Generative engine optimisation in the UK: what is different for UK B2B firms.

The short answer.

For a UK B2B firm, generative engine optimisation means making sure AI engines can find, trust and repeat accurate facts about you when a UK buyer asks for a supplier. The general method is the same everywhere, and our guide to generative engine optimisation covers it. This article covers only what changes when your buyers are in the UK.

Four things change. First, timing: each AI product arrived in the UK on its own date. Second, sources: UK answers can draw on UK public records, trade bodies, regulators and review sites that a US-focused plan ignores. Third, signals: your domain, spelling and place names tell an engine which country you serve. Fourth, rules: consumer protection law now bans fake reviews and paid-for reviews not clearly marked as incentivised, and UK GDPR, with the ICO’s guidance on AI, is relevant when AI work touches personal data.

Our generative engine optimisation services start in the same place, with the questions buyers actually ask. If any term here is unfamiliar, the AI search glossary defines it in a line.

How UK buyers use AI now.

UK buyers already see AI answers in ordinary searches, and many now use chatbots as well.

Ofcom’s Online Nation report, published on 10 December 2025, found that “about 30% of searches now show AI overviews”, and that 53% of adults said they see these summaries often. The same report counted 1.8 billion UK visits to ChatGPT in the first eight months of 2025, up from 368 million in the same period of 2024.

Business buyers are moving too, though the best UK figure we found is second-hand. A Trax Tech write-up of 11 December 2025 reports that, in a Magenta Associates survey, 66% of UK senior decision-makers with B2B buying power said they use AI tools to research and evaluate potential suppliers. The write-up does not give the sample size and we could not read the original report, so treat the figure as indicative only.

UK firms are adopting AI themselves. The ONS reported on 20 July 2026 that self-reported AI use among UK businesses with 10 or more employees had risen from around 12% in late 2023 to around 35%, with 58% in information and communication compared with 13% in construction.

What is live in the UK, and since when.

Every major AI search feature a B2B buyer is likely to use is now available in the UK, but each arrived on its own date. Google’s AI Overviews, for example, reached the UK only on 15 August 2024.

Any baseline you keep should note which features were live in the UK on each date.

Google described AI Mode as a way to “address your most complex, multi-part questions and follow-ups”. Our guide to what Google AI Mode means for B2B sites covers how it differs from AI Overviews. Paid placements are a separate decision, covered in our guide to advertising on ChatGPT.

Why a UK answer can differ.

An AI engine builds its answer from the question it is given and the pages it finds. A UK buyer who leaves out the country, uses UK terms or names a UK city can get a different list from a US buyer asking the same thing.

Engines search the web on the buyer’s behalf and read a handful of pages; our explainer on how ChatGPT decides which companies to recommend covers the mechanics. Three details shape which pages get read.

• ✓Words. UK buyers say “solicitor”, “chartered surveyor”, “managed IT support”, “VAT-registered” and “Cyber Essentials”. If your pages only use US terms, they match fewer UK questions.
• ✓Places. “In Manchester”, “across the North West” or “for UK councils” narrows the search. Pages that name the places and sectors you serve can be matched to it.
• ✓Credentials. UK buyers ask for UK credentials: regulated by a UK body, on a framework, holding a UK certification. An engine can only name you for these if a page states them.

The third prompt is easy to forget: buyers ask engines to check a supplier, not only to find one. If the engine gets you wrong, our guide to fixing AI answers that describe your company wrongly deals with it.

The UK sources AI answers draw on.

A UK answer can draw on UK public records, regulator registers, trade bodies, UK directories and review sites, and UK trade press. Each is a place where an engine, or a buyer checking the engine, can confirm what your website says.

Most of the sources AI answers cite for B2B questions are company websites: in our study of where AI answers get their sources, about 91% were. But buyers check answers against independent sources, and for a UK firm these come first.

Companies House is the UK’s common reference

Anyone can look up basic company details for free, including the “registered address and date of incorporation”, officers and previous names. A mismatch between that record and your site is easy for a buyer to spot.

The record is also changing. In August 2025 Companies House confirmed that legal requirements for directors and people with significant control to verify their identity would start on 18 November 2025, phased in over 12 months. Keep the record current, and use the same legal name in your site’s footer, contact page and terms.

Regulators and trade bodies

In regulated sectors, the register is often the first thing a careful buyer checks. The FCA describes its register as a “public record of firms, individuals and other bodies” that are or have been authorised. Advisers and wealth managers should read our guide to financial adviser marketing in AI search, and professional firms our guide to how advisers get recommended by AI.

The wider set of third-party sources is ranked by effort in our guide to the off-site sources AI engines trust. The play on matching facts across profiles gives a quick audit.

.co.uk, .com and UK pages.

A .co.uk domain tells search engines your site is meant for the UK. A .com does not, so a .com site has to say so on the page and in its structure.

Google’s guidance on multi-regional sites says country-code domains “provide a strong signal to both users and search engines that your site is explicitly intended for a certain country”, and that generic domains “aren’t associated with specific locations”. It also recommends hreflang or sitemaps to tell Google which pages apply to which locations or languages. Google also says that to appear as a link in AI Overviews or AI Mode, a page “must be indexed and eligible to be shown in Google Search with a snippet”, so the same signals still apply.

Google’s table lists country domains as giving “clear geotargeting” but able to “only target a single country”: the trade-off for UK firms with US ambitions. Spelling matters too; a UK page in US spelling reads as written for someone else.

