Top LinkedIn Ads Agencies for B2B (2026)

If you sell to other businesses, LinkedIn is the one platform where you can put an ad in front of a job title, a seniority level and a company size and be reasonably sure you have reached the right person. It is not cheap, and it is unforgiving of an account nobody looks at between month one and month six. So the question most founders ask is not whether LinkedIn works, it is who should be running it.

This is our list and we are on it, first. We would rather say that plainly than pretend a roundup written by an ads agency is neutral. The other four are UK agencies worth a conversation, chosen because they are small and lesser known rather than the names already sitting at the top of page one. Top here means notable and active, not ranked in order of quality, and every fact about them was read off their own website on 14 September 2026.

The short list

• Snowball Creations: for 7-figure SaaS and B2B brands that want LinkedIn and Google run together by one team.
• Winbox: a LinkedIn-only specialist built around a 90-day sprint with a specialist embedded in your team.
• Bespoke Digital Agency: a Lancashire B2B agency that builds the website as well as the campaigns.
• Reflect Digital: a Kent agency that puts behavioural research in front of the media buying.
• Flow20: a small London agency running LinkedIn beside Google Ads, paid social and SEO.

Snowball Creations

We are a paid ads agency, founded in 2017, based in London and on the south coast with the creative and marketing team in Cape Town. We run Google, Meta, LinkedIn, Microsoft, TikTok, Amazon and Wayfair for 7-figure SaaS, B2B and homeware e-commerce brands, and the work covers strategy, ad creative through Snowball Studios, campaign build, conversion tracking including offline conversions, and weekly, monthly and quarterly lever checks.

For B2B, LinkedIn is never a standalone line item here. It creates the demand that Google later converts, so the two are planned together and judged on qualified demos and paying users rather than raw form fills. The setup is a fraction of the job: the lever checks on a cadence are the product, and that is what you are paying for. There is more detail on our LinkedIn advertising service page and in our guide to running LinkedIn ads for B2B lead generation.

Why They’re a Good Choice

• Trusted by 100+ 7-figure+ brands, with clients averaging 5.1x ROAS (calculated over the previous four months of ad spend, including agency fees).
• For a UK and US property-management SaaS, paid ads became the second largest growth channel outside SEO by year three, from zero.
• Adrian Davies, co-founder of hubba: “the constant supply of high quality leads has left us with only one problem. Growing our sales team!”
• Fees from £1,749 per platform per month, on a three-month commitment then one month’s rolling notice, with a minimum ad spend of £2,500 a month per platform.

Winbox

Winbox is a LinkedIn specialist that sells one shape of engagement rather than an open-ended retainer. The pitch on its site is a 90-day sprint with an experienced LinkedIn specialist embedded in your team, after which the specialist can stay on at a reduced rate or you take the work in house, with no lock-in either way (read 14 September 2026).

The site lists what should be in place by the end of that sprint: campaign architecture covering a full funnel media plan, audience strategy, bidding strategy and testing framework; a creative and content system with a messaging guide, content calendar and templates; measurement and attribution covering channel return and which companies are engaging; and the AI tooling the agency built for its own campaigns. Creative can come from their in-house studio or from you.

Why They’re a Good Choice

• One platform only, which is unusual and means the account is not competing internally with a Google team.
• The sprint shape suits a company that wants to find out whether LinkedIn can work before committing to a year of retainer.
• Creative and media buying sit in the same place, which is where most LinkedIn accounts stall.
• A free audit of live campaigns is offered on the site, and the homepage carries a LinkedIn certified agency badge.

Bespoke Digital Agency

Bespoke is a B2B web and digital marketing agency with its head office at Strawberry Fields Digital Hub in Chorley, Lancashire, and further offices in Manchester and London. Its LinkedIn ads page describes a B2B specialism going back more than 20 years, and an in-house team building and managing LinkedIn campaigns at a range of ad spends, some for exposure and brand building, others for direct lead generation (read 14 September 2026).

LinkedIn sits inside a wider list on the same site: Google ads, Facebook ads, Microsoft ads, SEO and CRO, alongside website development and digital strategy workshops. The page carries HubSpot Diamond Partner and Google Partner badges and an Investors in People accreditation, and offers a free LinkedIn ads consultation by phone or email.

Why They’re a Good Choice

• Useful when the website is part of the problem, since the development team is in the same building.
• Based outside London, with a Lancashire head office, which is rare in this category.
• One team covering LinkedIn, Google, Microsoft and Facebook, so the channels are not argued about by three suppliers.
• The HubSpot Diamond Partner badge matters if your CRM is HubSpot and you want closed-loop reporting.

