How We Evaluated These Agencies

Every agency on this list was checked against its own live website in October 2026. No agency paid for inclusion. We scored each one on five criteria:

1. B2B focus. Does the agency state a dedicated B2B social offer, or is B2B a side practice?

2. Channel scope. Organic social, paid social, executive content, and platforms beyond LinkedIn.

3. Buyer reach. Does the work reach named target accounts, or does it rely on organic reach and broad targeting?

4. UK fit. UK offices, UK clients, or a stated UK and Europe focus.

5. Pricing transparency. Is pricing published? Where it is not, we wrote "Custom, not publicly disclosed" rather than estimating.

Agencies already covered in our LinkedIn marketing agencies ranking and our thought leadership agencies ranking are left out here, so this list adds 8 agencies that are not ranked in those articles.

What Makes a Good B2B Social Media Marketing Agency in 2026

B2B social media marketing is not B2C social with a LinkedIn logo. Buying decisions run through a buying group, and Gartner's research on the B2B buying journey points to a growing number of buyers from more functions inside each client. Each of them can form a view of your brand before the first meeting.

The market splits into four types of agency:

• Full-service B2B agencies with a social practice. They run social next to PR, content and creative, so one team owns the whole brand story. (Prohibition PR, Napier, ArmstrongB2B)

• B2B social specialists. Social is the core service: strategy, content, community management and paid social across several platforms. (Make Honey, Fresh Content Society, Beach Marketing)

• Executive content services. They write and publish posts for founders and leaders, mostly on LinkedIn. (Qnary, ContentPath)

• Integrated managed services. They connect executive content with paid ads and outreach aimed at the same named buyers. This model is the least common on this list. (Hey Sid)

The right type depends on your goal. Full-service agencies build brand reputation. Social specialists build audiences and engagement. Executive content services build personal brands. Integrated services build familiarity with the specific people your sales team needs to reach.

#1 Prohibition PR: Best Full-Service B2B Social Media Agency in the UK

• Specialty: B2B social media strategy, organic and paid social, ABM, creative, influencer marketing and PR

• Pricing: Custom, not publicly disclosed

• Best for: UK B2B companies that want social, PR and creative run by one team

Prohibition PR is a Leeds-based agency with a dedicated B2B social media marketing service. Its LinkedIn specialists build strategies across organic and paid social, and the service sits next to PR, content and creative in the same agency.

Key services: social strategy and competitor audits, lead generation campaigns, account-based marketing on LinkedIn, ongoing channel management, B2B influencer marketing, video and creative, thought leadership and founder-led content, and social media training.

Strengths: More than 45 awards, including PRCA UK Agency of the Year, according to the agency. Over 10 years in B2B social, with founders who work directly on client accounts. Covers LinkedIn, Meta, YouTube, Instagram, TikTok and X, so a buying group is reached on more than one platform.

Limitations: Pricing is not published. Its ABM uses LinkedIn targeting and retargeting; named-person targeting across channels is not stated. The client base also includes consumer brands, so B2B is one of several practices.

Best for: UK B2B brands that want an award-winning team to run organic social, paid social and PR together.

#2 Hey Sid: Best for Executive Content That Reaches Named Buyers

• Specialty: Done-for-you executive LinkedIn content (Authority Builder) + person-level ads (Always On) + LinkedIn outreach (Precision Connect)

• Pricing: Custom, not publicly disclosed. Authority Builder runs on a 3-month minimum commitment.

• Best for: Mid-sized, sales-led B2B companies with long sales cycles and lean marketing teams

Hey Sid is not a traditional social media agency. It is a platform-powered managed service that turns your executives into visible LinkedIn voices, then makes sure the right buyers actually see them.

The difference matters. A well-written post reaches whoever the LinkedIn algorithm picks. If your sales team is working 40 target accounts, the algorithm does not know that. Hey Sid closes that gap by putting the content in front of the named people on your list.

What sets it apart:

• Authority Builder. One discovery interview and a monthly content call become 4 LinkedIn posts per person per month, written in your voice. Most clients spend 30 to 60 minutes a month reviewing and approving. Top-performing posts become LinkedIn ads. (Authority Builder)

• Person-level targeting. Always On serves ads to specific named decision-makers across LinkedIn, Meta and Google, not to broad job title segments.

