ICO: Guidance for Consumer Internet of Things Products and Services

On 16 June, the ICO published their first draft guidance for organisations across the consumer Internet of Things (IoT) value chain.

This guidance is informed by research conducted last year into public views of smart products, which explored participants’ understanding and expectations as to how their personal data is collected and handled by these devices. As a result, the guidance sets out how organisations can collect and utilise consumer data safely and appropriately.

Scope of the Draft Guidance

The draft guidance focuses specifically on the processing of personal information by organisations providing consumer IoT products, such as smart speakers, watches, fitness trackers, home hubs, and connected appliances. It does not cover connected and autonomous vehicles, smart meters, smart cities, or industrial and enterprise IoT applications.

The guidance addresses a series of questions:

  • What information do Internet of Things (IoT) products use?
  • How do we ensure accountability in IoT products?
  • How do we ensure our IoT products process information lawfully?
  • How do we ensure our IoT products process personal information fairly?
  • How should we tell people what we’re doing?
  • How do we ensure accuracy in IoT?
  • How do we help people exercise their rights?

The guidance focuses on the principle of data protection by design and default. At different stages in the manufacturing process, any organisation might be a controller, joint controller or a processor, with their roles and responsibilities varying accordingly. Establishing these roles is extremely important for determining accountability and therefore who is responsible for data protection obligations. This is particularly pertinent for products that process children’s information, which should also comply with the ICO’s children’s code.

Obtaining consent from users is another key theme of the guidance, with an emphasis on ensuring this consent is freely given and unambiguous. The guidance offers a number of practical steps for organisations to help fulfil these requirements, including avoiding unnecessarily disruptive prompts, and refraining from using option labels that could influence users into consenting through emotionally charged language that invites guilt or other negative emotions.

A major strength of this guidance is the extensive usage of practical examples, including visuals depicting the set-up of a smart watch.

Transparency is another core focus, with the guidance noting that ‘being transparent about your use of people’s personal information is closely linked to fairness’. Organisations must clearly inform users of their intent to process their personal data, regardless of the type of IoT product, and provide a clear explanation of how they intend to use said data. Beyond this, the guidance invites organisations to consider how to present this information in the most appropriate and accessible manner, for instance identifying the appropriate point in a user journey to surface it.

On data retention, the guidance sets out that personal data should not be stored for longer than is necessary. The ICO recognise it is not possible to mandate specific time frames, as these vary depending on the situation and purposes for processing the data, but strongly encourage organisations to regularly review their retention periods. Similarly, if an IoT product involves data sharing with other organisations, there should be a mutually agreed process for determining how long the data is retained and when it should no longer be shared.

The ICO have also looked to how organisations can empower their users to exercise their rights, clarifying their position on:

  • Right of access - Users have a right to see the information organisations collect and share about them, and can access this through issuing a subject access request. Organisations should work to ensure this process is not “unnecessarily cumbersome” and consider when users are most likely to issue such requests.
  • Right to rectification - Users may request correction of any inaccurate personal information held about them, with organisations expected to act within a month. The guidance also invites companies to consider whether users should have the tools to amend such information themselves, where appropriate.
  • Right to erasure - Users have a right to erasure, also known as the right to be forgotten, which should be adhered to unless specific circumstances apply, as outlined in the ICO’s right to erasure guidance. This right should be made clear and offered in the “most appropriate and logical way” for the user. Beyond this, it should be made clear that simply deleting an app or account does not necessarily erase their data.
  • Right to data portability - When a user wishes to transfer their personal data from one IoT product to another, organisations must provide this data in a usable format, and transmit this personal information to the new provider, if it is technically feasible.
  • Right to object - Users may object to the processing of their personal information at any time, although the circumstances where this right applies depends on the purposes for processing and the lawful basis used. This is, however, an absolute right when it pertains to direct marketing purposes, and therefore organisations must inform people how to object to targeted online advertising.

The draft guidance is now subject to consultation until the end of Sunday 7 September 2025. To share any feedback or questions on the draft guidance, please reach out to Audre ([email protected]) and Dani ([email protected]).
