Key takeaways
- A good greeting is under 25 seconds and does three jobs: confirms who you are, says when you will call back and asks for the details you need.
- Heating and electrical greetings should carry the right emergency number for gas leaks and power cuts.
- Ask for name, postcode, the problem in a sentence and the best time to call; that is enough to call back ready to help.
- Keep separate greetings for working hours, evenings and holidays, and change them on the day.
Why the greeting matters more than you think
Most small trade firms are run by the person doing the work. An estimated 74% of UK private sector businesses have no employees besides the owners[1]. That means a large share of customer calls will reach voicemail at some point, and the greeting becomes your receptionist.
Callers decide in a few seconds whether to leave a message or try the next firm. A default network greeting reading out your number tells them nothing. A short, confident greeting tells them they have reached a real business that will ring back.
What every greeting needs
- Your business name, said clearly at the start, so callers know they have the right number.
- A reason you cannot answer that sounds like work, not avoidance: on a job, up a roof, with a customer.
- A callback promise you can keep, such as within the hour or by the end of the day.
- The details you want left, in the order you want them.
- Any emergency number relevant to your trade, said slowly.
Leave out long lists of services, website addresses spelt out letter by letter and recorded music. Keep it under about 25 seconds; callers stop listening after that.
Five scripts you can record today
Each script below is an example for a fictional business. Change the name, the callback time and the trade details, then read it aloud a few times before recording.
Heating engineer. Example: Hello, you have reached Hartley Heating. I am on a job at the moment. Please leave your name, postcode and what is happening with your boiler or heating, and I will call you back within the hour. If you smell gas, hang up now and call the free National Gas Helpline on 0800 111 999.
The gas line is free and open 24 hours a day[2]. Putting it in your greeting is a simple safety step that also shows callers you take gas seriously. Mention that you are Gas Safe registered if you are; landlords know their annual gas safety checks must be done by a registered engineer[3].
Electrician. Example: Hi, this is Morgan Electrical. I am working on site and cannot take your call. Leave your name, postcode and what the problem is, for example tripping, no power or a quote, and I will ring you back today. For a power cut affecting your street, call 105. If anything is smoking, sparking or burning, call 999.
The 105 number is a free national line that puts callers in England, Scotland and Wales through to their local electricity network operator[4]. It saves you callbacks for network faults you cannot fix. If you belong to a competent person scheme, say so: in a large NICEIC survey, 83% of respondents said it was important that their electrician was registered with one[5].

Roofer. Example: You have reached Brookside Roofing. We are up on a roof right now. If water is coming into your home, please say so at the start of your message, along with your name and postcode, and we will call you back as a priority. For quotes and inspections, leave your details and we will ring you back the same day.
Cleaner. Example: Hello, you have reached Fresh Start Cleaning. We are with a client at the moment. Please leave your name, your postcode, the type of clean you are after, such as regular, one-off or end of tenancy, and roughly how many bedrooms. We will call you back by the end of the day.
Pest control. Example: Thanks for calling Greenway Pest Control. We are on a treatment and cannot answer. Please tell us your name, postcode and the pest, for example wasps, mice or rats, and where you have seen it. We return calls within two hours during the day. If someone has been stung and is struggling to breathe, call 999.
What to ask callers to leave
| Detail | Why you need it | Trades where it matters most |
|---|---|---|
| Name | So you can greet them properly and match them to past jobs | All |
| Postcode | Tells you whether you cover the area and how to fit them into the day | All, especially mobile trades |
| The problem in a sentence | Lets you triage before calling back and bring the right parts | Heating, electrical, roofing |
| Who they are | Homeowner, tenant, landlord or agent changes who approves the work | Repairs and maintenance |
| Best time to call | Avoids rounds of missed calls in both directions | All |
Do not ask for more than five things. Callers forget long lists, and a message with a name and number but no detail is still better than a hang-up.
Recording a greeting that sounds professional
Write it down first
Read your script aloud and time it. Cut anything that pushes it past about 25 seconds.
Find a quiet spot
Sit in the parked van with the windows up, or a quiet room. Avoid echoing kitchens and windy yards.
Hold the phone normally
Speak at your usual distance from the microphone, a little slower than you would in conversation.
Smile while you speak
It sounds odd, but it changes your tone and callers can hear it.
Listen back on another phone
Ring your own number from a different phone and check the volume and clarity.
Check the emergency numbers
Say each digit separately and listen back to make sure every one is clear.
Greetings for evenings, weekends and holidays
One greeting is not enough. A callback promise of within the hour is misleading at 9pm on a Saturday. Record at least two versions and switch between them.
- Evening and weekend. Example: Thanks for calling Hartley Heating. We are closed and will call you back from 8am. If you have no heating and someone vulnerable at home, say so in your message and we will call back first thing.
- Holiday. Example: Morgan Electrical is closed until Monday the 4th. For urgent work, call our partner firm on the number we will text you after this message. For a power cut, call 105.
- Overloaded day. Example: We are very busy today and returning calls in the order they come in. Please leave your details and we will get back to you before 6pm.
If you offer out-of-hours work, the evening greeting should tell callers how to reach the on-call engineer rather than asking them to wait until morning. Our guide to emergency electrician call triage and the boiler breakdown script cover what to ask once you are speaking to the caller.
Mistakes that cost callbacks
- A full mailbox. Clear old messages daily; callers who hear the mailbox is full almost never ring again.
- A personal greeting on a business number. Callers hearing your children’s voices may assume they have the wrong number.
- Promising callbacks you cannot keep. Within the hour only works if you have a routine; see our guide on how fast to return missed calls.
- No mention of emergencies on a heating or electrical line. It is a missed chance to keep people safe.
- Long silence at the start. Trim the recording so your voice starts straight away.
Test your greeting like a customer would
Once a quarter, ring your own business number from a phone that is not in your contacts and listen as a stranger would. Ask yourself whether you would leave a message. Then check what happens next: does the message arrive as a notification, a transcript or an email, and how long does it take you to see it?
- Ring at a busy time of day and check the call reaches voicemail rather than ringing out.
- Leave a test message with a postcode and check it is clear when played back on the van speaker.
- Ask a friend or family member for honest feedback on tone and length.
- Check the greeting still matches reality: hours, callback promise, emergency numbers and any partner firm.
Many networks and business phone apps can also send an automatic text to anyone whose call you miss. Pair it with your greeting so the text says the same thing in fewer words. Callers who will not leave a voicemail will often reply to a text.
When voicemail stops being enough
Voicemail works when the volume of calls is modest and callers are patient. It struggles when many callers simply hang up rather than leave a message, or when you are on jobs where calls cannot wait. At that point the next step is a person or a service that answers live, whether a partner, an office manager or an AI Employee such as Ava, which answers with your approved greeting and takes the job details for you. Our guide to the first office hire covers when it makes sense to bring someone in.
Frequently asked questions
How long should a business voicemail greeting be?
Aim for 15 to 25 seconds. Name the business, give a reason you cannot answer, promise a callback time and ask for name, postcode and the problem.
Should a heating engineer put the gas emergency number in their greeting?
Yes. The National Gas Helpline on 0800 111 999 is free and open 24 hours a day. Telling callers to hang up and ring it if they smell gas is a simple safety step.
What number should callers use for a power cut?
In England, Scotland and Wales, 105 is a free number that connects callers to their local electricity network operator. Telling callers about it saves you callbacks for faults on the network.
