Speed to lead, for a Surrey trade, means this: the customer who searches "plumber Woking" at 7.40pm rings the first number, and if it is not answered within about five minutes of them starting to look, they have rung the second. The five-minute window is not a statistic from a report. It is how long it takes a person with a problem to find and dial the next name on the map. The money is the call-out you did not get, multiplied by every week of the year.
The five-minute window, as a mechanism
Here is how the owner describes it. You are under a boiler in Weybridge. The phone goes. You let it ring. At 5.30 you ring back and the number is engaged, or the person says "sorry mate, someone's already on their way". That is the whole mechanism. Nobody waits for a tradesperson to ring back when the water is coming through the ceiling. They open Google again, tap the next listing, and the next one answers.
Why five minutes and not thirty? Because that is roughly how long the search-and-dial loop takes. Open Maps, read three listings, tap one, let it ring out, tap the next. By the time you ring back from the van, the loop has completed at least once and often twice. For a non-urgent job, a new bathroom or a rewire quote, the window is longer, but the customer is still ringing two or three firms that evening and the first to answer sets the tone. Speed to lead is the practice of answering, or at least responding, inside that loop rather than after it.
What it costs, in your money
Worked example, with figures you should replace with your own. A plumber working Walton-on-Thames, Weybridge and Shepperton misses ten calls a week. Six of those callers ring the next plumber rather than wait. A call-out is worth between £80 and £150, verified figures for this trade; take the middle at £120.
10 missed x 0.6 lost x £120 x 52 weeks = £37,440 a year
For a roofer the arithmetic is the same shape and the stakes are higher. A new roof averages £8,000 (verified, range £4,000 to £19,000). Miss two roof enquiries a month, lose one of them to the firm that answered, and that is £8,000 of work each month that you quoted for in your head and never saw.
1 lost roof enquiry x £8,000 x 12 months = £96,000 a year
The inputs are examples. Your missed-call count and your lost share are things to measure this week, not assume. What the examples show is why the loss is invisible: it is not an invoice you can see, it is a job that went to someone else, and the only place it appears is in the missed-call log you have not been reading.
What the data says: the customers are there every month
This is the part most speed-to-lead articles skip. The reason the five-minute window matters in north Surrey is that the searches are large and they happen every month, which means the missed calls are not a bad week, they are a steady leak.
| Search term | Searches a month (UK, 2026 run-rate) |
|---|---|
| plumber woking | 508 |
| plumber kingston | 448 |
| plumber surrey | 420 |
| electrician woking | 359 |
| plumber twickenham | 335 |
| electrician surrey | 334 |
| plumber hounslow | 304 |
| plumber surbiton | 216 |
| electrician twickenham | 180 |
| plumber teddington | 159 |
| plumber weybridge | 144 |
| plumber feltham | 140 |
| plumber walton on thames | 129 |
| plumber staines | 115 |
| electrician kingston | 114 |
| electrician weybridge | 91 |
| plumber addlestone | 90 |
| plumber cobham | 81 |
| plumber egham | 80 |
| electrician walton on thames | 76 |
| plumber chertsey | 69 |
All figures checked 13 October 2026. Read them the practical way. Across Woking, Kingston, Twickenham and the county term alone, more than 1,700 people a month type "plumber" plus a place name. Each search that becomes a call goes to the listing that answers. If your firm is one of the three the customer tries and you are the one who rings out, the 508 searches in Woking are being converted by someone else. Nobody searches "speed to lead Woking"; the term "speed to lead" gets 70 searches a month across the whole UK, and "lead response time" gets 21. The owners who need this are not searching for it. They are searching their own call log, if they are lucky.
Your three options for closing the window
Option 1: Answer more calls yourself
What it means. A Bluetooth earpiece, a rule to stop and answer between 8am and 6pm, and a missed-call text that fires when you cannot.
How you know it works. Your answered-call rate goes up and you can see it in the log within a week. A customer who hears a real tradesperson say "I'm on a job in Chertsey, I can be with you at 4" is the best possible outcome.
Where it falls down. You are in a loft, under a floor, or driving. Stopping to answer costs you time on the job you are on, and the customer in front of you notices. It covers nothing after 6pm or at weekends, which is when a large share of emergency calls arrive. And it depends on your discipline on your worst day, which is exactly when the phone is busiest. Our speed to lead guide for trade owners walks through timing your own responses first, which is where everyone should start.
Right for. A sole trader with fewer than ten missed calls a week, working daylight hours, who will genuinely stop for the phone. Do this and measure before spending a penny.
Option 2: Put a person on the phone
What it means. A partner at home, an office administrator, or a human answering service that takes a message and texts it to you. The phone is answered by a person inside the window.
How you know it works. Missed calls drop to near zero in the hours the person is there, and you can measure callback times. For a firm with three vans and an office, this is how it has always worked.
