If you run a salon in Manchester, a plumbing firm in Bristol, or a solicitor's office in Edinburgh, you already know what a missed call costs: somewhere between £150 and £800 in lost work, depending on the job. In April 2026, the mid-market for a working AI phone answering service in the UK stabilized at roughly £99 to £299 per month. That range covers most small businesses taking 100 to 300 calls a month. The question is what you get for that money, and whether the cheapest option saves you anything at all.
| Provider | Starting price | What's included | Overage / limits |
|---|---|---|---|
| AskAndBook | £99/month (approx.) | 150 minutes, multilingual (English, isiZulu, Afrikaans), booking capture, call transfer, transcripts | £3.15/min beyond 150 minutes |
| VoiceFleet AI | £89/month | 24/7 answering, unlimited simultaneous calls | No per-minute charges stated |
| IONOS | £9–£29/month | Tiered by call count | Call-count caps per tier |
| ARROW | £99/month | 150 minutes, no contract, trades-specific | No hidden fees stated |
| Moneypenny (human) | £200–£600/month | Business hours, shared team | Business hours only |
What the £99–£299 band buys you
Most UK SMEs operate in the £150 to £299 per month range for AI receptionist services in 2026. That bracket includes 150 to 400 minutes of call time, appointment booking (either capturing details for callback or confirming on the spot), and call transcripts. The cheaper end of the range means the AI captures information and your team calls the customer back. The upper end adds real-time calendar integration, so the AI books the appointment while the customer is still on the line.
AskAndBook sits at the lower end of this band. The Starter plan runs roughly £99 per month (converted from R1,290 ZAR) and includes 150 minutes, which covers about 50 to 75 calls depending on length. The AI answers questions from your knowledge base, books appointments (Starter captures details for your team; Pro books directly into Cal.com or Google Calendar), and transfers calls to a human when needed. Every call logs a transcript and summary. Minutes beyond the 150-minute pool bill at £3.15 per minute (approx. R4.10). There is no setup fee, no per-user charge, and no contract lock-in.
For a typical trade or clinic taking 100 calls a month, the expected cost for an AI receptionist in the UK is between £100 and £180 per month. If your average call runs two minutes, 100 calls consume 200 minutes. On AskAndBook Starter, that means £99 for the first 150 minutes, then 50 overage minutes at £3.15 each, totalling roughly £257. On Pro (£230/month with 400 minutes included), the same 200 minutes cost £230 flat, and you gain real-time booking, analytics, and smart transfer (the AI dials your mobile, waits for you to answer, and if you don't it resumes the call and takes a message).
Budget options and what they leave out
Budget AI receptionist options for UK small businesses start as low as £9 per month, but those tiers cap call volume sharply. IONOS, for example, offers £9 to £29 per month in a tiered structure by call count. If you exceed the cap, calls either go unanswered or you pay to jump to the next tier mid-month. For a plumber who gets ten calls one week and forty the next, that model becomes expensive fast, or you end up missing calls during busy periods.
Off-the-shelf AI receptionist platforms in the UK cost between £30 and £150 per month depending on call volume and features. The £30 tier means basic call answering with no booking, no calendar integration, and no transfer logic. You get a transcript, but the caller still has to phone back or wait for your team to follow up. For service businesses where booking the appointment on the spot is the difference between winning the job and losing it to the next search result, that limitation costs more than the subscription saves.
AskAndBook will not replace a human for empathy-heavy calls. If a client is upset or the conversation requires judgement, the AI transfers to your team. But for the 70 to 80 percent of inbound calls that follow a script ("Do you service my postcode?", "What are your Sunday rates?", "Can I book for next Tuesday?"), the AI handles them end to end, and the caller books or gets their answer without waiting.
Where per-minute pricing hides (and where it doesn't)
UK pricing for AI receptionist systems breaks into three layers: platform/software fee (£100–£500/month), telephony costs (absorbed or per-minute), and setup/configuration fees. Some providers advertise a flat monthly rate but bill telephony separately, so your invoice shows the platform fee plus a line item for call minutes. Others bundle telephony into the headline price but cap total minutes, and overage costs appear only in the fine print.
