Call Handling
Answering Service vs Voicemail, AI and Hiring
Quick Summary
You have five realistic options when your phone goes unanswered: voicemail, diverting to your mobile, an AI receptionist, a human answering service, or hiring someone. Each suits a different business, and the cheapest one is rarely the right one.
- Voicemail and mobile diverts cost nothing, but both lose calls in ways most owners never see
- 83% of UK consumers would rather speak to a real person, and only 4% prefer an automated voice (8×8 research, October 2025)
- But about one in three said they would accept AI if it meant lower prices, so the picture is not one-sided
- AI receptionists run £30 to £299 a month. Human services ran from £49 to £400. Hiring costs about £29,000 a year.
What are your five options?
Voicemail fails because most callers will not use it. Around 17% leave a message when they reach an answer phone. The rest hang up, and a large share of those rings the next company on their list within minutes.
Think about the last time you rang a business and got a recorded message. Did you leave your name and number and wait? Most people do not.
There is a second problem that is easier to solve. Voicemail tells you that you missed a call, but it does not tell you what the caller wanted. You ring back the next morning with no idea whether it was a new customer, a supplier, or somebody selling insurance.
One thing voicemail does do well is act as a record. If you are choosing between voicemail and literally nothing, keep it. Just do not treat it as cover.
Should you just divert calls to your mobile?
Diverting calls to your mobile works for very small businesses with low call volumes. It stops working the moment you are on a job, driving, in a meeting, or already on another call, which for most trades is most of the day.
It costs nothing, which is why most people start here. Four things go wrong.
- You answer badly. Picking up in a noisy van with no pen is worse than not picking up at all. Callers hear it.
- You only get one at a time. A second caller during the first call gets your voicemail anyway.
- It follows your home. Evenings, weekends and holidays stop being yours. This is the cost nobody puts in the spreadsheet, and it is the one that eventually makes people stop.
- Nothing gets written down. You can get a job on the phone at 7pm and forget it by Monday.
If you take under five calls a day and work mostly at a desk, diverting is fine. Be honest about whether that describes you.
Is an AI receptionist good enough now?
AI receptionists have improved a lot and now handle simple, predictable calls well. They struggle with unusual requests, strong accents, emotional callers and anything needing judgement. UK customers also still prefer a person, though not by as much as the industry claims.
This is the option that has changed most in the past year, so it deserves a fair hearing.
What AI does genuinely well:
- Answers instantly, every time, at 3am on a Sunday
- Handles twenty calls at once without a queue
- Costs a flat monthly fee with no per-call surprises
- Takes basic details and books simple appointments without complaints
Where it still falls:
- Callers who go off script, change their mind mid-sentence, or explain things out of order
- Emergencies, where the caller is stressed and needs reassurance as much as information
- Anything requiring a judgement call about whether something is urgent
On the research, be careful. Survey after survey shows UK customers prefer a human voice, and the numbers are real enough. But most of these surveys are paid for by answering service companies, who sell the human option. The most useful finding is the one they quote least: roughly a third of people said they would accept AI if it meant lower prices. Customers are not against automation. They are against being trapped in it.
Our honest reading is this. If your calls are short, routine and like each other, AI will probably do the job for less money. If your callers are worried, or the enquiry is worth thousands, a person still wins.

When does a human answering service make sense?
A human answering service makes sense when your calls are valuable, urgent or unpredictable, and when getting one wrong cost you more than the monthly fee. That covers most trades, clinics, law firms and letting agents.
The test is simple. Ask what your average enquiry is worth.
If a typical new customer brings in £150, a £200 monthly service needs to save you about two jobs a year to break even, which is easy. If a typical customer is worth £15 and you take four calls a week, the math’s does not work, and you should not buy it.
The other case for a person is judgement. Someone ringing about a leak at 11pm needs an agent who can tell the difference between a dripping tap and water coming through a ceiling. That decision is not really about scripts.

