Three shifts, seven days, fifty-two weeks a year. That is the actual shape of "round-the-clock" cover once you stop pricing it like a single job, and it is why a 24/7 virtual receptionist quote and a human rota quote almost never land on the same number.
A 24/7 virtual receptionist answers every inbound call, day or night, without a rota, a night-shift premium or a single hour left uncovered. Buy it as an AI-only service and it typically costs £99 to £299 a month in the UK, not far off what a single evening shift alone would cost to staff properly with a person. Cover the same hours with humans instead and you are pricing three shifts, not one, with 20% to 33% on top of base pay for shifts between 10pm and 6am before a single call gets answered. That gap, not the marketing copy, is what actually decides whether round-the-clock cover is worth building.
An after-hours service plugs the gap once the shutters come down: evenings, weekends, the odd bank holiday. A genuine 24/7 virtual receptionist promises something larger, every hour of the year, including the ones your daytime team already covers, with nothing switched off in between. The after-hours cover guide is the right read if evenings and weekends are your actual gap. This one is for the smaller group of businesses where the phone genuinely never gets to rest.
Emergency trades on call for a burst pipe or a lockout. Hotels and restaurants taking bookings from guests sitting in a different time zone. Support lines with a contractual answer-time SLA that does not pause at 6pm. That is the shortlist. Most other businesses have an evening gap and a quiet 3am, not a genuine dead hour, and pricing the wrong tier is how a business ends up paying for cover it never needed.
Price a single receptionist and you're pricing one shift, daytime, standard hours. A UK receptionist salary sits at roughly £25,000 to £32,000 in salary before employer National Insurance and pension, and that figure is what most "cost of a receptionist" comparisons quote. It covers exactly one shift. Round-the-clock cover needs three, plus weekend rotation layered on top of the first, and the 10pm-to-6am slot does not pay the daytime rate: 20% to 33% on top of base pay for shifts between 10pm and 6am is standard UK practice, before a weekend has even been costed. A "simple" front-desk hire turns into a small team with a rota to manage, holiday cover to arrange and sickness to absorb.
| Coverage model | What it actually covers | Typical cost |
|---|---|---|
| Daytime-only human hire | One shift, standard hours | £25,000 to £32,000 in salary before employer National Insurance and pension, one shift only |
| Human plan plus after-hours add-on | Evenings, weekends and holidays bolted onto the day shift | Adds £35 to £75 or more a month to a standard answering plan |
| Full human night rotation | Every hour, every day, three shifts plus weekend cover | Day-shift salary plus a 20% to 33% on top of base pay for shifts between 10pm and 6am uplift, multiplied across the extra shifts |
| AI-only 24/7 | Every hour, every day, one flat rate | £99 to £299 a month |
| Hybrid: AI plus human on-call | AI answers, a person is on call for anything sensitive | £500 to £2,000 a month |
The gap is starkest at the hours nobody wants to staff. AI agents cost $0.25 to $0.50 per interaction compared with $3.00 to $6.00 for human agents, an 85% to 90% cost reduction, and that gap does not shrink at 3am the way a human wage bill grows. A night-shift human costs more per hour than a daytime one, every time. A night-shift AI call costs exactly the same as a daytime one. That single fact is the entire economic case for using AI specifically in the hours a rota is hardest to fill, rather than across the whole day on principle.
74% of customers now require 24/7 service availability, according to Zendesk's 2026 customer experience research. That is the expectation side of the argument. The staffing side is narrower, and it is worth being honest about which side your business actually sits on before you buy anything. If your call pattern is genuinely evenings, weekends and the odd holiday, after-hours cover solves it for a fraction of full round-the-clock pricing. True 24/7 earns its keep only where the call pattern has no dead zone at all.
The wider comparisons sit elsewhere. The main AI receptionist guide covers what one actually does beyond the phone. The UK cost breakdown runs the fuller pricing table against a human hire. The phone answering service guide covers how the escalation logic gets built, so a genuine emergency still reaches a person at 4am rather than a script. Digital receptionist widens the same idea past the phone to chat and booking, and the AI versus traditional answering comparison is worth a look if a human service is still on your shortlist.
It's a receptionist service, almost always AI now, built to answer every call at any hour of the day or night, not just during opening hours or the evening gap. It handles routine questions, takes bookings where your calendar allows it, and hands anything genuinely urgent to a person instead of a script.
An AI-only service typically runs £99 to £299 a month in the UK. Staffing the same hours with people means a full daytime salary plus a 20% to 33% on top of base pay for shifts between 10pm and 6am uplift across three rotating shifts, which is why almost nobody prices true round-the-clock human cover the way the marketing implies.
Yes. After-hours cover plugs the evening, weekend and holiday gap once your team has gone home. True 24/7 cover promises every single hour, including the ones you already staff, which only a small group of businesses, emergency trades, hospitality, contractual SLA desks, genuinely need.
For most businesses, yes, somewhere in the chain. AI handles the routine volume at a fraction of the cost, but a genuine emergency, a complaint, or anything sensitive still needs a named on-call person and a clear rule for when a call gets escalated to them.
Usually not. Pull the call log and check for a genuine gap at 3am, not just a quiet patch after 6pm. If the gaps cluster in evenings and weekends, after-hours cover handles it for a fraction of full round-the-clock pricing; true 24/7 earns its cost only when there is no dead hour at all.
Add up the actual dead hours before buying anything: check whether the call log shows a genuine gap at 3am or just a slow patch after 6pm. A locksmith or a hotel with no dead hour should price the AI-only route first, since it beats staffing a night shift on almost any measure. Everyone else is very likely shopping for after-hours cover with better marketing attached. Start at contact and bring the call log.