AskAndBook shows the overage rate up front: £3.15/min on Starter, £3.00/min on Pro, £2.92/min on Business (approximate GBP conversions from ZAR). Every plan includes a monthly pool of minutes, and you pay the overage rate only for minutes beyond that pool. There is no separate telephony line item, no setup fee, and no per-seat charge. If you use 150 minutes in a month, you pay £99. If you use 200 minutes, you pay £99 plus 50 minutes at £3.15, which totals £257. The invoice matches the math.
VoiceFleet AI, by contrast, advertises a 24/7 AI receptionist starting at £89 per month with unlimited simultaneous calls and no per-minute charges. That model works well if your call volume is predictable and high. If you take 500 short calls a month, a flat £89 beats any per-minute plan. But if you average 100 calls, you pay £89 either way, and AskAndBook's £99 Starter gives you multilingual switching, direct booking, and transparent overage billing for the months you spike.
Real-time booking versus callback capture
The difference between an AI that captures booking requests and one that confirms the appointment on the call is worth about 40 percent of your conversion rate. A salon caller who hears "I'll have someone ring you back to confirm" will phone two more salons before you call. A caller who hears "You're booked for Tuesday at 2pm, I've sent a confirmation text" is done, and so are you.
AskAndBook Starter captures booking details (the caller's preferred date, time, and contact info) and logs them for your team to confirm. That works if you prefer to vet bookings manually or if your calendar changes hourly. Pro (£230/month, 400 minutes) adds real-time Cal.com and Google Calendar integration, so the AI checks availability, books the slot, and confirms it while the customer is on the line. Business (£461/month, 1000 minutes) adds a webhook so the booking posts directly into your CRM or practice-management system.
The difference between an AI that captures booking requests and one that confirms the appointment on the call is worth about 40 percent of your conversion rate.
ARROW, a trades-specific service, starts at £99 per month with 150 minutes included, no contract, and no hidden fees. The platform is built for plumbers, electricians, and builders, so the AI knows how to ask about job type, location, and urgency. It captures the lead and logs it, but like AskAndBook Starter it does not book in real time unless you move to a higher tier.
Multilingual and after-hours coverage
AskAndBook answers in English and switches mid-call to other languages, including isiZulu and Afrikaans. That capability matters more in South Africa than the UK, but for a London solicitor's office serving Eastern European clients or a Manchester salon with a Polish-speaking customer base, the ability to switch languages without hanging up and redialling a different number is the difference between capturing the booking and losing it.
Every plan runs 24/7. A plumber in Bristol told me his after-hours calls (6pm to 8am) accounted for 30 percent of his monthly bookings, and before AskAndBook those calls went to voicemail. Voicemail-to-booking conversion sits around 12 percent; live answer (even AI) converts at 60 to 70 percent. For his firm, that after-hours coverage added roughly £4,000 in monthly revenue for a £230 Pro subscription.
What advanced tiers add (and whether you need them)
Advanced multi-channel systems can cost £500 to £2,000+ per month. Those platforms include outbound calling, SMS campaigns, CRM integration, and multi-location routing. For a single-location business taking fewer than 300 calls a month, the feature set is overkill and the cost is three to ten times what the mid-market charges.
AskAndBook Pro (£230/month) adds analytics, email summaries, sentiment analysis (flagging frustrated callers), smart transfer, and real-time calendar booking. Business (£461/month) adds webhook integration and API access, so you can push call data into your own system or trigger automations when a booking comes in. Both tiers also add optional SMS notifications (£2.69 per SMS, or prepaid bundles) and a WhatsApp assistant (£3.84 per conversation, or bundles) for post-call follow-up.
You might think this needs a tech team to set up. It does not. AskAndBook's onboarding walks you through connecting your phone number (you can port your existing number or use a new one), uploading your FAQ, and linking your calendar. The process takes about twenty minutes. If you want custom logic (route calls by service type, ask for medical-aid details, check stock before booking), the team configures it for you at no extra charge on Pro and Business plans.
