Which One Makes Sense for Your Business Frequently Asked QuestionsEvery trades business eventually hits the same wall. You are on the tools from seven in the morning until six at night. Your phone is ringing while you are under a boiler in a Bradford terrace. WhatsApp messages are stacking up. Your Saturday morning is gone answering enquiries that came in Friday evening.
The instinct is to hire someone to handle it. A receptionist, a part-time admin, anyone who can pick up the phone and stop the bleeding. That instinct is not wrong. But the cost of hiring is significantly higher than most trades owners calculate when they post the job advert. And the alternative, an AI receptionist on WhatsApp, has become capable enough in 2026 that the comparison deserves a clear-eyed look.
This is that comparison. Real numbers, real trade-offs, no sales pitch.
1. What a Human Receptionist Actually Costs in the UK
The headline salary number on a job listing is not what you pay. Once HMRC finishes with you, the actual employer cost is substantially higher. Here is a worked example for a part-time receptionist in the UK in 2026.
| Cost item | Annual amount |
|---|---|
| Gross salary (20 hrs/week, National Living Wage at £12.21/hr) | ~£12,700 |
| Employer National Insurance (13.8% above threshold) | ~£900 |
| Statutory holiday pay (5.6 weeks) | ~£1,370 |
| Auto-enrolment pension contribution (3% employer) | ~£380 |
| Recruitment cost (job board or agency, one-off spread over 2 years) | ~£500 |
| Sick leave cover (UK average is 4.6 days/year) | ~£270 |
| Total annual employer cost | ~£16,100 |
That is for twenty hours a week, which most trades businesses find is not enough once they account for lunch breaks, phone downtime, and the hours they are actually unreachable. A full-time receptionist at the same wage lands at around £28,000 to £32,000 per year all-in.
In London and the South East those numbers climb further. A part-time role in central London paying the London Living Wage sits closer to £19,000 to £21,000 a year once you add the same employment costs on top.
The Office for National Statistics puts the median annual earnings for administrative and secretarial occupations in the UK at around £26,000 full-time equivalent in 2025. For a small plumbing, electrical, or HVAC business, that is a significant fixed overhead before a single call is answered.
2. What You Get for That Money
A good human receptionist brings things an AI genuinely cannot match. It is worth being clear about what those are before talking about where the comparison tilts the other way.
A skilled receptionist reads the room. They can tell from the tone of a caller's voice whether someone is genuinely distressed or just impatient. They adjust. They de-escalate. They build a small, real rapport over repeated calls with the same customer. That matters for businesses where long-term customer relationships are the engine of referrals.
They handle edge cases without a script. A customer rings asking whether you cover a postcode that is technically outside your zone but next door to your last three jobs. A human can make a judgment call in real time. An AI follows the rules you set.
They can multitask across channels in a nuanced way. A receptionist who answers the phone can simultaneously spot that an email just came in from an urgent commercial client and flag it before you finish the current call. That kind of layered attention is genuinely hard to replicate.
Those are real advantages. They are also advantages that apply to a minority of interactions. Most of the calls a small trades business receives are straightforward: pricing questions, appointment bookings, service area queries, follow-up on a previous job. Routine work that does not need human judgment.
3. What an AI Receptionist Costs
An AI receptionist for a UK trades business in 2026 operates on your existing WhatsApp Business number. You configure it once with your services, your rates, your service area, and your emergency keywords. It then handles incoming messages around the clock.
The cost structure is completely different from employment. There are no National Insurance contributions. No holiday pay. No pension. No sick days. No notice period. No recruitment cycle if the previous person leaves after three months.
For current Automatyn pricing broken down by conversation volume and features, see the pricing page. Plans start free for lower-volume businesses and scale with usage. Even at the upper end, the annual cost is a fraction of a part-time salary.

Here is how the two options compare across the dimensions that matter most for a UK trades business.
| Factor | Human receptionist | AI receptionist |
|---|---|---|
| Annual cost | £16,000 to £32,000+ | See pricing page |
| Available hours | Contracted hours only | 24 hours, 7 days |
| Response time | Seconds to minutes (when working) | Under five seconds |
| Sick days / holidays | Yes, you still pay | None |
| Emergency routing | Depends on training and attention | Configurable, consistent, instant |
| Complex enquiry handling | Strong | Good for common cases, hands off otherwise |
| Relationship building | High | Low to medium |
| Setup time | Weeks (recruit, onboard, train) | Under ten minutes |
| Scale up / down | Slow and expensive | Instant plan change |
| Risk of leaving | High (average UK admin tenure ~18 months) | None |
The pattern in this table is consistent: the human receptionist wins on quality for complex interactions, the AI wins on cost, availability, and reliability for everything routine. The question is what proportion of your actual enquiries are complex.
For most plumbers, electricians, HVAC engineers, and similar trades, the answer is that the vast majority of inbound contacts are routine. Pricing questions. Service area. Can you come Thursday. What is your call-out rate. Is this an emergency job or can it wait. These do not require a skilled human. They require an accurate, fast, polite response at any hour.
