How much does an AI receptionist cost in the UK?

The three pricing models, and who each one suits

Per minute pricing looks cheapest on a quiet month. You pay for connected time, usually rounded up to the nearest minute, often with a minimum charge per call. A business taking forty short calls a month will pay very little. A business taking four hundred will not.

Per call pricing is simpler to predict and usually more expensive per interaction. It suits businesses whose calls are long, because a fifteen minute booking costs the same as a thirty second one.

Flat monthly pricing charges the same whatever the volume. It is the only model where a busy month is unambiguously good news, and it is the one we use, because a phone bill that punishes success is a strange thing to sell to somebody trying to grow.

• Per minute: from about 40p a minute, often with a one minute minimum
• Per call: from about £1.20 to £2.50 a call depending on complexity
• Flat monthly: from about £200 for a basic single line to £900 for multi site

What the real bill looks like at different volumes

Take a business receiving 300 calls a month averaging two minutes. On a 45p per minute plan that is about £270. On a £1.50 per call plan it is £450. On a flat £499 plan it is £499, and it is still £499 at 900 calls.

Now take the same business in its busiest month, when a campaign lands or the weather turns and volume triples to 900 calls. Per minute becomes roughly £810. Per call becomes £1,350. The flat fee has not moved.

This is why the comparison people run in month one so often disappoints them by month six. Averages are not what you get billed on.

How it compares with hiring somebody

A full time UK receptionist on £24,000 costs an employer roughly £28,000 to £30,000 once national insurance, pension and holiday cover are counted. That is around £2,400 a month for someone who works about a quarter of the week's hours and takes annual leave.

That comparison is not entirely fair in either direction. A receptionist greets people at the door, handles post, chases suppliers and knows your customers by name, and no software does that. But if the specific job is answering the phone reliably including evenings and weekends, one person cannot cover it and two of them cost sixty thousand.

The honest framing is not replacement. It is that the hours nobody is contracted to work are the hours a large share of your calls arrive.

The costs that are easy to miss

Setup fees are common and often four figures for enterprise style products. Ask directly, because a low monthly rate with a £1,500 onboarding charge is a different proposition to the one advertised.

Minimum contract terms matter as much as price. Twelve month lock ins are normal in this market, and they exist because switching costs suppliers customers. A one month notice period is worth paying slightly more for.

Integration charges, extra numbers, additional call handling scripts and out of hours surcharges all appear on invoices in this sector. None of them are unreasonable in themselves, but they should be on the quote rather than the first bill.

How to work out what it is worth to you

Cost is only half the question. The other half is what the calls are worth, and that is arithmetic you can do in two minutes.

Count the calls you miss in a normal week, and be honest, because most businesses guess low by half. Take a third of them as customers you would have won, since not every caller becomes a job. Multiply by what one customer is worth to you over the whole relationship, not just the first transaction.

For a trade business missing fifteen calls a week at £300 a customer, that is roughly £6,400 a month walking away. Against that, the difference between a £270 bill and a £499 bill is not the decision. Whether the phone gets answered is the decision.
