What does an AI receptionist cost against a human answering service?

An AI receptionist vs answering service cost comparison in the UK is harder than it should be, because half the market will not tell you the price. On 19 August 2026 I went through the published pages of every provider I could find. One firm aimed at trades publishes £45 a month with a £299 setup. Several of the best known human answering services publish no price at all on any page.

That gap is the most useful thing I found, so I want to start there rather than with a table.

Why can I not find a price for a human answering service?

Because they do not want you comparing before you talk to them.

I fetched the pricing pages of five well known providers in this space that day. Two of the biggest UK telephone answering companies had no figure on any page I could reach. One review platform sends its own pricing URL somewhere else entirely. One of the largest American platforms says only to talk to their sales team.

Meanwhile every provider aimed squarely at one-van trades publishes their number in plain sight.

That split is not a coincidence and it is worth understanding before you ring anybody. Firms that hide the price are selling to businesses with staff and a budget. Firms that print it are selling to somebody on their own who wants to decide in the van without a sales call. You can tell which one you are being treated as by whether the number is on the page.

What does an AI receptionist actually cost?

Verified, from providers' own published pages on 19 August 2026:

  • One UK firm aimed at trades: £45 a month, £299 setup, with 100 minutes of talk time included and 20p a minute after that. Extra messaging channels at £23 a month each.
  • A UK missed call service: £49, £129 and £249 a month by tier.
  • A large North American job management platform sells an AI receptionist as a $29 a month add-on to its software.

So the honest range for the thing itself is roughly £45 to £250 a month, and the cheap end is real rather than a teaser.

What does a human answering service cost?

I could not verify this properly and I am not going to pretend otherwise.

Comparison articles put shared human answering somewhere between £150 and £400 a month, often billed by the minute or the call. Every one of those figures came from a blog rather than from a provider, so I would not repeat them to anybody. If you want a real number you will have to ring two of them and ask, which is exactly the friction the pricing pages are designed to create.

What I can say is that a human service prices by the minute or the call, so a busy month costs more than a quiet one, and that is the opposite shape from most AI pricing, where the monthly fee is flat until you cross an included allowance.

Why does the bill change when you get busy?

This is the part nobody publishes, and it is the question that decides whether a price is fair.

Nearly every AI receptionist is built the same way underneath. A flat fee each month, a number of talk minutes included in it, and a rate for every minute after that. The flat fee is the part everybody advertises. The minutes are the part that decides what you actually pay, because a busy month is a month with more calls in it.

So the important question is not the headline price, it is what happens when you get busy. A flat fee with an included minute allowance and a stated overage rate is honest. A flat fee with no allowance mentioned is either very generous or about to change.

Ask any provider for both numbers before you sign anything. How many minutes are included, and what does a minute cost after that. If you cannot get the second one out of them, you have your answer.

So which one should a small trade actually pick?

Depends entirely on what you are trying to stop happening.

If the problem is that the phone rings out while you are up a ladder, an AI that texts the caller back within seconds solves it, and it works even if you have no website at all. That last point matters more than people realise. When we measured the trades in our own patch on 13 August 2026, the top seven electricians in Sudbury had no website on their Google listing, and five of seventeen Colchester plumbers had none either. A missed call worker needs a phone number and nothing else.

If the problem is that customers want to talk to a person about something complicated, AI is the wrong tool and a human service earns its money.

If the problem is that you cannot face another sales call, pick whoever publishes the price.

The thing I would check before signing anything

Ask what happens to the caller's number.

A missed call service only works if it knows who rang. That depends on your phone network passing the caller's details through when the call diverts, and the providers' own documentation is honest that not every carrier does. Ask them to prove it works on your network, with your handset, before you pay a setup fee.

I would not take anybody's word for that, including mine. It is a ten minute test and it is the whole thing.

Where to stop

If you take more than a handful of emergency calls a week, or you are on call overnight, the answer stops being a spreadsheet question. Ring two providers, ask what happens at three in the morning, and listen for whether they answer the question you asked.

We publish every price we charge. The AI implementation page has the detail, and what a website should cost a tradesman covers the same ground for the site itself.
