Will AI recommend your plumbing business? Probably not, and here is why

Last Updated on August 12, 2026

We asked Google’s AI, ChatGPT and Gemini to name the best plumber in thirteen UK towns. The three engines agreed with each other just 8 percent of the time. Same town, same question, three different answers.

That is not a quirk. That is the market you now compete in, because a growing share of “plumber near me” moments never reach a results page at all. Someone asks an assistant, the assistant names two or three firms, and the job goes to one of them.

Try it on yourself

Open ChatGPT or Gemini and ask: “Who is the best plumber in [your town]?” Then ask “Should I use [your business name] for a boiler swap in [your town]?”

Three outcomes. You are named and described accurately: rare, and worth protecting. You are not mentioned at all: the common one. Or the AI describes you wrongly, old address, wrong services, a mixed-up namesake: the quietly dangerous one, because you will never see it happen.

The mistake: assuming AI finds you the way Google did

AI assistants do not crawl and rank the way search did. They lean on sources they can read and trust: structured data, consistent facts repeated across the open web, registers they can cite. Our thirteen-towns study found the engines disagree because there is no trusted source to agree on. For plumbing there is no public register of good firms, so each engine improvises from whatever fragments it has.

You cannot buy your way in. There is no ad slot in an answer. What you can do is become the easiest firm in your town to verify.

What actually moves the needle

Consistency first. Your business name, address and phone number should match everywhere they appear: your site, your Google Business Profile, directories. AI treats disagreement between sources as doubt, and doubt gets you dropped from the answer.

Verifiable facts second. A visible Gas Safe number, a Companies House record that matches your trading name, real reviews with real volume. Assistants repeat claims, but they weight sources that check claims. This is exactly why anyone can call themselves a plumber matters to your marketing, not just your customers: in a trade with no licence, being the checkable firm is a ranking advantage.

Readable structure third. Pages an AI can parse: services listed plainly, areas covered stated, FAQs in actual sentences. Every Whito listing is published with schema.org structured data and plain FAQs for precisely this reason, and the directory feeds the same facts to every engine, which is how the 8 percent problem gets fixed.

Where this sits in the framework

This is Start-stage work: being findable and easy to trust, in a channel that did not exist five years ago. It costs almost nothing and compounds. Buying leads while invisible to AI is the usual order mistake, tactics before structure, and it is why the leads trap bites hardest for firms nobody can verify.

The sharp takeaway

Ask the three engines about your business today. If you are missing or misdescribed, fix the boring things first: one consistent name, address and phone everywhere, a visible Gas Safe number, a claimed and checkable listing, reviews that keep arriving. AI recommends the firm it can verify. Make that firm yours, then check again in three months.

Free check: see whether AI recommends your business, or claim your listing in the Whito directory so every engine reads the same verified facts.
