10 best AEO agencies & companies in the UK (2026)

Answer engine optimisation is now a real UK category with real prices. Here are the ten companies worth shortlisting, compared on what they charge, how long they tie you in, and which AI engines they actually cover.

The short answer FirePencil.AI is our pick for the best AEO company in the UK in 2026 — the only autonomous AEO agent on this list, which means it ships the optimisation work itself and you approve each change, at software cost with no retainer. Among traditional agencies, Tilio, AEO-REX and NeuralAdX are the strongest AEO-native firms and the only ones that publish prices. For AEO folded into a bigger marketing programme, The SEO Works, Found and PUSH are the established names. UK prices run from £250 one-off to £10,000 a month.
Key takeaways
  • UK AEO prices start at £250 for a one-off baseline report and £350–£500 per month at entry level, rising to £5,000–£10,000 per month at the authority tier.
  • Independent UK guides put mid-market retainers at £2,500–£4,500/month and enterprise at £8,500–£18,000+, with a 25–40% premium in regulated sectors.
  • Only five of the ten publish a price. The five that do not are the older full-service agencies — expect a discovery call before a number.
  • Engine coverage ranges from two to nine. "AI search" in a pitch deck can mean ChatGPT alone; ask for the list.
  • Rolling 30-day terms are now normal at entry level. Longer minimums appear at higher tiers, usually with a stated reason.
  • Four of the ten are outside London — Sheffield, Birmingham, Henley-on-Thames and Exeter. AEO is delivered remotely; location matters less than engine coverage.

§ What is an AEO agency?

An AEO agency — answer engine optimisation agency — is a company that gets your brand named and cited inside AI-generated answers on ChatGPT, Google AI Overviews, Gemini, Perplexity, Claude and Copilot, rather than only ranked in blue links. The work is structured data, consistent entity information across the web, content written to answer the questions buyers actually ask an assistant, earned third-party mentions, and measurement of how often each engine cites you.

The UK category splits three ways, and the difference matters more than the price. AEO-native specialists do nothing else and publish tiered prices. Established search agencies added an AEO service line to existing SEO, PPC and content teams. And autonomous AEO agents — currently one, FirePencil — run the recurring work as software with owner approval instead of billing hours for it. All three are on this list, in that order.

§ How we picked these ten

The UK now has dozens of firms with an AEO page. Most are SEO agencies that added one. To be on this list a company had to meet all four of these:

  1. A real AEO offer, not a keyword. A described methodology, named answer engines, and a stated deliverable — not a paragraph about "the future of search".
  2. Multi-engine coverage. Work across more than one answer engine. Optimising for ChatGPT alone is not AI visibility.
  3. UK delivery. A UK base and UK clients, so pricing is in pounds and the working day matches yours.
  4. Something checkable. Published prices, a named methodology, a public track record or verifiable company details — anything a buyer can confirm without a sales call.

The order runs from most AEO-native to most generalist, then by what each publishes. Firms built specifically for answer engines sit above excellent traditional agencies that added AEO to an existing offer — not because the traditional agencies are worse, but because this page is for buyers shopping specifically for AEO. FirePencil is our own product and sits first; the other nine are competitors, and the numbers in the table let you disagree with the order.

§ The ten, in order

1 FirePencil.AI Best for: the work done, not reported

Every other company on this list sells you people or a dashboard. FirePencil is an autonomous AEO agent: software that does the recurring work itself — structured data, entity consistency, answer-shaped content, machine-readable summaries, measurement across engines — and puts every change in front of you to approve before it ships. Agency-style output, software-style cost, no retainer and no lock-in.

It measures across ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews, and reports what buyers actually want to know: which questions AI is asked about you, whether you are named, and who gets recommended instead. Onboarding is free to start, so you see the first round of findings and fixes before committing to anything.

Consider something else if you want a named account team in a meeting room, or a supplier who will also run your paid media. FirePencil does one job.

