Credentials are trust signals and they are also claims

Why they work so well

A visitor choosing between three similar firms is looking for a reason to trust one. A licence number, an insurance statement and a named certification do that faster than any paragraph.

They are specific, checkable and hard to fake, which is exactly why they carry weight.

They also answer a question many customers are too polite to ask directly.

They also help in search. A page naming a real licence, a real body and a real area reads as a specific business rather than a template.

They are also the cheapest trust signal available. The licence already exists; the only work is putting the number somewhere a customer can see it.

What your state may require

Many states require a licensed trade to show its licence number in advertising, and a website is advertising.

The requirement varies by trade and by state, including where on the page it must appear and what wording is needed.

Check your own board rather than copying another firm's layout. Nothing here is legal advice, and this is the area where a local rule most often applies.

Keeping them current

This is where sites fail. A certification lapses, a membership is not renewed, an insurance policy changes, and the page never does.

Put every credential on the site into one list with its expiry date, and check it twice a year. It takes ten minutes.

An expired credential on a live page is a claim you cannot support, and the fix is deleting a line.

Tie the check to something you already do. Renewal season, or the same week you review your insurance, so it never depends on remembering.

Build one list of every credential on the site with its expiry date. Ten minutes twice a year is the whole maintenance job, and without the list it never happens.

Say what it actually means

Members of a trade body are members. Being certified in one technique is not being certified overall. Insured means a particular kind of cover.

Stretching these is common and rarely deliberate. A logo in the footer implies more than a membership sometimes carries.

Say the specific thing. Certified for heat pump installation by the manufacturer beats the vague word approved.

Logos and permission

Most bodies and manufacturers have rules about using their mark, including size, color and whether it may appear near your own logo.

Some require current membership and withdraw permission when it lapses. Check before publishing, and again when you redesign.

Using a mark you are not entitled to is the fastest way to turn a trust signal into a complaint from the organization itself.

Manufacturer and trade body marks usually come with rules about size, color and placement, and permission that ends when the membership does.

Where to put them

The footer of every page for licence numbers, so they appear wherever somebody lands. A dedicated section on the about page for the fuller story.

Also near the point of decision. A licence number beside the contact form answers the doubt exactly when it arises.

Write them as real text rather than inside an image, so they can be read aloud, copied and checked.

• The footer of every page, so they appear wherever somebody lands
• A section on the about page with the fuller story
• Beside the contact form, where the doubt actually arises
• On any page selling the licensed work itself
• As real text, never inside an image
• With the issuing body named, not just a number

What the builder does

Credentials you supply publish as you gave them, and the builder will not invent a certification or infer one from your trade.

Every page passes a check that runs before anything publishes, validated against Google Search Essentials and modern web standards.

No check can know whether your licence lapsed last month. That is the twice yearly ten minutes, and it is the whole job.

Whether the claim is true stays with you, which is the division set out in honest claims.
