AI Phone Answering for Restaurant Bookings: What It Costs a UK Venue and When to Skip It (2026)

A UK restaurant can put an AI voice on its phone for about £99 a month ex VAT at 300 calls, but the products built for restaurants mostly do not publish a price. What is on sale, the arithmetic, the rules on recording, and when a booking link does the job.

An AI receptionist for a UK restaurant costs about £99 a month ex VAT at 300 calls a month if you buy a generic one, while the two restaurant-diary products from Access and SevenRooms publish no price. Whether it pays depends on a number only you can get: how many calls you miss, and how many of those wanted a table. Count for two weeks, put a booking link on your Google Business Profile, and only then test an assistant for a month.

What you can buy, and what it costs

At 300 calls a month the generic UK product with a public tariff, Fasthosts AI Receptionist, costs £99 ex VAT on its unlimited plan, and the restaurant-specific products from Access and SevenRooms publish no price at all. If you run one venue, you cannot budget for a product that will not tell you its price. The tools built to write bookings into a restaurant diary are sold by demo, and the ones with a price list are generic or priced in dollars.

In the 300-call column, Lite is £39 plus 270 extra calls at 49p and Plus is £69 plus 200 at 39p. Fasthosts lists appointment booking from Plus upwards, so Lite may not book at all. It has no minimum commitment and a one-month free trial, and its call forwarding is on every plan.

Access describes Collins Call AI as answering bookings around the clock and logging the booking and transcript in the Collins Evo diary, so you need that diary to use it. Its own blog claims 30% to 50% fewer missed calls, without saying how that was measured. SevenRooms says its Voice AI answers inbound calls for reservations and changes. Neither page mentions a UK price. Slang.ai lists no pound price and Goodcall prices in dollars, so I would not budget around either.

Does it pay for itself?

Under the assumptions below, one booking is worth about £63 in gross profit, so an assistant at £99 a month has to land two bookings a month that you would otherwise lose before it has paid for itself. Three covers at £30 before VAT and a 70% gross margin gives £63. Gross profit is sales minus the cost of food and drink, so staff, rent and energy still have to come out of it.

The harder part is the funnel before the booking. Of the calls you miss today, only some wanted a table. Of those, some ring back or book online. And the assistant gets the rest right only some of the time. The sliders start at 40%, 50% and 70%. Move them to match your venue. PolyAI, a vendor, says an unnamed UK pub restaurant chain missed 30% of its calls, and that its voice assistant now handles 70% of all guest calls in full. It is a sales case study from a chain, so it tells you little about a forty-cover bistro.

A no-show costs more than a miss, and a phone assistant does not fix it. OpenTable's Restaurant Impact Report, reported on 6 October 2026, puts the average cost of a UK no-show for a table of two at £55.70; that is vendor research with no sample size given. For the policies that do cut no-shows, see our guide to no-show fees and deposits.

Do the free things first

Two weeks of counting and one booking link cost nothing and answer the question better than a vendor demo. Keep a tally by the till of every call you miss, ring each one back, and write down whether they wanted a table. That tally is the first input to the calculator above.

Then add a booking link to your Google Business Profile. Google's help page describes adding a link for booking, food ordering or pickup and delivery under your profile, and our guide to booking systems for independent restaurants covers what each system charges and the point that bookings from your own link and phone are free on the big marketplaces. Put the same link in your voicemail message with your opening hours. If you already run one of those systems, ask your booking provider whether it has a phone assistant before you shop elsewhere: that is how Access and SevenRooms sell theirs.

What the rules say

You must tell people you are recording a call and why, and a vendor that records or transcribes calls for you is a processor that needs a contract. The ICO says you must tell people you are recording a call and why, and that a recorded message is good practice. That guidance is written for staff calls, and nothing in it suggests a guest is owed less. The ICO's page on the right to be informed says you must give privacy information when you collect personal data, and a name and phone number for a booking is personal data.

Article 28 of the UK GDPR requires processing by a processor to be governed by a contract, so ask the vendor for its data processing terms before the trial starts, and ask where the recordings are stored. Telling callers up front that the voice is automated costs one sentence and heads off a complaint. Ask the vendor to include it and listen to the recording yourself.

Where it goes wrong

Phone bots have been pulled in the US: Anthony's Coal Fired Pizza dropped its AI order line at all 59 locations in 2023, and McDonald's announced in June 2024 that it was ending an IBM test at selected drive-thrus. Both were ordering lines in the US, and neither was a reservation system. The IBJ's report on the McDonald's test lists the kind of order errors that went viral.

Carl Bachmann, chief executive of BurgerFi, which owns Anthony's, gave the reason:

UK operators sound torn. Rob Barr, co-owner of the three-pub Barr & Barr Hospitality, told the Morning Advertiser in September 2025 that "when the phone is ringing during busy service, you don't want to miss out on a booking or inquiry". He also said the company had started looking at AI to be more efficient without losing "that hospitality charm". Tim Skinner, licensee of the Devonshire Arms in Marylebone, was blunter in June 2026: "I wouldn't want it to ever be guest facing."

An 8x8-commissioned survey of 2,000 UK adults found 83% prefer speaking to a human when contacting organisations and 4% prefer a chatbot or virtual agent. It is a vendor-funded poll about customer service in general, not about restaurants, so take it as a reminder that callers notice when a machine answers.

Keep a person on the calls that matter. Access says its assistant cannot answer questions that are not in the policies you upload and records the request for follow-up instead. Send complaints, allergy questions and celebrations to your own number, and test the assistant yourself in a regional accent with the dining room noise on.

My recommendation

Run it as a one-month test after the free fixes, on a plan with no commitment, and cancel it if it lands fewer than two bookings. Fasthosts offers no long-term commitment and a one-month free trial. The restaurant-specific products start with a demo, which is one more reason to ask your booking system first.

Cancel also if regulars mention the voice, or if it passes so many calls back to you that you have gained nothing.
