Lead response time statistics: how fast is fast enough?

In 2011, three researchers writing in Harvard Business Review described a simple test. They sent a web inquiry to 2,241 US companies and timed the replies.

37% got back within an hour. 23% never got back at all. The ones that did reply took 42 hours on average.

Most "speed to lead" numbers you'll see quoted trace back to that study or two others like it. They're worth knowing, and worth knowing what they measured, because a plumber or an HVAC shop mostly gets leads by phone, and the phone has its own numbers.

The speed-to-lead studies everyone quotes

• Harvard Business Review, 2011. The 2,241-company test, plus a second look at 1.25 million leads at 42 companies. Firms that got back to a lead within an hour were nearly seven times as likely to qualify it as firms that waited one hour more, and more than 60 times as likely as firms that took a day or longer.
• MIT and InsideSales, 2007. Six companies, three years, more than 15,000 web leads and 100,000 call attempts. Calling within five minutes instead of thirty made a lead 100 times more likely to be reached and 21 times more likely to qualify. The authors said plainly that they didn't measure whether those leads went on to buy.
• Velocify, 2012. About 3.5 million leads. Calling inside the first minute raised conversion by 391%.

All three point the same way, and hard. Faster wins. But all three studied web forms, mostly for business-to-business sales, with data that's now 14 to 19 years old. Use them for the direction. For phone calls there's newer data, and it's closer to home.

A phone call gets answered or it's gone

A web lead can sit for five minutes. A phone call can't sit at all. Somebody picks up, or the caller hears a voicemail greeting and decides what to do next.

Most of them hang up. Moneypenny, an answering-service company, found in a 2016 UK survey that 69% of callers don't leave a voicemail. In a March 2026 survey of 2,000 US consumers, the same company found 72% were likely to choose the business that responds first. 41% expected a reply within minutes, and 17% within seconds. Bear in mind who paid for those surveys. We went through the rest in the hidden cost of voicemail.

How often home service businesses really answer

Ask owners and they'll tell you they get nearly every call. The recordings say something else.

• Service Direct, 2019. They listened to 1,000 recorded calls to 94 home service businesses. The owners guessed they answered 97%. They answered 66%. Answering services picked up 99%. 55% of the callers were new customers, and when somebody answered, they booked 63% of the time.
• Invoca, July 2026. Only 52% of callers to home service companies reached a person. And 55% of the businesses never asked the caller to book.
• CallRail, January 2025. Across 1.1 million conversations, home services missed 14% of calls. Healthcare missed 32% and legal 28%.

The three don't agree because they count different things, from a call nobody picked up to a caller who never got through to a human. Take any of them. The gap between what owners believe and what callers get is wide, and it's widest during the hours you're out working, which we covered for plumbers in business hours.

Answering is half of it

Picking up fast gets you the chance. Booking the job takes something more.

ServiceTitan's 2022 figures put the average booking rate at 42%. Shops with fewer than five technicians booked 24%. Booking ran as high as 61% at its daytime peak and fell to 21% after 6 p.m.

And remember the Invoca figure: more than half of businesses never asked the caller to book. A fast answer followed by "let me get back to you" just loses the job more slowly.

What a missed call is worth

HomeAdvisor's June 2026 cost guides put the average plumber visit at $341, an electrician at $351, an AC repair at $417 and a furnace repair at $318.

Take $340 and ServiceTitan's 42% average booking rate, and a missed call from a new customer is worth about $140 on the first job alone. That leaves out the repeat work, the referral and the property manager with forty units. Count last month's missed calls from numbers you didn't recognize, multiply by $140, and you've got a floor. There's a longer worksheet in how much missed calls are really costing you.

So how fast is fast enough?

• Phone calls: answer them live. In the first few rings, during the hours on your listing. Every study here says the same thing a different way.
• If you miss one anyway: text back right away, then call. An automatic text tells the caller you saw it and you're coming back to them. Here's how to set one up.
• Web forms and Facebook leads: call inside five minutes. These are the leads the old studies were about. Velocify also found that a text helped after the first phone conversation (conversion up 112.6%) and hurt before it (39% less likely to reach the person). Call first, text second.
• Emergencies: same day, and say so. In a 2025 FieldBoss survey, 73.8% of homeowners with an HVAC emergency expected service within 24 hours, and 29.8% within a few hours. Half of them (50.3%) preferred to call. Housecall Pro found in February 2026 that 72% would pay more to have an emergency fixed within 24 hours. The HVAC piece has more on that.

If you want one number to check this week, call your own business line at twenty to eleven on a Tuesday morning from a phone it won't recognize. Whatever happens next is what a stranger with a broken furnace gets.

Common questions

What does speed to lead mean?

It's how long a business takes to get back to someone who has just asked about its services, by phone, form or message. The shorter that gap, the more of those people you reach and book.

Is the Harvard speed-to-lead study real?

Yes. It ran in Harvard Business Review in March 2011. The authors sent a web inquiry to 2,241 US companies and found that firms replying within an hour were nearly seven times as likely to qualify the lead as firms that waited an hour longer. It studied web leads, and the data is about 15 years old.

How quickly should you respond to a lead?

Answer phone calls live. If you miss one, text right away and call back within minutes. Call web and Facebook leads inside five minutes. In every study above, the odds of reaching and booking the person drop as the minutes go by.

What's a good answer rate for a service business?

Every call during the hours on your listing. In one study of 1,000 recorded calls, owners guessed they answered 97% and actually answered 66%. Answering services picked up 99%.
