Is an AI receptionist worth it? A worked example for UK small businesses

If you search for this question, you mostly find two kinds of answer. Companies selling AI receptionists tell you it's a no-brainer, and forum threads argue about it without anyone doing the maths. Neither helps you decide whether it's worth £99 a month for your business.

So this guide does the sum. It walks through one worked example for a small trade business, shows you how to run the same numbers for yourself, and is honest about the businesses that shouldn't bother. We sell an AI receptionist, so you're entitled to be sceptical. The figures below are examples, clearly labelled, and you can swap in your own.

What you're actually paying for

An AI receptionist answers your business number when you can't. For most small businesses, that isn't one big gap in the day. It's dozens of small ones: you're under a sink, on a roof, driving between jobs, with a customer, or it's 7pm and you've finally sat down for tea.

When it answers, it should do the job a good receptionist would. It greets the caller in your business's name, finds out what they need, takes their details and checks them back, answers the common questions about your services, prices and area, and sends you a summary straight away so you can call back the ones that matter. If something is urgent, it can transfer the call to a person.

With ARROW, that's a fully managed service. We build it, train it on your business and test it, and it answers 24/7, including evenings, weekends and bank holidays, at no extra cost. Plans start from £99 a month including 150 minutes, with no contract. You can see the full pricing here. If you want to compare what other UK providers charge, our guide to what AI receptionists really cost sets out the published prices side by side.

So the real question isn't "what does it cost?". It's "what are the calls I'm missing worth?"

The sum: missed calls, real jobs and what they're worth

You only need three numbers to work out whether an AI receptionist pays for itself:

1. How many calls you miss in a typical week. Your phone's call log will tell you. Count the calls you didn't answer and didn't manage to return in time.
2. How many of those were new work. Not every missed call is a job. Some are suppliers, existing customers, sales calls or wrong numbers. Be honest about the share that were real enquiries you'd probably have won if you'd picked up.
3. What a typical job is worth to you. Use the profit you keep, not the invoice total, because that's the fair comparison with a monthly fee.

Multiply the first two to get the jobs you're losing each month, multiply by what a job is worth, and compare that with the monthly cost. If you'd rather not do it on paper, our missed call calculator runs the same sum for you.

A worked example: a one-van plumber

Here's the sum for an imaginary one-person plumbing business. These are example figures to show how the sum works, not averages or survey data. Your own numbers will be different, and that's the point.

In this example, the plumber is about £225 a month better off, even after counting only profit and assuming four out of five missed calls were never going to be work. The break-even point is much lower than that. If a typical job leaves you £75 of profit, you need just two extra jobs a month to cover £99. If your jobs are bigger, one is enough.

Now the same sum for a much quieter business, again using example figures:

On those numbers, an AI receptionist doesn't pay for itself in won jobs alone. It might still be worth it to you for other reasons, such as not being interrupted on jobs or covering a holiday, but you'd be paying for peace of mind rather than profit. That's a perfectly fair choice, as long as you make it knowingly.

What about paying someone to answer the phone?

The other obvious option is a person. If you employ someone to answer the phone, the legal minimum for a worker aged 21 or over is the National Living Wage, which is £12.71 an hour from April 2026 (gov.uk, checked November 2026).

As a simple example, someone covering the phone from 9am to 5pm, five days a week, is 40 hours. At £12.71 an hour, that's £508.40 a week, or roughly £2,200 a month, before employer National Insurance, pension contributions and holiday cover. And it only covers those 40 hours. Evenings, weekends and lunch breaks are still unanswered.

A good receptionist does far more than answer the phone, of course. If you need someone to run the diary, greet visitors and chase invoices, that's a different job. But if the problem is simply "calls go unanswered while I'm working", paying a full wage to solve it is usually the most expensive option. Shared human answering services sit in between, usually charging per call or per minute. Our guide to UK telephone answering services compares their published prices.

When an AI receptionist isn't worth it

This is the section most providers leave out. An AI receptionist probably isn't worth it for you if:

• Your phone rarely rings. If you get a handful of calls a week and miss almost none, the second example above is you. Save your money.
• Someone already answers every call. If you have a receptionist, a partner in the office or a team that genuinely picks up every time, an AI receptionist adds little during the day. It may still be worth it for evenings and weekends, which our guide to 24/7 call answering covers.
• Most of your calls need you, specifically. Some businesses live on calls where the customer wants one named person's judgement there and then. An AI receptionist can take the details and pass the call on, but it won't replace that conversation.
• Your customers mostly email or book online. If the phone is a small part of how work arrives, fix the channel that matters first.

In our experience, the businesses that get least from an AI receptionist are the ones with very low call volumes.

What if you take twenty calls a day or more?

Busy lines are where an AI receptionist tends to earn its keep, because the more calls you take, the more you miss when you're tied up. It can take several calls at once, so a busy spell doesn't mean engaged tones or a queue.

A busier line does use more minutes. ARROW's starter plan includes 150 minutes a month, and busier lines move up a plan, so check the pricing page for the plan that fits your call volume. Run the sum above with your real figures. At twenty calls a day, even a small share of missed new work usually adds up quickly.

How to test it without taking a big risk

You don't need to take anyone's word for this, including ours. Three ways to keep the risk small:

1. Hear it first. Ring our demo AI receptionist, Bow, on 0208 264 9834 and try to catch her out. Ask what you'd ask as a customer.

   Calls are recorded and transcribed, and we may follow up about your enquiry. See our Privacy Policy.

2. No contract. ARROW plans are monthly, so if it isn't paying its way, you stop.

3. Our guarantee. "Book four real jobs in 30 days using our tools, or get your money back."

Setting it up starts with a 20-minute onboarding call. We build and test your AI receptionist, you divert your existing number to it, and you're live within 3 to 7 days. You can read more about how ARROW works, or, if you're new to all this, start with our plain-English guide to what an AI receptionist is and how it works.

The bottom line

An AI receptionist isn't worth it for everyone, and anyone who says otherwise is selling something. It's worth it when the calls you miss are costing you more than it costs, and for most busy small businesses that bar is low: one or two extra jobs a month. Do the sum with your own numbers. If it comes out in your favour, have a look at the pricing and give Bow a ring on 0208 264 9834.
