The short answer: yes, speed still wins the job, but the number everyone quotes to prove it is not new research. The claim that calling a lead back within 60 seconds lifts sales by 391% comes from a real study, not a made-up statistic, and that study is from 2010. What has not changed in fifteen years is the plain mechanic underneath it: whoever answers first usually gets the work. We build voice agents that answer every call, so we looked into where the number actually comes from, what current UK missed-call data says, and what fixing it costs.
Key takeaways
- The "391% more sales" figure traces back to a 2010 study by Leads360 (later InsideSales.com) of internet-generated mortgage and insurance leads in the US, not a fresh 2026 finding.
- A reasonable average for missed calls across UK sectors sits around 25%, and a 2017 survey of 300 UK micro-businesses, mostly tradespeople, found a third of incoming calls went unanswered.
- We do not promise you 391% more sales. What we put in writing before launch is simpler: every call answered, and new enquiries called back within seconds, day or night.
- A Voice Agent costs £299 to set up, then £149 to £399 a month depending on call volume. Add a UK-based human team behind it from £500 a month if your book is full enough to need one.
Where does the 391% number actually come from?
The figure gets repeated constantly in sales training, including in Alex Hormozi's speed-to-lead material, but it did not start there. It traces to a Leads360 whitepaper called "Speed-To-Call", a lead-management vendor that later became InsideSales.com. The whitepaper found that responding to a lead within one minute produced a 391% improvement in conversion, dropping to 62% within 30 minutes and 36% within an hour, drawn from several million internet-generated leads. An insurance industry trade press write-up from April 2010 already describes the study as "recently published," which dates the original research to 2009 or early 2010.
None of that makes the number false. It means it was measuring US insurance and mortgage leads bought and sold on the internet during a specific period, not UK tradespeople, clinics or salons in 2026. A number that old, from a different market and a vendor with a product to sell, is not something we would repeat to you as a live statistic. It is worth knowing where it came from before anyone quotes it at you as current research.
Does the underlying idea still hold up?
Yes, and you do not need a fifteen-year-old percentage to see why. When someone rings around for a quote, whether that is a boiler repair, a valuation or a consultation, they are often calling more than one business in the same afternoon. The business that picks up, or calls back first, gets first go at winning the job before the caller moves to the next name on their list. People book tradespeople and services from whoever they can actually reach, and that needs no statistic.
What we will not do is promise you a specific uplift number for your business, 391% or otherwise. Call volume, trade and local competition all change the outcome too much for any single figure to mean anything. What we can control, and what we build, is the response time itself.
What are UK businesses actually missing right now?
For current, UK-specific numbers, the clearest published rundown is from Paperclip's analysis of missed business calls, which pulls together the available surveys since no single body tracks this centrally in the UK. It puts a reasonable average for missed calls across all sectors at around 25%. A 2017 survey of 300 UK micro-businesses, mainly tradespeople, found a third (33%) of incoming calls went unanswered. A 2016 survey of 10,000 UK businesses, including larger companies with dedicated reception, found a lower rate of 22%, which suggests the smallest businesses carry more of the problem. The same write-up cites other research finding that most callers, 85%, do not try a second time if their first call goes unanswered. They call the next business instead.
Put plainly: if your business misses a quarter of its calls, and most of those callers do not ring back, that is a quarter of your enquiries going to whoever they tried next.
What do we do about it, and what does it cost?
Our Voice Agent answers every call, checks your actual diary and books the slot on the spot, day or night. New enquiries from your website or ad forms get called back within seconds of landing, not at the end of the day when someone gets a free minute.
| What you get | Price |
|---|---|
| Voice Agent (setup) | £299 |
| Voice Agent (monthly, by call volume) | £149 to £399 a month |
| Voice Agent + UK human team (monthly) | From £500 a month |
Your exact monthly figure is fixed in writing before launch, based on your real call volume, not a guess. Every other price we charge is on the pricing page. If you are deciding between a person and an AI on the phone, see AI receptionist vs human receptionist.
Why pair it with follow-up that never goes cold?
Answering the phone stops the leak at the call itself. The other place enquiries die is afterwards, in a form submission nobody replies to for six hours, or a quote that never gets chased. Missed-call text-back comes with Starter, and our funnels and follow-up work wires automatic follow-up sequences into the same system, so a lead that cannot be reached by voice still hears from you within minutes by text or email. If an AI agent is doing the answering, keep what it says tied to your real prices and policies: the Air Canada chatbot ruling shows what happens when it is not.
Common questions
Does a voice agent replace my receptionist?
Not necessarily. For most local businesses it replaces voicemail and missed calls outside opening hours, and handles the routine bookings so your team is not stepping out of a job to answer the phone. For call-heavy trades, clinics with a full book or anyone who wants judgement calls handled by a person, we pair it with a UK human team behind it.
What happens with a genuinely complicated call?
It gets handed to you or your team. The agent is built on your business, your prices and your diary, not a generic script, and it is set up to recognise when a call needs a person rather than guess at an answer.
How fast can this go live?
Setup is £299 and typically takes one to two weeks, since the agent has to be built around your actual services, prices and diary before it goes live, not a template.
Can I see how my current site and setup stack up first?
Yes, for free. The 48-check scan covers the technical and structural basics of your website in an instant report, before you spend anything on a fix.
What your missed calls cost you.
£780 a month
£180 a week, £9,360 a year, going to whoever answers first.
As an example from these numbers, £631 a month is left over after the receptionist’s £149 starting price. Illustrative only, not a promise of earnings.
These are example numbers. Change them to your own. Worked out as 5 missed calls a week, times £120, times the 30% who would have booked, then over a month (52 weeks divided by 12).
A receptionist that answers every call in seconds, day or night, is £149 to £399 a month. It has to pay for itself in the first month, or you get every penny back, setup included.

Want the version of this with your name on it?
Run the free scan on your current site, 48 checks including AI search, no charge, or ask for your free website: we build it first, then the systems that get you booked. £39 a month keeps us working on it to bring you more customers. It starts the month your site goes live, and if you’re not busier after three months, you get every penny back. There is no obligation either way.