Where it falls down. A message is not a booking. The customer with a leak hears "he'll call you back" and keeps the next number in their other hand. A person costs the same whether the phone rings or not, and the hours when calls are most urgent, evenings and weekends, are the hours a person is least willing to cover. An outsourced service charges per call, so the busy week after a cold snap is also the expensive one, and the agent cannot say whether you cover Cobham or what a call-out costs.
Right for. A firm with an office already, or a partner who wants the role, where most calls are quotes rather than emergencies and a message with a callback inside 30 minutes is enough.
Option 3: Answered and booked, every hour
What it means. An AI receptionist: software that picks up on the first ring, any hour, in a natural voice, asks what you have told it to ask (postcode, what is wrong, how urgent, is water or power involved), checks it against the areas and jobs you do, offers a real slot from your diary and books it, then texts you the summary. The customer ends the call with a time, not a promise. It is the Speed to Lead system we run at Bad Boy Labs, and the trades page shows how it is set up for a van-based firm.
How you know it works. The mechanism is that there is no voicemail moment, so there is no point at which the customer decides to ring the next name, and the booking closes the loop. Ring one with your worst call, a burst pipe in a postcode on the edge of your patch, and listen to whether it books or bluffs. For emergency work the detail matters; see emergency call-outs: speed to answer.
Where it falls down. It only knows what you wrote down. A lazy briefing books jobs you do not do in places you do not go. It needs a diary it can read, which for a lot of trades means moving from a paper diary or a head to a calendar on the phone. And for a sole trader with five missed calls a week it is more than you need.
Right for. A firm missing more than ten calls a week, with same-day or emergency work, where the sum above is a number you would notice, and where evenings and weekends are where the calls go unanswered.
| Answer it yourself | A person on the phone | Answered and booked | |
|---|---|---|---|
| Inside the five-minute window | When you can stop | In their hours | Always |
| Evenings and weekends | Rarely | Rarely | Yes |
| Job booked on the call | Yes, if you stop | No, a message | Yes |
| Cost moves with call volume | Your time | Per call, if outsourced | Depends on contract |
| Knows your patch and prices | Yes | Only if in-house | Only what you wrote down |
Our recommendation
Bottom line: count your missed calls for one week first. Under ten, answer them yourself and switch on a missed-call text. Over ten, with emergency or same-day work, put an AI receptionist on the line so every call is answered and booked inside the window, including at 7.40pm.
The reason is the shape of the loss. In the worked example the £37,440 is six lost calls a week, every week, and most of them land when you are on a job or after hours. Option 1 recovers the ones you can stop for. Option 2 recovers the ones in office hours, as messages. Option 3 is the only one that closes the window at the hours the leak is worst, and it closes it with a booking. If your count comes back at four missed calls a week, the honest answer is an earpiece and a text, and you should not pay anyone for anything else.
How to do it this week
- Monday: pull the log. On your mobile, open Recents and scroll back seven days. Write down every missed inbound call with the time. On a hosted system it is under Reports, then Call History, filtered to unanswered. Done looks like a list with a time against every missed call.
- Tuesday: ring them back and ask. "Did you get sorted?" Mark each one: got the job, lost to another firm, not a job. Done looks like a count of lost calls in a week; that count is the only number this article is about.
- Wednesday: do the sum. Lost calls x your average call-out (use your last 20 invoices divided by 20) x 52. Done looks like one annual figure you can say out loud.
- Thursday: write the one-page briefing. Postcodes you cover, jobs you do and do not, your call-out price range, your hours, what counts as an emergency, and what to ask every caller. This page is useful whichever option you choose. Done looks like a sheet your partner, an answering service or software could follow word for word.
- Friday: switch on the floor. Set a missed-call text in your phone system (Call Handling or Call Flows, "missed call SMS") with your name, where you are, and a callback time you will keep. Done looks like a text arriving on a second phone 30 seconds after you let your business number ring out.
- Next week: test the ceiling. Ring a live AI receptionist with your Thursday briefing in front of you and your hardest call. Done looks like a booking offered for a real slot and nothing said you would not say yourself.
Mistakes we see
- Assuming the missed-call count instead of reading the log. Every owner guesses low. The Recents list does not.
- Counting answered calls instead of booked jobs. A message taken is not a job. Measure bookings from calls that used to be missed.
- Fixing office hours and ignoring 7pm. The window is worst after 6. Cover the hours the log shows, not the hours you are awake.
- A paper diary. Nothing can book into a notebook in the van. Move the diary to your phone before anything else.
- Letting the receptionist, human or software, guess your patch. Write the postcodes down. "Surrey" is not a patch.
Want your week of missed calls costed?
Send me a screenshot of your Recents list for the last seven days and your last 20 invoices' total. I will tell you how many calls you lost, what they cost at your call-out value, and whether an earpiece and a text is enough or whether answered calls would pay for themselves. If the count says you are fine, I will say so. Want me to map where your calls are leaking, yes or no? The answered-calls option is on the AI receptionist page.
