An AI receptionist for your small business: what it costs in the UK

What you're really paying for

The AI receptionist for small business UK cost question has a messy answer because three very different things hide behind the same label. Some products are a chatbot widget with a voice bolted on. Some are a phone number that reads a script. A few actually understand callers, book appointments and pass clean notes into your systems.

Price tracks capability. Before you compare numbers, get clear on what the tool has to do when a real customer rings at 7pm on a Friday.

• Answer every call, including out of hours and during busy periods
• Understand natural speech and accents, including regional ones
• Take a booking, capture a lead or qualify the caller
• Log the call into your CRM or calendar without you retyping it
• Hand off to a human cleanly when the call needs one

The cheap tier: £9 to £500 a month

Off-the-shelf AI receptionists sit roughly between £9 and £500 a month in the UK. The bottom of that range is usually a self-serve app you configure yourself. The top is a more polished call-answering product with a dashboard and a few integrations.

These tools are real and some are decent. The catch is that the price on the page is rarely the price you pay. Most charge per minute or per call on top of the subscription, so a busy month costs far more than the headline figure.

• Setup is on you: scripts, prompts, call flows and integrations
• Per-minute or per-call usage fees stack on top of the monthly plan
• Voice quality and interruption handling vary a lot at the low end
• When something breaks, you debug it yourself or wait on support

The bespoke tier: £1,500 and up

At the other end, an agency or developer builds you a custom voice agent. Budget from £1,500 to start and often a good deal more once you add the build, the integrations and ongoing changes.

Bespoke gets you exactly the behaviour you want. It also gets you a project: discovery calls, timelines, revisions and a maintenance bill. For a 10 to 100 person business that needs the phone sorted this quarter, that is a slow and expensive way in.

Why a managed voice agent beats the cheap tier

The cheap tier sells you software. A managed voice agent sells you the outcome. That gap is where most small businesses lose money, because a tool you half-configure and never tune quietly drops calls you never hear about.

A managed service handles the setup, the script, the integrations and the tuning, then keeps improving the agent as you learn what callers actually ask. You get bespoke-grade behaviour without the bespoke timeline or the per-minute anxiety.

• A human operator installs and tunes the agent inside your existing tools
• Calls land in your CRM and calendar automatically, with clean notes
• Behaviour gets refined over time as real call data comes in
• One predictable price instead of a subscription plus surprise usage fees

Where Isla fits

Isla is Hattrick's voice agent. She answers inbound calls and makes outbound ones, books into your calendar and writes every conversation back to your CRM. A human operator installs her, tunes the script to how your business actually talks and keeps her sharp as your calls change.

Isla is one of 22 agents Hattrick runs across sales, finance, customer service and brand, so the phone connects to the rest of your follow-up rather than sitting on its own island. You can see how she pairs with the other agents and add her to a plan when the timing suits.

On price, Isla is an add-on to a Hattrick plan rather than a standalone per-minute meter, so your monthly cost stays predictable as call volume moves around.
