What does an AI receptionist cost in the UK?

Most off-the-shelf AI receptionist tools charge a monthly subscription, usually priced by call volume or minutes, and prices change often enough that any number printed here would go stale. The better comparison is against what a missed call costs you: one lost job a month usually pays for the tool several times over. A custom-built option costs more up front but answers with your prices, your services and your booking system.

Will customers mind talking to an AI?

Customers mind silence more. A clear, honest AI that answers immediately, says what it can help with and hands anything complicated to a human beats a phone that rings out. Problems come when an AI pretends to be a person or bluffs answers it does not know. Set it up to be honest and to escalate.

Do I need an AI receptionist or just missed-call text-back?

If most callers ask the same few questions, missed-call text-back plus a good website answers most of them for a fraction of the cost. An AI receptionist earns its keep when call volume is high, calls come outside opening hours, or callers need to book while they are on the phone.

AI receptionists for UK small businesses

Every call that rings out while you are on a job is a coin toss on whether the caller tries again or phones the next name on the list. AI receptionists exist to stop that. Here is what they can do, what they cost, and how to tell whether you need one at all.

What an AI receptionist actually does

An AI receptionist answers your business phone with a natural-sounding voice, around the clock. Depending on the setup, it can:

Answer the questions most callers ask: prices, opening hours, whether you cover their area
Take a message and send it to you instantly, with the caller's details already captured
Book appointments directly into your calendar or booking system
Recognise an emergency or a complex query and put it through to a human
Text back any call it could not handle, so the caller is never left in silence

The good ones are honest about being automated, and hand over gracefully when a call needs judgement. The bad ones bluff. When you trial any provider, ring it yourself and ask something off-script; how it fails tells you more than the demo.

Your three options, honestly compared

1. Missed-call text-back

The cheapest fix. It does not answer the phone; it instantly texts anyone you miss, so the caller knows you exist and are coming back to them. If your call volume is modest and most questions are simple, this plus a decent website solves most of the problem for a fraction of the cost.

2. Off-the-shelf AI receptionist

Subscription tools, typically priced by call volume or minutes. Quick to set up and easy to leave, which is a genuine advantage. The limitation is that they know what you teach them through a form, so answers stay fairly generic unless you invest time in the setup.

3. A custom build

Built around your actual business: your price list, your services, your booking system, your rules about what gets escalated. Costs more up front, does exactly your job, and there is no monthly platform fee inflating over time. This is the kind we build; automations start from £500 with a £99 workflow audit first, credited against the build.

What it costs, and the sum that matters

Subscription prices change too often for a printed number to stay honest, so do the sum that does not change. Work out what one lost job is worth to you, then estimate how many calls you miss in a month. For most trades and clinics, recovering one or two lost enquiries a month pays for any of the three options above. If it does not, you probably do not miss enough calls to need one, and that is a fine answer too.

Questions to ask any provider

What happens when it does not know the answer? (The only acceptable answer involves a human.)
Can it book into the calendar or booking system I already use?
Can I read every conversation it has had on my behalf?
What is the notice period? Monthly rolling is the honest default.
Does it tell callers it is automated? It should.

Where to start

Count your missed calls for one week; your phone's call log already has the data. If the number surprises you, the wider fix is in our guide to never missing another enquiry, and if you want it looked at properly, the free 30-minute audit covers how enquiries reach you and where they leak.
