Voice AI Compliance in the UK: Why Getting It Right Matters

Voice AI is new, exciting, and let's be honest, a bit scary.

We've all been on the receiving end of the automated voice system that asks what you want and then completely ignores your answer. And let's not even start on robocalls and auto-diallers that ring, then leave that excruciating pause before a recorded message kicks in.

AI voice services come with a myriad of opportunities, challenges, and risks. But the genie is out of the bottle. A simple illustration of how far and fast this has moved: Tesla now has Grok hands-free built into their cars (tesla.com/support/grok).

Like it or hate it, AI voice is here to stay. It's dramatically better than it was just twelve months ago and as the capabilities keep improving, it'll be exponentially better again in another twelve months.

But with opportunity comes challenge. In Europe and the UK we have GDPR. The UK has PECR. TPS and CTPS checking is a legal requirement for outbound calling. This isn't a wild west free-for-all. There are real rules, real regulators, and real consequences for getting it wrong.

The UK framework already exists. Businesses don't need to wait for new legislation. They need to understand how existing rules apply to something that didn't exist when those rules were written.

Disclosure first. If someone is speaking to an AI, they should know within the first few seconds. Not when they think to ask. Not in a T&C nobody reads. From the off. Most people are genuinely fine with AI once they understand what they're dealing with. The friction comes when businesses try to pass it off as something it isn't.

PECR is where most people come unstuck. The assumption is that AI voice agents fall into the same bucket as recorded marketing messages, the kind that require prior consent. That's not necessarily the case. A conversational AI that listens, responds in real time, handles objections, and changes tack based on what the caller actually says is a different thing from a pre-recorded blast. That distinction has real compliance implications.

That said, it's not a green light to call whoever you want.

TPS and CTPS screening isn't optional. If someone has registered their number, that preference stands unless you have clear consent to override it. Interestingly, this is one area where good technology can actually improve on human processes. Automated screening doesn't forget, doesn't skip steps when it's busy, and creates an audit trail that a spreadsheet never will.

When we built ExpoCall we made a decision early on: compliance can't be something users have to remember to do themselves. So it's built into the platform. Every number is screened against TPS and CTPS before a call goes out. The system won't dial outside working hours. That's not a setting, it's a hard limit. If someone withdraws consent during a call, that's captured and they're suppressed from future calling automatically. And there's a cross-client check that prevents the same number being called twice in the same day by different clients on the platform. That last one is easy to overlook but it matters. Two AI calls in one day from different companies running on the same infrastructure is a reputational problem for everyone involved, not just the individual client.

The ICO's position on AI has been pretty consistent: fairness, transparency, accountability. None of that is new. What changes with AI is the scale at which things can go wrong if those principles aren't taken seriously. Mistakes don't happen one at a time anymore.

The businesses that'll get the most from Voice AI probably won't be the ones making the highest volume of calls. They'll be the ones who can show they're in control of what they're doing. Proper audit trails, genuine opt-out mechanisms, and a clear path to a human when the conversation needs one.

The payments industry went through a version of this about a decade ago. The companies that came out ahead weren't the ones that fought compliance at every turn. They were the ones that built it in and used it as a reason for customers to trust them.

That's the bet we're making with ExpoCall. And honestly, I think it's the only approach to Voice AI that holds up. For the businesses deploying it, for the people on the other end of the call, and for an industry that really can't afford another wave of nuisance call scandals.
