re different, and what to ask to confirm fit before you commit.
1. Munro Agency


The Munro Agency is a Glasgow-based digital marketing firm that positions content as part of a wider growth system — combining content + SEO + PPC + website + lead generation rather than treating content as a standalone “blog production” service. They lean heavily into measurable outcomes and automation-led execution.
Office Location: Glasgow, Scotland, UK
Year Founded: 2015
Team Size: 2 – 10 employees
Key Services: Marketing Automation, B2B Lead Generation, Website Design and Development, SEO, PPC Advertising, Social Media Marketing
Industries Served: Consulting, Sustainability, Events, Hospitality, Technology
Case Studies: View all case studies
Best for
A strong shortlist option if you want content that supports lead generation — especially when success depends on the full path from content → capture → nurture → conversion, not just publishing output.
What they typically deliver
-
Content planning that supports commercial goals (not just awareness topics)
-
SEO-led content creation designed around ranking intent and conversion paths
-
Landing page and on-site alignment so content has somewhere useful to send traffic
-
Marketing automation and nurture sequences that follow up on content-driven leads
-
Reporting and iteration that ties content performance back to enquiries/leads (where tracking is set up properly)
Structural difference
Their edge is the operating model: content is built to work inside a broader acquisition and conversion setup. If your bottleneck is “we get attention but it doesn’t turn into leads,” that joined-up approach is usually what’s missing.
Commercial context
Best suited to ongoing partnerships where you want one team to carry multiple parts of the machine (content + SEO + automation, sometimes paid/web). If you’re hiring them mainly for content production, be clear on what’s included versus what sits under SEO/paid/automation scope.
Ask them this
-
“What does a typical month include — strategy, briefs, writing, optimisation, publishing, reporting — and who owns each part?”
-
“How do you decide what to publish: keyword intent, ICP pain points, sales objections, competitor gaps — and what’s the process?”
-
“How do you connect content to leads: landing pages, forms, attribution, nurture, sales handover — and what tooling do you use?”
Who should shortlist (and who shouldn’t)
Shortlist The Munro Agency if:
-
You want content tied to lead generation and measurable outcomes
-
You need content integrated with SEO and conversion mechanics (not managed in a silo)
-
You’d benefit from marketing automation/nurture alongside content
Probably not the best fit if:
-
You want a pure editorial studio focused on longform storytelling with minimal performance overlay
-
You only need occasional one-off content pieces with no ongoing optimisation or funnel ownership

2. Divigate


Digivate is a London-based digital marketing agency that sits in the “performance + conversion” camp. Content is usually planned and delivered as part of a wider programme (SEO, PPC, CRO, UX, analytics), rather than as a standalone publishing service — which makes them a strong option when content has to drive measurable outcomes and improve what happens after the click.
Office Location: London, England, UK
Year Founded: 1998
Team Size: 11-50 employees
Key Services: PPC, SEO, Social Media, Content Marketing, Email Marketing, Web Development
Industries Served: Information Technology, Telecommunications, Transportation & Logistics, Advertising & Marketing
Case Studies: View all case studies
Best for
Digivate is a strong shortlist option if you want content tied to performance — especially when results depend on the full system (search visibility + paid distribution + landing pages + conversion improvements), not just creating more assets.
3. Soap Media


Soap Media is a UK full-service digital agency with offices in Preston and Manchester, positioned around “customer journey” delivery. In practice, that means content is usually planned and executed alongside the rest of the performance stack (UX/CRO, web, paid, SEO, CRM/email), rather than treated as a standalone publishing function.
Office Location: Manchester and Preston, UK
Year Founded: 2005
Team Size: 11-50 employees
Key Services: Digital Strategy, Website Development, Email Marketing, Social Media Marketing, Video Marketing, Paid Media Campaigns, Digital PR Campaigns
Industries Served: Finance, Non-Profit Organisations, Retail Luxury Goods
Case Studies: View all case studies
Best for
Soap Media is a strong shortlist option if you want content integrated into a wider customer journey, especially when performance depends on the full path from click → landing page → conversion, not just the content asset itself.
4. Brafton


