AI receptionist for plumbers. Calls answered, jobs qualified.

• ✓
  42.1%

  122 of 290 outbound dials to working plumber numbers reached a person in our study.

• ✓
  66.6%

  Of 647 unanswered outbound calls across the study, 431 rang out without reaching voicemail.

• ✓
  1,371

  Outbound calls recorded across 38 calling days, with the method and limitations published in full.

These were outbound cold calls from an unknown number, not inbound customer calls. The results measure trade-business reachability, not how businesses respond to paying customers. Read the full UK trade phone answering study.

A basic answering service takes a name and a number, and you chase the rest later. Praxum picks up the calls you cannot take and replies to texts and WhatsApp messages (where enabled). It does the work between first contact and a booking: it asks the plumbing questions you approve, checks your service area and how urgent the job is, then books it, asks you to call back or alerts you, following your rules.

Where plumbers lose the job

• ✓
  Missed calls during jobs

  You cannot answer with your arm down a U-bend, and the caller rings the next plumber on Google.

• ✓
  Thin, unqualified messages

  "How much?" with no job detail, no postcode, no photo — a callback waiting to be wasted.

• ✓
  A messy diary

  Double-bookings, vague addresses and unclear jobs because details were never captured properly.

The phone is the biggest leak, and WhatsApp is where homeowners reply with photos. See AI call answering for sole trader plumbers and the WhatsApp booking system for plumbers.

While building Praxum, we made over a thousand calls to UK trade businesses. These patterns came up again and again. They are our own observations, not customer results.

• ✓
  The voicemail that says it all

  One heating firm’s voicemail told callers “we are dealing with a high volume of calls right now”. The voicemail tells callers the firm is busy, but leaves them waiting for a callback.

• ✓
  Paying for leads nobody answers

  If you pay for leads from sites like Checkatrade or TrustATrader, an unanswered call is money you have already spent.

• ✓
  The message that waits for a callback

  In small family-run firms the call often reaches a partner, who takes a name and passes it on. The job then waits until the plumber is free.

• ✓
  Same-day and emergency

  Active leaks, no heating, burst pipes. Praxum checks urgency and water status, captures the postcode, and flags or escalates the genuine emergencies fast.

• ✓
  Planned work and quotes

  Bathrooms, boiler replacements, landlord work. It captures the detail and photos so you can quote properly, and books the routine jobs without interrupting your day.

You set the coverage hours, what counts as urgent, which postcodes you cover and what should book automatically versus wait for you. For an after-hours call, Praxum can collect the caller’s name, number, postcode, problem type, whether water is actively leaking and any useful photos before applying those rules.

• Immediate alert: genuine emergencies are flagged to the contact you nominate, with the captured job details attached.
• Escalation: if the first contact does not respond, the alert can move to a second person according to the chain agreed during setup.
• Morning queue: routine quotes, planned work and non-urgent questions are captured without waking you and held for the next working period.
• Honest handover: the customer receives the next step your rules allow; Praxum does not promise attendance that nobody has confirmed.

One-van plumbers use it for the calls they physically cannot take on the tools: see sole trader answering. Teams with an office use it when every line is busy: see overflow call answering. Evenings, weekends and bank holidays are covered in the section above.

If you are looking for a virtual assistant for the phone side of a plumbing business, this is the admin Praxum takes on:

• Answers the calls you cannot take, in your business name.
• Asks your job questions and checks the postcode against your service area.
• Books the job into your Google Calendar where your rules allow.
• Texts the customer a booking confirmation.
• Alerts you straight away for emergencies, and sends a missed-call text where an SMS-capable caller number is available.
• Sends a weekly summary so you can see what came in.

It does not do your invoicing, payments or accounts, and it does not run your wider admin. See what is included for the full list.

CustomerHi, my boiler’s stopped and there’s no hot water. Can someone come out?

PraxumI can get this to the plumber now. Is there any water leaking, or is it only the hot water and heating that have stopped?

CustomerNo leak, just no hot water or heating.

PraxumThanks. What is your postcode, and is this a home or a rental property?

CustomerM20, it’s my own home.

PraxumGot it — you’re in the area. Send a photo of the boiler on WhatsApp if you can, and I’ll offer you the next available slot.

The plumber receives: "Boiler — no hot water or heating, no leak, M20 (in area), homeowner, photo received, slot offered." A qualified job, ready to action, instead of a missed call.