When should you just hire someone?
Hiring makes sense when your call volume is steady all day, when you need someone in the building for post and visitors, or when the work needs deep knowledge of your business that no outside team will pick up.
We would rather say this plainly than have you find out in six months.
An answering service covers the phone. A receptionist covers the phone, the door, the post, the diary, the filing and the hundred small things that come up when someone is physically there. If you need those, no phone service replaces them.
The catch is coverage. A full-time receptionist covers 40 hours of a 168-hour week, and none of your evenings or weekends. Plenty of businesses end up doing both: a receptionist during the day, an answering service for everything else.
What does each option cost?
Voicemail and mobile diverts are free. AI receptionists run about £30 to £299 a month. Human answering services run about £49 to £400 for business hours, rising to £300 or more for genuine 24/7 cover. Hiring costs around £29,000 a year.
Option | Typical UK cost | Best suited to |
Voicemail | Free | Nobody, as your only cover |
Divert to mobile | Free | Under five calls a day, desk-based work |
AI receptionist | £30–£299 a month | High volume, short and routine calls |
Human answering service | £49–£400 a month | Valuable or urgent enquiries |
24/7 human cover | £300–£500+ a month | Emergency trades, out-of-hours work |
Hiring a receptionist | About £29,000 a year | Steady daytime volume plus office duties |
Two warnings about these numbers.
First, the headline price is rarely the bill. Ask how calls are counted, whether wrong numbers are charged, what happens when you go over your allowance, and whether bank holidays cost extra. Overage charges of £0.50 to £2.00 per call are common and they add up in a busy month.
Second, out-of-hours cover is usually priced separately. A service quoted at £150 a month for business hours can cost three times that once evenings and weekends are added. Ask for the full figure before you compare anything.
Which one is right for your business?
Match the option to your actual problem rather than your budget. Most businesses buy on price, discover it does not fit, and switch within a year, which costs more than choosing properly the first time.
Your situation | Best option | Why |
Under 5 calls a day, desk-based | Divert to mobile | You can genuinely answer them |
High volume, short routine calls | AI receptionist | Costs per call drops sharply |
Emergency or urgent work | Human, 24/7 | Judgement matters more than speed |
High-value enquiries | Human answering service | One saved job pays for months |
Steady all-day volume plus office work | Hire someone | You need a person in the building |
Busy days, quiet evenings | Hire plus a service | Cover the gap, not the whole week |
If you sit between two rows, start with the cheaper one and give it three months. Moving up later is easy. Getting out of a twelve-month contract you picked in a hurry is not.
Frequently asked questions
1. Is an answering service better than voicemail?
For most businesses, yes. Only about 17% of callers leave a voicemail message, so the rest are lost without a trace. An answering service captures the enquiry and tells you what the caller wanted, which voicemail never does.
2. Can an AI receptionist replace a human answering service?
For simple, repetitive calls it often can, and for less money. For urgent, emotional or high-value enquiries a person still handles the call better. Many businesses now use AI for overflow and keep humans for out-of-hours emergencies.
3. How much does 24/7 phone cost in the UK?
Genuine round-the-clock human cover usually costs £300 to £500 a month or more, depending on call volume. Business-hours-only packages start much lower, around £49 to £150, so always check which one a quoted price refers to.
4. Will customers know they are talking to an answering service?
With human service, usually not. Agents answer in your company name using your greeting. With AI, most callers work it out within a sentence or two, which matters more in some industries than others.
5. Can I use an answering service only for evenings and weekends?

5. Can I use an answering service only for evenings and weekends?
Yes, and this is one of the most sensible ways to buy. You keep answering your own calls during the day and pay only for the hours you cannot cover, which usually cost far less than a full package.
Conclusion
There is no single right answer here, and any company telling you otherwise is selling something. Voicemail suits nobody as a main plan. Mobile diverts suit quiet, desk-based businesses. AI suits high volumes of simple calls. People suit urgent and valuable ones. Hiring suits steady daytime work with office duties attached.
Work out two numbers before you decide anything. How many calls do you miss in a normal week, and what is one new customer worth to you? Those two figures will point at one row of the table above, and it may well not be ours.