Brafton is a global content marketing agency with a UK base in London. They’re built for scale — meaning content is often delivered as an ongoing production system (writing, video, design, SEO, social, email), with process, capacity, and consistent turnaround as a key part of the pitch.
Office Location: London, England, UK
Year Founded: 2008
Team Size: 201-500 employees
Key Services: Content Writing, Video Marketing, Graphic Design, SEO Marketing, Social Media Management, Email Marketing, Paid Search Marketing
Industries Served: Technology, Telecommunications, Manufacturing
Case Studies: View all case studies
Best for
Brafton is a strong shortlist option if you need high-volume, multi-format content delivered consistently — especially when your internal team has direction (ICP, offers, positioning) but not the bandwidth to execute at the pace you want.
5. We Are Sunday


We Are Sunday (often branded as Sunday) is a London-based content marketing and publishing agency with an editorial-led model. They’re set up like a modern publisher: strategists, editors, designers, and channel specialists building owned content programmes, campaigns, and community-driven work — not just producing ad-hoc blog posts.
Office Location: London, England, UK
Year Founded: 51-200 employees
Team Size: 2005
Key Services: Content Strategy, Content Creation, Social and Community Management, Commercial Services
Industries Served: Membership Organisations, Travel, Retail, Financial Services, B2B, Food and Drink, Health and Beauty, Property, Charity, Luxury Brands
Case Studies: View all case studies
Best for
Sunday is a strong shortlist option if you want editorial-quality content that behaves like a publishing programme — especially for brands that need consistent stories, formats, and audience engagement across owned channels (and not just SEO articles).
What they typically deliver
-
Editorial-led content strategy (themes, formats, content pillars, channel plan)
-
Multi-format content production (series, campaigns, social-first assets, publishing-style outputs)
-
Community and channel support so content doesn’t rely on “post and hope”
-
Content built for specific audiences: members, customers, stakeholders, or interest-led communities
Structural difference
Sunday’s advantage is the publisher-style operating model. They’re less about “we’ll write X posts per month” and more about building a content system with repeatable formats, consistent quality control, and channel thinking — the stuff that makes content feel like it belongs.
Commercial context
Best suited to organisations that value editorial craft and long-term audience building. If your primary KPI is pipeline, make sure the engagement includes:
-
conversion paths (where content sends people),
-
distribution ownership,
-
and a clear measurement plan (otherwise great content can look “soft” on ROI).
Ask them this
-
“Are you building an owned-media programme (formats + series + channels), or delivering individual assets — and what does success look like in each model?”
-
“Who owns distribution and community management day-to-day, and what cadence do you recommend?”
-
“How do you measure performance beyond views — engagement quality, membership impact, enquiries, and assisted conversion?”
Who should shortlist (and who shouldn’t)
Shortlist We Are Sunday if:
-
You want a content partner that can run publishing-grade content end-to-end
-
Your brand needs consistent storytelling across channels (not just search content)
-
You care about audience engagement, membership, or community outcomes
Probably not the best fit if:
-
You want a pure SEO growth partner focused mainly on rankings and organic acquisition
-
You mainly need high-volume low-cost production with light editorial input

6. Digital Litmus


Digital Litmus is a London-based B2B growth agency where content is usually delivered as part of a wider demand engine (strategy, SEO, paid, HubSpot, and campaign execution), not as a standalone “content studio”. If you’re trying to get content to carry more weight in the funnel — pipeline, qualified leads, sales enablement — this is the kind of operating model that tends to work.
Office Location: London, England, UK
Year Founded: 2016
Team Size: 11-50 employees
Key Services: Marketing Strategy, Content & SEO, Paid Campaigns, Website Development, HubSpot Setup & Onboarding, HubSpot Support & Training
Industries Served: Technology, Industrial, Professional Services
Case Studies: View all case studies
Best for
Digital Litmus is a strong shortlist option if you want content built to generate and progress demand — especially when the gap isn’t “we need more posts”, it’s “we need content that creates MQLs, supports sales conversations, and turns into pipeline”.
7. Synima


