Speed to lead: why response time matters

What a faster reply is worth, with the maths shown

Here's the example from the Norwegian column, converted. Say your firm gets 30 enquiries a month and the average job is worth $2,400, which is roughly the 25,000 kroner I used in the original.

If you convert 25% of them, 30 enquiries become 7.5 jobs a month, and 7.5 × $2,400 is $18,000 a month.

Now lift the conversion to 35% by being the one who answers first. Nothing else changes. Say the same 30 enquiries: 10.5 jobs, × $2,400, $25,200 a month.

The difference is $7,200 a month. Over your year, $86,400. Not one extra pound or dollar went on ads to get it.

Two things to be honest about. That average job is a Norwegian one, with bathroom refits and boiler swaps in it. If yours is closer to HomeAdvisor's June 2026 figure of $341 for a US plumber visit, divide every line by seven. The shape holds. And 25% to 35% is an assumption, not a measurement. Ten points is modest next to the HBR gap between a one-hour reply and a next-day reply. Run your own numbers in the calculator.

The four steps: measure, promote, confirm, chase

This is the framework from the Norwegian column. Four steps, because plumbers do four things, not twelve.

1. Measure your current response time. Not what you think it is. What it is. Take the last ten enquiries and find two timestamps: the form or missed call, and your first reply. Write down the gap. The 2014 report's median was over three hours, at companies with people whose only job was replying.

2. Treat web and ad forms as a top channel, not the junk drawer. The form on your website. The Google Business message. The Checkatrade enquiry. These land in an inbox nobody watches from the van. Route them to the same phone that gets the calls. If the form goes to an email address you check at night, you've built a twelve-hour delay into your business on purpose.

3. Send a fast confirmation that sounds like a person. This is the one-to-two-minute target. The customer doesn't need the plumber in two minutes. She needs to know she's been heard, so she stops working down the list. Something like: "Hi Sarah, got your message about the leak under the sink. I'm on a job until about three and I'll ring you before four. If it's getting worse, ring me now on this number. Ivar." It's automatic, and that's fine. A generic "Thank you for your enquiry, someone will be in touch within 48 hours" is worse than nothing. It tells her to keep looking.

4. Do the personal follow-up between jobs. The confirmation buys you an hour or two. It doesn't buy you the job. Between jobs, before you start the engine: ring the ones who sent forms. Say who you are, that you got the message, ask the three questions (what, where, how urgent), and give a time. For quotes that don't close on that call, I've written up a follow-up sequence for electricians that works the same for plumbers, including the texting rules for the US and the UK.

Steps one and three are the ones most plumbers skip, and they're the cheapest.

Where the phone fits, and what AI cannot do

Everything above is about the form. The phone is the same problem at higher speed, and it's the one I build for.

Here's the honest version of what mine does. It answers on the first ring. It finds out what the job is, where it is, and how urgent. Then it texts you and gets out of the way. It does not book. It does not promise a time. It does not dispatch. You ring back in a few minutes and close it yourself, from your head, the way you always have. The details are on the receptionist page, and the plumbing setup is on the plumbers page.

What AI cannot do here is the part the vendors skip. It cannot decide whether you want the job. It cannot price it: a call-out fee is yours to set, and a bathroom quote needs a site visit. It cannot diagnose. It can ask "is the water still running" and pass on the answer. It cannot tell a weeping compression fitting from a split pipe, and it must not try. I'd rather it said "the plumber will ring you back" a hundred times than guessed once.

In Housecall Pro's October 2025 survey of 1,040 US homeowners, 53% said they're comfortable with AI handling the initial enquiry. A majority, not everyone. That's why every build I ship keeps a fallback route to the voicemail or answering service you already have. The job is won when you ring back, not when the machine picks up.

When not to buy any of it: if your phone rings a handful of times a day and you answer it, and your forms get a reply inside the hour, you don't have a speed-to-lead problem. Keep your money and do step one anyway.

Do this this week: time five enquiries

Don't buy anything. Measure first.

Take the next five enquiries that come in, however they arrive: form, Checkatrade message, missed call, text. For each one, write down two times. When it arrived, and when the customer first heard back from a human. Not the auto-reply, if you have one. You.

Then write the gap next to each one. Five lines on a piece of paper.

If every gap is under an hour, you're ahead of most of the companies in the studies above, and your problem, if you have one, is somewhere else. If the gaps are measured in half-days, you've found the leak, and you found it for free. Put your enquiry count and your average job into the calculator and see what a faster reply is worth to you.

And if you want a second pair of eyes on those five lines, book a growth call. Thirty minutes, free, and I'll tell you if the answer is to change nothing.
