Documenting noise incidents

Keep a log of dates, times, duration, source, and perceived severity. A consistent record strengthens both informal neighbor requests and formal complaints.

What is a noise diary

A noise diary is one of the most important pieces of evidence in a statutory nuisance investigation. Most UK councils ask complainants to keep one before deciding whether to deploy noise monitoring equipment or take enforcement action.

The diary should be factual, consistent, and objective. Its purpose is not to prove that noise occurred—that may later be done through monitoring or witness visits—but to show the frequency, duration, timing, and impact of the disturbance.

What to record

For each incident, include:

Field Example Date Saturday 25 July 2026 Start time 14:05 End time 18:45 Location of noise Outdoor music event at XYZ Park Type of noise Amplified live music, bass, crowd noise Description Continuous amplified music with heavy bass; announcements between acts Impact Unable to work from home; conversation indoors difficult; windows had to remain closed Severity e.g. 1–10 (optional, but useful if used consistently) Weather (optional) Warm, light breeze towards residential area Record the impact—not just the noise

Under the Environmental Protection Act 1990, the key question is whether the noise amounts to a statutory nuisance. This depends not only on how loud it is, but on how it affects the ordinary use and enjoyment of your home.

Examples of relevant impacts include:

Sleep disturbed or impossible. Unable to hold a normal conversation indoors. Television or radio had to be turned up significantly. Windows had to remain closed because of the noise. Unable to work from home. Unable to use the garden. Child or baby repeatedly woken. Stress, headaches, or inability to concentrate.

Avoid vague statements such as:

"It was unbearable."

Instead, write:

"Bass was audible throughout the house with all windows closed. I was unable to participate in a work video call without muting my microphone because the music could be heard by other participants."

This provides concrete evidence of the effect.

Record gaps and changes

If the noise changes during the event, note that too. For example:

Time Observation 14:00 Music started 15:20 Bass noticeably increased 16:10 Short break 16:30 Music resumed 18:45 Music ended 19:15 Audience dispersal continued with shouting and car doors

This level of detail can help investigators understand the nature of the disturbance.

If it's a recurring event

If the same venue hosts repeated events, include information such as:

Whether it was advertised as a concert or festival. Approximate attendance (if known). Whether this is a recurring event. Whether previous complaints have been made.

Patterns over weeks or months may strengthen the case that the issue is persistent rather than isolated.

Supporting evidence

Many councils now accept additional evidence alongside the diary, although they rarely rely on recordings alone because phones do not accurately represent perceived loudness.

Useful supporting evidence may include:

photographs showing the event or speaker direction; videos illustrating the character of the noise (rather than its volume); screenshots of event advertisements showing advertised hours; copies of correspondence with the organiser or council; notes of any responses received.

Keep the original files with their timestamps where possible.

Good practice

A good noise diary should:

be completed as soon as possible after each incident; use actual times rather than estimates where feasible; distinguish between music, bass, crowd noise, fireworks, etc.; describe facts rather than opinions; be kept consistently over several weeks if the issue is ongoing. Example entry Field Entry Date Saturday 25 July 2026 Start 14:02 End 22:37 Source Amplified outdoor music event at the local recreation ground Description Continuous amplified live music with pronounced bass. Speakers appeared directed towards nearby housing. Music clearly audible throughout the house despite windows and doors being closed. Effect Unable to work from home between 14:00 and 17:00 because music was audible during online meetings. Could not sit in the garden. Television volume increased substantially. Child woke twice after 21:30. Other observations Audience leaving until approximately 23:10, with shouting and vehicle noise. Wind light and blowing from the venue towards the house.
