What can go wrong with an AI receptionist for an electrical business

The worst thing an AI receptionist can do for an electrician is handle a dangerous call badly. Someone reports a burning smell and it cheerfully takes a message for tomorrow. That's why this article opens there, and why I'd never switch one on before the safety wording's been written, signed off and tested.

We sell one of these, so you could fairly expect me to play the risks down. I won't. You need them in front of you before buying from us or from anybody.

One warning on the evidence. No independent test of AI receptionists on UK trade phone lines turned up, and most surveys in this area are funded by companies with something to sell. So what follows is the wider evidence plus my own judgement.

Danger calls

No receptionist should treat these casually. An AI only knows a call's urgent if the caller says so, and frightened people don't use tidy language. They say "it's gone bang", "there's a funny smell" or "the socket's gone black".

Below is what the official guidance says, and what I'd want a business to have it say. The job of setting this falls to you. Have a qualified person sign off the final wording. If you're qualified, treat it as you would a certificate. Never assume a provider has done it.

In Northern Ireland, 105 doesn't work. NIE Networks is on 03457 643 643, and 999 covers a fallen line or sparking equipment. That came from a comparison site, because NIE Networks' own page wasn't opened, so check it.

Rules to sit alongside the wording:

• If the caller isn't sure it's an emergency, it shouldn't judge. It should tell them to ring 999, and tell you.
• The safety line comes first. Details come second.
• No diagnosing, and no instructions on testing or resetting anything.
• It should try to transfer the call to you, if that's been set up.
• Out of hours, be clear when nobody can attend. "We can't come out tonight" beats silence.

Now test it. Ring in and talk like a panicking customer: "it's gone bang", "my husband got a shock off the cooker", "there's a wire on the road". Repeat after any change.

Selling emergency call-outs? Then the safest arrangement is an emergency number that reaches you directly, with the AI on a separate enquiry number.

Storm days and power cuts

A storm can fill your phone with people who need their network operator, not an electrician. 105 is free from a landline or mobile.

• Have it ask if the neighbours are off, then give 105.
• Stop it saying "someone will come out" to a street-wide power cut.
• Watch usage. I'd expect a storm to mean a heavy month on any plan charged by the call, though that's an expectation and not a measurement.

Callers who won't talk to a machine

You'll hear this objection most, and the evidence is fairly consistent.

The Gartner survey pre-dates today's voice AI. The hang-up figure is what people say they'd do, from a company selling human answering. Independent data on what callers really do didn't turn up.

On the other side, Ofcom has reportedly seen only "limited evidence" of AI causing systemic harm to telecoms customers. And for an electrician with the power off and both hands busy, the real contest is AI against nobody. Just 6% of UK adults told YouGov and Answer4u they'd leave a voicemail.

To soften it:

• Say it's an AI straight away. In a Five9 survey, 76% of UK respondents (1,000 in the UK) rated being told as very or extremely important. Vendor research, but sensible.
• Keep the greeting short.
• Offer a route to you: "I can take your details and Sam will ring you back by 4."
• Read the summaries. If calls are recorded and callers know, listen to your first 20.

False claims about your competence

A wrong answer from an AI is one thing. For an electrician, it can be a false statement about what you're competent to do.

A Canadian tribunal in Moffatt v Air Canada held the airline responsible for wrong information from its website chatbot, and rejected the idea of the bot as a separate entity. It doesn't bind a UK court, but I wouldn't fancy "the AI said it" as a defence here.

Where it can go wrong:

• Registration. "Yes, we're NICEIC registered" when you're with another scheme. Claiming approval you lack is banned under the DMCC Act 2024.
• Scope. "Yes, we fit EV chargers" when you don't, or "we do solar and batteries".
• Certificates. "You'll get a certificate today."
• Prices. "A consumer unit is £400" is a promise you never made.
• Law. Telling a landlord what's required, or what counts as a C2.
• Repairs. "Try resetting the RCD" could make things worse.

The fixes are dull and they work. Give it a written list of what you do and don't do, plus your exact scheme wording. Give it price ranges, or have it say you'll confirm. Ban fault-finding and legal advice, except your agreed safety lines. Check summaries each week and correct what's off.

Flat 2 or flat 12?

Addresses are where an error costs most, and block addresses on landlord work are worse still. On a bad line, flat 2 and flat 12 sound alike.

No independent figure for AI receptionists mishearing addresses exists that I could find. There is a general warning, though. A June 2025 preprint testing speech recognition on Newcastle English recorded a word error rate of about 32% for one system's UK English setting, and it reports higher error rates for speakers from Northern England and Northern Ireland. That used recorded speech, not phone calls, so take it as a reason to try your own customers' voices.

• Have it read the address back.
• Text the details over for the customer to correct.
• Test it on poor mobile signal, with people who sound like your customers.
• Make sure every call gives you a summary and the caller's number.

Privacy and call recording

Lots of AI tools record or transcribe calls, and a caller's voice and address are personal data under UK law. Tenants may ring you as well, and they never chose you.

• The ICO's guidance says callers must be told if you're recording, and why. It sits in a section on monitoring workers and is under review, but I'd follow it.
• Your privacy notice should explain how AI is used and who handles transcripts.
• Someone can ask for recordings that hold their information.

Providers differ. ServiceM8's help page says calls are logged with a recording, and Fasthosts says it doesn't record. Ours can record calls, and the greeting says so. Ask anyone you're considering what's kept and for how long.

As for saying it's an AI on an inbound call, I found no UK rule that requires it, though I couldn't check the latest position, so say it anyway. Ringing out is another matter, because the ICO requires prior consent for automated marketing calls. Don't point an AI at landlords for cold calling.

The bill, and the call-back that never happens

Many of these products charge by call or usage. Find out what counts as a call, whether spam is charged, and what happens above your allowance. Our plans include a monthly usage credit, and any extra goes on your bill.

The likeliest failure has nothing to do with AI, I'd expect. Twenty captured leads are worthless if nobody rings them. Fix a daily time for call-backs, and use the follow-ups in the text templates. The rest of the chain is in why electricians lose work after the first call.

How ours compares

So you can hold it against the above:

• It says it's an AI at the start of the call.
• It answers from what you've told it about your services, areas, prices and hours.
• It takes the caller's details, and you get a summary.
• On its own, it doesn't book. You call back and book. The full AI Business Engine adds booking.
• It can record calls, and the greeting says so.
• You can have a separate emergency number and an enquiry number.
• On a number the AI answers, it only knows a call is urgent if the caller says so. Then it tries to transfer the call to you. If you can't pick up, it takes details and puts them in your summary.

The safety wording above is yours to agree with us at set-up, then to test before it goes live and after any change. It's your business and your customers, so don't take anyone's word for it, ours included.

No product removes these risks, ours or a rival's. Whether it's still worth having is covered in our honest view.