Synima is a video-first content agency with studios in London plus international locations (including New York, Los Angeles, Amsterdam). Their offer is built around film, animation, and high-production brand content — the kind of work you use when content needs to carry the message, not just support it in the background.
Office Location: London, England, UK
Year Founded: 2000
Team Size: 51-250 employees
Key Services: Video Production, Animation, Digital Learning Solutions, AI Integration, Social Media Content Creation
Industries Served: Healthcare, Finance, IT & Technology, Government, Non-Profit Organisations
Case Studies: View all case studies
Best for
Synima is a strong shortlist option if you need video to do the heavy lifting — launches, brand campaigns, product explainers, high-stakes internal comms, or enterprise storytelling where production quality and creative execution matter.
What they typically deliver
-
High-production video assets (brand films, commercial-style pieces, campaign videos)
-
Animation and motion-led storytelling for complex topics (useful in finance/health/tech)
-
Video series work that supports longer-term campaigns and channel consistency
-
End-to-end production (concept → shoot → post → final delivery across formats)
Structural difference
Synima’s edge is production depth and global delivery. They’re built to handle multi-location shoots, enterprise stakeholders, and content that needs to look and feel premium — which is a different operating model from SEO-led or editorial-led content agencies.
Commercial context
Best suited to projects or retainers where video is a core channel. If you’re comparing them to “content marketing agencies,” be clear internally that you’re buying creative production capability (and the planning that supports it), not a blog/SEO content engine.
Ask them this
-
“What does your process look like from brief to creative development to production — and how do you manage stakeholder approvals?”
-
“How do you plan outputs for distribution (cutdowns, aspect ratios, paid/social variants), and what’s included by default?”
-
“Where do you draw the line between strategy and production — do you help shape the messaging and narrative, or do you mainly execute the brief?”
Who should shortlist (and who shouldn’t)
Shortlist Synima if:
-
Video needs to be a primary driver of your content strategy
-
You’re producing work for enterprise audiences or high-visibility campaigns
-
You need a partner who can manage complex production and deliver consistently across formats
Probably not the best fit if:
-
Your main goal is SEO-led growth (rankings, content clusters, organic acquisition)
-
You want high-volume written content production at low cost
-
You need a comms/PR-led partner rather than a production-led one

8. Tiga


Tiga Creative Marketing is a Kent-based B2B agency that blends content with broader campaign delivery — brand, web, digital, and lead-gen support. In practice, that means content is usually created to support a clear commercial job (awareness in a niche market, sales enablement, demand capture), rather than published as a standalone editorial programme.
Office Location: Meopham Green, Kent, UK
Year Founded: 1991
Team Size: 11–50 employees
Key Services: B2B Marketing, Branding, Content Marketing, Digital PR, Digital Strategy, Email Marketing, PPC, SEO, Social Media Marketing, Web Development
Industries Served: Automotive, Education, IT & Technology, Media & Entertainment, Real Estate
Case Studies: View all case studies
Best for
Tiga is a strong shortlist option if you need B2B content that supports campaigns and sales enablement, especially where content needs to sit alongside web, SEO, and paid activity — not just “more posts”.
What they typically deliver
-
Campaign-led content built around a defined audience and commercial objective (not generic publishing)
-
B2B content and creative assets that can be used across channels (site, email, paid, sales materials)
-
Web and digital execution to support the content (so content has somewhere effective to convert)
-
Ongoing support across digital channels when content needs distribution (SEO/PPC/email)
Structural difference
Tiga’s strength is integrated B2B delivery: they’re set up to combine content with brand, web, and channel execution so the content is part of a campaign system — not a silo.
Commercial context
Best suited to teams that want a partner who can deliver content plus the supporting digital pieces (web, distribution, optimisation). If you only want content production, make sure you define whether you’re buying strategy + campaign planning, or just asset delivery — and who owns measurement and iteration.
Ask them this
-
“Are you approaching content as a publishing programme, or as campaign support — and what does a typical month look like in each?”
-
“What’s included end-to-end: strategy, briefs, writing/design, landing pages, distribution (SEO/PPC/email), and reporting?”
-
“What do you usually build for B2B teams: sales enablement libraries, lead magnets, landing pages, nurture sequences — and how do you measure success?”
Who should shortlist (and who shouldn’t)
Shortlist Tiga if:
-
You need B2B content that supports campaigns, sales enablement, and conversion paths
-
You want content integrated with web and channel execution (SEO/PPC/email)
-
You prefer one partner to coordinate multiple moving parts
Probably not the best fit if:
-
You want a pure-play editorial studio focused mainly on longform storytelling and owned-media publishing
-
You’re looking for an SEO-only specialist focused narrowly on organic rankings and technical SEO

