The quote form is where the money leaks

Every field on a form is a question you are asking a stranger before they have decided they trust you. Some of those questions earn their place. Most were added because somebody in the business wanted the answer in the inbox, not because the visitor needed to give it.

The honest way to audit a form is to go field by field and ask what happens if it is blank. If the answer is "we call and ask", the field is a preference, not a requirement, and it belongs in the conversation rather than on the page.

Second-guessing is the other leak. A form that gives no sign it worked sends people back to the site to try again, or worse, to a competitor while they wait. The confirmation should say what happens next and when, in the same voice as the rest of the site.

Captchas deserve their own paragraph. They stop a small amount of spam and a measurable amount of genuine enquiry, and on a phone in bad light they stop more of the second than the first. There are quieter ways to filter, and they are invisible to the person filling the form in.

None of this is a redesign. It is an afternoon of subtraction on the one page that turns traffic into work.
