It's one of the first questions we get from tradespeople. Not "does it work?" or "what does it cost?", but "am I actually allowed to do this?" Fair enough. You're putting a voice that isn't you on your business number, and if something goes wrong it's your name on the van.
The short answer is yes. Using AI to answer inbound calls to your business is legal in the UK. What matters is how you do it: being honest with callers, handling their details properly, and making sure an emergency never gets stuck with a robot. This guide goes through each of those in plain English.
It's general guidance, not legal advice. If you're doing anything unusual, or you work in a regulated area beyond normal trade work, check with the ICO or a solicitor.
The Short Version
- Answering your own business calls with an AI receptionist is legal. There's no licence to apply for.
- Tell callers they're speaking to an AI. It's the honest thing to do, and pretending otherwise could fall foul of consumer protection law.
- If calls are recorded or transcribed, that's personal data. UK GDPR applies, the same as it does to your invoices and your customer list.
- Most businesses that handle customer data need to pay the ICO's data protection fee. Many sole traders already should be.
- Outbound is different. Using AI to ring people with offers has its own, much stricter rules.
- Emergencies need a clear route to a human or the right emergency line.
Do You Have to Tell Callers It's AI?
At the time of writing there's no single UK law written just for AI phone assistants that says "you must announce it". But that doesn't mean you can hide it.
UK consumer protection law, now set out in the Digital Markets, Competition and Consumers Act 2024, bans misleading practices. If a caller would reasonably expect to be talking to you or a member of your staff, and the voice says "Yeah, this is Dave" when it isn't Dave, you're on shaky ground. It's also just bad for business. People don't mind AI nearly as much as they mind being fooled by it.
The simple fix is to say it up front. Something like:
"Hi, you've reached Smith Plumbing. I'm the AI assistant, Dave's on a job. I can take your details and book you in, or get him to call you back."
That one line covers you, and in our experience callers get on with it quickly once they know. At Slotby we disclose it on every call. We wouldn't do it any other way.
Recording and Transcripts: Where UK GDPR Comes In
Most AI call handling software records the call, transcribes it, or both. That's how you get a written summary on your phone afterwards. A recording or transcript with someone's name, number, address and a description of their leaking toilet is personal data, so UK GDPR and the Data Protection Act 2018 apply.
That sounds heavier than it is. For a small trade business it mostly comes down to a few things.
Have a Reason and Tell People
You need a lawful basis for using the data. For booking a job someone has rung you about, that's usually straightforward: you're taking steps to enter a contract with them at their request, or you have a legitimate interest in keeping an accurate record of what was asked for.
You also need to tell people what you're doing. The usual way is a short line in the greeting ("calls are recorded so we get your details right") plus a privacy notice on your website that says what you collect, why, who processes it and how long you keep it. The ICO has free templates for small businesses.
Keep Only What You Need
Callers sometimes tell you more than you need. "My mum's 89 and on oxygen, the heating's gone off." That detail matters for priority, but health information is special category data, so treat it with care. Don't keep recordings forever just because you can. Pick a sensible retention period and stick to it.
Check the Provider Properly
When a provider records calls for you, they're usually acting as your data processor. The law expects a written contract covering that, often called a data processing agreement. Any decent provider will have one ready. Ask:
- Where are recordings and transcripts stored, and for how long?
- If data goes outside the UK, how is that transfer covered?
- Can I delete a caller's data if they ask?
- Is the data used to train anyone's AI models?
If a provider can't answer those clearly, that tells you something.
The ICO Data Protection Fee
Separate from all the above, most organisations that process personal data have to pay an annual data protection fee to the Information Commissioner's Office. Plenty of sole traders don't realise this, even before AI comes into it. If you keep customer names and numbers on your phone or in invoicing software, it's worth checking.
The ICO has a short self-assessment on whether you need to pay. It takes a couple of minutes, and the fee for a small business is modest.
Inbound Is Not the Same as Outbound
This is where people sometimes get mixed up. The rules people have heard about, nuisance calls, robocalls and fines, are mostly about outbound marketing.
Under the Privacy and Electronic Communications Regulations (PECR), using automated calling systems to make marketing calls needs the person's prior consent. Ofcom and the ICO take that seriously. An AI receptionist that only answers calls people make to you is a completely different thing. The customer chose to ring you.
If you ever want to use AI to call old customers about boiler services or special offers, stop and read the ICO's guidance on marketing calls first. Answering the phone is easy territory. Cold calling with a bot is not.
Emergencies and Safety
There's no specific law that says an AI receptionist must handle emergencies a certain way. But you have a duty of care to the people you deal with, and common sense does a lot of the work here.
Set clear rules for the calls that can't wait:
- Gas smells. The assistant should tell the caller to leave the property and ring the National Gas Emergency Service on 0800 111 999 straight away, not book them in for Thursday.
- Danger to life. Anything involving fire, electrocution or someone being hurt should go to 999.
- Urgent but not dangerous. Burst pipes, no water, flooding through a ceiling. These should reach you fast, by a text or a transferred call, with clear advice to the caller in the meantime, like where to find the stopcock.
We go into this in more detail in does an AI receptionist work for emergency plumbing calls. The same thinking applies to electricians, heating engineers and locksmiths.
Being Fair to Every Caller
Some callers will struggle with any automated system. People with hearing loss, some older customers, people with speech differences. The Equality Act 2010 expects service providers to make reasonable adjustments for disabled people, and good practice is simple: always offer another way through. A callback from you, a text, or an email address.
A well set-up AI receptionist should never be a dead end. If someone says "I want to speak to a person", the right answer is "of course, I'll get him to ring you", not a loop.
Your Name Is Still on It
One last thing that's more about reputation than law. Whatever the AI says, customers will treat it as you saying it. If it promises a same-day visit you can't make, or quotes a price you'd never charge, that's on your business.
So keep the rules tight. Let it take details, book into slots you've chosen, and pass on urgent jobs. Don't let it invent prices or make promises outside what you've told it. Most decent call handling services, AI or human, work this way anyway.
A Quick Checklist Before You Switch It On
- The greeting says it's an AI assistant and, if relevant, that calls are recorded.
- Your website has a short privacy notice covering call recordings.
- You've checked whether you need to pay the ICO fee.
- You have a data processing agreement with your provider.
- There's a sensible retention period for recordings and transcripts.
- Emergency rules are set: gas, 999 situations and urgent jobs.
- Callers can always ask for a human callback.
- You've rung your own number and listened to a few test calls.
That's genuinely most of it. Plenty of UK tradespeople already use some form of AI call handling, and the ones who do it well are open about it from the first second of the call.