9. Salience


Salience is a Chester-based search marketing agency where content is typically delivered as part of a wider organic growth and performance programme — usually alongside SEO, PPC, and digital PR. They’re not positioned as an editorial studio; they’re a good option when you want content to earn its place through rankings, demand capture, and measurable commercial outcomes.
Office Location: Chester, England, UK
Year Founded: 2009
Team Size: 11-50 employees
Key Services: SEO, PPC, Content Marketing, Digital PR, Social Media, Digital Strategy, eCommerce, Online Advertising
Industries Served: Retail, Finance, Charity, eCommerce, Lead Generation
Case Studies: View all case studies
Best for
Salience is a strong shortlist option if you’re hiring content to support search visibility and revenue outcomes — especially for ecommerce or lead gen brands where content needs to rank, convert, and be supported by technical SEO and authority-building.
What they typically deliver
-
Search-led content strategy (intent mapping, topic coverage, prioritisation)
-
Content production designed to support SEO performance (not just publishing cadence)
-
Digital PR / outreach support where authority is the limiting factor
-
PPC support where content needs distribution or paid testing
-
Ongoing iteration based on performance (refreshing, consolidating, expanding what works)
Structural difference
Their advantage is being built around search as a system, not content as an output. If your main problem is “we’ve published plenty and it hasn’t moved the needle,” a search-led operating model is often the missing piece.
Commercial context
Best suited to ongoing partnerships where SEO + content + (often) PR are working together. If you’re approaching them primarily for content, make sure you’re aligned on what they consider “content marketing” — and whether technical SEO, digital PR, and CRO are part of the plan or separate scopes.
Ask them this
-
“How do you choose what to publish first — revenue opportunity, keyword intent, category strategy, or competitor gaps?”
-
“What happens after content goes live: updates, consolidation, internal linking, CRO improvements — and how often do you iterate?”
-
“When rankings don’t move, how do you decide whether the fix is content quality, technical SEO, or authority (PR/links)?”
Who should shortlist (and who shouldn’t)
Shortlist Salience if:
-
You want content tied to SEO performance and commercial outcomes
-
You need an agency that can support content with technical SEO and digital PR
-
You’re in ecommerce, finance, charity, or lead gen where search demand is a major lever
Probably not the best fit if:
-
You want a publisher-style editorial partner focused on storytelling and owned-media programming
-
You mainly need low-cost, high-volume content production without deep SEO strategy and iteration

10. Re:signal


Re:signal is a UK-founded eCommerce SEO and content marketing agency that’s built around organic revenue growth — not general “content marketing” output. They’re structured like a search consultancy: strategy, technical SEO, content, and digital PR working together to drive commercial outcomes (especially for retail and DTC brands).
Office Location: London, England, UK
Year Founded: 2012
Team Size: 11-50 employees
Key Services: Search Engine Optimisation, Digital PR, Content Production, Content Syndication, Search Insights
Industries Served: eCommerce, Fashion Retail, Fintech, Health & Wellness, Sports & Fitness

