The Credential Line That Gets Plumbers and Electricians Quoted by AI Search
Most trades sites just say licensed and insured. AI search cannot verify a phrase, only a number, and here is exactly which credential details actually get plumbers and electricians quoted.
A homeowner asks ChatGPT to recommend a licensed electrician nearby and the assistant names three companies. Two of the three list an actual license number on their site. The third does not get named at all, even though the work is just as good, because a model cannot verify a claim it cannot read.
Licensed And Insured Is Filler To AI Search
Every trades website says the same three words: licensed and insured. The phrase appears so often that it carries no information at all. A large language model pulling facts for an answer treats an unverifiable claim as noise and moves on to the next site that gives it something concrete to repeat, such as an actual number.
1. The Four Details AI Search Actually Looks For
Getting quoted is not about proving you are qualified. It is about stating the proof in a form a model can lift and repeat with confidence. That means specific figures, not adjectives.
- The trade license or registration number itself, not just the word licensed
- The public liability insurance amount you carry, stated in pounds or euros
- The scheme or certification body you belong to, such as Gas Safe or NICEIC, with your registration number
- How many years you have operated under your current business name
2. Put The Number Where A Model Will Find It
A credential number buried on a certifications page three clicks deep might as well not exist. State it in plain text near your contact details, on your homepage, and on every service page where the credential is relevant. Repeat it rather than linking to it once, since a model reads each page on its own and does not follow a trail of links to piece together a fact.
| What most trades sites say | What AI search can actually quote |
|---|---|
| Fully licensed and insured for your peace of mind | Nothing specific enough to repeat as a fact |
| Registered electrician, NICEIC number 123456, ten years trading as your business name | A precise claim it can state with your business name attached |
3. A Badge Image Does Not Count As Text
Plenty of trades sites display a certification logo in the footer as a small image. A person recognizes it instantly. A language model reading the page for facts usually cannot, since the credential lives inside a picture rather than in the text of the page. If a badge is the only place a certification appears, write the same fact out in words next to it.
A badge image proves something to a visitor. It proves nothing to a model that cannot read pictures.
The Takeaway
AI search rewards specificity over reassurance. Four concrete details, your license number, your insurance figure, your certification body, and how long you have traded, written out in plain text, do more for how ChatGPT and Google's AI Overview describe your business than any amount of the phrase licensed and insured ever will.