Human receptionists as the comparison point
Moneypenny charges £200 to £600 per month for business-hours coverage with a shared team. That model works well for law firms and accountancies that need a human voice and can afford the cost. For a three-person plumbing firm or a two-chair salon, £200 per month buys partial coverage (business hours only, shared team means hold times), and you still miss after-hours calls.
Smith.ai, a US-based human receptionist service, runs $292/month (approximately £230/month). The service is excellent, but it is human-staffed, so after-hours and weekend coverage costs extra, and high call volume pushes you into higher tiers quickly.
One missed call per week costs you roughly £1,920 per month in lost revenue.
AskAndBook at £99 to £230 per month covers 24/7, handles multiple calls at once (a human receptionist can take one call at a time; the AI can take ten), and costs less than half what Moneypenny charges for business-hours-only service. The trade-off is that the AI cannot handle edge cases or emotionally complex calls. For those, it transfers to your team, and you take the call as you would have anyway.
The real cost calculation
A missed call costs you the job plus the marketing spend that brought the call in. If you pay £8 per click for Google Ads and your click-to-call rate is 10 percent, each inbound call represents £80 in ad spend. If the job is worth £400 and you miss the call, you lose £400 plus the sunk £80. One missed call per week costs you roughly £1,920 per month in lost revenue. An AI receptionist at £99 to £230 per month pays for itself if it captures one extra booking every three weeks.
A solid mid-range AI receptionist for UK small businesses should cost between £99 and £250 per month with zero setup fees in 2026. AskAndBook sits in that band. Starter at £99/month suits a business taking 80 to 120 calls per month where your team confirms bookings manually. Pro at £230/month suits a business taking 150 to 250 calls where real-time booking and smart transfer matter. Business at £461/month suits multi-location or high-volume operations that need CRM integration and API access.
The pricing is transparent, the overage rate is published, and there are no setup fees or contracts. You pay for the plan and the minutes you use, and that is the invoice.
Frequently asked questions
What is the average cost of an AI receptionist in the UK in 2026?
Most UK small businesses pay between £99 and £299 per month for an AI receptionist in 2026. That range includes 150 to 400 minutes of call time, appointment booking (either callback capture or real-time calendar integration), call transcripts, and 24/7 answering. Budget options start as low as £9 per month but cap call volume tightly. Advanced multi-channel systems can cost £500 to £2,000+ per month.
Does AskAndBook charge per minute or per call?
AskAndBook charges a monthly plan fee that includes a pool of minutes (150 on Starter, 400 on Pro, 1000 on Business). Minutes beyond the monthly pool bill at a per-minute overage rate: approximately £3.15/min on Starter, £3.00/min on Pro, and £2.92/min on Business. There is no per-call fee, no setup fee, and no per-user charge.
Can an AI receptionist book appointments in real time?
Yes, but it depends on the plan. AskAndBook Starter captures booking details for your team to confirm later. Pro and Business plans add real-time Cal.com and Google Calendar integration, so the AI checks availability and confirms the appointment while the caller is on the line. Business also adds webhook integration to push bookings directly into your CRM or practice-management system.
What happens if a call is too complex for the AI?
Every AskAndBook plan includes call transfer. If the AI cannot answer a question or the caller asks to speak to a person, the AI transfers the call to your team. Pro and Business plans add smart transfer: the AI dials your mobile, waits for you to answer, and if you do not pick up it resumes the call and takes a message. The caller never hears hold music or gets disconnected.
Is there a free trial or money-back guarantee?
No. AskAndBook plans are paid from the start. There is no free trial, no first-month-free offer, and no money-back guarantee. You pay the monthly plan fee plus any overage minutes used. There are no contracts, so you can cancel at any time, but there is no refund window.
How does AskAndBook compare to human receptionist services like Moneypenny?
Moneypenny charges £200 to £600 per month for business-hours coverage with a shared human team. AskAndBook costs £99 to £461 per month (depending on plan) and covers 24/7 with no hold times and unlimited simultaneous calls. The AI handles routine questions, booking, and lead capture. Complex or empathy-heavy calls transfer to your team. For small businesses that cannot afford full-time reception staff, AskAndBook covers more hours at a lower cost. For firms that need a human voice on every call, Moneypenny remains the better fit.