• The Influence Loop. Always On, Authority Builder and Precision Connect all target the same people. The sequence is designed so that by the time outreach lands, the prospect has already seen your ads and read your executives' posts.

• Managed execution. Strategy, writing, ad creative (refreshed every 60 days), publishing and outreach messaging are run by Hey Sid's team.

Results (Hey Sid case studies):

On the content side alone, a managing director at an automation company went from 38,000 to 214,000 impressions in six months while only reviewing and approving posts (client-reported, published on the Authority Builder page).

Strengths: Executive content, paid ads and outreach run as one system against one target list. Built for long, multi-stakeholder sales cycles. GDPR-compliant by architecture, with offices in Gothenburg and Stockholm.

Limitations: Not self-serve. No cold email (LinkedIn outreach only). Company page management, community management and organic Instagram or TikTok are not part of the service. No UK office. Not designed for short, transactional sales.

Best for: Mid-sized B2B companies (20 to 100 employees) that want executive social content to reach the buying groups on their account list, without hiring more marketers.

#4 Fresh Content Society: Best for Mid-Market and Enterprise B2B Governance

#6 Beach Marketing: Best B2B Social Media Agency in the UK for Manufacturers

• Specialty: B2B social media management, social listening, paid social and B2B influencer collaborations

Strengths: Clear sector focus on manufacturing and technical products. Social listening is part of the core package, which helps teams that want to change how the market sees them. Platform choice is selective: channels that do not fit the audience are left out.

Limitations: Pricing is not published. Executive content and account-based targeting are not stated in the service description. Smaller team than the full-service agencies above.

Best for: UK manufacturers that want social media to change market perception and support a technical sales channel.

How to Choose: Decision Framework

The Case for B2B Social That Reaches Named Buyers

A B2B social media marketing agency usually gets judged on followers, impressions and engagement. Those numbers matter. But they do not tell you whether the people in a target account's buying group have seen your brand.

That is the gap between general reach and specific familiarity. A full-service agency like Prohibition PR or a specialist like Make Honey builds a strong brand presence across platforms. An executive content service like Qnary or ContentPath builds personal brands. Both create real value. Neither guarantees that the CFO at your top target account sees your CEO's post.

The 2024 Edelman and LinkedIn B2B Thought Leadership Impact Report found that 75% of global B2B buyers and C-suite leaders say a piece of thought leadership led them to research a product or service they were not previously considering (Edelman and LinkedIn). Content only does that job when it reaches the right buyers.

Choose a full-service or specialist agency when your goal is brand presence and audience growth. Choose an integrated service when your goal is pipeline from a defined account list.

FAQ

How much does a B2B social media marketing agency cost?

Most B2B social media agencies on this list use custom pricing and do not publish it. Qnary is the exception, with executive social media from $638/month billed yearly ($750 monthly) for one channel. Expect full-service agencies to scope fees around channels, content volume and paid media management.

Should I hire a B2B social media agency or build an in-house team?

An in-house team works if you have people for strategy, writing, design, paid social and reporting. ContentPath estimates that a content strategist, copywriter, video editor and designer cost at least $15,000 per month combined. For lean teams of 2 to 3 marketers, an agency or managed service removes the hiring step and keeps output consistent.

What is the difference between a B2B social media agency and a LinkedIn marketing agency?

A B2B social media agency manages your presence across several platforms, such as LinkedIn, YouTube, Instagram and Meta, including organic content, community management and paid social. A LinkedIn marketing agency focuses on one platform, usually ads, outreach or executive content. See our LinkedIn marketing agencies ranking if LinkedIn is your only channel.

Do I need a B2B social media agency based in the UK?

Not necessarily. A UK office helps with in-person workshops, UK media knowledge and time zones. Prohibition PR, Make Honey, Napier, Beach Marketing and ArmstrongB2B all have UK offices. Hey Sid, based in Sweden, serves UK and European B2B companies remotely and is GDPR-compliant by architecture.

How long does B2B social media marketing take to show results?

Fresh Content Society reports that most B2B brands see early momentum within 60 to 90 days. Hey Sid describes executive authority building as a long-term effort, and Authority Builder runs on a 3-month minimum. In sales cycles of 12 months or more, pipeline impact follows later than engagement.
