How to Record Construction Noise Evidence Your Council Will Accept
Key takeaways
- Record consistently over weeks, not once: officers look for frequency, duration and time of day.
- Log the start and end time of each episode, not just that noise was heard.
- Smartphone levels are indicative, not certified, so pair them with written detail and video.
- Keep the original files unedited and back them up before sending anything to the council.
Environmental Health Officers are not short of complaints about construction noise. What they are short of is evidence they can act on. The difference between a complaint that gets a site visit and one that gets a polite reply is almost always the quality of the record.
What an officer actually needs
Under the Environmental Protection Act 1990, a council must decide whether noise is a statutory nuisance — an unreasonable and substantial interference with the use of your home. To judge that, an officer needs to know:
- When the noise happens, and whether it is predictable
- How long each episode lasts
- How loud it is relative to the area’s normal background
- Whether it interferes with sleep, work or normal use of your home
The five-part log
Keep a simple written record for each episode. A notebook works, but a spreadsheet with one row per episode keeps it consistent.
- Date and start time. Note the exact minute the noise began.
- End time. If it ran all afternoon, say so. Duration matters more than intensity.
- Noise type. Drilling, hammering, machinery, demolition, reversing alarms, or a combination.
- Location. Where you were and where the sound came from.
- Impact. “Could not take a work call between 09:15 and 10:00” is more useful than “very loud”.
Taking measurements that help
Smartphone sound level apps are not calibrated instruments, and no officer will treat them as proof. They are still valuable as corroboration when used consistently.
- Take readings from the same position every time
- Record at least 60 seconds per measurement and note the average, not the peak
- Capture the time on screen with a screenshot
- Note the weather: wind on a microphone inflates readings significantly

Video is your strongest single item
A 30-second clip that shows the site, the activity and your own property boundary is worth a great deal. It demonstrates that the noise is actually coming from the site you are complaining about.
Do not edit the video. Export it from the phone and keep the original.
How to send it
Send a short covering email with the log attached as a spreadsheet or PDF. State what you want: an assessment of whether the noise amounts to a statutory nuisance, and a site visit during the activity in question.
If the council does not act and you believe the noise is a statutory nuisance, you retain the right to bring proceedings yourself in a magistrates’ court under Section 82 of the Environmental Protection Act 1990, after giving the person responsible at least three days’ written notice (the notice period for noise under section 82(7)).
Frequently asked questions
Will the council accept phone recordings?
Usually as supporting evidence. Councils may rely on their own officer measurements for formal action, but a consistent phone-based log is frequently what prompts that visit in the first place.
How long should I keep logging before complaining?
Two to three weeks of consistent entries covering different times of day is generally enough to show a pattern. If the noise is intermittent, log for longer so the quieter days do not mask the problem.
Should I complain to the site as well as the council?
Yes, and keep a record of it. Many sites will adjust working methods once they know a neighbour is affected, and a documented site complaint shows the council you have tried to resolve it directly.

Can a noisy machine on a building site be made quieter, and what can you ask for?
Often, yes. Contractors can fit shrouds or enclosures to the noisiest machines, put acoustic barriers around the work area and boundary, and plan noisy work for less sensitive hours.…

As a rule of thumb, an acoustic wall should stand about 1.5 m higher than the top of the noise source. A generator 2.5 m tall therefore needs a wall about 4 m high. This guide explains…
