What are typical noise limits for construction sites in the UK?

Construction noise limits vary depending on location and local authority rules, but in general, daytime site noise should not exceed around 65–75 dB(A) at the nearest occupied building. This level is similar to the sound of busy traffic or a vacuum cleaner — noticeable but not harmful over short periods.

For sensitive sites like schools or hospitals, councils might set lower limits, sometimes closer to 55 dB(A). Night work and weekend operations are usually restricted to even lower thresholds, and some projects must follow BS 5228, the British Standard that sets out guidance on managing construction noise.

It’s important to remember that limits aren’t just about volume — they also consider how long the noise lasts and when it occurs.