5. Where an AI Receptionist Falls Short
Honest comparison means listing the genuine limitations, not just the headline savings.
The AI cannot make judgment calls outside its configuration. If a customer calls from a postcode you marked as out of area but they are actually three streets inside your boundary and the job is worth £800, a human might make the call. The AI will decline politely and stick to the rules you set. That is a trade-off, not a failure.
Complex complaint handling needs a person. A customer who is already angry about a previous job and rings in a heightened state benefits from a human who can hear the emotional charge and respond accordingly. An AI will be polite and accurate, which sometimes escalates rather than de-escalates. If you have a recurring complaints pattern, a human touch at that stage preserves the relationship in a way an AI cannot reliably replicate.
Outbound follow-up is currently limited. A receptionist proactively chases outstanding quotes, reminds customers that a service window is coming up, and keeps tabs on which enquiries went cold. An AI receptionist today is primarily reactive, not proactive. That gap is narrowing, but it exists.
Voice calls still need coverage. An AI receptionist on WhatsApp handles WhatsApp. It does not answer your landline or your mobile directly. If a significant portion of your inbound enquiries are voice calls rather than messages, you need a separate solution for those, or you need to set a missed call divert that pushes callers onto WhatsApp.
6. Which One Makes Sense for Your Business
The answer depends on three things: your volume, your average job value, and whether your customers already use WhatsApp to contact you.
AI receptionist is the better starting point if:
- You are a sole trader or small team where the cost of a part-time employee is a real constraint.
- Your enquiries come in across evenings and weekends when a human receptionist would not be working.
- Most of your inbound messages are routine: pricing, availability, service area.
- You are already receiving WhatsApp messages from customers or are willing to direct them there.
- You want to test whether structured customer communication converts better before committing to employment costs.
A human receptionist adds real value if:
- You are running three or more engineers and the volume of inbound enquiries justifies the overhead.
- A significant share of your work is commercial or high-value residential where the relationship component matters over months and years.
- You deal with a high volume of complex or contentious enquiries that need genuine judgment in real time.
- Your customer base is older and predominantly uses voice calls rather than messaging apps.
These categories are not mutually exclusive. Plenty of trades businesses use an AI receptionist to handle WhatsApp and out-of-hours contacts, with a human covering inbound calls during business hours. The AI covers the gap for a fraction of the cost of expanding the human role.
For the maths on what missed enquiries are actually costing your business before you make this call, see the breakdown in The Real Cost of Missed Calls for UK Small Businesses.
The Bottom Line
A part-time receptionist in the UK costs somewhere between £16,000 and £21,000 a year once you account for employment costs beyond the headline wage. A full-time one is closer to £28,000 to £32,000. That is a real commitment, and it comes with the risk of turnover, sick days, and a gap in coverage the moment they are unavailable.
An AI receptionist costs a fraction of that, covers all hours, answers in under five seconds, and never takes holiday. It is not a perfect replacement for a skilled human. It does not need to be. For the routine enquiries that make up the majority of inbound contacts for most UK trades businesses, it is fast enough, accurate enough, and available enough to pay for itself many times over.
The decision is not really AI vs human. It is about which combination of the two makes sense at your current volume and budget. For most sole traders and small teams, starting with an AI receptionist and adding human support only when the volume genuinely demands it is the lower-risk, lower-cost path.
Frequently Asked Questions
How much does a part-time receptionist cost a UK small business in 2026?
A part-time receptionist working 20 hours a week in the UK costs between £13,000 and £18,000 a year once you include the National Living Wage, employer National Insurance, statutory holiday pay, and pension auto-enrolment. In London and the South East, that figure climbs higher. The number on a job listing understates the actual employer cost by 20 to 30 percent.
Can an AI receptionist handle emergency calls for a trades business?
Yes. You configure emergency keywords specific to your trade: burst pipe, flood, gas smell, boiler not firing, no hot water. When a customer message hits one of those words, the AI agent skips the booking flow and sends an immediate alert to your mobile. You ring back yourself. The AI does not guess at emergencies; it routes them to you instantly.
What happens outside of office hours with an AI receptionist?
The AI agent works around the clock with no additional cost. A human receptionist costs the same whether they answer two calls or two hundred, but they are only available during their contracted hours. Evening and weekend enquiries, which are the peak window for many trades, are handled by the AI without overtime pay or on-call arrangements.
Is an AI receptionist good enough to replace a real person entirely?
For first-contact handling, qualifying questions, booking, and routine enquiries, yes. For complex jobs needing site assessment, delicate complaint handling, or situations where a customer specifically asks to speak to a person, the AI hands off immediately. Most trades businesses find the AI handles 80 to 90 percent of incoming contacts end to end.
How long does it take to set up an AI receptionist for a trades business?
With Automatyn you fill in your business details, services, prices, and postcodes covered. The AI builds your agent configuration automatically.
