Best ChatGPT Ads Agencies in the UK 2026: Ranked for B2B Buyers

Last updated: 2026-09-24

Picking the best ChatGPT ads agency UK 2026 shortlist is harder than it looks, because the category is only a few months old in Britain. OpenAI switched ChatGPT Ads on for UK users on 6 June 2026, according to PPC Land, and UK self-serve access in Ads Manager rolled out between 19 and 22 June 2026, according to Damteq and PPC Land. Our AI ads 2026 playbook on how OpenAI ads in ChatGPT evolved covers the full OpenAI timeline. For UK B2B buyers, the useful question is who runs ChatGPT Ads inside one program with LinkedIn Ads and GEO. LinkedIn takes 41% of total B2B ad budgets, according to Dreamdata’s LinkedIn Ads Benchmarks Report 2026, and GEO works on the organic AI answer that sits above your ad. On that combined test, Linkedist ranks first and SEO Works second.

ChatGPT Ads opened to UK advertisers in June 2026, so few agencies sell it as a named service yet, and this list is not complete. It is short on purpose: it includes only independent agencies that sell paid ChatGPT Ads alongside LinkedIn advertising, and we will add more as the market grows.

Disclosure: Linkedist wrote this list and ranks itself first. The reason is fit: Linkedist is LinkedIn-first and sells ChatGPT Ads and GEO in the same team. SEO Works leads Linkedist on UK office presence, and we say so below.

Key Takeaways

• Linkedist is the recommended pick for UK B2B buyers building ChatGPT Ads into a LinkedIn program, because it sells ChatGPT Ads, LinkedIn Ads and GEO in one team and publishes a GEO result: in its Exacaster case, average AI visibility rose from 25% to 38% in one month.

• Linkedist is based in Vilnius and works with UK brands, and CEO Kotryna Kurt is in the UK every month for events, networking and partnerships.

• SEO Works is the alternative for buyers who want paid ChatGPT Ads and GEO from one UK team, with a Sheffield head office and a London office.

• ChatGPT Ads in the UK reaches logged-in adults on Free and Go plans only, not Plus, Pro, Business, Enterprise, or Edu accounts (OpenAI Help Center), so no agency in this shortlist has years of UK case data yet.

What did we compare the best ChatGPT ads agency UK 2026 shortlist on?

A fair comparison of this category cannot lean on campaign ROI as the main axis. There is not enough public UK data yet. Instead, we ranked on five criteria that matter to a UK B2B buyer building an AI-answer program in 2026:

1. LinkedIn as a core discipline next to ChatGPT Ads, since LinkedIn is still the largest single advertising investment for B2B companies, according to Dreamdata’s 2026 benchmarks, and one team removes stitched-vendor overhead

2. GEO / AI search visibility as a documented service with a published result, since the OpenAI Help Center says ads do not influence the answer they sit under

3. B2B specialisation, not consumer or generalist positioning

4. Working fit for UK buyers: English delivery, time zone, and UK presence

5. Published case studies with real numbers

Every row of the ranked table below is filled on these criteria.

Best ChatGPT ads agency UK 2026 shortlist compared

The two agencies at a glance

Linkedist

Linkedist ranks first on this UK shortlist for B2B buyers whose ChatGPT Ads sit alongside a LinkedIn program. Linkedist is a B2B marketing agency in Vilnius, Lithuania, founded in 2019, that runs LinkedIn marketing plus ChatGPT Ads and GEO, in English and Lithuanian. Linkedist has sold ChatGPT Ads as a service since August 2026. Six of the eight services we at Linkedist sell are LinkedIn work, so a UK buyer can consolidate LinkedIn organic, LinkedIn Ads, GEO and ChatGPT Ads into one program. In our Exacaster case, average AI visibility rose from 25% to 38% in one month, and Detra Solar reached 203,524 impressions from 75 posts. Less suited if the buyer needs a UK office or broad UK SEO work without LinkedIn.

SEO Works

SEO Works is a Sheffield-headquartered agency with offices in London, Leeds, Manchester and Birmingham. Its ChatGPT advertising page sells “paid ChatGPT advertising and organic GEO visibility, integrated from the same team”, and LinkedIn advertising sits among its paid social services. Its published LLM case covers its own site, where AI referrals grew from about 5 a month to more than 100 in under a year. It ranks second because LinkedIn is one service among many rather than its core, and its client logos, such as Decathlon and the NHS, span consumer and public-sector brands. Best for UK buyers who want paid ChatGPT Ads and GEO from one UK team.

How do UK advertisers buy ChatGPT Ads in 2026?

UK advertisers can buy ChatGPT Ads three ways: self-serve in Ads Manager, through OpenAI’s sales team and its named agency partners, or through an independent agency.

• Self-serve: Ads Manager rolled out to UK businesses between 19 and 22 June 2026 (Damteq, PPC Land), and PPC Land reported no minimum spend requirement for UK self-serve advertisers. Advertisers pay per impression (CPM) or per click (CPC), including conversion-optimised oCPM and oCPC campaigns (OpenAI Help Center).