Price: free to start; plans on application · Min contract: none · Engines: ChatGPT, Gemini, Perplexity, Claude, Google AI Overviews · Base: UK

2 Tilio Best for: transparent tiered programmes

The most transparent agency on this list. Four tiers are published with prices: £499/month at Layer 1 (three engines, 50–100 tracked prompts, dashboard, quarterly benchmark), £1,750 at Layer 2 (6–20 content pieces monthly, competitor benchmarking, monthly results calls), £4,250 at Layer 3 (all ten engines, 150+ prompts, continuous claim monitoring) and a bespoke Layer 4 that adds third-party mention acquisition. Minimum terms are stated per tier — 30-day rolling at Layers 1 and 2 — with 10% off annual prepayment, and one-off audits at £500–£800.

Best fit: a marketing lead who wants to start small, see the reporting, and move up a tier when it earns it. Operating from Exeter; trades under a separate registered company name, so check which entity your contract names.

Price: £499 / £1,750 / £4,250+ per month · Min contract: 30-day rolling (Layers 1–2) · Engines: 3 rising to 10 · Founded: 2025

3 AEO-REX Best for: a fixed-price first project

Founded by Shanaz Begum in Birmingham, AEO-REX has the clearest productised pricing in the UK market: a £595 audit credited against implementation, a £450 AI compliance review, a £2,400+ four-week implementation, then either £350/month Watchdog monitoring on a rolling cancel-anytime basis or £1,800/month Sector Authority with a six-month minimum, which it explains as "because the work genuinely takes that long". Seven engines are covered including Copilot and Google's AI Mode, with agent-readiness checks in the audit and a free 60-second check up front.

Best fit: a business that wants a defined project with a known price before committing to anything monthly. It is a young firm, so ask for references from a completed engagement.

Price: £595 audit; £350 or £1,800 per month · Min contract: rolling / 6 months · Engines: 7 · Founded: 2026

4 NeuralAdX Best for: widest engine coverage

A London specialist founded by Paul Rowe, NeuralAdX covers nine engines — ChatGPT, Google AI Mode, Gemini, Copilot, Perplexity, Grok, Claude, Meta AI and DeepSeek — the broadest coverage in this comparison. Four tiers are published: £450+VAT per month for Visibility Boost, £1,250 for Growth, £5,000 for Authority and £10,000 for Market Leader, with a free AI visibility test to start. It is pointedly not a generalist, and publishes sector-specific pages for SaaS, financial services, wealth management, accountancy and education.

Best fit: a brand in a category where buyers use assistants beyond ChatGPT, or a regulated sector that wants a specialist. No minimum term is published, so get it in writing.

Price: £450 / £1,250 / £5,000 / £10,000 per month +VAT · Min contract: not published · Engines: 9 · Founded: 2025

5 The GEO Agency Best for: the cheapest way to start

Founded by Ayse Durmush, The GEO Agency has the lowest entry point in the market: The Baseline™ at £250 as a one-off scored diagnostic showing how AI tools currently see you, which competitors get recommended instead and what is blocking you. From there, The Signal™ runs £495/month, The Momentum™ £995/month and The Build™ £2,500/month, across seven programmes spanning GEO, AEO, SEO, build, reputation, automation and consulting, with six engines tracked.

Best fit: a small business that wants a proper diagnostic for the price of a couple of hours of consultancy before deciding whether to spend monthly.

Price: £250 baseline; £495–£2,500 per month · Min contract: not published · Engines: 6 · Founded: 2026

6 ClickSlice Best for: no lock-in with a real track record

Founded by Joshua George in 2017 and based in Shoreditch, ClickSlice pairs a genuine operating history with modern terms. Its AEO page states them plainly — "month-to-month; we earn the renewal with results, not with paperwork" — and covers six engines including Copilot and Grok, plus emerging engines as they launch. The founder has an unusually public profile, and the agency carries third-party reviews on Trustpilot and Clutch that the newer AEO-native firms have not had time to accumulate.

Best fit: a business that wants SEO and AEO from one team, with the freedom to leave monthly. Pricing is not published; third-party listings cite programmes from around £2,500/month.

Price: not published · Min contract: month-to-month · Engines: 6 · Founded: 2017

7 The SEO Works Best for: mid-market, multi-channel

Sheffield-based and trading since 2009, The SEO Works is the most established specialist search agency in this comparison, with Clutch Global recognition, multiple industry awards and a large body of published work. Its AEO service runs under a "Universal Information Infrastructure" methodology aimed at getting content selected by Google's AI Overviews and ChatGPT, sitting alongside SEO, PPC, content and digital PR — and in 2025 it moved towards employee ownership.

