Who wrote this, and what is our interest?
SpiderHunts wrote this article. We build custom AI receptionists, so we have an interest in the answer. We do not run a human answering service and we are not paid by anyone who does. Where a human service is the better fit, we say so. Prices for other providers are described only at a general level, because they vary by plan and change often; check each provider's own pricing before you decide.
What is the difference between an AI receptionist and an answering service?
A telephone answering service is a team of trained people who answer your calls in your business name, usually from a shared call centre. They take messages, answer simple questions from notes you give them, put calls through and, on some plans, book appointments.
A virtual receptionist is a closely related idea: a remote receptionist, or a small team, who handles your calls as if they sat at your front desk. Many providers use the two terms interchangeably. Where there is a difference, a virtual receptionist usually knows more of your procedures and does more admin around the call.
An AI receptionist is software that answers the phone in natural speech. It works out what the caller wants, answers from your own approved information, books into your diary, records the details of an enquiry and passes the call or a summary to your team. We explain the technology in what conversational AI is.
The real difference is judgement versus consistency. People handle the unexpected, the upset and the delicate. Software handles the predictable, the same way every time, and can write straight into your systems.
How do the five main options compare?
Most UK businesses choose between five ways of handling the calls their own team cannot take. The charging models below are general descriptions, not quotes from any provider.
| Option | What it handles well | How it usually charges | Main limits |
|---|---|---|---|
| Voicemail | Takes a message when nobody answers | Usually included with your phone line or phone system | Many callers hang up rather than leave a message; nothing happens until someone listens |
| Human answering service | Answers in your name, takes messages, transfers calls, simple bookings | Typically a monthly plan with a call or minute allowance, or a charge per call | Receptionists answer for many businesses, so depth of knowledge is limited; extra tasks cost more |
| Virtual receptionist | Your procedures, diary management and admin around calls | Usually a monthly fee linked to hours of cover or call volume | Cover is limited to the hours you pay for; cost rises with volume |
| AI receptionist | Frequent, predictable calls, FAQs, bookings into your diary, enquiry details into your CRM | A setup fee plus a monthly fee, or a subscription per call or per minute; call minutes and AI usage on top | Not suited to complex, emotional or advice calls; needs good content and regular review |
| Hybrid | AI answers first and handles routine calls; people take the rest | A combination of the two models above | Two services to set up and pay for; handover rules must be clear |
When is a human answering service the better choice?
A human service is usually the better fit when:
- Most calls are different from each other and need judgement rather than a set answer.
- Callers are often anxious or upset, for example in care, bereavement or urgent repairs.
- Your call volume is low, so a pay-per-call plan stays modest and there is little to automate.
- Your clients expect a person and would see an AI as a step down in service.
- You do not hold your diary, prices or policies anywhere a system can read them.
There is no shame in choosing people. An AI receptionist that is forced onto the wrong calls will annoy callers and cost you more in fixes than it saves in time.
When does an AI receptionist make more sense?
An AI receptionist tends to fit when:
- A large share of calls ask the same things: prices, opening hours, availability, directions.
- Bookings need to go straight into your diary or practice software, not onto a message pad.
- Calls arrive in bursts, at lunchtime, first thing or after a marketing push, and several come in at once.
- Out-of-hours calls are worth answering but not worth paying people to cover.
- You want every enquiry recorded in the same structured way in your CRM.
It also needs the right foundations: a clear list of what it may answer, an up-to-date source of truth for prices and policies, and a quick route to a person. We cover the providers on the market in our comparison of the best AI receptionist options for UK businesses.
Why do many businesses end up with a hybrid?
Because the strengths do not overlap much. A common pattern is for the AI receptionist to answer first, handle the routine calls end to end and pass anything complex, sensitive or unclear to people, either your own team or a human answering service.
Another pattern is time-based: people answer during the day and the AI receptionist covers lunch, evenings and weekends, or only picks up when every line is busy. Either way, start with the calls where a mistake is easiest to recover from, read the call summaries for the first few weeks, and widen the AI's job only when it has earned it.
What should you ask any provider before you switch?
- Can I keep my existing number, and how are calls forwarded?
- Which calls will you handle, and what happens to the ones you cannot?
- How does a caller reach a real person, and how fast is the handover in practice?
- Can you book into my actual diary or software, or only send a booking link?
- How is the call charged: per call, per minute, by allowance, and what happens over the allowance?
- Where are recordings and transcripts stored, for how long, and will you sign a data processing agreement?
- Can I hear real or test calls in my own business's context before I commit?
How does UK GDPR affect the choice?
Whichever option you choose, the provider handles personal data on your behalf: names, numbers and the reason for the call. That usually makes them a processor, which needs a written agreement, and you remain responsible for telling callers how their details are used.
An AI receptionist adds two points. Callers should be told at the start that they are speaking to an AI assistant, and you should know where the speech and language models process call audio and transcripts. The ICO's guidance on AI and data protection is the place to start. A system can be built to support UK GDPR requirements, but compliance depends on how your organisation runs it.
Where does SpiderHunts fit?
We build the AI side: a custom AI receptionist for UK businesses, set up around your call types, connected to your diary and CRM, and handing over to your team, or to your existing answering service, on your terms. We also build sector versions, such as an AI receptionist for dental practices, an AI receptionist for law firms and an AI receptionist for estate and letting agents.
