Can my CCTV legally film my neighbour's property?

Home cameras often catch more than just your own land, and a neighbour's garden or windows can end up in shot. Whether that is acceptable depends on how much you capture, why, and how you handle it.

Legal, but with responsibilities

The honest answer is that home CCTV which films part of a neighbour's property is not in itself unlawful, but it stops being a private matter and becomes regulated. The ICO, the UK's data protection regulator, is clear that once your cameras capture identifiable people outside your own boundary, your system is covered by UK GDPR and the Data Protection Act 2018. That means you are now processing other people's personal data and must do so responsibly.

This catches a great many homeowners by surprise, because wide-angle doorbell and security cameras routinely take in a neighbour's drive, frontage or even a window. The point is not that you must never capture any of it — that is often unavoidable on a tight residential street — but that you should be able to account for it. The ICO's expectations are about reasonableness and proportionality, not an outright ban on any footage that strays over the fence.

The four things the ICO expects

If your cameras do capture a neighbour's property, the ICO's domestic CCTV guidance sets out clear duties. First, justify the capture: you should have a genuine reason, such as protecting your own home, rather than monitoring a neighbour out of nosiness or a grudge. Second, minimise: angle cameras downward and inward, narrow the field of view, and use the privacy masking feature most modern systems offer to black out areas you have no business recording, such as a neighbour's window or garden.

Third, be transparent: put up a clear sign that CCTV is in operation, and be open if a neighbour asks what your cameras cover. Fourth, handle the footage properly — store it securely, keep it only as long as you genuinely need it, and respond to a subject access request if a neighbour asks for footage of themselves. Following these steps generally keeps you well within the law and, just as usefully, defuses most neighbour disputes before they start.

When it can become harassment

There is a line between incidental capture and targeted surveillance. Cameras sited to protect your own home that happen to catch the edge of a neighbour's drive are one thing. Cameras deliberately positioned to monitor a neighbour's movements, comings and goings, or private garden — particularly during a dispute — are quite another. In a well-known English case, a court found that excessive and intrusive use of domestic cameras and audio recording aimed at a neighbour amounted to a breach of data protection law and could contribute to harassment.

That does not mean a neighbour can demand you remove every camera that glimpses their property, but it does mean intent and proportionality matter. If your purpose is genuine security and you have minimised capture, you are on solid ground. If the cameras exist mainly to surveil someone, you risk a complaint to the ICO, a civil claim, or action under the Protection from Harassment Act 1997. Keeping the focus firmly on your own property is the simplest protection.

How to keep things neighbourly

The most effective approach is usually the simplest: site your cameras so they cover your own property as fully as possible and your neighbour's as little as possible. Mount cameras high and angle them down, choose narrower lenses where you can, and apply privacy masking to anything beyond your boundary. A short, polite conversation with neighbours about what your cameras cover often prevents misunderstandings, and a visible CCTV sign satisfies the transparency expectation.

If a neighbour raises concerns, take them seriously and be willing to adjust angles or masking. If you are the one worried about a neighbour's camera pointing at your home, the same guidance applies in reverse — and the ICO and Citizens Advice both offer routes for raising it. Most CCTV disputes between neighbours are resolved by minimising capture and talking, long before any formal complaint becomes necessary.

It also helps to keep a sense of proportion about what the rules require. The ICO does not expect cameras to capture absolutely nothing beyond your fence — on a typical residential street that would be impossible, and a small amount of incidental overlap is accepted as part of ordinary home security. What matters is that you are not deliberately recording a neighbour's private life, that you have taken reasonable steps to limit what you capture of their property, and that you can explain your set-up if asked. Reasonableness, not perfection, is the standard.

Documenting your own good practice is a quiet safeguard. If you make a note of where your cameras point, which areas you have masked, and why the system is there, you put yourself in a strong position should a concern ever be raised. A homeowner who can calmly show that cameras are aimed at their own door, that a neighbour's window is masked out, and that footage is stored securely and not kept indefinitely has done everything the ICO asks. That clarity is usually enough to satisfy a worried neighbour and to demonstrate, if it ever came to it, that the system is being used fairly and for genuine security rather than surveillance.
