Can you film the site perimeter from a public highway? UK Construction Sites CCTV rules explained 2026
Can recording the surrounding public highway breach GDPR when monitoring a construction site?
When installing CCTV on a construction site, you must carefully assess whether the camera's field of view (FoV) captures areas outside the site boundary, such as the public highway. If the camera records public areas, you are collecting images of individuals in a public space, which triggers GDPR compliance requirements. Under the Data Protection Act 2018, the data collected must be necessary, proportionate, and minimised. It is critical that you implement clear signage informing the public that they are being recorded and detailing the purpose of the monitoring. Furthermore, the data retention policy must strictly limit how long images of passersby are kept, often recommending deletion after 24 hours unless specific evidence is required for an investigation. To mitigate legal risk, consider using directional cameras or physical barriers to ensure the FoV focuses solely on the site's immediate entrance and works area.
More questions about Construction Sites:
Do I need a specific permit to film workers entering and leaving the site?
Generally, simply monitoring the ingress and egress points of your own workers does not require a specific local authority filming permit, provided the cameras are solely owned and operated by the site owner or principal contractor. However, if the camera installation involves mounting equipment on shared property or significantly obstructing a public right of way, you must consult with the local council or the Highways Agency. Always ensure that the signage detailing the surveillance is highly visible, mentioning the purpose of the filming and providing clear details of the Data Protection Officer (DPO) contact.
Can I record workers' faces if the CCTV is only for theft prevention?
While theft prevention is a legitimate commercial interest, recording workers' faces always constitutes recording personal data. To remain compliant with the ICO guidelines, you must demonstrate that the recording of faces is absolutely necessary for the stated purpose and that less intrusive methods (such as physical security patrols or access control logs) have been exhausted. If the footage is only used to identify a stolen tool, masking faces or only recording the item being stolen is best practice. Always review your retention policy to ensure facial images are not kept longer than necessary.
Is it illegal to point a camera at a site when no work is taking place?
No, it is generally not illegal for the site owner to maintain surveillance cameras, even when the site is dormant or inactive. However, the data protection principle of 'storage limitation' still applies. If the cameras are recording continuously, the collected data must be stored securely and only for the time necessary to maintain site security and asset protection. You must update your signage to reflect the current operational status of the site, maintaining transparency regarding the continuous monitoring capability.
Must I provide CCTV footage to police if they request it?
You are not automatically obliged to hand over CCTV footage to the police simply because they request it. Under UK law, you must assess the lawful basis for the request and ensure it is proportionate to the alleged crime. It is highly recommended that you document all requests thoroughly, noting who requested it, the date, and the specific reason for the footage. If the police insist on the footage, it is advisable to consult with your legal professional or the site's insurance provider before releasing any data.
