Licensed, insured, and able to prove it
A customer checks three things before ringing, in roughly the same order every time: are you a real business, are you covered if something goes wrong, and has anybody else used you. The words licensed and insured answer none of them, because every site says them. A licence number, a certificate you can send the same day, and two references a stranger can check are what move somebody from reading to ringing.
Every trade website in the country says licensed and insured. The phrase has been used so often that it now carries almost no information: the firms that are, the firms that are not, and the firms that were until the policy lapsed all write exactly the same two words.
So the question is not whether to say it. It is what to put next to it that somebody can actually check, because the whole value of a credential is that it is checkable.
The order people check in
Watch somebody decide between two contractors and the sequence is remarkably consistent.
First: is this a real business. A trading name, a phone number that gets answered, an address or at least a service area, and some sign that the firm existed last year. This takes about four seconds and most of it happens before they read a word.
Second: am I covered if this goes wrong. For anything that involves entering the house, digging, or touching a roof, this is the one that stops people. They are not imagining you being careless. They are imagining a ladder, a window, and a conversation about who pays.
Third: has anybody else used you. Reviews, photographs of work, a reference. This is where most firms put all their effort, and it is the third thing, not the first.
The order matters because it tells you what belongs on the first screen. Proof of work is the easiest of the three to produce and the least urgent to the reader. The first two are the ones that get skipped.
A licence number beats the word licensed
If you are licensed, print the number.
It is one line. It converts a claim everybody makes into a fact somebody can verify, and the act of publishing it is itself the signal: nobody prints a number they do not have.
In Illinois this matters more than in most states, and it differs by trade. Plumbers are licensed by the state, through the Department of Public Health. Roofing contractors are licensed by the state too, which is unusual and exists largely because of the crews that follow storms. Electricians are not: there is no statewide electrician licence here, and licensing or registration is handled municipality by municipality, with Chicago running its own. General contractors are the same, registered village by village where they are registered at all.
That last group is where most contractors sit, and it is why the honest version of this section is not always a number. If your trade has no state licence, the useful sentence is the list of municipalities you are registered or bonded in. It is specific, it is checkable, and it tells a customer in Naperville something that the word licensed does not.
If you hold a certification from a manufacturer, name it with the manufacturer rather than showing a row of logos. On most systems it is the thing that allows you to offer the longer warranty, and it is one of the few claims a customer can confirm on somebody else’s website.
Fully insured is a claim, a certificate is proof
Here is the test that separates the firms that are insured from the firms that believe they are: can you send a certificate today.
Your insurer issues one. It names the policy, the limits and the dates, and it can be emailed in the time it takes to ring the broker. A firm that is genuinely covered can produce it within a few hours. A firm that has been meaning to renew cannot, and that is the gap the customer is worried about without knowing how to ask.
So the sentence worth putting on your site is not “fully insured”. It is closer to: general liability and workers’ compensation, certificate available on request, usually the same day.
Three practical notes, because this is the part contractors get caught by:
Do not publish the certificate itself. It carries your policy number and your broker’s details, and it has a date on it that will be out of date in twelve months while your website is not. Offer it, send it when asked.
Builders and property managers will ask to be named. Being added as an additional insured on your policy for a specific job is routine, your broker does it in a day, and being unable to do it is one of the quieter reasons a sub does not get on a list. If you work for builders at all, say on the site that you can do it.
Workers’ compensation is the one people forget to mention. For a homeowner letting somebody onto a ladder it is the more frightening of the two, because the question underneath is whether an injured worker ends up being their problem.
References without publishing a client list
Most contractors do not want a page naming every builder they work for, and they are right not to want it. Competitors read it, and some clients would rather not be listed.
You do not need one. What a customer wants is not the list, it is evidence that the list exists.
Named work, not named clients. “Two hundred square foot patio in Lisle, 2025” with a photograph is proof without naming anybody. The town and the year are what make it real.
References on request, with a number. “We can put you in touch with two customers from the last six months” is better than a page of testimonials, because it is falsifiable and testimonials are not. Then make sure it is true, and ask the two people first.
Point at reviews you do not control. A link to your Google profile is worth more than any quotation you typed yourself, for the simple reason that you could not have written it. If you have few reviews, that is an argument for asking your next ten customers, not for writing your own.
Say how long you have been going. “Trading since 2014” costs nothing and answers the question underneath all of this, which is whether you will still be reachable if something goes wrong in two years.
What to do when you started last year
This is the section most articles leave out, and it is the one a newer contractor actually needs.
You cannot claim a history you do not have, and you should not try, because it is the easiest thing in this whole list to catch. What you can do is be specific about what is true.
Years in the trade, rather than years in business. “Fifteen years as a journeyman, trading on my own account since 2025” is a stronger sentence than either half alone, and it is honest.
Your licence or registration, which you have from day one and which carries exactly the same weight as the twenty-year-old firm’s.
Your insurance, likewise. It is the same cover and the same certificate.
Photographs of the work you did last month, with towns and dates. Three recent jobs presented properly beat a vague claim about hundreds of them.
And a response time you will actually keep. A new business can offer something an established one often cannot: answering the phone, and ringing back the same day. Say it, then do it. It is the only credential on this page that a competitor with twenty years cannot simply buy.
Where we would tell you not to bother
Two things get sold under this heading that are not worth your money.
Trust badges and seals. The small graphics that say verified or secure, sold by companies that verify very little. Customers have learned to ignore them, and the few who click one find a page that confirms you paid for a badge. A licence number does more and costs nothing.
A membership you joined for the logo. Trade associations can be genuinely useful and some are worth every penny. One you joined purely to put a badge in your footer is a subscription buying you a small image. If you cannot say what the membership does for you in one sentence, it is not a trust signal, it is a direct debit.
The honest version of all this is that the credentials you already hold, written out properly, do almost all the work. Nothing on this page needs buying.
What the page should actually say
Put this where somebody sees it without scrolling, or close to it:
- The trading name and how long you have been going.
- The licence or registration, with the number, or the municipalities you are registered in if your trade has no state licence.
- Insurance in plain words, with the offer of a certificate.
- The towns you cover.
- A phone number that is a link, not a picture.
That is five lines and a phone number. It is also, in our measurements of local sites, the section most often missing entirely, which means it is one of the cheapest advantages available to you.
If you are building the site yourself, put these five things on the home page before you do anything else, and read the nine things a local service website needs for the rest of it. If you are deciding whether to have a site at all, start with word of mouth works, so do you need a website, which includes the cases where the answer is no. And if you already have a site but are not sure who controls it, who built your website is the one to read first.
