BS 5228:2009 – What Contractors Need to Know
BS 5228 is the British Standard for managing noise and vibration on construction sites. Here's an accessible summary of what it requires.
BS 5228:2009 is the British Standard Code of Practice for Noise and Vibration Control on Construction and Open Sites. It is the primary technical guidance that councils, contractors, and courts refer to when assessing construction noise.
What is BS 5228?
BS 5228 is split into two parts:
- Part 1: Noise – covers noise prediction, assessment, and control measures
- Part 2: Vibration – covers vibration from construction activities
It is not a legal requirement in itself, but it is referenced by the Control of Pollution Act 1974 and local planning conditions, making compliance effectively mandatory on most significant sites.
Key Principles
1. Noise Prediction
Before work begins, contractors should predict noise levels at nearby sensitive receptors (homes, schools, hospitals) using guidance in BS 5228. This informs the Construction Management Plan (CMP).
2. Best Practicable Means (BPM)
The Act requires contractors to use Best Practicable Means to minimise noise. BS 5228 provides the framework for what BPM looks like in practice:
- Selecting quieter plant and equipment
- Acoustic screening at site boundaries
- Scheduling the noisiest work during daytime hours only
- Regular maintenance of equipment
3. Noise Limits
BS 5228 provides recommended noise limits depending on the area type:
| Area | Daytime Limit (LAeq) |
|---|---|
| Predominantly residential | 70 dB |
| Mixed residential/commercial | 75 dB |
| Predominantly industrial | 80 dB |
4. Notification to Neighbours
Best practice under BS 5228 includes notifying nearby residents in advance of particularly noisy work, giving them the site manager's contact details.
Section 61 Prior Consent
Contractors carrying out significant works are strongly advised to apply for Section 61 Prior Consent from the local council before starting. This formalises agreement on working hours, methods, and noise limits — providing legal protection if complaints arise.