Best for
Re:signal is a strong shortlist option if you want content as part of an SEO-led growth system — particularly when the goal is organic revenue and you need the supporting pieces (technical + authority + category strategy), not just “more content”.
11. CopyHouse


CopyHouse is an Edinburgh-based content marketing agency that specialises in technology and complex industries. Their positioning is straightforward: take technical, regulated, or high-context products and turn them into content that’s clear, credible, and usable across the funnel (SEO, thought leadership, sales enablement, and social).
Office Location: Edinburgh, Scotland, UK
Year Founded: 2018
Team Size: 11–50 employees
Key Services: Content Marketing Strategy and Consultancy, Specialist Content Writing, Social Media Marketing, Content Design, PR Services
Industries Served: Fintech, Blockchain, Artificial Intelligence, Software Development
Case Studies: View all case studies
Best for
CopyHouse is a strong shortlist option if you need content for technical or complex products — especially when you’ve struggled to get agencies to “get it” without heavy internal hand-holding.
What they typically deliver
-
Long-form content and thought leadership that doesn’t read like generic marketing copy
-
Stakeholder/SME-led writing (interviews turned into publishable assets)
-
SEO content that’s still technically accurate (common failure point in specialist sectors)
-
Sales enablement-style assets (case studies, explainers, pillar pages) that sales teams can actually use
-
Multi-format support when you need the same ideas repurposed for social, email, and campaigns
Structural difference
Their advantage is subject-matter handling. They’re set up to work in spaces where accuracy and credibility matter (and where fluff gets punished by buyers). If your internal experts are busy, this matters because the agency has to do real research and ask the right questions.
Commercial context
Best suited to retainers or ongoing programmes where your content needs consistency and quality control. If you’re comparing them to a generalist content agency, ask how they balance depth vs. throughput — and what their process looks like when SME access is limited.
Ask them this
-
“How do you get up to speed on a complex product — what’s your SME interview process and how much time do you need from our team?”
-
“What does a typical month include: strategy, briefs, writing, edits, SEO optimisation, publishing, reporting — and who owns each part?”
-
“How do you keep technical accuracy high without turning the content into jargon — and what does your review workflow look like?”
Who should shortlist (and who shouldn’t)
Shortlist CopyHouse if:
-
You’re in tech/fintech/regulated or complex categories and need content that holds up under scrutiny
-
You want a partner who can produce credible long-form assets and thought leadership
-
You need an agency that can translate technical detail into buyer-friendly language
Probably not the best fit if:
-
You want a high-volume, low-cost content factory with minimal SME involvement
-
Your priority is PR-first “big splash” campaigns rather than ongoing specialist content delivery

12. Folk


Folk is a Cardiff-based communications agency that sits closer to campaigns + press office + content than to “SEO blog production”. Their work typically blends strategy, creative campaigns, news-led content (including reactive work), and influencer/community activity — useful when content needs to earn attention through ideas, narratives, and distribution, not just publishing volume.
Office Location: Cardiff, Wales, UK
Year Founded: 2022
Team Size: 11-50 employees
Key Services: Insights, Strategy, Creative Campaigns, Newsjacking, Content Generation, Influencer Relations
Industries Served: Healthcare, Non-Profit Organisations, Hospitality

Final shortlist advice and next steps
If you’re choosing between agencies on this list, don’t start with “who looks best”. Start with what you need content to do. SEO-led growth, B2B pipeline, ecommerce revenue, video-first storytelling, and comms-led campaigns are different disciplines with different delivery models. The quickest way to avoid a bad hire is to pick one primary outcome, map it to the right type of agency, then use the “Ask them this” questions above to pressure-test fit before you commit.
If you want a partner that treats content as part of a measurable growth system — connecting strategy, SEO, conversion paths, and follow-up so content doesn’t die on the page — contact Munro Agency. We’ll tell you quickly whether we’re the right fit and, if not, what type of agency model you should be looking for instead.
