Best AI SEO Agencies in the UK (September 2026)

AI search is the youngest discipline in this register, and this small roster is unusually explicit about results, which makes the differences between the listings legible. Contra Agency publishes the fullest method: for Hudgell Solicitors it tracked 90 days to +11.85% visibility in AI Overviews, then described how—semantic analysis to build topic clusters, existing lawyer bios put to work as authority signals, answer-first headings, schema markup—and stated plainly that markdown and llms.txt are not live on the site yet. Catalyst Marketing Agency publishes harder numbers and less method: organic inquiries close to three times higher year on year for FreshGround, and marketing-qualified leads up 56% in June, without saying which questions were tracked or on which assistants. Push Group's obstetrics campaign took a domain rating from 1 to 19 in three months and won Best Use of AI in a Client Campaign at the UK Agency Awards 2025—but its BRITA page reuses that same statistics block verbatim, which cannot be true of a global filtration brand. NOVOS, Found and ClickSlice work the retail and performance end.

Read that last detail as the category's central risk. Where nobody agrees on the metric, reused statistics blocks and unbaselined visibility scores are easy to publish and hard to check. Published rates here sit at €85-170 an hour, which is retainer pricing rather than build pricing, so ask what the retainer buys in month six. Then ask which buyer questions were tracked, on which assistants, over what window, against which named competitors, and what the number was before. An agency reporting AI visibility without a baseline is reporting a screenshot.