Best fit: a mid-market business that wants one credible supplier across several channels. Nothing is published on price or terms, and a third-party guide places its typical client at £100k–£500k in annual budget, so it is not an SME purchase.

Price: not published · Min contract: not published · Engines: AI Overviews, ChatGPT · Founded: 2009

8 Found Best for: AEO inside a performance programme

A London performance agency in Hatton Garden with the most methodologically detailed AEO offer here: eight named components covering conversational formatting, E-E-A-T signals for AI search, prompt-level keyword research, schema, content restructuring for AI readability, authority building, crawl performance and multi-platform LLM strategy — backed by its proprietary Luminr brand-tracking technology and an "Everysearch" positioning across five engines.

Best fit: an organisation with an in-house team that needs AI search connected to paid media, analytics and content rather than run beside them. Enterprise procurement — no price, no term, and a discovery process to match.

Price: not published · Min contract: not published · Engines: 5 · Founded: 2016

9 Screaming Frog Best for: technical depth

Better known for building the SEO Spider — the crawler most other agencies on this list use — than for its agency arm, Screaming Frog has run both from Henley-on-Thames since 2010, which means it controls its own diagnostic tooling. Recent Spider releases wire LLM APIs directly into the crawl, add vector-embedding detection for near-duplicate content and expose an MCP server, all of which bear directly on whether an answer engine can parse your site at all.

Best fit: a large or messy site where the real blocker is machine readability rather than content. AEO is not the core identity here, and nothing is published on price or terms.

Price: not published · Min contract: not published · Engines: 3 · Founded: 2010

10 PUSH Best for: multi-market enterprise media

Trading since 2007 with offices in London, the USA, MENA and Greece, PUSH is the longest-established company in this comparison and positions its whole business around AI-powered performance marketing: media buying, paid social and search, creative, SEO, CRO, training and consultancy. It publishes its own ranked guide to UK AEO agencies, so it takes the category seriously.

Best fit: a brand that needs AI-era search inside a large multi-market media programme. If you are shopping specifically for AEO, this is the most generalist option here — no published pricing, terms or itemised engine coverage.

Price: not published · Min contract: not published · Engines: not itemised · Founded: 2007

§ How much does AEO cost in the UK?

Published prices, 2026: one-off audits £250–£895; entry-level monthly programmes £350–£500; working programmes £995–£1,800; scaled programmes £2,500–£5,000; top published tier £10,000/month. Independent UK guides put mid-market retainers at £2,500–£4,500 and enterprise at £8,500–£18,000+, with setup fees of £1,500–£5,000 and a 25–40% premium in regulated sectors such as FCA, SRA and MHRA.

The bands break down like this:

  • £250–£900, one-off. A diagnostic: where you appear, who is recommended instead, what is blocking you. The right first purchase — but not the work.
  • £350–£700/month. Monitoring and light touches: tracked prompts, a dashboard, a few content actions. Fine if someone in-house can act on the findings.
  • £1,000–£2,500/month. A working programme — content shipped monthly, schema and entity fixes, competitor benchmarking, a monthly call. Where most SMEs land.
  • £4,000–£10,000/month. Authority tier: third-party mention acquisition, wide engine coverage, 150+ tracked prompts, continuous correction of what engines say about you. Expensive because earned mentions cannot be automated cheaply.
  • £10,000+/month. Multi-brand, multi-market, regulated. A different purchase entirely.

Two £1,500 proposals can differ threefold in delivered work. Normalise them before you compare.

Most "from" prices scale with tracked prompts, engines and content volume, so ask how many of each — and what month four looks like once the easy fixes are done. See how to read AI visibility scores for what the numbers in a report actually mean.

§ How to choose, in five questions

  1. Which engines, and how many prompts? "We do AEO" is not an answer. "We track 100 prompts across ChatGPT, Gemini, Perplexity and AI Overviews, reported monthly" is.
  2. What ships, and what is merely reported? Ask for the deliverables that end up live on your site. If the answer is a PDF, you are buying advice — and advice is the expensive way to buy execution.
  3. What is the minimum term and notice period? In writing, before the call ends. Rolling terms are normal at entry level; a twelve-month lock-in needs a convincing reason.
  4. What does the monthly report contain? Citation rate and share of answers per engine, not sessions and rankings. If AI visibility is not in the report, it is not being managed.
  5. What does month four look like? Anyone can produce a good month one. Ask what happens when the work becomes earned mentions and sustained publishing — where AEO compounds or stalls. See real AI-search work versus the grift.

