There are four real options: a decibel sensor, occupancy/people-counting, waiting for a neighbour to call, or doing nothing until a complaint arrives. Airbnb’s policy permits a decibel monitor indoors if you disclose it, and bans indoor cameras and audio recorders outright. Occupancy counting is not addressed separately. Here’s what each option can and cannot actually tell you.
What are the options for noise monitoring in a UK holiday let?
| Option | What it measures | Records audio | Airbnb policy status |
|---|---|---|---|
| Decibel sensor | Sound level and duration | No | Allowed indoors, disclosed, not in bedrooms/bathrooms |
| Occupancy/people-counting | Estimated nearby device count | No | Not addressed separately |
| Neighbour phone call | Noise reported after the fact | N/A | N/A |
| Doing nothing | Nothing, until a complaint arrives | N/A | N/A |
Each row answers a different question. None of them answers all of the questions a host actually has.
What does a decibel sensor actually tell you?
A decibel sensor measures sound level and how long it lasts. Airbnb’s help article on this says: “Noise decibel monitors are devices that assess sound levels and their duration but do not record audio.” Manufacturer documentation backs this up from the device side. Minut’s own noise monitoring page states: “Minut sensors measure decibel levels only. No audio is ever recorded or transmitted.”
That’s the ceiling of this category. It gives you a number and a duration. It doesn’t tell you who’s in the room. It doesn’t tell you what’s being said. It doesn’t tell you whether a spike is a party or a vacuum cleaner. A decibel sensor flags that a threshold has been crossed. What you do next, message the guest, call a key holder, end the booking, is still a decision you have to make.
What does occupancy/people-counting tell you?
Some decibel sensors also estimate headcount by counting nearby wireless devices. Minut’s documentation on this feature is direct about the limits. It says: “Device count is an estimate, not an exact headcount.” It also says the feature “does not count guests without active wireless devices in the unit.” A guest who leaves their phone in another room, or doesn’t carry one, isn’t counted.
The same mechanism, counting Wi-Fi probe requests, can inflate the number too. One guest carrying two devices reads as two. A neighbouring property’s devices picked up by the sensor read as extra guests who aren’t there. So occupancy counting answers a narrower question than it sounds like. It’s an estimate of nearby device signals, not a headcount of people in a room. These specifics are documented for Minut’s Crowd Detect feature specifically. Other decibel sensors sold in the UK that offer similar counting may work differently, and that hasn’t been checked against each one’s own documentation.
What about waiting for a neighbour to call?
This isn’t a device. It’s what happens by default if you run no monitoring at all. A neighbour gets disturbed, decides it’s bad enough to act, and calls you, calls Airbnb, or calls the council.
Local authority data gives some sense of how often that call actually happens. The CIEH recorded 326 complaints linked to properties operating as holiday lets, including Airbnbs, across England and Wales between October 2024 and September 2025. That figure counts complaints about holiday-let properties generally. It doesn’t isolate parties from other causes, such as plant equipment or voices. It isn’t a party-frequency statistic. What it does confirm is that neighbours do call, often enough for a national body to track it.
The problem with relying on this as your only system is timing. A phone call is a lagging indicator. By the time it arrives, the noise has already happened. The neighbour relationship has already taken a hit. You’re managing the aftermath, not the event.
What about doing nothing?
This is a real choice, not a strawman. Some hosts pick it deliberately, usually because a property is detached, low-risk, or the disclosure and monitoring involved don’t feel worth it for that particular listing. It costs nothing to set up. It tells you nothing until someone, usually a neighbour, has already been disturbed enough to act.
Is a decibel sensor allowed under Airbnb’s rules?
Yes, with conditions. Airbnb’s help article says: “Home hosts are allowed to have noise decibel monitors in the home’s interior as long as the host discloses their presence and they are not located in bedrooms, bathrooms, or sleeping areas.” Three things have to be true at once. You disclose it in your listing. It measures sound only. It isn’t sited in a bedroom, bathroom, or other sleeping area.
Why not just use a camera or audio recorder instead?
Because Airbnb bans it outright, with no exceptions for being switched off. The same help article says: “Hosts are not allowed to have security cameras and recording devices that monitor any part of a home’s interior, such as the hallway, bedroom, bathroom, living room, or guest house, even if they’re turned off or disconnected.”
UK data protection guidance points at the same conclusion from a different angle. The ICO’s guidance on surveillance systems says: “In most situations, the use of audio recording, particularly where it is continuous, is considered more privacy intrusive than purely visual recording.” Its practical advice is blunt: “You should switch off by default any capability to record audio.” Between Airbnb’s policy and the ICO’s guidance, recording conversations inside a guest’s accommodation isn’t a grey area worth testing.
Which option fits your property?
If you want an early warning that a threshold has been crossed, without hearing what’s said, a decibel sensor is the option Airbnb’s policy actually accommodates. If you want a rough sense of how many devices are active in a property on top of that, occupancy/people-counting can add it, with the estimate caveats above built in. Treat the number as a signal, not a headcount. If your property is low-risk and you’re comfortable reacting after the fact, relying on a neighbour’s call is a real, if reactive, choice. Doing nothing is also a choice, as long as you’re accepting what it costs you in response time.
Disclose a decibel sensor in your listing if it measures sound indoors. Don’t reach for a camera or audio recorder as a shortcut: it’s against Airbnb’s policy and against UK data protection guidance.
What if you don’t want to manage this yourself?
If you’d rather this wasn’t something you had to watch personally, AirPilot’s Noise Monitoring sits alongside our Smart Access service for hosts and property managers across England, Scotland and Wales. We don’t fit cameras or audio recorders, for the reasons set out above. See /pricing for how the service is structured, or book a demo if you’d rather talk it through. If you’re not ready for either, our free guide is a reasonable place to start.