Reflect Digital

Reflect Digital is a performance agency based at Kestrel House in Maidstone, Kent, with people spread around the UK. Its LinkedIn page leads on behaviour rather than on media: a human behaviour team works alongside the paid social team, and campaigns start with a discovery process aimed at what motivates the audience to buy before anything is built (read 14 September 2026).

The LinkedIn work described covers sponsored content, text ads, dynamic ads and remarketing, with either an account-based marketing route or a more conventional lead generation route. Paid social sits next to SEO, paid media, digital PR, video production, CRO and customer experience, so LinkedIn can be one part of a bigger programme rather than the whole of it. The site states a rating of 4.95 out of 5 from 25 reviews on Facebook and Google (read 14 September 2026).

Why They’re a Good Choice

• The research-first approach suits a business whose problem is messaging rather than targeting.
• Named specialists on the page, so you can see who would be on the account.
• Video production in house, which matters as LinkedIn creative moves further towards video.
• A published review score, which is more than most agency sites give you (read 14 September 2026).

Flow20

Flow20 is a small London agency working from Ludgate Hill, offering LinkedIn advertising next to Google Ads, Facebook ads, social advertising, SEO and Google Ads training (read 14 September 2026). Its LinkedIn page is unusually explicit about measurement: qualified leads, conversion rates, cost per lead, cost per conversion and pipeline quality, with impressions and clicks treated as signals rather than as the score.

AI runs through the process the page describes, supporting audience research, competitor review, ad testing, campaign analysis and optimisation, with the final strategy shaped by the marketers rather than the tooling. The formats named include single image ads, document ads, video ads, carousel ads and Lead Gen Forms, and the targeting is described in terms of job titles, seniority, industries, company lists, matched audiences and website retargeting.

Why They’re a Good Choice

• Small enough that you will speak to the people doing the work.
• LinkedIn, Google and SEO under one roof, which helps when LinkedIn demand shows up as branded search.
• The stated measurement set is the right one for B2B, and it is on the page rather than in a pitch deck.
• Google Ads training is offered too, useful if you want to keep part of the work in house.

How to choose between them

Start with the mix rather than the platform. In most B2B SaaS accounts we run, about 75% of the budget sits on Google and about 25% on LinkedIn, because LinkedIn creates the demand that search later captures, and we set that split the way we set every other one, as explained in our post on ad budgets across different platforms. Brand campaigns are kept separate and small, roughly 5% of the budget, and brand conversions are never counted as growth.

Then ask what happens in week six. Anyone can build a campaign, and the build is the cheap part. What separates a good account from an expensive one is whether somebody is checking the levers weekly, monthly and quarterly, spotting creative fatigue and frequency before the cost per lead doubles, and telling you when the honest answer is that the audience is too small. Ask for that cadence in writing, and ask who is actually in the account, because on smaller retainers it is often not the person on the call.

Money is the last filter, not the first. Work out what a qualified demo is worth to you, then read our post on what a sensible LinkedIn budget looks like and the comparison of an agency, a freelancer and an in-house hire.

What a good first quarter looks like

Two stages, in that order. Stage one is finding the fit: a wide range of A/B tests across targeting, messaging and creative, to find which roads lead to the highest uptick. Stage two is scaling the spend, protecting the winners with about 80% of the budget and putting the other 20% into new tests, the same shape we use in our SaaS campaign structure. Anyone who skips stage one and spends month one scaling is guessing with your money.

Expect the early numbers to look worse than Google’s, because they will. LinkedIn’s cost per lead sits above search in nearly every account we have run, and the case for it is the quality of the company behind the lead, not the price of it. That is why the growth has to be paced: we never more than double an account’s spend inside a single month, and we scale on impression share and volume rather than on one good week. If your lead gen forms fill up with job seekers and students, the fix is the offer and the targeting, not more budget.

Where we would start

Pick two from this list, ours included, and give each the same brief: here is the product, here is the person who buys it, here is what a qualified demo is worth, tell us what you would do in the first 90 days and who would do it. The answers differ far more than the websites do, and the agency that asks about your sales process before it talks about ad formats is usually the one to take seriously. If you are not sure you need anyone at all, we wrote about when hiring a paid ads agency is the wrong move and we meant it.

If you want a second opinion on an account you are already running, get in touch and we will audit it for free. Tell us what you are spending, what it is returning and what a customer is worth, and we will tell you what we would change, whether or not you end up working with us. For software businesses, there is more on our paid ads for SaaS page.