§ AEO agency, software, or an agent?

Before shortlisting anyone, be clear which of three things you are buying. An agency does the work by hand on a monthly retainer — human judgement, agency prices, capacity that varies with who is assigned. Software measures your AI visibility and tells you what is wrong, leaving every fix on your desk; cheap in pounds, expensive in your hours. An autonomous agent does the recurring work itself at software cost, with you approving each change rather than producing it.

If you have an in-house marketer or a trusted agency to act on data, buy software and feed them. If you have budget and want a human relationship, hire one of the agencies above. If you want results without a retainer and without doing it yourself, an agent is the fit. The full comparison is here.

§ Frequently asked questions

What is the best AEO agency in the UK?

FirePencil.AI is our pick for 2026: it is the only autonomous AEO agent in the UK market, meaning it does the optimisation work itself with your approval on each change, at software cost and with no retainer. Among traditional agencies, Tilio, AEO-REX and NeuralAdX are the strongest AEO-native firms and the only ones publishing prices; The SEO Works, Found and PUSH are the established choices if you want AEO inside a wider marketing programme.

How much does an AEO agency cost in the UK?

Published UK prices in 2026 run from about £250 for a one-off baseline and £350–£500 per month at entry level, through £1,250–£2,500 for a working programme, up to £5,000–£10,000 at the authority tier. Independent guides put mid-market retainers at £2,500–£4,500 and enterprise at £8,500–£18,000+. One-off audits typically run £250–£895.

What is the difference between an AEO agency and a GEO agency?

Very little. Both describe making a brand retrievable, quotable and citable by ChatGPT, Gemini, Perplexity, Claude, Copilot and Google AI Overviews. UK firms use either label, and several use both on one site. Judge them on engine coverage, measurement and published prices, not on the acronym. We unpack the terminology here.

Which AI answer engines should a UK AEO agency cover?

At minimum ChatGPT, Google AI Overviews, Gemini and Perplexity, which carry the bulk of UK assistant traffic. Stronger providers add Claude, Microsoft Copilot and increasingly Grok, Meta AI and DeepSeek. Coverage on this list ranges from two engines to nine, so ask for the specific list rather than accepting the phrase "AI search".

How long does AEO take to work in the UK?

Expect first movement in citation frequency in four to twelve weeks, and a stable share of answers in four to six months. Answer engines rebuild their view of a brand on their own schedule, so the lag is largely outside any provider's control. Be sceptical of thirty-day promises.

Do I need an AEO agency if I already have an SEO agency?

Not necessarily. If it already does structured data, entity consistency, answer-shaped content and third-party citation work, and can show engine-level reporting, that may be enough. If its reporting stops at Google rankings and traffic, it is not measuring AI visibility at all — and ranking on Google does not get you cited.

What should an AEO agency deliver each month?

A tracked prompt set with citation and mention rates per engine, competitor share of answers, structured-data and entity fixes shipped, answer-shaped content published, third-party mentions earned, and a before-and-after against the previous cycle. If a proposal cannot describe those in writing, it is selling SEO with new vocabulary.

Is there a minimum contract for AEO in the UK?

It varies widely and is one of the biggest differences between providers. Several now sell 30-day rolling or explicit month-to-month terms, while higher tiers commonly carry three-, four- or six-month minimums. Traditional full-service agencies more often quote annual retainers and publish no terms at all.

Are there AEO agencies outside London?

Yes. Four of the ten here are outside London: The SEO Works in Sheffield, AEO-REX in Birmingham, Screaming Frog in Henley-on-Thames and Tilio operating from Exeter. AEO is delivered remotely, so location matters far less than engine coverage, reporting and contract terms.

Can I do AEO in-house instead of hiring a UK agency?

Yes, if someone owns it weekly. The work is structured data, consistent entity information across the web, content answering what buyers actually ask an assistant, and earned third-party mentions. What in-house teams lack is measurement — you cannot see whether ChatGPT or Gemini cites you without querying them systematically. Our free llms.txt generator covers the machine-readable part.