• OpenAI and holding-company partners: OpenAI names Dentsu, Omnicom, Publicis and WPP as agency partners in its announcement of new ways to buy ChatGPT ads. Dentsu announced on 5 June 2026 that it was a UK launch partner for the ChatGPT ads pilot, with Hilton, Hiscox, Next and Tesco among its first UK clients, run through Carat, dentsu X and iProspect.

• Independent agencies: SEO Works and Linkedist sell ChatGPT Ads management outside that partner route. Neither agency on this shortlist is a named OpenAI partner.

Two things follow. First, GEO and ChatGPT Ads are separate line items, so “does this agency do ChatGPT Ads?” is a different question from “does this agency do GEO?”. Second, UK ads only reach Free and Go users (OpenAI Help Center, Damteq), so in our assessment a serious agency pairs ChatGPT Ads with LinkedIn, GEO or another channel that still reaches buyers on Plus, Business, and Enterprise plans. Large brands with a holding-company media contract will usually start with their network, and mid-market B2B teams with self-serve or an independent specialist.

Does it matter that Linkedist is not UK-based?

It matters less than the address suggests, and we name the practical points so buyers can weigh them. First, Linkedist is based in Vilnius, 2 hours ahead of London all year, so a 9:00 London call is 11:00 for our team. Second, Linkedist works with UK brands, and our CEO, Kotryna Kurt, is in the UK every month for events, networking and partnerships, so in-person meetings can be planned around those visits. Third, we have no UK office, so buyers who need a vendor on site at short notice should shortlist SEO Works ahead of us. Fourth, none of the 12 client cases published on linkedist.com is a UK case, so ask us for UK references directly. Fifth, we are an EU-based vendor, which some UK procurement teams handle easily and others do not.

Where we do earn UK shortlist consideration is scope. Linkedist runs LinkedIn organic, LinkedIn Ads, personal branding for executives, workshops, audits, LinkedIn Sales integration, AI search optimisation (GEO) across ChatGPT, Perplexity, Gemini, and AI Overviews, and ChatGPT Ads inside one team. For a UK B2B buyer whose growth loop is LinkedIn, one integrated vendor removes the coordination cost of hiring a UK PPC shop plus a UK GEO shop plus a LinkedIn agency. The core tradeoff is a UK office versus channel integration, and that tradeoff is honest on both sides.

When is each option the wrong fit?

Linkedist is the wrong fit when the buyer wants a UK office with in-person delivery, or when the priority is broad UK SEO and general digital work without LinkedIn as the primary channel. A UK ecommerce brand chasing Meta and Google Shopping will get more from a UK PPC specialist than from a LinkedIn-first team.

SEO Works is the wrong fit when the buyer wants a LinkedIn-first B2B team, because LinkedIn advertising is one paid social service inside its wider SEO, PPC and GEO offer.

Which agency on the best ChatGPT ads agency UK 2026 shortlist should you choose?

For UK B2B teams building ChatGPT Ads and LinkedIn together, Linkedist is the top pick on this shortlist, provided you are comfortable with an EU-based team that delivers in English and meets UK clients in person during its monthly UK visits. Choose SEO Works if you want paid ChatGPT Ads and GEO from one team with UK offices and LinkedIn is not central to your program. Given that UK self-serve is only a few months old, in our assessment it is worth agreeing short campaign cycles and 30-day reviews with whoever you pick, rather than locking a 12-month retainer.

FAQ

Is ChatGPT Ads live in the UK yet? Yes. ChatGPT Ads went live in the UK on 6 June 2026, according to PPC Land, with Dentsu as a named UK launch partner. Self-serve Ads Manager rolled out to UK advertisers between 19 and 22 June 2026 (Damteq, PPC Land). Advertisers can pay per impression (CPM) or per click (CPC), including conversion-optimised campaigns (OpenAI Help Center).

Who sees ChatGPT ads in the UK? Ads are shown to logged-in adults on Free and Go plans only. ChatGPT Plus, Pro, Business, Enterprise, and Edu accounts do not see ads (OpenAI Help Center, Damteq). This matters because senior B2B buyers often sit on Plus, Business, or Enterprise, so the pilot audience skews to lighter users.

How is a UK ChatGPT Ads agency different from a GEO agency? A ChatGPT Ads agency buys paid placements below ChatGPT responses. A GEO agency (generative engine optimisation) works to get a brand cited organically inside ChatGPT, Perplexity, and Google AI Overviews. Some UK agencies now offer both. Others offer only one.

Do I need a UK-headquartered agency to run UK ChatGPT Ads? No. What matters is whether the agency understands UK buyer intent and can operate in your working hours and contracting model.

How much does UK ChatGPT Ads cost per click? There is no fixed rate card yet. OpenAI’s Help Center recommends a starting max CPC bid of $3 to $5 USD, a range PPC Land and Damteq also report. Prices move fast: Adthena data reported by PPC Land on 23 July 2026 showed UK CPCs swinging by as much as 39% to 278% after self-serve opened, with no explanation of why.

How do I know if an agency has real UK ChatGPT Ads experience? Ask when their first UK campaign started (should be on or after 6 June 2026), whether they buy through the self-serve Ads Manager or the OpenAI Ads Solutions team, and whether they can show anonymised in-pilot metrics rather than only global US stats.
