AI receptionist vshiring a human receptionistfor plumbers.

This is the question almost every comparison skips, and it decides whether you should spend on AI or on a salary.

• Phone-coverage problem

  Calls ring out while you are under a sink, enquiries arrive after hours, and several people call at once on a busy Monday. You are losing jobs you already earned the right to win because nobody picked up.

• Staffing problem

  Invoices are not being chased, suppliers need coordinating, engineers need rescheduling, landlords need managing, complaints need human care, and someone needs to be physically present in the office.

An AI receptionist solves the first problem extremely well and the second one not at all. It answers, qualifies, routes and can book according to your connected setup. It does not chase late payment or talk a frustrated commercial client down over twenty minutes.

If you mostly need the phone answered properly, a £30,000 salary is an expensive way to buy coverage. If you need a genuine office person who happens to answer calls too, AI will not replace them, though it can take the phone load off so they get real work done.

The salary is never the real number. For the 2026/27 tax year, the cost builds from wage, employer National Insurance, pension, optional cover and recruitment.

• Salary range

  Salary platforms vary. Indeed reports UK receptionist pay around £31,500, Glassdoor around £24,300, and Reed listings can sit in the mid-to-high £20,000s. Treat the market as broadly mid-£20,000s to low-£30,000s depending on hours, location and duties.

• National Living Wage floor

  From 1 April 2026, the National Living Wage for workers aged 21 and over is £12.71 per hour. At 38 hours a week, that is about £25,115 before employer costs; at 40 hours, about £26,437.

• Employer National Insurance

  For 2026/27, employer NI is generally 15% on earnings above the £5,000 Secondary Threshold. On a £28,000 salary, that is roughly £3,450 on top of the wage.

• Workplace pension

  Auto-enrolment usually requires a minimum employer contribution of 3% of qualifying earnings. With the lower qualifying-earnings level at £6,240, that is around £650 a year on a typical receptionist salary.

A realistic all-in cost for one full-time receptionist sits around £28,700-£39,700 a year before recruitment, equipment or software, and that buys contracted weekday hours rather than 24/7 coverage.

• First-year cost

  Praxum is £1,200 to set up plus £450 per month, making the first year £6,600 at the current price.

• Ongoing annual cost

  From year two, the current monthly rate totals £5,400 per year, subject to any agreed change in scope or pricing.

• What the comparison covers

  Phone answering, qualification, routing and booking—not a human employee’s wider administration or physical office work.

Compared with the employment scenarios above, Praxum is roughly 77%-83% less in the first year for the defined enquiry-handling work. That is a cost comparison between different operating models, not a claim that AI replaces every responsibility of an employed receptionist.

An AI receptionist like Praxum is built to handle the calls a busy plumber cannot get to. For a trade business, that means:

• Answer calls that would otherwise go unanswered, including while you are on a job, on another call or closed for the night
• Identify whether the caller needs an emergency response, routine quote, existing-job update or supplier conversation
• Collect name, address, problem, urgency and contact details
• Check the postcode against your service area so you do not book work you cannot reach
• Separate emergencies from routine work instead of treating every call the same
• Book appointments into your connected calendar when booking is enabled
• Alert or route urgent enquiries to your on-call engineer according to your escalation rules
• Send a clear summary by text or WhatsApp so nothing gets lost
• Handle several calls at once during storms, cold snaps and Monday-morning spikes
• Escalate anything it is not confident about to a human

The point is not to replace an office person. It is to stop good enquiries leaking away when you are too busy to answer, protecting demand you already paid to generate through your van, reviews, Google presence and lead platforms.

A capable employed receptionist does plenty that no call-handling AI can do properly:

• Office administration: paperwork, quotes, invoicing and filing
• Supplier and merchant coordination through the day
• Rearranging engineers as jobs overrun or emergencies change the schedule
• Complaint resolution that needs patience, memory and judgement
• Commercial account management with landlords, agents and contractors
• Physical presence: visitors, deliveries and office tasks
• Unstructured work that changes hour by hour and cannot be scripted cleanly

If your business needs that, you need a person. The mistake is buying a person only to answer the phone, or buying AI when you actually need an administrator.

• A burst pipe at 2am

  An employed receptionist is asleep. AI answers, recognises urgency, captures the address, checks service area and routes or alerts according to your escalation rules. Winner: AI, because this is after-hours coverage.

• Three quote calls while you are under a sink

  A single receptionist can only take one conversation. AI can answer all three, qualify each and move suitable enquiries towards booking. Winner: AI, on concurrency alone.

• A complicated commercial complaint

  A managing agent is unhappy about disputed invoices across several properties. That needs tone, account memory, negotiation and follow-up. Winner: human, with AI escalating rather than guessing.

Choose AI first when the job is mainly coverage, capture and qualification:

• You or your engineers miss calls while working
• The main need is answering, qualifying, triaging and booking
• Calls arrive outside office hours
• Several enquiries sometimes land at once
• You want consistent postcode and service-area screening on every call
• You are not ready to fund a full-time office role
• An existing admin needs overflow cover, not replacing

For a one-van business, see AI call answering for sole trader plumbers. For busy daytime call spikes, see overflow call answering for plumbers.

Hire a person when the role is broader than answering calls:

• The role includes substantial office administration
• Someone must manage engineers and suppliers all day
• Complaints and accounts need prolonged human judgement
• Physical presence in the office matters
• The work is varied and unstructured beyond a defined call flow
• The employee will add value across many responsibilities, not just inbound calls

A hybrid suits growing plumbing firms where there is already a dispatcher, administrator or office owner handling exceptions.

• AI handles routine first response

  It answers, qualifies, checks postcode, captures job detail, books where configured and catches overflow.

• Your person handles judgement work

  Complaints, commercial accounts, awkward schedule changes and exceptions stay with the human who understands the business.

• After-hours capture stays covered

  Calls are not lost just because the office is closed, and routine enquiries can be held for business hours.

• Office staff get protected

  Your skilled admin stops drowning in repetitive calls and gets back to work that actually needs them.

Ignore generic claims like "every missed call is worth £500." Use your own numbers. The honest way to value missed calls is:

To compare options, work out how many extra jobs each choice needs to pay for itself:

For example, if employing someone all-in costs about £32,000 a year and your average job earns £180 gross profit, that role needs roughly 178 extra booked jobs a year to justify itself on calls alone: around 3-4 a week.

If most of those jobs are routine bookings AI could capture, the maths starts to favour AI plus your own time. Use the missed calls calculator before committing to either route.

AI is not magic, and a trustworthy comparison says so. Watch for misunderstood callers, integration errors, outages and over-automation around safety-critical calls.