Whatever the domain, make sure AI crawlers can reach the pages. The play on AI crawler access covers robots.txt, and the play on consistent names covers the trading-name problem many UK firms have.

Reviews under the DMCC Act.

Reviews feed AI answers and the buyers who check them, and UK consumer protection law now explicitly bans fake reviews. Collect them carefully.

The CMA said on 7 April 2025 that the Digital Markets, Competition and Consumers Act 2024 “includes an explicit ban on the posting and commissioning of fake reviews”, and that under the new regime it can decide for itself whether consumer protection laws have been infringed and fine a company up to 10% of its global turnover. On 27 March 2026 the CMA reported a sweep of over 100 review publishers, advisory letters to 54 firms, and investigations into five businesses over fake and misleading reviews. It listed “paid-for reviews that are not clearly marked as incentivised” among the practices banned under the DMCC Act since April 2025.

The Act is consumer protection law; whether a given B2B review falls within it is a question for your legal adviser. The checklist below is cautious good practice, not legal advice.

A cautious review process

• ✓Ask every customer, at a fixed point such as project sign-off or renewal, not only the happy ones.
• ✓Never write, buy or swap reviews, and never ask staff to review their own firm.
• ✓If you are thinking of offering anything for a review, take advice first, and make sure any such review is clearly marked as incentivised.
• ✓Show all reviews you publish on your own site, not a hand-picked set presented as the whole picture.
• ✓Reply to criticism factually. A calm reply is also source material.

The same caution applies to claims on your own pages. Where the CAP Code applies to your marketing, rule 3.7 says that before publishing, marketers “must hold documentary evidence to prove claims that consumers are likely to regard as objective and that are capable of objective substantiation”. The play on review directories has a short audit.

Data protection and the ICO.

GEO work rarely needs personal data, and it is simplest to keep it that way. When it does touch personal data, UK GDPR and the ICO’s guidance on AI apply.

The ICO says its guidance on AI and data protection was updated on 15 March 2023, and notes that because of changes made by the Data (Use and Access) Act, it “is under review and may be subject to change”. Two points in it matter for marketing teams. It says that “in the vast majority of cases, the use of AI will involve a type of processing likely to result in a high risk to individuals’ rights and freedoms”, which will trigger the legal requirement for a data protection impact assessment, assessed case by case. And it says organisations that determine the purposes and means of processing “will be controllers regardless of how they are described in any contract”.

This is not legal advice; follow your own data protection policy. For the tracking side, our guide to tracking AI referrals from GA4 to pipeline shows how to report without building new personal data stores.

A UK prompt panel method.

A UK prompt panel is a fixed list of the questions your UK buyers ask, written in UK terms, run on the same engines each month so you can count how often you are named and which sources are cited.

The general method (choosing questions, recording a baseline, re-measuring) is in our guide to checking your AI search visibility, and the play on building a question panel covers panel size. The UK version adds four rules.

1. Write prompts with and without “UK”. Many UK buyers never say the country, so test both.
2. Use real UK place names and terms. Name the cities and regions you serve, and the UK credentials buyers ask for.
3. Include one checking prompt. Ask the engine whether your firm is registered, how long it has traded and what its reviews say. Compare the answer with Companies House.
4. Record the sources, not only the names. Note whether cited pages are UK sources, US sources or your own site. A US-heavy source list is a sign your UK proof is thin.

Run each prompt more than once. Answers vary from run to run, so a single result is a sample, not a position; the play on repeated runs explains why. If you would rather see a dated baseline before doing this yourself, ask for a free AI visibility report on a sample of your UK buyers’ questions.

The UK prompt panel builder.

Choose your sector, where your buyers are and who they are. The builder writes a starting panel in UK terms and works out how many runs a month it means. Nothing you choose is sent anywhere.

The prompts are illustrative starting points. Replace the bracketed parts, rewrite the wording to match how your own buyers talk, and keep the panel fixed once you start measuring, so that month-on-month changes mean something.

What to fix first.

Fix the facts that a buyer or an engine can check against an official UK record first, then the signals that say you serve the UK, then reviews and wider mentions.

When you re-run the panel, look at the source list as well as the names. How quickly engines reflect changes is outside your control and varies by engine.

If you are choosing outside help, our list of questions to ask an SEO or AI search agency works for a UK GEO agency too; ask to see a dated UK baseline and the source lists behind it. If you would like this run for you, our GEO and AEO services start from a dated baseline of buyer questions and cited sources, then cover clear company information and tracking AI referrals through to enquiries.

Questions UK firms ask.

Is generative engine optimisation different in the UK?

The method is the same, but the inputs differ. UK answers can draw on UK records, regulators, trade bodies and review sites, UK buyers use UK terms and place names, and UK rules on reviews and data protection apply.

Are Google AI Overviews and AI Mode available in the UK?

Yes. Google expanded AI Overviews to the UK on 15 August 2024, and AI Mode began rolling out in the UK on 28 July 2025 as a tab on the results page.

Does ChatGPT recommend UK companies?

It can, when the question and the pages it finds point to UK firms. Test prompts both with and without the country, because many UK buyers leave it out.

Do I need a .co.uk domain for AI search?

No. Google says a country-code domain is a strong signal of the target country, but a .com can serve UK buyers well if its pages state UK service clearly and, where there are several markets, use hreflang between matching pages.

Can we offer incentives for reviews in the UK?

Take legal advice for your own case. The CMA lists paid-for reviews that are not clearly marked as incentivised among the practices banned under the DMCC Act 2024, and whether that applies to your reviews is a question for your adviser.
